TI: Purification and characterisation of an extracellular fructan beta-fructosidase
from a Lactobacillus pentosus strain isolated from fermented fish.
AU: Paludan-Muller-C; Gram-L; Rattray-FP
SO: Systematic-and-Applied-Microbiology; 25 (1) 13-20, 31 ref.
AB: An extracellular fructan beta-fructosidase (exo-inulinase; EC 22.214.171.124)
produced by Lactobacillus pentosus B235 (isolated as part of the dominant
microflora from a garlic containing fermented fish product) was purified
and characterized. L. pentosus B235 was grown in a chemically-defined
medium with inulin as the sole carbohydrate source. The extracellular
fructan beta-fructosidase produced was purified to homogeneity from the
bacterial culture supernatant by ultrafiltration, anion exchange chromatography
and hydrophobic interaction chromatography. The mol. wt. of the enzyme
was estimated to be approx. 126 kDa by gel filtration and SDS-PAGE. The
purified enzyme had highest activity for levan (a beta(2Right arrow6)-linked
fructan), but also hydrolysed garlic extract (a beta(2Right arrow1)-linked
fructan with beta(2Right arrow6)-linked fructosyl side chains), 1,1,1-kestose,
1,1-kestose, 1-kestose, inulin (beta(2Right arrow1)-linked fructans) and
sucrose at 60, 45, 39, 12, 9 and 3%, respectively, of the activity observed
for levan. Melezitose, raffinose and stachyose were not hydrolysed by
the enzyme. The fructan beta-fructosidase was inhibited by p-chloromercuribenzoate,
EDTA, Fe-2-+, Zn-2-+ and Co-2-+, whereas Mn-2-+ had no effect; effects
of Cu ions are also reported. The first 20 N-terminal amino acids was
sequenced. The enzyme had temp. and pH optima at 25 degree C and 5.5,
respectively. Concn. of up to 12% NaCl, had effect on enzyme activity.

TI: Chemical composition and microbiological changes during spontaneous
and starter culture fermentation of enam ne-setaakye, a west African fermented
AU: Asiedu-M; Sanni-AI
SO: European-Food-Research-and-Technology; 215 (1) 8-12, 24 ref.
AB: Enan ne-setaakye, a fermented fish-carbohydrate dish, was made from
minced fish flesh (75%), yam (20.5%), onions (1%), ginger (1%) and salt
(2.5%). The ingredients were mixed, and the mixture was divided into 2
portions which were rolled into 2-cm diam. balls. The balls were allowed
to ferment naturally for 120 h at ambient temp. (30 plus/minus 1 degree
C) or inoculated with starter and fermented for 72 h at 30 degree C. At
the end of fermentation, 113 isolates belonging to the genera Lactobacillus,
Pediococcus, Bacillus, Pseudomonas, Klebsiella, Staphylococcus, Debaromyces
and Candida were obtained from the naturally fermented product. L. brevis
and P. pentosaceus were the dominant species, with 24 and 19% occurrence
respectively, while Candida species occurred least (3%). Changes in viable
count of the microflora showed predominance of lactic acid bacteria from
48 h of fermentation (5.8 x 10-8 cfu/g) to the end (2.3 x 10-1-0 cfu/g).
Enterobacteriaceae, detected at 10-3 cfu/g at 0 h, were not detectable
after 72 h. Fungi were not isolated, while yeasts became detectable from
72 h, reaching 10-3 cfu/g at the end of fermentation. With a shorter fermentation
period of 72 h with a lactic acid bacteria count of 10-1-0 cfu/g, no detectable
Enterobacteriaceae or fungi and a yeast population of 10-3 cfu/g were
obtained when fermentation was carried out using L. brevis and P. pentosaceus
as starter cultures. A pH level of 4.3, 3.1% titratable acidity and 2.1
salt content were obtained in starter culture-fermented product. There
were significant differences in moisture and free fatty acid contents
of naturally and starter culture-fermented samples, but protein content
(16%) was not significantly different. Sensory evaluation showed consumer
preference for samples which had been steamed for 15 min.

TI: Chemical, microbiological, and sensory properties of fermented fish
products from Sardinella sp. in Nigeria.
AU: Achinewhu-SC; Oboh-CA
SO: Journal-of-Aquatic-Food-Product-Technology; 11 (2) 53-59, 14 ref.
AB: Composition and sensory properties of fermented sardinella (Sardinella
sp.) were investigated with a view to using it as a flavouring for soups
and stews and as a protein source in infant foods. Fresh sardinella were
subjected to `chance inoculation' (natural) fermentation with or without
treatment with spices at room temp. (30 plus/minus 2 degree C). Fermented
products were analysed for chemical and microbiological composition and
sensory properties. For unfermented and fermented products, moisture content
was 73 and 70%, fat content was 7 and 8% and crude protein content was
16 and 18%, respectively. Fermentation caused a slight decrease in trimethylamine
from 20 to 18 kg/100 g in unfermented and fermented products. Peroxide
value was 6 mEq/kg for fermented products and 8 mEq/kg for unfermented
products. A consistent decrease in pH from 6.5 to 4.3 and a corresponding
increase in titratable acidity from 0.69 to 1.84 NaOH/100 kg was observed
during fermentation. Fermentation caused a slight decrease in total viable
count of microorganisms, which ranged from 250 to 380 cfu/g for fermented
and unfermented products. Sensory evaluation showed that fish fermented
in 10% salt solution had significantly (P less than 0.05) higher scores
for flavour and overall acceptability than those for products fermented
in a 15% salt solution.

TI: Characteristics of fish sauce made from Pacific whiting and surimi
by-products during fermentation stage.
AU: Lopetcharat-K; Park-JW
SO: Journal-of-Food-Science; 67 (2) 511-516, 31 ref.
AB: Potential for making high quality fish sauce from Pacific whiting
and its by-products was studied. Fermentation conditions and physicochemical
transformations during fermentation were also investigated. The fermentation
conditions for producing Pacific whiting fish sauce were static atmospheric
fermentation with 25% salt at 50 degree C. The enzymes effective in fermentation
were heat stable and salt tolerant. Fermentation at 50 degree C gave higher
yields than at 35 degree C. Total nitrogen content of whole fish fermented
at 50 degree C reached levels equivalent to those of commercial fish sauce
before 15 days, supporting the strong degradation effects of Pacific whiting
enzymes at earlier stages. Levels of soluble solids and relative gravity
also reached those of the commercial sample at 60 days. However, colour
value of unripened fish sauce was far from that of commercial fish sauce,
indicating that ripening may be necessary to develop proper colour. Staphylococcus,
Bacillus and Micrococcus were the predominant microorganisms during fermentation.

TI: Application of multi-enzymic method in fermented fish sauce production
from Harengula zunasi's offal.
AU: Deng-Shanggui; Peng-Zhiyang; Yang-Ping; Xia-Xingzhou
SO: Food-&-Fermentation-Industries; 28 (2) 32-36, 8 ref.
AB: Fermented fish sauce was produced from the offal of Harengula zunasi,
using an enzymic method. The offal was treated with alkaline and neutral
proteinase, followed by flavorase. Optimal conditions included pH 7.0,
50 degree C, treatment with1.5% alkaline proteinase and 1.5% neutral proteinase
for 60 min, and treatment with 2.0% flavorase for 60 min. The fermented
fish sauce produced by this method has a total amino acid content of 40.3%.
Its content of amino acids making a positive contribution to flavour (including
Glu, Asp, Gly, Ala, Pro and Ser) is 49%. The sauce also contains 19 and
11 mg/g total and amino N, respectively.

TI: Fermentation and microflora of plaa-som, a Thai fermented fish product
prepared with different salt concentrations.
AU: Paludan-Muller-C; Madsen-M; Sophanodora-P; Gram-L; Moller-PL
SO: International-Journal-of-Food-Microbiology; 73 (1) 61-70, 33 ref.
AB: Effects during fermentation of plaa-som (a Thai fermented fish product
prepared from snakehead fish, salt, palm syrup, and sometimes toasted
rice) of NaCl concn. (6, 7, 9 and 11%) on pH decrease and microflora composition
were investigated. Also, phenotypic tests, ITS-PCR, carbohydrate fermentations
and 16S rRNA gene sequencing were used in the identification of the lactic
acid bacteria (LAB) and yeast present during plaa-som fermentation. Results
showed that a rapid pH decrease occurred in low-NaCl (6 and 7%) batches
of plaa-som (from pH 6 to 4.5), whereas a slow or no decrease in pH occurred
in high-NaCl (9 and 11%) batches. All batches, apart from the 11% NaCl
batch where microbial counts were 1-2 log lower, experienced increases
in counts of LAB (10-8-10-9 cfu/g) and yeasts (10-7-5 x 10-7 cfu/g). LAB
isolates were identified as Pediococcus pentosaceus, Lactobacillus alimentarius/farciminis,
Weisella confusa, Lb. plantarum and Lactocococcus garviae (only isolated
from high-NaCl batches), while 95% of the yeasts were identified as Zygosaccharomyces
rouxii. A NaCl level of 9% was observed to delay plaa-som fermentation
due to inhibition of LAB growth. It is proposed that Z. rouxii may contribute
positively to the flavour development of plaa-som, although its growth
had no influence on fermentation rate.

TI: Genotypic and phenotypic characterization of garlic-fermenting lactic
acid bacteria isolated from som-fak, a Thai low-salt fermented fish product.
AU: Paludan-Muller-C; Valyasevi-R; Huss-HH; Gram-L
SO: Journal-of-Applied-Microbiology; 92 (2) 307-314, 31 ref.
AB: Importance of garlic for fermentation of a Thai fish product (som-fak)
was established, and differentiation was made between garlic-/inulin-fermenting
lactic acid bacteria (LAB) at the strain level. Som-fak was prepared by
fermentation of a mixture of fish, salt, rice, sucrose and garlic. The
pH decreased to 4.5 after 2 days of fermentation; however, when garlic
was omitted from the mixture, acidification was lacking. LAB predominated,
and approx. one third of 234 isolated strains fermented garlic and inulin
(the carbohydrate reserve in garlic). These strains were identified as
Lactobacillus pentosus and L. plantarum. RAPD analysis revealed one major
RAPD type (29 strains) isolated from all stages of fermentation. It is
concluded that garlic is essential for acidification of som-fak, and that
garlic-fermenting strains constitute a significant, homogeneous part of
the LAB flora.

SO: Food-Australia; 53 (12) 546-549, 57 ref.
AB: Flavour properties, safety and physiological effects of monosodium
glutamate (MSG) are reviewed. Aspects considered include: the relationship
between glutamate contents of foods and umami flavour; occurrence of free
glutamate in natural foods (meat, poultry, sea foods, vegetables, cheese,
milk); glutamate levels in traditional processed foods (Marmite and other
conc. extracts, soy sauce, fermented fish products, fish sauce); changes
in glutamate concn. during ripening of fruits and cheese and maturation
of ham; contribution of glutamate to the flavour profiles of foods; safety
evaluation of MSG (Chinese Restaurant Syndrome, effects on brain function);
and the role of MSG in the promotion of healthy eating.

TI: Use of exogenous enzymes to elaborate the Roman fish sauce garum.
AU: Aquerreta-Y; Astiasaran-I; Bello-J
SO: Journal-of-the-Science-of-Food-and-Agriculture; 82 (1) 107-112, 48
AB: Underutilized by-products of the fishing industry were used in the
preparation of a fermented fish sauce with nutritional and sensory properties
similar to garum, a fish sauce consumed in ancient Rome. The raw materials
were frozen tuna (Tunnus thynnus) liver and eviscerated mackerel (Scomber
scombrus). Of the commercial enzyme preparations tested (Fungal Proteinase
P31000, Alcalase 2.4L, Kojizyme MG, Trypsin PTN 3.0 and Neutrase 0.5L)
Neutrase gave the greatest yield (ml liquid/100 g initial mixture) and
was used in all further experiments. Fermentation was carried out at 35-37
degree C, in the presence of 10% salt, 1 g/100 g oregano, coriander and
thyme, and 0.001 g/100 g BHA and BHT, for 48 h, followed by filtration
and dilution with a guar gum solution. The resulting sauce contained 21
mg/g N, 10% fat and 5.9% salt. Analysis of its fatty acid profile revealed
high levels of oleic, eicosapentaenoic and docosahexaenoic acids, at 15.1,
4.2 and 11.3 g/100 g fat, respectively, resulting in a high PUFA/saturated
fatty acid ratio (0.98) and a low omega-6/omega-3 ratio. In comparison,
traditional Korean fermented fish sauce (a type of nuoc mam) was found
to contain 0.06% fat and 16.8% salt, although its N content was similar
to that of garum.

AB: Occurrence of stereoisomers of the parent all-trans-configured triterpenoid
4,4'-diaponeurosporene in Gram positive bacteria which have importance
in food fermentation processes was investigated. 3 strains of Staphylococcus
carnosus obtained from fermented fish and Italian salami, Lactobacillus
plantarum LTH 4936 from bakers yeast, Enterococcus sulfureus DSM 6905-T
from vegetables and E. mundtii DSM 4838-T from soil produced the predominant
all trans-isomer and also 7 cis-isomers of 4,4'-diaponeurosporene. Results
revealed triterpenoid carotenoids in staphylococci and lactic acid bacteria,
which differ from those formed in S. aureus. Possible activities of 4,4'-diaponeurosporene
in bacteria are discussed.

AU: Kuda-T; Miyamoto-H; Sakajiri-M; Ando-K; Yano-T
SO: Nippon-Suisan-Gakkaishi; 67 (2) 296-301, 13 ref.
AB: 34 fermented fish in bran paste (nukazuke, salinity; 10-15%) products
made by 13 factories in Japan were analysed for microbial composition.
The predominant bacterial group was halophilic lactococci, however samples
obtained from different factories or different fish (including sardine,
Pacific herring, mackerel, puffer fish and yellowtail) showed wide variation
in numbers of these bacteria ( less than 10-2-10-7 cfu/g). The numbers
of halophilic or osmophilic yeasts ranged from less than 10-2 to 10-6
cfu/g. In 3 samples, aerobic cocci and yeasts were dominant rather than
lactococci. The main organic acid determined in products was lactic acid;
the lactic acid concn. also differed (0.1-1.7 g/100 g) between products
from different factories and fish. Volatile basic nitrogen (VBN) in nukazuke
products ranged from 50 to 230 mg/100 g.

TI: Changes in proximate composition and extractive components of rice-bran-fermented
mackerel heshiko during processing.
AU: Itou-K; Akahane-Y
SO: Nippon-Suisan-Gakkaishi; 66 (6) 1051-1058, 21 ref.
AB: Compositional changes occurring during processing of heshiko (a fermented
fish product made from mackerel) were studied. Heshiko was produced from
fresh mackerel by salting for one wk and subsequent pickling in rice-bran
mixture for 7 months. During the salting period, fish were strongly dehydrated
and decreased in body wt. by up to 12% due to salt penetration. During
this period, lipid was mostly retained in the fish, although a small amount
of protein was eluted. During fermentation in rice-bran mixture, sugars
permeated from rice-bran into the fish and ash and lipid levels in the
fish slightly decreased; protein levels did not vary during fermentation.
Throughout salting and fermentation, most free amino acids and peptides
increased markedly; however His levels showed a sharp decrease. The increase
in levels of Glu, Asp, Gly, Ala, Val, Ile, Leu, and low mol. peptides
suggested that these components might contribute to the characteristic
flavour of heshiko. Nucleotides, such as IMP decreased to trace amounts
at the early stage of fermentation. Organic acids such as lactic, acetic,
succinic, and malic acids increased markedly during fermentation, while
pH of fish flesh decreased from 6.6 to 5.2.

AB: Composition of 13 types of Southeast Asian salt-fermented fish sauce
(patis, nuocmam and nampla of various types) was evaluated. Fish used
included mackerel, silver pomfret and anchovy. Moisture averaged 60.6-72.8%,
ash 18.2-25.8%, crude protein 0.9-13.7% and volatile basic N compounds
14.1-338.6 mg/100 ml. pH values were 4.66-5.91 and salinity 24.1-30.6%;
values are also shown for total N, amino N, total free amino acids and
total ATP-related compounds. Sauces proved rich in free amino acids such
as glutamic acid, lysine, leucine, alanine, aspartic acid, valine and

TI: Partial characterization of lacticin NK24, a newly identified bacteriocin
of Lactococcus lactis NK24 isolated from Jeot-gal.
AU: Lee-NK; Paik-HD
SO: Food-Microbiology; 18 (1) 17-24, 23 ref.
AB: The bacteriocin lacticin NK24 produced by Lactococcus lactis NK24,
isolated from jeot-gal (a high-salt fermented fish product), was identified,
partially purified, and partially characterized. Results showed that lacticin
NK24 had a relatively broad spectrum of activity against most lactic acid
bacteria and several pathogens (including some Gram negative microorganisms).
However, lacticin NK24 had no inhibitory activity against a yeast and
fungi tested. Treatment with proteinase IX or proteinase XIV led to a
complete loss of bacteriocin activity, but no modification of activity
was observed when lacticin NK24 was treated with the other enzymes tested
(trypsin, proteinase XIII, alpha-chymotrypsin, papain, pepsin, proteinase
K, alpha-amylase and lipase). Lacticin NK24 proved to be relatively heat
stable; inhibitory activity was detected during 30 min heat treatment
at 100 degree C. Lacticin NK24 was stable at pH 2.0-9.0, and was unaffected
by a range of organic solvents (ethanol, methanol, acetone, toluene, isopropanol
and chloroform). The bacteriocin demonstrated a bactericidal mode of action
against Leuconostoc mesenteroides KCCM 11324. SDS-PAGE determined that
lacticin NK24 had an apparent molecular mass of approx. 3-3.5 kDa. It
is concluded that the characteristics of lacticin NK24 make it a potential
candidate for use as an antibacterial agent in foods for the control of
spoilage and pathogenic microorganisms.

SO: Journal-of-the-Korean-Fisheries-Society; 32 (6) 693-698, 18 ref.
AB: Changes in composition of salt-fermented fish sauce from northern
sand lance (Ammodytes personatus) during fermentation were investigated.
Compositional parameters were examined at 1-3 month intervals during 18
months fermentation. Moisture content decreased slightly, but the content
of VBN and crude protein, total N, amino N, degree of hydrolysis, and
absorbance at 453 nm increased gradually during fermentation; ash content,
pH, and salinity showed almost no change. The contents of total N, amino
N, and degree of hydrolysis increased sharply until 6-8 months fermentation
and then showed a gentle increment. Hypoxanthine and uric acid were the
most abundant ATP related compounds, ranging from 83.1% to 92.9%. After
18 months of fermentation, sauces contained high levels of free amino
acids such as glutamic acid, alanine, lysine, leucine, isoleucine, valine
and aspartic acid.

AB: Fifteen different commercial salt-fermented fish sauces (CNS) prepared
from northern sand lance (Ammodytes personatus) were evaluated for composition
and compared with a traditional-style fish sauce (TNS) prepared from the
same fish species. CNS sauces contained 66.5-71.0% moisture, 19.3-24.6%
ash, 4.7-12.0% crude protein, and the pH and salinity were 5.56-6.47,
24.0-32.9%, respectively. Total N, amino N, total free amino acids and
total ATP related compounds were in the ranges 0.781-1.918 g/100 ml, 445.9-1037.9
mg/100 ml, 3258-6562 mg/100 ml and 4.766-8.989 mumol/1 ml, respectively.
CNS had higher moisture content, TMAO, TMA and pH, but lower content of
crude protein, salinity, total N, amino N, total ATP related compounds,
absorbance at 453 nm and total free amino acid than TNS. Both CNS and
TNS samples were rich in free amino acids, such as glutamic acid, lysine,
alanine, leucine, valine, aspartic acid and isoleucine (descending order).

SO: International-Journal-of-Food-Microbiology; 57 (1/2) 129-133, 12 ref.
AB: Inhibitory effects of ingredients (cumin, coriander, mustard, wheat,
fennel seeds, black pepper and dried lemon) added during processing of
mehiawah (fermented fish sauce) on pathogens (Vibrio parahaemolyticus,
Staphylococcus aureus, Salmonella typhi and Escherichia coli) that may
be potential contaminants of the fish or process plant were investigated.
Samples of mehiawah were inoculated with pathogens at a level of 1.0 x
10-4 cfu/ml and stored at 25 degree C; pathogens were enumerated after
3, 7, 14 and 28 days of storage. Results showed that neither fennel nor
coriander affected survival of any of the pathogens. Individually, lemon
had the most inhibitory impact on E. coli making the organism undetectable
after 3 days, while in the presence of all ingredients E. coli was not
detectable after 7 days. Counts of S. aureus fell rapidly in all samples;
after 7 days S. aureus could only be detected in mehiawah with no added
ingredients. S. typhi survived for 28 days in mehiawah with no added ingredients
and in the presence of black pepper alone, but was eliminated within 3
days in samples with only lemon, mustard or cumin added, and within 14
days in samples with only wheat added. Mehiawah containing all ingredients
was free from S. typhi after 7 days. V. parahaemolyticus was eliminated
from samples after 7 days with individual additions of wheat, lemon or
mustard, however samples containing all the ingredients tested positive
for up to 21 days. Based on these results, it is concluded that mehiawah
poses minimal health risks to consumers due to the elimination of pathogens
by the ingredients in a matter of days.

TI: Biogenic amine formation and degradation by potential fish silage
AU: Enes-Dapkevicius-MLN; Nout-MJR; Rombouts-FM; Houben-JH; Wymenga-W
SO: International-Journal-of-Food-Microbiology; 57 (1/2) 107-114, 18 ref.
AB: Fish silage, produced by fermentation of fish paste by lactic acid
bacteria (LAB), contains a considerable amount of free amino acids that
can act as precursors for formation of toxic biogenic amines. Several
bacteria, including some LAB, have the capacity to degrade these biogenic
amines through the production of diamine oxidases (DAO; amine oxidases).
In this study, attempts were made to identify suitable LAB starter cultures
for production of safe fish silage. LAB isolates were screened for production
of biogenic amines (histamine, tyramine, cadaverine and putrescine), effect
of different conditions (pH 4.5 and 7.0, 15-37 degree C, and addition
of 12% sucrose, 2% NaCl and 0.05% cysteine) on degradation of histamine
in fish silage by DAO was assessed, and LAB isolates were tested for DAO
activity in MRS broth (containing 0.005 g/l histamine) and ensiled fish
slurry. Results showed that of 77 LAB cultures isolated from naturally
fermented fish pastes, 17% were capable of producing greater than or equal1
biogenic amines. Histamine degradation by DAO occurred at all temp., but
not at pH 4.5, and was unaffected by addition of 12% sucrose or 2% NaCl;
however, 0.05% cysteine caused a decrease. 5 out of a further 48 LAB cultures
isolated from naturally fermented fish pastes were capable of degrading
histamine in broth within 30 h by 20-56%. 2 of these isolates were also
capable of 50-54% histamine degradation in ensiled fish slurry. It is
concluded that the use of these 2 isolates in fish silage preparation
could potentially reduce the risks posed by histamine.

SO: European-Food-Research-and-Technology; 210 (4) 280-285, 15 ref.
AB: Previous studies have shown that fermentation of cold-smoked fish
with lactic acid bacteria (LAB) can be applied to produce storable, microbiologically
safe fish products. In this study, possible formation of biogenic amines
during the fish fermentation process was investigated; sensory quality,
pH, titrated acid content, wt. loss, aw value, redox potential and microbiological
counts during 0-7 days fermentation were also evaluated. 3 groups of fish
(rainbow trout) with 3 different LAB inocula and a group without any inoculum
were made. Fermentation of the products made with LAB was successful.
Products had acceptable sensory properties while inoculated LAB grew to
greater than 8 log cfu/g; pH of the products was reduced from 6.4 to 5.0-5.3
and aw was reduced from 0.980 to 0.927. Counts of Pseudomonads, which
were the predominant bacteria of fish raw material, were completely suppressed.
Fish raw material and fermented products contained low amounts of biogenic
amines with one exception: cadaverine, histamine and tyramine increased
in all product groups in one experimental series (II) out of 3. The highest
concn. of these amines were in the control products without any LAB inoculation
since the LAB used and the contaminants isolated from fermented products
were unable to produce cadaverine, histamine or tyramine, it is suggested
that appearance of biogenic amines in experimental series II may have
been caused by non-isolated contaminants of fish raw material.

sauce in the Gulf.
AU: Al-Jedah-JH; Ali-MZ; Robinson-RK
SO: Journal-of-Food-Science-and-Technology,-India; 36 (6) 561-564, 10
AB: Poor handling of raw fish at ambient temp. can easily lead to contamination
with pathogens like Salmonella, Listeria monocytogenes and Escherichia
coli; concern has been expressed that mehiawah, a spiced, fermented fish
sauce popular in the Gulf States (Middle East), could pose a health hazard
to consumers. An extensive examination of home-made and commercial samples
of mehiawah revealed that samples were free from vegetative pathogens
even after storage for several months at 20-25 degree C; Bacillus cereus
was identified in one sample. The inhibitory nature of the product was
confirmed, when fresh mehiawah was inoculated with Salmonella typhi, Staphylococcus
aureus, Vibrio parahaemolyticus and E. coli. Only V. parahaemolyticus
survived beyond 14 days and even this species could not be detected at
21 days. It is concluded that, during routine manufacture, the initial
processing of the fish eliminated any serious contamination, while the
combined effects of salt, acidity, spices and, perhaps fatty acids from
the fish oil, arrested the growth of any pathogens that might enter the
product during bottling.

AB: Physicochemical, microbiological and sensory changes occurring in
sikhae (traditional Korean fermented fish with cereals) produced from
Alaska pollack (Theragra chalcogramma) fermented at different temp. and
times were analysed to determine optimum conditions for value-added commercial
production. Alaska pollack, cooked cereals, pepper powder, sliced radish,
garlic, ginger and malt were mixed, packaged and fermented at 5, 15 and
25 degree C for up to 28 days. Samples were analysed for pH, total viable
cell count, contents of lactic acid, amino nitrogen (NH2-N) and volatile
basic N (VBN), TBA number and sensory qualities. Acidity decreased as
fermentation progressed at all temp., while contents of lactic acid, NH2-N,
and VBN increased. TBA number increased during fermentation at 5 degree
C over all fermentation periods, while at 15 and 25 degree C, TBA numbers
increased up to day 14 and then decreased. Numbers of total viable cells
increased up to days 21 and 14 at 15 and 25 degree C, respectively and
then decreased, while at 5 degree C numbers increased continuously over
all fermentation periods. It is concluded that Alaska pollack sikhae fermented
at 15 degree C for 21 days showed the most desirable sensory properties
and acceptable aftertaste with low odour; however reductions in salt concn.
and further hydrolysis of fish may be required to reduce its moderately
high saltiness and chewiness.

AB: Free D-amino acids were determined in 60 fermented fish sauces collected
from various outlets in Southeast and East Asia. Of the major D-amino
acids, D-alanine, D-aspartate and D-glutamate, D-alanine was the most
abundant and found in almost all fish sauces. Fish sauces from Myanmar
contained significantly higher amounts of these D-amino acids than those
from the other 6 countries investigated (Thailand, Vietnam, Laos, China,
South Korea and Japan). In fish sauces differing in fermentation periods,
D-alanine and D-aspartate were highest in fish sauces fermented 22 months.
Experiments were also conducted to investigate formation of D-amino acids
in fish sauces prepared in the laboratory from sardine (Sardinops melanostictus)
and squid (Todarodes pacificus) to which 10 or 20% NaCl was added; salted
homogenates were incubated at 30 degree C for 1 yr (20% salted samples)
or 6 months (10% salted samples) and analysed weekly for microbial counts
and monthly for D-amino acids. In 20%-salted sauces prepared from sardine
and squid, D-alanine increased slightly only in squid-based samples. In
10%-salted preparations, highest D-alanine increase and microbial counts
were observed in squid-based samples. This increase was largely suppressed
in sardine preparations. All other fermented fish products analysed also
contained D-alanine in widely varying amounts and a small amount of D-aspartate.
Data indicated that D-alanine could potentially be used as a molecular
marker of bacterial activity in fermented fish products of low salt concn.

AB: Forty-seven strains of homofermentative rod-shaped and 5 heterofermentative
cocci lactic acid bacteria were isolated from 4 kinds of fermented fish
(pla-ra, pla-chom, kung-chom and hoi-dong) in Thailand. Bacteria were
separated into 4 groups by phenotypic and chemotaxonomic characteristics,
including fluorometric DNA-DNA hybridization. 5 strains (Group I) contained
meso-diaminopimelic acid in the cell wall. 4 strains were identified as
Lactobacillus pentosus, and 1 strain was L. plantarum. Tested strains
of this group produced DL-lactic acid. The remaining rod-shaped bacteria
(23 strains (Group II) and 19 strains (Group III)), lacked meso-diaminopimelic
acid in the cell wall, produced L-lactic acid and were identified as L.
farciminis and Lactobacillus spp., respectively. The amount of cellular
fatty acids of C16:0 and C18:1, and the DNA base compositions were significant
for differentiating the strains in Groups II and III. Five strains of
cocci in chains (Group IV) produced gas from glucose and produced D-lactic
acid. They were identified as a Leuconostoc spp. The distribution of these
bacteria in fermented fish in Thailand is discussed.

volatile basic nitrogen, TBA and free amino acids, and degradation of
disodium 5'-inosinate and inosine. Squid viscera and koji, added at concn.

the high incidence of liver cancer in Thailand. The VNA concn. in greater
than 1800 fresh and preserved (dried, salted and fermented) Thai foods
and beer, collected between 1988 and 1996, were examined; nitrate and
nitrite concn. were also examined to investigate whether concn. were correlated
with those of VNA in foods. VNA levels were examined by GC-thermal energy
analysis. VNA were detected in pork sausages, fermented pork, ham, beef
(salted and dried), fermented fish, other fish products (including salted
and dried), and beer; VNA were not found in curry dishes, soups, fried
dishes, rice dishes or noodle dishes. 6 kinds of fermented fish (95 samples)
contained significant amounts of _1 VNA (N-nitrosodimethylamine (NDMA),
N-nitrosopyrrolidine (NPYR) and N-nitrosopiperidine). In salted or dried
fish, levels of NDMA ranged from trace amounts to levels as high as 66.5
mug/kg. NDMA and NPYR were detected in some fermented vegetable products
and high concn. were observed in some samples of fermented beans (Tau-chiau).
Concn. of VNA were not correlated with concn. of nitrates or nitrites
in Thai foods. Dietary intake data for 4 major regions (north, northeast,
central and south) of Thailand were used to estimate regional exposure
to dietary VNA. Dietary exposure to VNA was estimated to be highest in
north and northeastern Thailand. The possible role of dietary VNA exposure
in the aetiology of hepatocellular carcinoma (HCC) and cholangiocarcinoma
(CCA) is discussed. Regional differences in dietary VNA exposure may partially
explain the marked geographical differences in incidence of HCC and CCA
observed in Thailand.

2-12% ground boiled rice and 4% minced garlic (packed in banana leaves
and fermented for 2-5 days at 30 degree C), were examined, to determine
species required for fermentation. The significance of the garlic and
rice as substrates for fermentation was also evaluated. LAB isolated from
raw materials and som-fak at 0,1, 2, 4 and 5 days of fermentation were
characterized by phenotyping, and evaluated for ability to ferment starch,
garlic and inulin in model substrates. Fermentation of som-fak without
and with garlic was also examined. 185 LAB were identified and classified
according to origin and species. At the beginning of fermentation, Leuconostoc
spp., Lactobacillus curvatus and Lactobacillus lactis subsp. lactis dominated
the microflora, followed by more acid-tolerant Lactobacillus species,
such as L. curvatus, L. casei, L. pentosus and L. plantarum, the latter
dominating towards the end of fermentation. Fermenting properties of strains
were generally associated with the main carbohydrate substrate of their
origin - starch fermenters originated from rice and garlic/inulin fermenters
from garlic and banana leaves. Minced fish contained both types. In som-fak,
a succession of garlic-fermenting L. plantarum strains was identified,
suggesting that garlic may be a more important carbohydrate source than
rice starch during fermentation. Initial presence and growth of LAB able
to ferment garlic proved essential for rapid reduction of pH. Thus, garlic
may have a dual role, by inhibiting Gram-negative bacteria and yeasts
and providing a fermentation substrate.

of a single polar or bipolar tuft flagellum, had a large cell size, formed
coccoid bodies, were microaerophilic and had quinone type Q-8. The DNA
G+C content of the strains was 44-45 mol%. Data revealed that the strains
represent a new species of halophilic helical bacteria. The sequence of
the 16S rRNA gene of strain H7-T, designated the type strain of the new
isolates, and all of the Oceanospirillum spp., except for O. linum, were

HPLC columns, and with detection by a photolysis-pyrolysis-thermal energy
analyser. A strong chromatographic peak at retention time 12 or 4.5 min,
the same as that for N-(nitrosomethyl)urea (NMU), was obtained on PRP-1
or C18 HPLC columns from the fish sauce sample with 10mM trifluoroacetic
acid as the basic mobile; acetonitrile, as organic modifier after the
sample was nitrosated by 5 mmol/l of sodium nitrite (final concn.) at
37 degree C and pH 2.0 for 1 h. No response above retention time could
be observed from the nitrosated sample in the detection system without
photolysis. Such a peak could not be obtained from the unnitrosated fish
sauce either. These results indicated that the component was NMU. Furthermore,
this component, NMU, could also be detected in the nitrosated human gastric
juice sample spiked with fish sauce. The formation of NMU in the sample
was pH- and nitrite-dependent. This paper provides direct evidence that
NMU formation could occur in fish sauce from the high-risk area for stomach
cancer and in the fish sauce spiked human gastric juice during nitrosation
under simulated gastric conditions.

AB: Fermentation of foods is often caused by lactic acid bacteria and
it is possible that they exert an antibacterial effect which is relevant
in both product safety and inhibition of pathogens in situ. Lactic acid
bacteria (isolated from Thai fermented fish products) which showed anti-listerial
activity were characterized, with particular reference to inhibition of
pathogens and spoilage bacteria. Growth characteristics were also determined
in order to assess their suitability for use as starters and/or biopreservatives.
Of the 44 strains examined, 43 inhibited L. monocytogenes. All strains
were inhibitory to Vibrio cholerae and V. parahaemolyticus and 37 inhibited
Aeromonas spp. Identification of isolates showed that the majority (29;
65%) were Lactobacillus spp.; Lactococcus lactis subsp. lactic and Carnobacterium
piscicola were also isolated. Rice (which is added to fish products and
serves as a carbohydrate source), potatoes and corn starch were only fermented
by 4 isolates, indicating that other bacterial species may be responsible
for the rapid fermentation of products. Results of growth profiles indicated
that isolates were unsuitable for use as live biopreservatives in chilled
products. It is concluded that lactic acid bacteria with a broad inhibitory
spectrum are not uncommon in Thai fermented fish products and are likely
to contribute to their safety and stability.

AB: Kimchi is composed of many ingredients such as Chinese cabbage, garlic,
ginger, red pepper and fermented fish extract; some of them are known
to have antioxidative activities due to their scavenging effect against
reactive oxygen species (ROS). To study the health effects of kimchi on
human skin cells, keratinocytes (A431, epidermal carcinoma, human) and
fibroblasts (CCD-986SK, normal control, human) were cultured under oxidative
stress conditions provoked by paraquat, a superoxide anion generator,
and H2O2 in the absence and presence of kimchi extract. Survival rate
of the keratinocytes was greatly reduced when they were exposed to concn.
of H2O2 of greater than 1mM, but cytotoxicity of H2O2 on cells was significantly
reduced by kimchi extracts. Kimchi fermented for 2 wk remarkably decreased
the cytotoxicity generated by H2O2 in keratinocytes. Paraquat concn. greater
than 1mM showed strong keratinocyte toxicity, and the extracts from kimchi
fermented for 1, 2 and 3 wk showed protective effects in that order. Fibroblasts
were significantly affected by H2O2, as were keratinocytes. Although almost
all extracts from kimchi fermented for different periods showed protective
effects against cell death when 0.5mM concn. of H2O2 were employed, extracts
from kimchies fermented for 2 wk showed the strongest protective effect
on fibroblasts treated with 1mM H2O2 for either 1 or 4 days. Most of the
kimchi extracts showed weak preventive effects or no effect at all on
oxidative stress produced by paraquat. In conclusion, extracts from kimchi
fermented for 2 wk seem to have the greatest potential in protecting skin
cells from oxidative damage; this might be related to the scavenging effects
of kimchi components produced during the fermentation process. [From En

affected product manufacture on a large scale. In this review, salt fermented
anchovy was used to elucidate the properties of the microorganisms involved
in its fermentation, in order to determine areas in which product quality

assay. The higher the heating temp. and the longer the heating time, the
more the mutagenicity caused by both terasi and its starter; the highest
mutagenic activity was achieved by heating at 100 degree C for 60 min.
Terasi starter has stronger mutagenic properties than terasi. Indonesian
jasmine tea (yellow tea) was examined for its antimutagenic properties
against mutagenic terasi. Tea components present in fraction C (water
soluble, chloroform and ethyl acetate insoluble fraction) as well as in
fraction D (water soluble, chloroform, ethyl acetate and n-butanol insoluble

foods [including acid-leavened bread and pancakes, acid-fermented cereal
gruel, and beverages, acid-fermented starches, acid-fermented vegetables
and acid-fermented fish and newt]. In particular, the beneficial effects
of lactic fermentation of food are considered by focusing on 2 examples
taken from Korean cuisine, kimchi and sikhae. Sikhae is the generic name
of a class of Korean lactic acid fermented fish products that contain
6-8% salt and generally are at pH 4-5. Koreans are able to preserve fish
for 1-2 months at ambient temperatures by this method. Due to the low
salt content, sikhae contributes much-needed protein to the Korean rice-based
diet. Kimchi is the generic name for a class of Korean lactic acid fermented
vegetables that contain 3-4% salt and generally are at pH 4.0-4.5. Kimchi
is an important source of vitamins and minerals especilly during the wintertime.
It is a popular dish and provides a source of intestinal lactic acid bacteria.
The physiological effects of kimchi have been studied widely in Korea
and recent results are summarized in this paper.

AU: Surono-IS; Hosono-A
SO: Milchwissenschaft-; 51 (9) 493-497, 30 ref.
AB: Previous studies have shown that lactic acid bacteria isolated from
dadih, a traditional Indonesian fermented milk of Indonesia, are able
to bind mutagens and inhibit mutagenic nitrosamines. The antimutagenicity
of milk cultured with lactic acid bacteria from dadih against terasi,
an Indonesian fermented fish/shrimp product shown to be mutagenic using
the Ames test, was investigated. Milks were inoculated with 1 each of
24 lactic acid bacteria isolated from dadih and incubated for up to 24
h at either 30 or 37 degree C depending on the species. Growth parameters
of the bacteria and antimutagenicity against terasi extracts were determined.
Generally, all milks cultured with dadih lactic acid bacteria displayed
antimutagenic activity towards terasi extract although wide variation
was observed. Highest antimutagenicity was displayed by milk cultured
with Lactobacillus casei subsp. casei R-52, which showed 96.93% inhibition,
while lowest antimutagenicity (29.39% inhibition) was observed for milk
cultured with Lactococcus lactis subsp. lactis R-63. Results suggest that
the fermented milk product suppresses mutagenesis in a desmutagenic manner.
Bacterial strains with the greatest antimutagenic properties also had
highest viable counts during incubation. Since terasi is widely consumed
in Indonesia, it is suggested that consumption of dadih will be beneficial.

AU: Sun-Choung-Ahn; Gui-Ju-Lee

AB: Effects of fermented sea food sauces (shrimp and anchovy) and chitosan
on the composition and texture of kimchies were investigated. During fermentation,
pH of kimchies prepared with shrimp and anchovy sauces decreased; addition
of chitosan gave an increase in acidity. Addition of sauces or chitosan
resulted in a decrease in the compression force of kimchies; the decrease
was greater for kimchies prepared using sea food sauces than with those
made with chitosan. During fermentation, hot water soluble pectin levels
in control kimchies (without chitosan or sea food sauces), and kimchies
made with sea food sauces increased, while HCl soluble pectin levels decreased;
the opposite was observed in kimchies containing chitosan. Kimchies made
with chitosan had higher hardness, crispness and chewiness values than
the other kimchies. Results showed that pH and acidity and compression
force were highly correlated with crispness. It is concluded that addition
of chitosan to kimchies influences pectic substance levels and improves
their textural properties. [From En summ. & tables.]

Quality of salts used in the curing procedures, i.e. crude solar salt
and refined salt, which has lower moisture and microbial load than crude
salt were determined. Japanese mackerel (Trachurus japonicus) were used
as raw materials. Salt was added to fish at 150 g/kg and fermentation
was conducted at 26 degree C. Samples were stored for 60 days at 60% RH.
Samples were analysed during fermentation and after 2 wk, and 1 and 2
months of storage. Differences after fermentation and storage of both
refined-salted and crude-salted fish were as follows: decrease in aw of
fish during processing was slower with crude salt than with refined salt;
volatile basic N and total microbiological counts were higher in crude-salted
fish; and the polyamine of highest concn. in crude-salted samples was
histamine, whilst cadaverine concn. dominated in fish fermented with refined
salt. TBA reactive substances and peroxide values of the extracted total
lipids increased during processing and free fatty acid and diglyceride
concn. were higher in the crude-salted fish than in the samples cured
with refined salt. Polyenoic fatty acid levels were higher in samples
fermented with refined salt; levels of total cholesterol oxides were higher
in crude-salted samples. It is concluded that use of refined salt is to
be preferred over the use of crude salt, as it leads to a better quality
product. [From En summ.]

for the development of special kimchi for the children. 1100 children
in 2nd, 4th and 6th grade from public and private elementary school participated

students prefer processed food, especially animal food, to kimchi. The
spicy flavour of kimchi was the most popular reason for dislike of kimchi,
and also the most important reason for those who liked kimchi. Chinese
cabbage kimchi was found to be the most favourite kimchi followed by kakdugi

AB: Nine strains of lactic acid bacteria that hydrolyse starch were isolated
from burong isda, an indigenous (Philippines) fermented food made from
fish and rice. Conventional taxonomic and DNA-DNA reassociation studies
indicated that all isolates were Lactobacillus plantarum. Each isolate
harboured greater than 10 plasmid species with molecular sizes of 2 to
60 kb. Amylolytic amylase activity of one of the isolates, L137, was lost
by treatment with novobiocin (frequency 43%) which was concomitant with
curing of a 33-kb plasmid designated pLTK13. It is suggested that pLTK13
carries a gene necessary for the synthesis of an amylolytic enzyme. An
acidophilic starch-hydrolysing enzyme secreted from L137 cells was purified
46-fold (specific activity of 44 U/mg protein). The enzyme had a molecular
mass of approx. 230 kDa; optimum temp. and pH for the enzyme reaction
with soluble starch were 35 degree C and 3.8-4.0, repectively. The enzyme
hydrolysed soluble starch, amylopectin, glycogen and pullulan and, to
a lesser extent, amylose; it exerted no activity on dextran and cyclodextrins.
Major reaction products from soluble starch were maltotriose, maltotetraose
and maltopentaose; panose was not detected and maltotriose was the sole
product from pullulan. Km values for soluble starch, pullulan and amylose
were 4.0, 5.1 and 33 g/l, respectively. Results suggest that this enzyme

AU: Adler-Nissen-J; Demain-AL
SO: Journal-of-Industrial-Microbiology; 13 (6) 335-343, 21 ref.
AB: Controlled aeration of Leuconostoc mesenteroides [isolated from a
Korean fermented fish product] was studied as a possible mechanism for
control of the formation of acetic acid, a metabolite of major influence
on the taste of lactic fermented foods. Fermentations were carried out
in small scale in a medium in which growth was limited by the buffer capacity
only. Ethanol and acetic acid formed during the fermentation were analysed
by rapid head-space GC, and the ratio of the molar concn. of these 2 volatiles
quantitatively predicted the balance between the formation of acetic acid
and lactic acid. O2 concn. during the fermentation decreased rapidly to
zero, indicating that O2 transfer was limited by the volumetric O2 transfer
rate (k1aC-*). A linear correlation between k1aC-* and the quantity of
acetic acid produced was established. It is suggested that such oxygenated
heterolactic fermentation processes should be analysed as fed-batch fermentations
with O2 as the limiting substrate. Addition of fructose in limited amounts
resulted in the formation of 0.5 mol of acetic acid for each mole of fructose,
thus offering an alternative mechanism for controlling acetic acid formation.

AB: Changes in the composition of certain chemical components during processing
of hatahata-zushi, a Japanese fermented product of sandfish and boiled
rice, were investigated. The pH, and moisture and salt contents of the
finished product were 4.1, and 552 and 41.0 g kg---1, respectively, on
a salt-free dry wt. basis. Concn. of polyamines except histamine increased
gradually during fermentation. Contents of free amino acid, especially
glutamic acid, alanine, valine, and leucine, increased during fermentation.
Lactic acid and acetic acid contents increased markedly during fermentation.
Total lipid content of the raw sample was relatively high (385 g kg---1
dry wt. basis). During soaking in water, content of phosphatidylethanolamine
(PE) and phosphatidylcholine (PC) markedly decreased, while that of free
fatty acids increased. The decreases in PE and PC continued up to the
end of fermentation. The triglyceride content decreased to a large extent
during the early stages of fermentation and remained almost unchanged
thereafter. Lipid deterioration of hatahata-zushi seemed to be due mainly
to hydrolysis of lipids by endogeneous and/or exogenous lipolytic enzyme

and flavour of the fish sauces. However, after several exposures, the
difference in aroma became significantly smaller, but flavour remained
almost unchanged. Groups A and B (familiar with aerobically fermented
fish sauce) preferred the aroma of the aerobic over that of the anaerobic
sauce but accepted the flavour of the anaerobic sauce. Group D, who had
never known or heard of either of the sauces, had a reverse reaction and
preferred the anaerobic over that of the aerobic sauce. Group C (Filipino
children) did not like the sauces. In general, fermentation under anaerobic
conditions brought changes in the aroma quality of fish sauce during the
manufacturing process, to yield an acceptable product.

various proportions (100:0, 50:50, and 0:100) on acceleration of fish
sauce fermentation using herring as raw material [was investigated]. Results
showed that supplementation with trypsin and chymotrypsin significantly
increased protein hydrolysis (P less than 0.05). Fish sauces prepared
from herring with enzyme supplementation contained significantly more
total N, soluble protein, free amino acids and total amino acids compared
to fish sauce with no added enzyme (P less than 0.05). Supplementation
with trypsin and/or chymotrypsin mixture produced the most favourable
results in terms of protein hydrolysis; there was no difference among
enzyme treated sauces in terms of free amino acid composition. [Except
for] amino acid profile, accelerated fermented fish sauce product had
similar chemical and microbiological composition to Nampla, a first grade
commercially produced Thai fish sauce. Sensory analysis of products for
colour, flavour and aroma indicated that panellists preferred the lighter
coloured fish sauce prepared with enzyme supplementation compared to the
darker coloured commercially produced Nampla. However, there was no significant
preference (P less than 0.05) for aroma and flavour of the enzyme supplemented
sauce or Nampla. Results of this study indicate that acceptable fish sauce
can be produced from herring; addition of enzymes has the potential to
reduce fermentation time to approx. 2 months without compromising product

sardine sauces prepared using the different salt and temp. regimes are
discussed. Fish sauce prepared with 20% NaCl had the highest content of
amino and total N; other parameters were not markedly affected by NaCl
content. Fermentation at the higher temp. reduced the fermentation period
to 5-6 months; fish fermented at 22 degree C still had an after taste
after 6 months. Sardine sauces were regarded as having a more pleasant

AB: Momoni is a Ghanaian fermented fish product used as a condiment for
flavouring soups and stews and also as the main protein in a meal. Effects
of traditional processing methods on composition of the lipids, free amino
acids and organic acids of momoni made using Japanese jack mackerel (Trachurus
japonicus) were investigated. Moisture content decreased from 751 to 505
g kg---1 after fermentation for 3 days, and then remained almost constant
during storage. Changes in pH were minimal, although a gradual decrease
was observed from 6.2 to 5.9 after 2 months of storage. Salt accumulation
due to salting increased up to 325 g kg---1 but remained almost unchanged
during storage. Volatile basic nitrogen (VBN) increased to 0.8 g kg---1
on a salt-free DM basis, after 2 months storage. Most free amino acids,
except histidine, which was present in the highest concn. in the samples,
increased during processing and subsequent storage. However, no detectable
amount of histamine was formed after 2 months of storage. Lactic acid,
the most prominent organic acid (3.12 g kg---1 salt-free DM) in the raw
materials, decreased during processing and storage. Diphosphatidylglycerol,
free fatty acids and lysophosphatidylcholine increased. Processing resulted
in depletion of sphingomyelin, phosphatidylserine and phosphatidylinositol
with decreases in triglycerides, cholesterol, phosphatidylethanolamine
and phosphatidylcholine. Proportion of the extracted total lipids present
as polyunsaturated fatty acids decreased; this was accompanied by increases
in the proportions of saturated fatty acids, indicating a high degree
of oxidation. Peroxide value and TBA value increased on fermentation,
confirming the observed oxidation, but decreased during storage. Although
oxidation was extensive, following hygienic and good manufacturing practices,
this method could prevent spoilage taking place in fish if good-quality
raw materials are used. [From En summ.]

included: fish (anchovy, mackerel, tuna, tilapia); meat; vegetables (amaranth
leaves, cassava, okra, cocoyam, beans, plantains, peppers, sweet pototoes);
cereals (cornflour, sorghum, rice, corn grits, corn dough, wheat flour
dough); nuts (peanuts); and prepared foods (smoked fish, fermented kapok
seeds, porridge, palmnut soup, stews). Legumes, meat, fresh fish and smoked
fish contained highest levels of minerals. Peanuts and bean-cakes had
highest levels of NSP, while legumes and cereals (especially unfermented
or unrefined cereals) contained highest phytate levels. Variability in
Zn and Ca contents of similar soups and stews was due to differences in
proportions of ingredients used in preparation. Addition of peanuts, fermented
locust bean seeds and fermented kapok seeds increased minerals content
of soups and stews. It was suggested that fermentation of foods be promoted
to maximize hydrolysis of phytic acid in cereal products, staple foods
in African countries.

AB: Analyses of the microflora of burong bangus, a traditional fermented
fish [Chanos chanos] and rice product of the Philippines, revealed that
a sequential type of fermentation with overlapping growth takes place.
Streptococcus initiated the fermentation process and generally persisted
up to the latter part of the fermentation. Pediococcus appeared next,
but comprised only a small % of the microflora. Both Leuconostoc and Lactobacillus
appeared on the 3rd day and were generally present up to the end of the
fermentation, with Lactobacillus predominating among the microflora in
the final days. In the course of characterizing the lactic acid bacteria
involved in the fermenting rice-fish mixture, some isolates were found
to be capable of hydrolysing starch. These were revealed to be Gram-positive,
rod-shaped and catalase negative. Tentative identification of one of the
isolates, L137, showed that this strain possesses very similar characteristics
to those of Lactobacillus plantarum and Lactobacillus coryniformis subsp.
coryniformis. The % G + C of L137 was 45.2 while those of L. plantarum
and L. coryniformis subsp. coryniformis are 45.1 and 45.0, resp. However,

no sour or sweet substances in contrast to the soy products; however,
both products were salty and contained amino acids. No major differences
were found in the umami (good tasting) amino acids which were found among
the fish sauces. Glutamic acid, closely related to umami substances, was
found to be a relatively stable amino acid which did not suffer from any
secondary decomposition during fermentation.

is given [covering fat emulsions, cheese, meat and fish, fermented and
pickled vegetables, tomato products, semi-dried fruit, fruit juices and
fruit syrups, fruit preserves, drinks, bakery goods and sugar confectionery].
Some fields of application are discussed that are either unimportant or
not permitted in the UK. Because of their physiological inertness, their
effectiveness even in the weakly acid pH range and their neutral taste,
sorbic acid and its salts (the most commonly used products are sorbic
acid itself (E200) and potassium sorbate (E202)) and have become leading
preservatives in the food sector throughout the world over the past 30
yr. In many countries sodium sorbate (E201) and calcium sorbate (E203)
are also permitted. Sorbic acid is sparingly soluble in water, sodium
sorbate has better solubility, and potassium sorbate is very freely soluble
and can be used to produce 50% stock solutions [which remain stable for
some time]. Sodium sorbate in solid forms is unstable and very rapidly
undergoes oxidation in exposure to atmospheric O2, and is therefore not
produced on industrial scale. Calcium sorbate is used in the manufacture
of fungistatic wrapper because it is highly stable to oxidation, but this
use is very limited. Sorbic acid and sorbates can be directly added into
the product. Products can be dipped or sprayed with aqueous solutions
of sorbates. Dusting of food with dry sorbic acid is also possible but
less recommended because sorbic acid irritates the skin and mucous membranes.

fish sauce). Preparation methods for the 4 foods are outlined; both sauces
are prepared from Indian oil sardine with the addition of spices. Results
of the analyses are tabulated. They included the following. Tareeh contained
more protein, ash, Ca, Na, Mg, P and Zn than mehiawah but less moisture,
fat, carbohydrate, Fe and K. Cheese bread contained more protein, fat,
ash, Ca, P and Na than date bread but less Fe, K, Mg, Cu and Zn. The amino
acid profiles of the fish sauces were superior to those of the breads.
Particular attention is drawn to the high Na contents of the fish sauces.

preserved fish-glucose substrates.
AU: Adams-MR; Cooke-RD; Twiddy-DR
SO: International-Journal-of-Food-Science-&-Technology; 22 (2) 105-114,
AB: Lactic fermented fish products are common in S. E. Asia. The composition
and quality of the products vary considerably, since they are usually
produced on a small scale and the fermentation of the fish-salt-carbohydrate
mixtures depends on the natural microflora. A minced fish-salt-glucose
system was used to evaluate the factors that favour a rapid lactic fermentation.
Studies with Lactobacillus plantarum and Pediococcus pentosaceus indicated
that fermentation rates increased in the range 0-5% w/w of glucose or
sucrose, whereas increasing the salt concn. from, 0 to 6% slowed the rate
of pH decrease. 1% salt and 4% glucose were used for subsequent studies.
The nature of the gas atm during incubation had little effect on fermentation
rate, and chemical modification of the initial substrate pH with lactic,
acetic or citric acid did not assist lactic fermentation. Incubation temp.
of 15, 24, 30 and 37 degree C were evaluated: the lactic acid bacterial
count rarely exceeded the total spoiler count by greater than 10x during
the first 2 days (although it subsequently increased). Consequently reduction
of the pH to less than 4.5 within the first 2 days was difficult to achieve.
The use of cooked fish minces gave only slight changes in the fermentation

was modified into a large scale process, producing an extruded kishk snack.
Adaptation of tempeh production to domestic conditions is described, the
raw material being Austrian field beans (instead of the traditional soybeans).
The tempeh produced was preferred to soybean tempeh in trials. However,
as the product is consumed fresh (traditionally within 24 h) and has low
shelf-life further trials are currently in progress to make a storage-stable
tempeh, e.g. using sterilization, or to use tempeh as a food flavour enhancer.

AB: In an attempt to improve processing and reduce blow-fly infestation,
a 1-ton prototype solar dome dryer was constructed and tested. Several
drying trials were carried out using 5 different fish spp. Performance
of the dryer was compared with sun drying on traditional, flat chicken
wire and sloping chicken wire racks. The solar dome did not perform as
well as expected. Very similar drying rates were obtained for sun and
solar dome drying. The poor performance was attributed to the nature of
the raw material (i.e. fermented fish) used to prepare guedja (the local
dried product), and the weather. Blow-fly infestation was a problem if
sufficient care was not taken to prevent entry of flies into the dryer.
Low initial temp. had to be used in the dome to avoid cooking the fragile
raw material, so that improved drying rates could not be achieved. These
temp. were too low to kill either the adult blow-flies or larvae. [See

AB: The role of yeasts in determining the flavour and quality of burong
isda, a fermented fish food [see preceding abstr.] was investigated by
isolation from samples of red burong isda made with 5 different fish spp.
Viable yeast counts were 10-6-10-8/g and culture yielded 484 isolates
which were divided into 24 groups on the basis of physiological and morphological
characters. Dominant yeasts in all isolates were Saccharomyces cerevisiae,
Candida tropicalis, C. parapsilosis, Torulopsis mogii, Pichia vini and
P. strasburgensis. T. mogii and P. vini were found only in burong made
with Tilapia nilotica, probably due to the higher salt content of this
burong (5.4% vs. 1.8-2.1% for other samples). It is concluded that the
yeast flora arises due to chance contamination and that the variations
are responsible for differences in flavour from product to product.

Today, however, fermentation is applied only because of the specific and
unique organoleptic qualities induced by this process. The final products
are highly priced delicacies, often with a small and geographically very
limited market. 2 types of fermented fish products, 'gravad fisk' and
'kryddersild', are widely accepted in all Scandinavia. Both products are
manufactured industrially using fatty fish as raw material and by adding
salt, sugar and spices to either the fillet or the whole (uneviscerated)
fish. The products vary greatly in salt content, 'gravad fish' having
a rather low (9% NaCl) and 'kryddersild' a higher content (around 21%
NaCl) in the water phase during maturation. Manufacture, maturation, storage
life, spoilage and possible health hazards of the 2 products are discussed
and some future prospects for fish fermentation are briefly considered.

act as replacement for NaCl generally used in fish sauce fermentation.

TI: [Bacteriology of fermented fish.]
AU: Kandji-P; Conway-J
SO: FAO-Fisheries-Report; No. 268 (Suppl.), 84-93, 8 ref.
AB: The microbial flora of 'guedj' (dried fermented fish produced in Senegal)
was studied from the fresh fish to the finished product. Tabulated data
show the bacteriological quality of sea water, freshly landed fish, and
guedj from artisanal production, as well as the lactic flora. The main
organisms on fresh fish were mesophilic, psychrotropic and acidophilic
aerobes (10-7, 10-6 and 10-6/g resp.), replaced during fermentation by
lactic bacteria, chiefly Lactobacillus plantarum. Total count on artisanal
guedj was 10 000/g with no coliforms, salmonella or pathogenic staphylococci,
and less than 10/g of faecal streptococci and sulphite-reducing clostridia.
When produced under a solar tent, a hard crust is formed on the outside
of the fish which reduces permeability and gas exchange between fish muscle
and the atm. This creates anaerobic conditions and decomposition of the
flesh, as well as changes in flavour. [See FSTA (1983) 15 11R741.]

AU: McIver-RC; Brooks-RI; Reineccius-GA
SO: Journal-of-Agricultural-and-Food-Chemistry; 30 (6) 1017-1020, 16 ref.
AB: Volatile flavour components were studied in commercial Nam-pla, a
Thai sauce made from fermenting salted fish for 6-12 months. The sauce
was adjusted to pH 2.0 and extracted with diethyl ether to obtain an aqueous
layer and an ether layer; the basic fraction was obtained from the aqueous
layer and the neutral and acidic fractions were obtained from the other
layer by pH adjustment and further ether extraction. Each fraction was
examined by GLC on a Carbowax 20M column, and by GLC-MS. Eight acids and
1 lactone constituted 96% of the acidic fraction. The acidic fraction
possessed a sharp, cheesy aroma. The neutral fraction possessed a meaty
aroma and contained 3 lactones as main components, as well as alcohols
and heterocyclic compounds; the only aldehyde identified was benzaldehyde.
The aroma of the basic fraction was dominated by ammonia and trimethylamine,
which, together with dimethylamine and 2,3-butanediol, constituted the
major components. In total, 43 compounds were identified that have not
previously been reported as constituents of fish sauce, including 8 acids,
10 alcohols, 6 amines, 7 other N-containing compounds, 4 lactones, 3 carbonyls
and 5 S-containing compounds. [See FSTA (1983) 15 7A403.]

AB: Some aspects of indigenous fermented foods, many of which are almost
unknown outside the Orient, are reviewed, with special attention given
to the microorganisms and their role in the fermentation process. The
indigenous fermented foods are reviewed according to the microorganisms
involved in the process. The best known foods fermented by moulds are
tempe (from soybeans), oncom (from peanut presscake) and angkak (from
rice). Foods fermented by bacteria include fermented vegetable products,
fermented fish products (sauces and pastes), fermented seeds (natto und
thua-nao from soybeans, dage from oil-rich seeds), fermented starch-rich
raw materials (e.g. banku, kenkey, akpler, ogi and agidi from fermented
maize, idli, dosa, appam and puto from rice, and gari from cassava), and
fermented plant juice (palm wine, and pulque from agave). Foods fermented
by a mixture of moulds and yeasts, e.g. using ragi inoculum, include fermented
rice, brem (confectionery), rice wine, and tape-ketella (from cassava).
Foods firstly fermented by moulds, followed by a fermentation with a mixture
of bacteria and yeasts, include soy sauce (shoyu) and other fermented
soybean products, e.g. miso, taoco, hamanatto, and tou-chih. Specific
aspects of fermented foods, i.e. mould spp., lactic acid bacteria, yeasts
and salt, are also discussed. [See FSTA (1983) 15 3G155.]

SO: Annals-of-the-New-York-Academy-of-Sciences; 378, 123-136, 20 ref.
AB: Previous reports on the antithiamin activity (ATA) of various polyphenolic
compounds in plants and of thiaminase in raw fish led to a study of the
effect of local foods containing ATA on the thiamin status of local Thai
people. In northern Thailand, fermented tea leaves are chewed continuously
as a stimulant, tea drinking is common, the diet contains large amounts
of glutinous rice, raw fermented fish, and vegetables, and betel nut chewing
is common. These foods were collected and assayed for ATA, and experiments
were carried out with human volunteers to study the effects of these foods
on thiamin status, as determined by thiamin pyrophosphate effect (TPPE);
results are shown in tables, histograms etc. It is said that 1 g dry tea
leaves brewed in 100 ml boiling water for 5 min destroyed 0.21 mg thiamin/h,
fermented tea leaves (daily intake approx. 12 g) destroyed 0.93 mg thiamin
per g wet wt./h, extract from betel nut chew (average intake 21 g/day)
destroyed 0.83 mg thiamin per g wet wt./h, and thiaminase activity of
raw fermented fish (consumption approx. 50 g/day) was estimated to contain
4.5 units/g. The data obtained suggest that antithiamin factors in foods
could be a precipitating factor in causing thiamin deficiency in humans.
However cooking will inactivate thiaminase, and high TPPE resulting from
consumption of polyphenols such as tannins could possibly be prevented
by delay in the consumption of these compounds after meals or consuming
foods high in ascorbic acid along with the meals.

AU: Areekul-S; Thearawibul-R; Chantachum-Y; Viravan-C
SO: Journal-of-the-National-Research-Council-of-Thailand; 11 (1) 1-11,
AB: Vitamin B12 contents were determined in some Thai foods, including
fish sauce, soy sauce and fermented fish, and in serum of patients with
infectious hepatitis, hookworm, amoebic liver abscess, opisthorchis and
malaria infection. The results were compared with those of normal subjects.
The absorption of vitamin B12 was also determined in some patients, using
-5-8Co vitamin B12. The results showed that some patients in the present
studies had lower serum vitamin B12 levels and lower absorption of this
vitamin than those of the normal subjects. However, they did not show
any signs or symptoms of vitamin B12 deficiency. This could be due to
the findings that the normal Thai diets, including fish sauce and fermented
fish, contained a considerable amount of vitamin B12 and the stored vitamin
B12 in the liver could last for 3-4 yr.

AB: Production of a fish hydrolysate, using plant proteases, which could
be added to traditionally fermented fish sauce to increase the total vol.
without affecting the overall nutritional quality was investigated. Effect
of adding bromelain, papain or ficin, on the rate of hydrolysis and the
extent of the conversion of insoluble fish protein, to soluble N was examined.
The conditions employed were similar to those used in traditional fish
sauce manufacture but both whole and minced Ikanbilis (Stolephorus sp.)
were investigated. Measurement of the extent of hydrolysis after 1, 2,
4, 7, 14, 27, 28 and 35 days at 33 degree C showed that bromelain tended
to give slightly better results with some 65% of the protein being hydrolysed.
The effect of temp., enzyme, co-enzyme and salt concn. for hydrolysis
by bromelain were investigated and the optimum conditions established
at the pH normally found in fish sauce production. The hydrolysate produced
in 18-21 days was comparable to traditional fish sauce in distribution
and concn. of N compounds and had very little aroma. The product could
be added to traditional sauce without affecting its quality. [See preceding

manufacture. II. The use of acids at ambient temperature.
AU: Beddows-CG; Ardeshir-AG
SO: Journal-of-Food-Technology; 14 (6) 613-623, 10 ref.
AB: When batches of Ikanbilis were acidified using HCl to pH 2.0-3.5 at
30 degree C, rate and extent of hydrolysis of the fish protein and rate
of formation of supernatant liquor were increased. Effect of pH and salt
concn. was investigated. Although the presence of salt generally decreased
extent of proteolysis, it made the mixtures easier to filter. The optimum
conditions were either pH 2.0 and 10% salt (w/w) or pH 3.0 and 15% salt
(w/w). The extent of fish protein hydrolysed was comparable to the natural
fermentation and concn. and distribution of soluble N were very similar
to those obtained in the traditionally produced sauces. This liquor was
produced within 6 days. The natural fermentation takes 4-9 months. Use
of formic acid was investigated and showed no particular advantage. When
the pH of the acid ensiled mixtures was adjusted above 4.2, calcium phosphate
precipitated; this was removed by filtration. Effect of adding alkaline
ensiled fish to acid ensiled fish mixtures (the pH of which had been re-adjusted)
was investigated. The amount of insoluble protein hydrolysed increased
to a limited extent. As the solutions produced by acid ensilation had
very little aroma or taste but had a high soluble N content, they could
be used to add to traditionally prepared fish sauce in order to increase
the net vol. which would increase the rate of production. [See following
abstr. for part I.]

AU: Beddows-CG; Ardeshir-AG; Johari-bin-Daud-W
SO: Journal-of-the-Science-of-Food-and-Agriculture; 30 (11) 1097-1103,
AB: Production of budu, a Malaysian fermented fish sauce was investigated
using laboratory-scale fermentation using frozen fresh fish (Stolephorus
sp.) and on a commercial scale using fish that had been stored several
h at greater than 30 degree C (ambient temp.). Fish or fish macerate was
salted and incubated in a humid atm at 30 degree C for 200 days. Max.
vol. of supernatant liquor was produced at 140 days; residue was chiefly
bone and scales. N solubilization increased with time to a max. of 56%
at 200 days; most was complete at 120-130 days. Inclusion of the antibiotic
rifampicin showed that the process was independent of any bacteria in
the fish. Peptide bonds continued to be hydrolysed in the liquor in the
140-200 day period when liquor vol. did not increase. Supernatant liquor
became brown after 60 days and subsequently darkened. Small-scale and
commercial processes produced similar (except for volatile acid content)
sauces with a cheesy aroma. The final sauce had a pH of 5.6, was saturated
with NaCl, contained 1.77% organic N and 0.12% volatile N. 66% of organic
N was as amino acids; 75% of volatile N was NH3, the remainder was mainly
trimethylamine. Commercially produced budu contained volatile fatty acids,
which were present probably as a result of bacterial action prior to salting
of fish. Final commercial sauce contained (mg/cm-3) ethanoic 2.1, propanoic
0.12, and n-butanoic acid 0.23. Concn. of the latter 2 acids did not increase
during fermentation; concn. of ethanoic acid increased from 1.29 mg/cm-3
initially to a max. of 2.15 after 156 days.

AB: A total of 6 brands of commercial fermented fish paste, representing
anchovy, shrimp, prawn and oyster products, was studied for amine content.
An ether extract of the paste was treated with trifluoroacetic anhydride
to form the N-trifluoroacetyl derivatives of the amines which were analysed
by GLC using a column packed with Supelcoport 100/200 mesh coated with
3% SP-2100 using flame ionization detection. Each product showed 7-17
peaks on the chromatograph. 9 amines were tentatively identified on the
basis of their retention times, and concn. of these 9 in the 6 products
are tabulated, together with concn. of histamine determined by fluorometry.
Amines found, in order of highest max. concn., were histamine (64 mg/100
g), 2-phenylethylamine (60 mg/100 g), tyramine (37), dopamine (30), tryptamine
(16), ethanolamine (10), octopamine (5), 2-mercaptoethylamine (3.5), cadaverine
(3.5) and 2-methylbutylamine (1.3). There were wide variations in concn.
of individual amines between pastes, and only histamine was found in all
products. Fermented prawn paste had the highest concn. of total amines
(227.6 mg/100 g) and fermented oyster paste the lowest (16.3 mg/100 g).

Neutral and basic fractions were isolated by direct solvent extraction

column effluent and sniffing components as they eluted from the column.
Methylamine, dimethylamine, trimethylamine, 2-methyl pyrazine, 2,5-dimethyl
pyrazine, hydroxyvaleric acid lactone and phenol have been identified
to date. Lactones quantitatively dominated the flavour profiles, accounting

AU: Beddows-CG; Ismail-M; Steinkraus-KH
SO: Journal-of-Food-Technology; 11 (4) 379-388, 14 ref.
AB: A fish hydrolysate was produced from homogenized mackerel using bromelain
to increase the rate and extent of proteolysis. Measurement of the extent
of hydrolysis and conversion of insoluble to soluble N compounds after
1, 2, 3, 5 and 14 days of incubation at 38 degree C showed that a hydrolysate
having some of the characteristics of an oriental fish sauce could be
formed from mackerel within this period with a net protein conversion
rate of over 75%, but it was necessary to include a 24 h incubation period
prior to the addition of salt. The technique was used for the investigation
of the causative agents of aroma production in the mackerel homogenate.
Assuming that the proteolysis was still carried out by the protease, the
mackerel homogenate was subjected to heat treatment, or mixed with antibiotics,
or TCA prior to addition of bromelain. These treatments caused the loss
of some of the constituents (associated with oriental fish sauce aroma)
which suggests that with mackerel, micro-organisms play a significant
role in aroma development. The method could be used for the investigation
of sauces prepared from oriental fish; as the causative agents of aroma
production might well be different. The bacteria involved with mackerel
could easily produce harmful products which were not investigated.

AB: The aroma of fermented fish sauce comprises 3 distinct notes, cheesy,
meaty and ammoniacal. Analysis showed that the cheesy odour was produced
by lower fatty acids and the ammoniacal odour by ammonia and amines. The
meaty aroma was much more complicated and was not analysed, but it was
shown that it could be produced by atmospheric oxidation of precursors
that were still present in mature sauces. Individual fatty acids were
determined in sauce at various stages of fermentation and an hypothesis
explaining the origin of the acids is deduced from the results.

TI: [Fermented fish products and botulism.]
SO: Norsk-Veterinaertidsskrift; 86 (7/8) 350-353, 31 ref.
AB: After a brief description of various fermented fish products (the
Norwegion 'rakefisk' and 'boknafisk' and the Japanese 'izushi', 'biribosni'
and 'kombaki') with special reference to their implication in outbreaks
of botutism, the manufacture of rakefisk is discussed on the basis of
literature data. Aspects considered include quantities of salt required,
maturation and storage temp., and the relative importance of microbial
and autolytic fermentation. It is suggested that maturation and storage
at temp. less than2 degree C is desirable, to prevent growth and toxin
production by Clostridium botulinum.

TI: A new product from Stavrida.
AU: Heikal-HA; El-Dashlouty-MS
SO: Agricultural-Research-Review; 50 (4) 229-233, 5 ref.
AB: A study was made of the production of a new salted, fermented fish
product, similar to 'Fesikh' in taste and flavour, but using the cheap
fish Stavrida rather than the usual Bori. The fish are left for 24 h in
the shade and as soon as the fish body is swollen dry salting is carried
out, the product is then left to ferment for 6-9 days. It was concluded
that Fesikh prepared using Stavrida was similar to the traditional Fesikh
in texture and flavour, and was cheaper to produce and gave a higher yield
than when using Bori. The slighly lower water holding capacity of Fesikh
prepared from Stavrida resulted in it having a slightly longer storage
life than the traditional product.

AU: Tjaberg-TB; Ystgaard-OM; Skulberg-A

AB: Rakefisk is a fermented fish product, which is made by salting fish,
generally trout or salmonoid-type, and allowing it to ferment naturally.
This type of product, which is eaten without heating, had given rise to
a number of cases of botulism in Norway. In experiments carried out to
determine the effect of fermentation temp. on Cl. botulinum type E (Fredriksberk),
trout in a brine containing 6% NaCl were infected with 1 x 10-6 spores/g
and fermented at temp. between -2 degree and +25 degree C. No toxin
was produced at less than4 degree C, which is therefore recommended as
the fermentation temp. for production of rakefisk.

AB: Two preparations of burong dalag, a fermented fish and rice food of
the Filipinos, were examined microbiologically and chemically. The lactic
acid fermentation was accomplished by Leuconostoc mesenteroides, Pediococcus
cerevisiae, and Lactobacillus plantarum, although strains of Streptococcus
faecalis and micrococci were also present in the first few days. The pH
was lowered to less than 4.0, and approximate equal to0-9% lactic acid
was attained in 1 wk. Careful sealing of the surface of the fermentation
mixture (79.5% moisture), was necessary to prevent growth of moulds and

by silage fermentation.
SO: Lantbrukshoegskolans-Annaler; 34 (6) 551-689, Numerous ref.
AB: The following investigations were made in studying development of
Clostridium botulinum type E (i) in fish silage: production of pure spores
in trypticase-peptone-glucose medium; effect of fish silage on enumeration
methods and assay of (i) toxin; enumeration of (i) and toxin analysis
in freshly made and fermented fish silage inoculated with (i). Sporulation
of (i) was 40-60%. Counts of (i) were slightly affected by inclusion of
fish silage in suphite-polymyxin-sulphadiazene agar. Inocula of (i) were
destroyed during fermentation if added at the ensiling stage, while (i)
added to fermented silage remained viable after 40 days' incubation. Silage
was toxic when inoculated with greater than 10-6 pure spores/g of silage.
Lactobacillus brevis and Streptococcus faecalis were amongst the organisms
interacting with (i) in fish silage. Determinations were made of degree
and development of fat rancidity in moist and air-dried silage. Fat rancidity
did not occur in moist silage, but drying in air at 50 degree C produced
a rancid smell.
