  • To produce low salt fermented anchovy by an accelerated method with Asp. oryzae and Bacillus sp. koji and change of physicochemical properties in the fermentation during 60 days were examined. The contents of moisture, crude protein, ash and salinity of salted anchovy changed little during the fermentation with 62.5~63.8%, 12.0~14.1%, 12.8~13.8%, and 12.8~13.8%, respectively. but crude lipid decreased from 15.5~15.8% initially to 13.1~13.9% finally. The p during the fermentation decreased slowly until day 50 and increased afterwards. Acidity increased remarkably on day 10 and changed little afterwards. This increase in acidity was particularly observed in the use of Asp. oryzae koji. Amino nitrogen contents sharply increased until day 20 wit 686.0~756.0mg% and then increased slowly. Ammonia nitrogen contents in the use of koji increased until day 40 or 50 and decreased after that ; while those without koji steadily increased until day 60. The TBA values for all the samples reached the highest point on day from 20 to 30 and decreased afterwards. The TBA values and ammonia nitrogen contents were higher in Bacillus sp. koji than in Asp. oryzae koji. The alcohol contents of anchovy paste a little decreased during 10 days, increased slowly after that until day 50, and then decreased. The content of alcohol was higher in the use of koji than in the non koji.

The results were as follows; 1) Most housewives learned the method of making the Kimchi from their mothers. Method was as follows; First, scatter salt on the whole Chinese cabbage and soak that for 3∼6 hours. After, wash the whole Chinese cabbage 3 times. Then, add red pepper powder, garlic, ginger and salted fermented anchovy as basic seasoning. Be sure to, mix the red pepper powder and salted fermented anchovy until they taste hot and salty. Store the whole Chinese cabbage until they ferment. Afterwards store the whole Chinese cabbage in the refrigerator. 2) It was the whole Chinese cabbage Kimchi that most family members preferred. 3) Among the family members, the old age group preferred newly made Kimchi because of the cool and fresh taste. The adult group preferred fresh taste, also smell and peculiar taste of the seasoning were important. The adolescent group preferred fresh taste and sour taste. 4) It shows that most of the family likes Kimchi, and among the family members, about 25% of the sons and daughters dislike Kimchi. And it shows that all family members dislike salty taste. 5) The older housewives’ Kimchi was preferred over the younger housewives’ Kimchi.

  • Volatile compounds in fermented ascidians Halocynthia roretzi were analyzed to identify key flavor compounds using SPME/GC/MSD (solid phase microextraction/gas chromatography/mass selective detector) after 60 days of fermentation at 5℃. The control was chopped ascidians subject to anti-browning and 4% salt treatment. product A was made from product C by adding an alcohol extract of red peppers and onion peel, 0.1% of glucose, and 0.55% of mixed amino acids (MAA; 0.05% Glu, 0.1% Pro, 0.3% Ala, and 0.1% Gly). After blanching and anti-browning treatment of chopped ascidians, Product B1 was made by adding 3% anchovy sauce and 6% sorbitol. Product B2 was made by adding 0.1% glucose and 0.55% MAA to Product B1. In total, 78 compounds were identified, including 31 alcohols, 15 aldehydes, and 10 ketones. The alcohols included 12 compounds from the C8-C10 series with floral and fruit odors, including octanol, 3-methyloctanol, 2,6-dimethyl-1-heptanol, (E)-5-octen-1-ol, 6-methyloctanol, (E)-3-octen-1-ol, (E)-3-decen-1-ol, (Z)-1,5-octadien-3-ol, and nonanol. These were detected in high amounts in ascidians and all fermented products. Aldehydes (octanal, (E)-2-octenal, 2,4-heptadienal, and nonanal) and ketones (1-oten-3-one and 2-heptanone) with fatty and mushroom odors were detected as major compounds, whereas nine ethyl esters were detected only in product A.

  • This study conducted to investigate the quality of commercial fish sauce and determine the grade of them by measuring the chemical compositions and biogenic amines. The commercial salt-fermented anchovy sauce contained 65.84-70.94% (mean : 68.39%) of moisture, 22.19-25.43% (24.22%) of salinity, 5.4-6.1 (5.8) of pH, 0.76-1.61%(1.18%) of total nitrogen, 478.52-924.66 mg/100 g (702.05 mg/100 g) of amino nitrogen and 584.59-1593.52 mg/kg of histamine. Whereas commercial salted-fermented sand lance sauces contained 66.63-71.99% (68.73%) of moisture, 23.9-25.5% (24.57%) of salinity, 5.5-6.4(6.16) of pH, 0.64-1.46% (1.07%) of total nitrogen, 433.51-1006.67 mg/100 g (665.36 mg/100 g) of amino nitrogen and 194.01-1839.68 mg/kg of histamine. Correlation of TN, AN and VBN containing nitrogen was high, but there was no significant correlation between these results and histamine. In total nitrogen content, 6 of the 20 fish sauces were less than Korea Food Standard. The eight samples were less than the amino nitrogen regulation of Korean Industrial Standard (KS). And 14 fish sauce were exceeded by 68% for moisture content standard of Korean Industrial Standard.

  • We investigated the changes of chemical compositions during fermentation of salted anchovy by salting methods for the purpose of establishment of processing condition. Dehydration of anchovy meat occurred remarkably by dry salting compared with that by brine salting and salinity was higher in anchovy by brine salting than by dry salting. Dehydration and salinity were increased in more anchovy fermented at $20^{\circ}C$ than at $5^{\circ}C$. Total nitrogen content was lower in anchovy by brine salting than by dry salting. Amino nitrogen increased remarkably during fermentation of salted anchovy at $20^{\circ}C$, while increased slightly at$5^{\circ}C$. Amino nitrogen showed maximum value on 120 days in dry salting and on 30 days in brine salting at $20^{\circ}C$, respectively. The changes of VBN were similar to the changes of amino nitrogen. The brine salting accelerated hydrolysis of anchovy meat compared with that of dry salting at $20^{\circ}C$, and the hydrolysis were suppressed at $5^{\circ}C$, The POV increased rapidly in dry-salted anchovy than brine-salted anchovy. We suggested that the appropriate processing condition of salted anchovy is to ferment for 5-6 months at $5^{\circ}C$ by addition of $25\%$ salt after pre-salting of raw anchovy.

  • The quality characteristics of the Korean traditional salt-fermented fish sauces, the traditional anchovy sauce (TAS) and the sandlance sauce(TKS) were evaluated comparing to the commercial anchovy sauce (CAS) and sandlance sauce (CKS). The acidity was higher in TKS than in TAS, whereas the contents of VBN, total-N and amino-N were higher levels in TAS. In color values, L and b values in TAS were generally higher than those in TKS, whereas a and ${\Delta}E$ values were higher in TKS. The contents of total free amino acids in TAS and TKS were $12.40\;g\%$ (w/v) and $9.549 g\%$ (w/v), respectively. The contents or six amino acids, alanine, glutamic acid, leucine, isoleucine, valine and Iysine were higher in TAS, whereas the contents of arginine, glutamic acid, leucine, alanine and valine were higher in TKS. Nucleotides such as IMP and hypoxanthine were principal components in both TAS and TKS. The nitrogen related compounds, TMAO, TMA and total creatinine were determined to be $108.8\;mg\%$ (w/v), $60.5\;mg\%$ (w/v), $62.4\;mg\%$ (w/v) in TAS, and those in TKS were $60.1\;mg\%$ (w/v), $24.1\;mg\%$ (w/v), $67.6\;mg\%$ (w/v), respectively.

  • Anchor Engraulis japonica was fermented with $10\%$ and $20\%$ salt at $10^{\circ}C$ ($10\%$ 5A) and $20^{\circ}C$ ($20\%$ SA), respectively, and the changes in lipid content, fatty acid composition and lipid oxidation was observed for 105 days. Peroxide value (POV) in $10\%$ SA reached to the maximum (46.4 meq/kg) on 30 days of fermentation, while in $20\%$ SA, it reached the maximum (54.7 meq/kg) on 45 days of fermentation, and then decreased in both samples during fermentation. Thiobarbituric acid values revealed a similar tendency with the change of POV during the fermentation. These results indicated that lipid of the anchovy was oxidized faster in lower salt than high salt in the early stage. Total lipid (TL) content during the fermentation for 105 days decreased approximately $16\%$ in $10\%$ SA and approximately $33\%$ in $20\%$ SA. Phospholipid (PL) content also decreased in both samples and the content of neutral lipid (NL) was unchanged in $10\%$ SA, while it decreased in the same amount as PL in $20\%$ SA. The prominent fatty acids in TL of the anchovy sample were 14 : 0, 16 : 0, 16 : In-7, 18 : in-9, 20 5n-3 and 22 : 6n-3. After fermentation for 105 days, approximately $87\%$ and $67\%$ of the prominent fatty acids remained in $10\%$ SA and $20\%$ SA, respectively, but the kind of the fatty acids was unchanged.

  • Fermented foods available in Korea may be classified into four groups, namely, fermented soybean products, fermented cereal products, fermented vegetable products, and fermented fishery products based on raw materials used. The representative fermented foods based on soybean are Kanjang(soysauce), Doenjang(fermented soybean pastes), and Kochujang(red pepper added-fermented soybean paste). Such fermented products are made using Meju(functioning as a starter and prepared by fermentation of steamed soybean mash) as an essential ingredient, and used widely as a soup base and/or in seasoning side-dishes for everyday meals year around. Excepting Sikhae, all fermented products based on rice and other cereal grains are of alcoholic nature. Takju (Makgeolli) used to be made using rice as the major raw material, however, mainly due to the shortage of rice in recent years, other cereals, such as, barely, corn, and wheat flours are also used to replace rice today. Owing to such changes in the raw materials. the popularity of Takju has been somewhat reduced, yet it is still widely consumed in rural areas. Although Chungju is a popular rice wine with superior qualify over Takju, the amount consumed is considerably limited. The highest qualify rice wine, Bupju, in particular, is made by a low temperature fermentation using glutinous rice. Kimchi is an unique fermented vegetable product of long tradition in Korea. Although it was for consumption mainly in winter season serving as a source of vitamins, today it is widely used throughout the year. Except Kkakdugi and Dongchimi, all of the fermented vegetable products contain salted Korean cabbage as an essential item, while they abound in varieties depending on material composition and methods of processing, and also on seasons and localities Next to Kimchi in this category is Kkakdugi made of raddish in popularity and quantity consumed. The four groups of fermented food products described above are reviewed in some detail and evaluated in terms of their nutritional significances, processes and microorganisms involved. and their commercial potentials. Jeotkal (or Jeot) is a name given to all fermented products of fishery origin. A number of Jeot can be prepared by adding salt and allowing fermentation to the raw materials such as shrimp, anchovy octopus, clam, oyster, etc.

  • Fish sauce is one of the most popular fermented fish products over the world. But it is usually manufactured with high salt concentration (>25%) and long periods of elaboration. In order to increase the consumption of fish sauce, the functional anchovy sauces with low salt concentrations (14 and 17%) were manufactured by adding sea tangle (Kjellamaniealla crassifolia), ume (Prunus mume Sieb. et Zucc), tochukaso (Paecilomyces japonica), and chitosan. On 50 days of storage, pH of all treatments decreased to 5.1, while the amount of lactic acid increased continuously as storage period increased. The amounts of VBN, amino-N, and TBA were highest on 50 days of storage and then kept constantly or decreased a little thereafter. The numbers of total viable cell, lactic acid bacteria, proteolytic bacteria, and fungi increased very slowly as storage period increased.

  • To investigate difference of components changes in salt-fermented anchovy, Engaulis japonicus sauce during 18 months fermentation by tank size, various chemical properties were examined at 2$\~$3 months intervals. The contents of total and amino nitrogen, total ATP related compounds increased gradually during 18 months of fermentation, and showed higher content in salt-fermented anchor sauce produced by large tank scale (LTS) product than those of small tank scale (STS) product during fermentation. Hypoxanthine and uric acid were the most abundant in ATP related compounds, ranging from $81.1\%$ to $90.4\%$, The cross point of inosine (HxR) + hypoxanthine (Hx) and uric acid was faster in LTS with 10.3 months fermentation than in STS with 12.6 months fermentation. After 18month of fermentation, the LTS was rich in free amino acids, such as glutamic acid, alanine, aspartic acid, valine, Iysine in that order. On the other hand, the STS was rich in free amino acids, glutamic acid, aspartic acid, alanine, vsine, valine in that order. Absorbance at 453 nm were higher in STS than in STS, but was no difference the rate of increase during fermentation.
