This study was designed to investigate fatty acid composition of salt-fermented seafoods in Chonnam area. The seven samples were analyzed for fatty acid composition. The contents of lipid was highest in salt-fer-mented anchovies and followed by salt-fermented small mullets, salt-fermented oysters, salt-fermented sea-arrows and salt-fermented small shrimps. The ratio of fatty acid composition depended on the samples but the major fatty acids were $C_{l6:0}$, $C_{20:5}$, $C_{l6:1}$, $C_{22:6}$, and $C_{l8:1}$ among all samples. The composition of n-3 polyunsaturated fatty acids was highest in salt-fermented sea-arrows (39.11%) and followed by salt-fermented small shrimps, salt-fermented oysters, salt-fermented anchovies and salt-fermented small mullets. In n-3 polyunsaturated fatty acids, $C_{20:5}$ was relatively abundant in salt-fermented oysters (17.71%) and salt-fermented sea-arrows (16.38%), and $C_{22:6}$ in salt-fermented sea-arrows (22.22%) and salt-fermented small shrimps (15.13~21.50%). However, $C_{22:6}$ was very little in salt-fermented small mullets.l mullets.

The historical background of fish fermentation in Asia and other regions of the world is reviewed. The classification of fermented fish products in different regions is attempted with respect to the technology involved. The fermented fish products are largely divided into three groups; (1) high-salt, (2) low-salt, and (3) non-salt fermented. High-salt fermented products contain over 20％ of salt and are represented by fish sauce, cured fish and fish paste. Low-salt fermented products contain 6-18％ salt and are subdivided into lactic fermented products with added carbohydrate and acid pickling associated with low temperature. Non-salt fermented products are represented by the solid state bonito fermentation and some alkaline fermentation of flat fishes. The local names of the products in different regions are compared and classified accordingly. The microbial and biochemical changes during fish fermentation are considered in relation to the quality of the products, and their wholesomeness is reviewed.

This study was conducted to understand the quality characteristics of salt fermented anchovies with heat treatment by measuring their chemical compositions. The heat-treated and non-heat treated salt fermented anchovies contained, respectively, 63.21 and 66.51% of moisture, 2.24 and 2.12% of total nitrogen (TN), and 1,537 and 1,520 mg/100 g of amino nitrogen (AN). In addition, heat-treated and non-heat-treated salt fermented anchovies contained 127 and 134 mg/100 g of volatile basic nitrogen (VBN), respectively. Moreover, measured the microbial level of heat-treated and non-heat-treated salt fermented anchovies was $2.58{\times}10^4$ and $3.61{\times}10^2$ CFU/mL, respectively. Also, the heat-treated and non-heat-treated salt fermented anchovies 3.65 and 0.30 units of protease activities, respectively. The total free amino acid contents in heat-treated and non-heat-treated salt fermented anchovies was 4,964 and 6,638 mg/100 g, respectively. The major free amino acid were glutamic acid, leucine, lysine, alanine, valine, isoleucine. Our results provide the characteristics of salt fermented anchovies and encourage their application for the food industry and cooking.

Salt-fermented fish and fish sauce are very important materials to make Kimchi. They provide good taste and plenty of nutrition to Kimchi during fermentation. However, it is difficult to purchase Korean salt-fermented fish or fish sauce out of Korea. Therefore, to generalize Kimchi for other countries, this research carefully compared the quality differences between Kimchi made with South East Asian fish sauce, which is fairly similar to traditional Korean salt-fermented anchovy extract (Aekjeot) in terms of taste and ingredients, and that made with traditional Korean salt-fermented anchovy extract. To determine quality differences among traditional Korean Kimchies made with different sauces, Korean-made salt-fermented shrimp, salt-fermented shrimp extract, salt-fermented anchovy and salt-fermented anchovy extract were used. Of the four Kimchis, the one made with salt-fermented anchovy extract was chosen as a control sample and compared with those made with three different South-East Asian fish sauces. In the sensory evaluation for acceptance of fish sauces, characteristics of taste, texture and overall acceptance showed significant differences. In the sensory evaluation for differences, characteristics of fish odor and crunchiness showed visible differences. For umami taste, all fish sauces received higher points than Korean salt-fermented anchovy extract (control sample), although the difference was not significant. Sensory evaluation and research results show that Kimchi can become a highly likable food overseas and Kimchi can substitute easily bought South-East Asian fish sauces for Korean salt-fermented fish sauces (Jeotkal).

Three kinds of salt-fermented Mytilus Edulis were produced: a Mytilus edulis seasoning sauce salt-fermented with Lactobacillus Plantarum CHO55, a Mytilus edulis seasoning sauce salt-fermented with Lactobacillus Plantarum CHO55 with teriyaki sauce added; and a A1ytilus edulis seasoning sauce salt-fermented with Lactobacillus Plantarum CHO55 with plum added. The salt-fermented Mytilus edulis with teriyaki sauce was high in crude protein (11.44%), and the plum seasoning sauce was more or less high in crude fat. Among the amino acids of the ingredients, glutamic acid was the most abundant in all the samples. The sauce with the highest total amino acid content of 9,169.48 mg per 100 g was the salt-fermented Mytilus edulis that was fermented with Lactobacillus Plantarum CHO55. Among the major fatty acids, C16:0 (palmitic acid), which is the main constituent of saturated fatty acid, was the most abundant; and the salt-fermented Mytilus edulis seasoning sauce that was fermented with Lactobacillus Plantarum CHO55 with plum added had a slight high amount of C18:2 (linoleic acid). The sensory evaluation showed the following sauces receiving the highest scores in all the measurement items, in this order, though the difference in their scores was not statistically significant: the salt-fermented seasoning sauce with plum added and the salt-fermented seasoning sauce with teriyaki sauce added.

Squid ink was added to the low salt fermented squid by 4% of concentration and ripened at 10$^{\cric}C$ for 6 weeks and at 20$^{\cric}C$ for 28 days. The effect of the squid ink on the non-volatile organic acids of low salt fermented squid were investigated. The results are as follows; The non-volatile organic acid in the salt fermented squid without addition of the squid ink was examined and the result showed that lactic and acetic acids were the major organic acids even if very small amount of citric and oxalic acids were detected. In the squid ink added to the low salt fermented squid, total quantity of non-volatile organic acid in the latter part of the ripening was lower than no treatment groups.

The microbial changes during the fermentation of salted and fermented shrimp at different salt levels $(3{\sim}30%)$ were investigated to elucidate the effect of salt on the microflora of the fermented shrimp. During 22 weeks of fermentation, the numbers of total bacteria and yeasts of the fermented shrimp with 3, 8, 30% salt generally decreased with fermentation time, while those in the fermented shrimp of 18% salt increased. Halophilic bacteria were found only in the late stage of the fermentation at 18% salt. The greatest number of the halophilic yeasts was observed also at 18% salt level. The results indicated that 18% salt provided the most favorable environment for the microorganisms related to the shrimp fermentation.

In this study, we determined the content of chitooligosaccharides (COS) in Korean commercial salt-fermented shrimps by competitive direct enzyme-linked immunosorbent assays (cdELISAs), using anti-COS mixture (COSM) antibody and COSM horseradish peroxidase (HRP) conjugate. When COS6 was spiked into salt-fermented shrimps at the level of $10-300\mu{g/g,}$ the average recovery was $120\pm19%$ ($mean\pmS.D.$). The COS contents of the 92 samples of Korean commercial salt-fermented shrimps collected during February 2000 and August 2002 were $36.3\pm20.7\mug$ COS6 equivalent/g (expressed as "$\mug/g$" hereafter). Among the samples, the COS contents of yuk-jeot ( $40.3 \pm 22.5 \mug/g, n=27$) and buksaewoojeot ($40.2 \pm 21.6 \mug/g, n=5$) were higher than the others. The COS contents of salt-fermented shrimps produced at Gwangcheon ($47.1 \pm 20.7 \mug/g, n=18$) and Gomso ($44.1 \pm 21.8 \mug/g, n=6$) areas were higher than those produced at the other areas. This is the first report to determine COS of salt-fermented shrimps by cdELISA.
