Sik-hae is a traditional and well-liked salt-fermented seafood with a low salt concentration in Korea. However, it is challenging to find data on market degradation. This study was conducted to investigate sensual characteristics, such as taste, odor and color, of 10 types of commercial Sik-haes [flounder (5 type), Alaska pollock (2 type), black edged sculpin, anchovy, and sandfish] as basic data for developing new products. The salinities of the commercial Sik-haes were significantly difference in the range of 3.0-6.7%. The pH and total acidity of 10 types of commercial Sik-haes were 4.45-5.24 and 0.84-1.46 g/100 g, respectively. The amino acid nitrogen and free amino acid contents, and total taste value were 72.0-333.0 mg/100 g, 425.6-1,726.4 mg/100 g and 17.0-115.9, respectively. According to the taste value, the major taste-related amino acids were aspartic acid and glutamic acid. Volatile basic nitrogen content and Hunter redness value of commercial Sik-haes were 24.5-80.9 mg/100 g and 10.9-28.5, respectively. However, food-grade additives, such as citric acid and monosodium, are occasionally used in commercial Sik-haes to achieve a lower pH or enhance flavor and aroma.

In other to establish the exact determination method of amino nitrogen (AN) in salt-fermented fish sauces, we determined the AN in fish sauces according to the measuring methods and also investigated the main factors influencing on determination method of AN. AN in salt-fermented anchovy sauce increased linearly as fermentation progressed, and was shown the highest amount measuring by the Formol method, followed by the trinitrobenzene sulfonic acid (TNBS) method and the Copper-salt method. AN concentration in anchovy sauces fermented for 12 months was $88.2\%$ and $77.6\%$ for the TNBS method and the Copper-salt method, respectively, on the basis of Formol method. The ratio of AN/total nitrogen (TN) in anchovy sauce fermented for 12 months was higher than that in commercial anchovy sauces. The determination of AN in anchovy sauce by the TNBS method was not affected by salt concentration, and slightly affected by heating. The effect of MSG on AN contents by Copper-salt method was shown higher than those by the Formol method and the TNBS method. The TNBS method was adaptable to measure the content of AN in fish sauce by this study.

This study was conducted to understand the quality characteristics of 20 kinds of commercial salt-fermented anchovy & sand lance sauces by measuring their the chemical compositions and 9 biogenic amines (tryptamine, 2-phenylethylamine, putrescin, cadaverine, histamine, tyramine, serotonin, noradrenaline, spermine) contents. The commercial salt-fermented anchovy sauces contained $65.84{\pm}0.11{\sim}70.60{\pm}0.21%$ of moisture, $20.50{\pm}0.41{\sim}25.60{\pm}0.42%$ of salinity, $0.98{\pm}0.01{\sim}2.05{\pm}0.05%$ total nitrogen, and $1,011.77{\pm}0.00{\sim}1,724.56{\pm}9.72mg/100mL$ of amino nitrogen. Histamine was the major amine detected in salt-fermented fish sauces and it was varied from 421.27 to 1,507.18 mg/kg in salt-fermented anchovy sauces, whereas commercial salt-fermented sand lance sauces contained $67.87{\pm}0.28{\sim}69.63{\pm}0.17%$ moisture, $22.46{\pm}0.28{\sim}26.11{\pm}0.00%$ salinity, $0.92{\pm}0.01{\sim}1.71{\pm}0.05%$ total nitrogen, $878.20{\pm}0.00{\sim}1430.09{\pm}9.77mg/100mL$ amino nitrogen and 419.10~1,025.50 mg/kg histamine, respectively. These findings suggest that the products of salt-fermented fish sauces have pretty much the same in ingredient composition and meet domestic criteria but most those had high biogenic amine contents. Therefore, ingredient composition and biogenic amine content of commercial salt-fermented fish sauce products were practicable evaluation of the quality characteristics.

Nowadays, two types, Yumhae and Sikhae methods, remained as traditional seafood fermentation methods in Korea. In this study, flavor compounds in two types of salt-fermented fishes made by Yumhae method such as anchovy Engraulidae sp., shrimp Caridea sp., squid Decapodiformes sp., big eyed herring Clupea sp., gizzard shad Dorosoma sp. and hairtail Trichiurus sp., and made by Sikhae method such as Alaska pollack Gadus Chalcogrammus and squid. Volatile compounds detected in all salt-fermented fishes were composed mainly of aldehydes (45), ketones (39), alcohols (45), acids (12), esters (47), N-containing compounds (43), aromatic hydrocarbons (37), S-containing compounds (26), furans (10), and miscellaneous compounds (40) in salt-fermented fishes made by Yumhae method. Meanwhile, alcohols (47), terpenes (38), S-containing compounds (22), carbonyl compounds (19 aldehydes, 18 ketones), esters (13), and acids (14). Aroma-active compounds were identified by Gas chromatography/mass spectrometry/olfactometry and aroma extract dilution analysis in salt-fermented anchovy, shrimp and tuna (Thunnini sp.) sauce. Ethyl 2-methylbutanoate (candy/sweet) and 2-ethyl-3,5-dimethylpyrazine (nutty/baked potato-like) were predominant odorants in salt-fermented anchovy, whereas dimethyl trisulfide (cooked cabbage/soy sauce-like), 2-ethyl-3,5-dimethylpyrazine, and (E,E)-2,4-heptadienal (fatty/grainy) in salt-fermented shrimp, and dimethyl trisulfide, 3-methylbutanal (dark chocolate-like), and 3-methylthiopropanal (baked potato-like) in tuna sauce.

This study examined the development of a low-salt fermented seafood product using an ascidian (Halocynthia roretzi), and the optimum processing conditions and quality characteristics of the low-salt fermented ascidian (LSA). The optimum processing conditions for the LSA were as follows. The ascidian was shelled and its muscle sliced into 5 mm widths. This was soaked in a 10% salt and 1% sodium erythorbate solution for 20 min. The solution was drained and then the muscle was soaked in 0.1% sodium bisulfite solution for 1 min. To this was added a 1:1 mixture of anchovy sauce and rice gruel, and it was fermented at $5^{\circ}C$ for 15 days. The moisture content and salinity of the LSA were 75.0-75.4% and 8.0-8.5%, respectively. During salt-fermentation at $5^{\circ}C$ for 20 days, the amino-N content of the LSA increased, and the texture softened gradually. The viable cell counts in early salt-fermentation were $4.2-4.5{\times}10^4CFU/g$, and this decreased gradually. The ratio of saturated fatty acids tended to increase in early salt-fermentation, while that of polyunsaturated fatty acids decreased slightly. Chemical experiments and sensory evaluation showed that the dipping treatment in 1% sodium erythorbate solution and 0.1% sodium bisulfite solution resulted in a good color and prevented browning of the salt-fermented ascidian meat. Moreover, adding anchovy sauce and rice gruel mixture improved the flavor of the LSA.

To investigate the materials in the preparation of kimchi for Koreans in the Commonwealth of Independent States(CIS) a survey was completed by 199 Koreans living in Moscow, Sahalin, Uzbekistan and Jazahstan, In the way to purvey the materials of Kimchi, the frequency to get all the materials of Kimchi in the markets is 74.7% on the whole and by regional groups the frequency is relatively high in Moscow and Kazahstan, For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moxcow and Kazahstan. For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moscow and Kazahstan. 쫴 are younger, or belong to higher emigrant generation, prefer cabbage kimchi. For the additional vegetables many respondents use carrots. For the seasonings, garlic, red pepper powder, and salt are added to Kimchi, but the use of ginger, whole seasame seed, and waxy rice paste is relatively low. The coriander, which is not added to kimchi in Korea, is used in Kimchi By above 80% of the respondents living in the three regions except Sahalin. It is considered to be due to the effect of the western dining cultural area. For the animal materials, 74.4% of the respondents add lightly salted fish to Kimchi and all toe respondents in Sahalin add salt-fermented sea food, the kind of which is mainly salt-fermented croaker. The reasons given for not adding salt-fermented seafood to Kimchi in the three regions except Sahalin, 59.9% of the respondents said it was because of the difficulty to purvey, 21.1% because of the fishy taste, and 16.8% because of not considering the addition of self-fermented sea food in Kimchi. The higher the emigrant generation of respondents, the less seasonings of strong flavor like garlic, red pepper powder, and salt-fermented sea food are used, and the more coriander is used. In the salting of Kimchi preparation, 97.8% of the respondents salt the main vegetables by soaking in brine and its concentration is controlled by experience.

본 연구는 전통적인 발효식품인 식해에 대하여 염농도에 따른 발효기간별 품질특성, 발효 최적조건 및 유통기한 설정, 발효 최적조건에서의 생리활성을 측정하여 우리 전통식품인 식해를 저염화하고 생산 보급함과 동시에 이에 대한 과학적 자료를 제공하는 것을 목표로 하였으며 그 결과를 요약하면 다음과 같다. 본 연구에서 제조한 오징어 식해는 발효기간에 경과함에 따라 염농도가 낮고 온도가 높을수록 pH는 급격하게 감소하였으며, 아미노질소 및 휘발성 염기질소의 함량은 급격하게 증가하였다. 발효최적조건은 5% 염농도의 식해를 $-1^{\circ}C$에서 53일간 발효한 것이었고 유통기한은 염농도 5%의 식해를 $-1^{\circ}C$에서 142일간 저장한 것이었다. 식해는 DPPH 저해활성이 확인되어 항산화 효과가 있으나, hydrolxyl 및 hydrogen peroxide radical 소거능, 항당뇨, 항대장암 및 주름제거 활성은 낮아 기능성 소재로의 활용은 보충연구가 필요하다고 판단된다. 유리아미노산의 조성은 정미 아미노산이 고미 아미노산보다 많아 맛에서 우수하였으며, 시판중인 다른 수산발효식품과 관능적으로 큰 차이가 없었다. 이상의 결과를 고려할 때 $-1^{\circ}C$의 저온에서 식염 5%로 식해를 저염화 시킨다면 현대인의 식기호에 적합한 식품으로 영양학적 측면이나 시장성 측면에서 큰 효과를 낼 수 있을 것이라 판단된다.

소비자의 수용도에 중점을 둔 저염젓갈의 품질 기준을 설정하기 위하여 출하 직전의 시판 젓갈을 반제품과 완제품의 형태로 $30^{\circ}C:$에 저장하여 품질 저하를 시키면서 관능검사와 이에 따른 이화학적 검사를 병행하였다. 명란젓갈의 경우 Brix가 반제품 $47.6\%$ 이상, 완제품 $41.2\%$ 이상이면 합격품으로 판정되었으며 제조회사 별로 절대값의 차이는 있었지만 백색도도 소비자의 수용도가 떨어질 수록 증가하는 경향을 보였다. 반면, 오징어 젓갈은 원료의 특성상 백색도는 기준으로 설정하기 어려웠으나 Brix는 제조회사 별로 기준을 설정하면 소비자 수용도와 상관관계를 설정할 수 있을 것으로 추정되며 pH도 같은 경향을 나타내었다. 결론적으로 저염젓갈의 품질 평가는 관능적 평가와 이론학적 검사를 병행하는 것이 타당하며 이화학적 검사 항목으로 Brix, 백색도, pH 및 hypoxanthine 등을 들 수 있는데 이 중에서 Brix가 가장 좋은 기준이 되며 hypoxanthine은 제품에 따라 차이가 많아 좋은 기준이 될 수 없었으나 오징어젓갈의 경우는 제조 방법이 같을 때 유의할 만한 평가 항목이 될 것으로 판단되었다.
