We determined the contents of 11 biogenic amines in 20 types of cabbage kimchi, 10 types of fish sauce, and 40 types of salted fish purchased from small- and medium-sized grocery stores in Gyeonggi-Do, Republic of Korea, from June to October 2017. The content of each of the biogenic amines in the various types of cabbage kimchi was slightly lower than that in detection amounts of each of the 10 types of biogenic amines and the values reported by Joe et al. The histamine content of all five types of anchovy sauce was lower than the limit set by the European Union (400 mg/kg), but that of three of the five types of sand lance sauce was higher. Analyzing the ratios of the contents of five highly toxic biogenic amines to those of the 11 biogenic amines yielded no quantitative correlation. The estimated daily intake of the five highly toxic biogenic amines in cabbage-kimchi and fermented fish was ${\leq}6mg$.

This study is executed to develop probiotics which produce S-adenosyl-L-methionine (SAM), a methyl group donor of the 5-methyltetrahydrofolate methylation reaction within the animal cell. SAM is an essential substance for the synthesis, activation, and metabolism of hormones, neurotransmitters, nucleic acids, phospholipids, and cell membranes of animals. The SAM is also known as a nutritional supplement to improve brain functions of the human. In this study, the SAM-producing strains are identified in 18 types of salted fish, and then, the strains with excellent SAM productions are being identified, with 1 strain in the Enterococcus genus and 9 strains in the Bacillus genus. Strains with a large amount of SAM production include the lactic acid bacteria such as En. faecium and En. durans, En. sanguinicola, as well as various strains in the Bacillus genus. The SAM-overproducing strains show antibacterial activities with certain harmful microbes in addition to the weak acid resistances and strong bile resistances, indicating characteristics of probiotics. It is possible that the jeotgal-originated beneficial strains with overproducing SAM can be commercially utilized in order to manufacture SAM enriched foods.

Salted semi-dried brown croaker, Miichthys miiuy, has been proposed as a palatable seafood in Korea due to its specific texture, taste, and nutritional content. This study was conducted to characterize the sanitary quality of commercial salted semi-dried brown croaker for the development of high quality salted semi-dried products. The chemical properties ranged from 64.2 to 77.1% (mean $74.7{\pm}3.5%$) for moisture content, from 2.1 to 9.5% for salinity, from 14.1 to 58.1 mg/100 g for volatile basic nitrogen, and from 19.1 to 107.2 meq/kg for peroxide values. The viable cell counts and Escherichia coli were 4.2~8.3 log(CFU/g) [mean: 6.2 log(CFU/g)] and 18>~4.6 log(MPN/100 g), respectively. The chemical and microbial results of commercial salted semi-dried brown croaker suggest that provisions should be established for development of high quality salted semi-dried products.

N-Nitrosamines have been known to be strong carcinogens and are formed by the reaction of nitrous acid with amines. In this experiment the changes in the contents of nitrate nitrite trimethylaminoxide(TMAO) trimethylamine(TMA) and dimethylamine(DMA) during femen-tation of damsel fish were analyzed periodically and N-nitrosamines in a commercial products. N-Nitrosamines were determined by mineral oil distillation methods using gas chromatography-thermal energy anlyzer(GC-TEA) in a commerical product. Nitrate nitrite and amines were quantitate by colorimetric methods. Level of nitrate-N were gradually decreased but nitrite-n was not detected or trace. Contents of dimethlamine(DMA) and trimethlamine were mar-kedly increased while trimethylaminoxide nitrogen was decreased during the fermentation of damsel fish. The change of pH was in the ranges of 5,5-7.0 during fermentation of salted damsel fish. It was out of the optimum pH(3.0-3.4) for the formation of nitrosamine. N-Nitrosamines were not detected in salt-fermented damsel fist but much N-nitrosodimethyla-mine(NDMA) could be detected in salt-fermented damsel fish after adding 0.05M NaNo2 in the acidic condition. The identifaction of NDMA in it was confirmed by mass spectrophotometry. Nitrate decrea-sed during the fermentation of damsel fish. however nitrite was trace level and nitrosamines were not formed in its. This could be supposed that it was due to the rapid consumption of nitrite by amino acid and bacteria.

Eh-jang (fermented aquatic products) of Asia can be classified 4 groups, those are Chot-kal (salted fish guts), Chot-kal Paste, Eh-ganjang (fish sauce) and Shic-hae (lactic acid fermented fish products). The native place of Eh-jang and rice culture is almost same and Eh-jang had been spread out all the area of Asia along with rice culture. Korea has variety of Chot-gal and consumes much Chot-gal that Korea is the culture area of both soybean sauce and Chot-gal. Eh-ganjang had been edible all area of Korea during Chosun Dynasty, but it remains only Southern part of Korea. Korean Chot-gal paste is produced as a form of Kon-chang-yi-chot. Korean Shic-hae had been edible all area of Korea during Chosun Dynasty, but remains at the east coast and some area of Hwang-hae Do and Kyung-sang-nam-do.

The traditional Korean fermented fish products are classified into mainly three groups; Jeot-gal, Aek-jeot, and Sik-hae. Jeot-gal is a salt-fermented fish. Aek-jeot (Eoganjang) is actually a liquid part of Jeot-gal. Sik-hae is a salt-fermented whole or part fisheries with adjuncts. The production of jeot-gal products has been increased constantly. However, there is not enough fishery for raw materials. Recently, consumers have been preferred low-salted foods because they have become aware that high levels of salt cause adult diseases such as hypertension or gastric cancers. The main consumers of jeot-gal are adults above 40~50 years old. Young generation and school nutrition teachers dislike fishery products because of distinct fish smell, small bone, as well as food safety. Therefore, in order to increase the consumption of jeot-gal and extend its industry, jeot-gal should be developed to match the preference of new generation with good safety, health-oriented, and new concept.

This study examined the food culture of Koreans aged over 80-years-old living in the areas of Goorye and Gokseong. The research method was based on examination of individual cases through in-depth interviews. The total number of survey subjects was 38; males constituted 34 percent of the subjects while females constituted 66 percent of the subjects. Average age of male subjects was 85.3 years while average age of females was 84.8 years. The results were summarized in the following properties of the typical and traditional Korean table, which was the most common food life's property in the longevity area of was centered around rice, watery soup, vegetables, and fish. The first, as the supply step's property of food ingredients, various spices and ingredients such as piperitum, tumeric, ginger, garlic, chili pepper, and salted fish were used. Senior persons also supplied fresh vegetables at the kitchen garden, and they led a nature-friendly food life. The second, as the production of food and cooking of food step's property, there were multigrain rice and fermented foods such as soybean paste, kimchi, red pepper paste, salted fish, vegetables picked in soy sauce, etc. The recipe was cookery intermediated with water, soup, steamed vegetables, seasonings, etc., and it was characterized by a deep and rich taste due to the various spices and rich ingredients. The third, as the consumption of food step's property, senior persons regularly ate a balanced diet three times a day. They also had active personal relationships with their neighbors by sharing food, which increased their sense of belonging and improved their life satisfaction.

The purpose of this study were to analyze the consumption patterns of animal foods during the sixteenth century through Shamirok. There were eleven animal foods : beef, pork, chicken, pheasant, deer, roe, lamb, bear, fox, sparrow, and horse. The most frequently consumed were in the order of pheasant, doe, and chicken. There were 44 fish consumed, including flatfish, hairtail, mackerel, flounder, kumlin fish, bass, null fish, codfish, and red snapper, as well as four mollusks and six shellfish. Eggs and fish egg were also consumed. These foods were cooked as Tang(湯), Gui(灸), Po(脯), Hoe(膾), and Sookyook(熟肉), or processed after being dried or salted. The animal foods were mostly consumed as Po and Tang in daily eating and for formal dishes. Fish were mostly consumed as Jockgal or Shikhae. The foods were primarily acquired by donation from local officials or relatives ; secondly by independent poultry farming, fishing, or hunting, along with the production of grain and thirdly through barter with rice and textiles. Food were sometimes traded for profit, but such acts of trading while living ; as wartime refugees was a meager means for living.

The material ratio for preparation of Kimchi in Seoul and Chung Cheong area and the pH, total acidity and NaCl concentration of properly fermented Kimchi were investigated. The kinds of Kimch prepared for the Winter were cabbage Kimchi, Kakdugi, Chonggak Kimchi, Nabak Kimchi, Dongchimi, Bossam Kimchi, and Paek Kimchi. The materials used for chbbage Kimchi were 20 to 25 of ingredients including salted fish and dhellfish. The material ratio of Kimchi was 71.9% of cabbage, 11％ of radish, 2.3-2.6% of green onion, 1.3-1.6% of garlic, 2.7-3.2% of powdered red pepper and 3.9-4.2% of salted fish. The kinds of Kimchi for Spring were cabbage Kimchi, Kakdugi, Chonggak Kimchi, Yulmu Kimchi and cucumber Kimchi. The amount of salted fish and shellfish used were decreased in Spring while vegetables of the season increased. The properly fermented cabbage Kimchi were measured of pH 4.2-4.5 and total acidity of 0.5-0.8%. The favorite concentrations of NaCl were found to be 2.3-2.7% in Winter Kimchi and 1.8-2.4% in Spring Kimchi and in watering Kimchi was shown low as 1.3-1.7%.
