시판 젓갈류의 품질표준화 및 객관적이고 과학적인 품질평가를 위한 기초자료를 얻고자 현재 국내에서 수요가 많은 새우젓, 오징어젓 및 조개젓을 대상으로 미생물적, 관능적 및 화학적 품질특성을 검토하였다. 시판 새우젓의 관능검사 결과와 아미노태 질소함량은 상관계수가 0.9138로 가장 높게 나타났으며, 약 $150{\sim}300\;mg%$ 범위에서 아미노태 질소의 함량이 높을수록 기호도가 높았다. VBN 함량은 약 $25{\sim}70\;mg%$ 정도로 함량이 많을수록 기호도가 높았고 관능검사 결과와 높은 상관관계(0.7607)가 있어 새우젓 제품의 품질평가에 적합하였다. 시판 오징어젓은 pH가 6.0이상이었을 때 기호도가 높아 관능검사와의 상관계수가 0.8467로 나타나 단순히 pH만으로도 오징어젓의 품질을 평가할 수 있으며 VBN 함량은 30 mg%이하의 제품에서 기호도가 높았으며 상관계수도 0.9581로 가장 높게 나타나 pH와 함께 품질평가에 적합한 실험항목이었다. 시판 조개젓은 VBN의 함량이 40 mg% 미만이었으며 함량이 낮을수록 관능검사 결과가 높아 관능검사와의 회귀분석에 의한 상관계수는 0.9497로 높게 나타나 조개젓의 품질평가에 적합하였다.

저염 명란젓에 sulfite 염을 첨가하여 숙성 중에 일어나는 여러 가지 화학적 및 미생물 변화를 측정하여 저염 젓갈의 shelf-life에 미치는 결과를 요약하면 다음과 같다. Bisulfite 및 metasulfite 명란젓은 숙성초기에 pH가 급격하게 감소하였다가 그 후 서서히 감소하였으며 젖산 생성량도 증가하였다. 숙성이 진행됨에 따라 아미노태 질소량은 감소 경향을 나타내었으며 metasulfite 명란젓이 가장 높은 생성량을 나타내었다. Bisulfite와 metasulfite의 첨가는 숙성 후기의 VBN 및 TMA 생성 억제에 효과적이었으며, 숙성 초기의 TBA 생성을 억제하였다. Bisulfite 및 metasulfite는 fungi를 포함한 미생물의 성장을 현저하게 저해하였다. Sulfite 염 첨가시의 추정되는 shelf-life는 대조군, sulfate, bisulfite및 metasulfite인 경우 각각 16, 14, 20 및 24일이었다.

This study examined the food culture of the Koryo Dynasty during the early 13th century based on the records of wooden tablets and marine relics from the 1st and 2nd ships of Mado wrecked at sea off Taean while sailing for Gaegyeong containing various types of grain paid as taxes and tributes. The recipients of the cargo on the 1st ship of Mado were bureaucrats living in Gaegyeong during the period of the military regime of the Koryo Dynasty, and the place of embarkation was the inlet around Haenam (Juksan Prefecture) and Naju (Hoijin Prefecture) in Jolla-do. On wooden tablets were recorded 37 items of rice, cereal, and fermented foods. The measures used in the records were seok [石-20 du (斗)] for cereal, seok [15 du, 20 du] for fermented soybean paste, and pot (缸) and volume (斗) for salted fish. The places of embarkation on the 2nd ship of Mado were Jeongeup (Gobu Prefecture), Gochang (Jangsa Prefecture, Musong Prefecture), etc. On wooden tablets were recorded 29 items of rice, cereal, fermented foods, seasame oil, and honey. The volume measure for yeast guk (麴), the fermentative organism for rice wine, was nang [囊-geun (斤)], and the measure for sesame oil and honey, which were materials of oil-and-honey pastries and confections, was joon (樽-seong, 盛). Honey and sesame oil were luxury foods for the upper-class people of the Koryo Dynasty, and they were carried in high-quality inlaid celadon vases in Meibyung style. Food names and measures written on wooden tablets and actual artifacts found in the 1st and 2nd ships of Mado are valuable materials for research into agriculture, cereal, and fermented foods of the Koryo Dynasty in the early 13th century. Besides, relics such as grains and bones of fish and animals from the Koryo Dynasty are expected to provide crucial information usable in studies on food history of the Korean Peninsula.

This study was conducted to investigate the standardization of kimchi and related products. There are about 339 kinds of kimchi and related products in Korea. Half of those various kimchi was 50% of the total products, and the other groups are in the order of Jangachi (high salted vegetable pickles, Saengchae (a salad type kimchi), Kakduki(reddish kimchi), Keotjulyi(nonfemented kimchi), Pickles, Seobakji (kimchi based on raddish, fish and other ingredients) and Shickgae (lactic fermented fish products). About 200 ingredients (chinese cabbage, raddish, cucumber, other vegetables, fruits, seaweeds, fish, meat etc.) were used for those products. Tongbaechu kimchi (whole headded chinese cabbage kimchi) and Possam kimchi (wraped kimchi with chinese cabbage leaves) were made by about 30 ingredients, respectively. Kakduki, Oyster-kakduki, Chonkak kimchi (kimchi based on small raddish with leaves) and Tongchimi (raddish kimchi with brine soup) were made by raddish and more than 10 ingredients, but the subsidiary ingerdients were less than that of chinese cabbage kimchi. Other products such as Yulmu kimchi and Oisobaki (a cucmber kimchi) were also dicussed.

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 ${\leq}6mg$.

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.

The myeolchi-jeot samples were divided into different groups with or without the supplementation with biogenic amines. Subsequently, the samples were placed in an oven at $80^{\circ}C$ for 1 hr to allow the chemical reaction to proceed, and then were analyzed for N-nitrosamine contents using GC-TEA. N-nitrosamine was not detected in any of the myeolchi-jeot samples which had been treated with/without sodium nitrite. On the other hand, the yield of N-nitrosopyrrolidine from 1,000 mg/kg of putrescine and spermidine in the myeolchi-jeot samples (treated with 5 mg/kg of sodium nitrite) was 0.002 and 0.014%, respectively. N-nitrosamine was not produced from any other biogenic amines like, histamine, tyramine, cadaverine and spermine. In addition, curing and heating were the factors which influenced the formation of N-nitrosamine during the nitrosation of biogenic polyamines. For the formation of N-nitrosamine in the food systems, treatment with sodium nitrite and heating at appropriate temperature along with the satisfied supplementation of biogenic polyamines are required.
