김치 발효중 대장균군의 잔존 현상을 확인하였고 대장균군을 가식 기간에서도 조기에 사멸시킬 수 있는 방법을 모색하였으며 동시에 nisin의 김치 발효에서의 역할을 평가하였다. 대장균(E. coli B34)을 김치 제조시 $10^6\;CFU/g$이 되도록 접종하였을 때 pH, 산도의 변화, 총균수, 총젖산균수, Leuconostoc속 젖산균의 수 등에 차이가 거의 없었다. AITC 그 자체나 AITC를 생성하게 하는 고추냉이, 그리고 김치제조시 정상적으로 첨가하는 마늘이 대장균군에 대한 조기사멸효과가 있었는데, 마늘은 2.0% 이상, AITC는 50ppm이상, 고추냉이가루 0.4%이상에서 대장균군의 사멸효과가 좋게 나타났으나, nisin의 경우는 $100{\sim}2000\;I.U./g$에서 대장균군이 대조구보다 더 오랫동안 잔존하였으며 김치의 저장성 연장효과는 미미하였다. MMTSOO나 겨자가루는 대장균군 조기사멸효과가 나타나지 않았다. 김치 재료로 쓰이는 원료중에서 절인 배추에는 $10^4$, 깐마늘에는 $10^2{\sim}10^5$, 고춧가루에는 $10^4{\sim}10^5$, 생강에는 $10^7$, 그리고 파에는 $10^3{\sim}10^5\;CFU/g$의 대장균군이 존재하였다. 통마늘과 공장생산 고춧가루에는 대장균군이 검출되지 않았다.

장내젖산균인 L. acidophilus를 이용한 배추김치를 제조할 목적으로 이균의 배추김치제조에의 이용성 조사, 부재료가 균의 생육에 미치는 영향을 조사하고, 김치담금재료에 부착한 김치숙성과 관련이 없는 각종 미생물을 오존수 또는 개스상의 오존을 처리하여 제거시킨 후 숙성에 따른 비타민류의 변화, 조직 및 즙액내의 당류의 변화, 균수의 변화 및 관능적 품질을 조사하였다. L.acidophilus는 배추즙액에서의 생육도로 보아 김치제조에의 이용성이 양호하였다. 또 부재료인 고추는 김치에서의 사용범위인 1~2%첨가로 생육을 다소 촉진하였으며, 생강과 마늘의 경우는 상당히 저해하여 부재료의 사용으로 숙도조절 가능성이 인정되었다. 김치부재료에 6mg/L/sec의 오존 및 오존수를 1시간동안 처리한 결과 재료에 부착한 총균의 잔존율은 6~20%범위였으며, 김치담금비율에 준하여 재료를 혼할 경우의 제균율은 80~90%수준이었다. 재료를 오존을 처리한 후 L. acidophilus를 첨가하여 김치를 숙성시킨 결과 숙성이 촉진되었으며, 이용가능한 당류가 없어질 경우 세포벽다당류를 분해하여 이용하였으며, 숙성과정중 비타민 B$_1$과 C의 함량이 일반김치에서 보다 높았다.

Radish kimchi is a typical side-dish in Korean traditional food and is a way of keeping vegetables for a extended period using fermentation. This study examined the classification, usage, eating history, variety, and recipes of Korean radish kimchi through ancient and modern era literature. The Korean radish kimchi were categorized into six groups: kkakttugi, seokbakji (or nabakkimchi), dongchimi, jjanji, jangachi, and jangkwa. According to the record, the eating history of radish kimchi comes from before the age of the Three Kingdom period. Radish was preserved in salt, vinegar, soybean paste or lees of fermented liquor in the early times. This pickled radish was not supposed to be watery. Radish kimchi was divided into watery kimchi (dongchimi) during the period of United Silla and the Koryo Dynasty. Kimchi was mixed with Chinese cabbage to make seokbakji or nabakkimchi. Up to the early Chosun Dynasty, the key ingredient of kimchi was radish. After the middle of the Chosun Dynasty, kimchi was mixed with red pepper powder, salted fish, soybean sauce, and various ingredients. There were many kinds of radish kimchi during the late Chosun Dynasty. In the 11 Korean recipe books published within the past 100 years, there are nine kinds of kkakttugi, three kinds of seokbakji, four kinds of dongchimi, three kinds of jjanji, nine kinds of jangachi, and five kinds of jangkwa. Kkakttugi (cubed, sliced or julienne radish) was pickled with salt, red pepper powder, garlic, green onion, oyster, sugar, salted fish, and more. Seokbakji and nabakkimchi were not as salty, so they could not be preserved as long. Dongchimi (watery radish kimchi without red pepper powder) was made of radish, water, salt, 18 side ingredients, 13 condiments, and seven garnishes. Jjanji was pickled to be very salty and was eaten during summer. Jangachi can be used as a regular side dish and is made of radish or dried radish slices pickled or seasoned with salt, soy sauce, vinegar, soybean paste, lees of fermented liquor, and spices. Jangkwa is used as a stir-fry method and has been segregated from jangachi relatively recently.

Kimchi is a traditional Korean food prepared by fermenting vegetables, such as Chinese cabbage and radishes, which are seasoned with various ingredients, including red pepper powder, garlic, ginger, green onion, fermented seafood (Jeotgal), and salt. The various unique microorganisms and bioactive components in kimchi show antioxidant activity and have been associated with an enhanced immune response, as well as anti-cancer and anti-diabetic effects. Red pepper inhibits decay due to microorganisms and prevents food from spoiling. The vast amount of biological information generated by academic and industrial research groups is reflected in a rapidly growing body of scientific literature and expanding data resources. However, the genome, biological pathway, and related disease data are insufficient to explain the health benefits of kimchi because of the varied and heterogeneous data types. Therefore, we have constructed an appropriate semantic data model based on an integrated food knowledge database and analyzed the functional and biological processes associated with kimchi in silico. This complex semantic network of several entities and connections was generalized to answer complex questions, and we demonstrated how specific disease pathways are related to kimchi consumption.

Antimutagenic activity of crushed kimchi fermented with starter under various conditions such as temperature(5-20$^{\circ}C$), salt concentration(2-10%), addition rate of starter (0-20%) was investigated. The kimchi was fermented with crushed Chinese cabbage without salting, red pepper powder, crushed garlic, crushed ginger, anchovy juice and starter. Well fermented kimchi juice(fermented at 10$^{\circ}C$ for 15 days) and sterilized radish juice was used as a source of lactic acid bacteria and starter medium, respectively. Antimutagenic activity showed the highest in the crushed kimchi fermented at 15$^{\circ}C$ for 15 days, 4% salt concentration, 5% starter added, respectively. The inhibition rate of mutagenic activity of the kimchi against S. typhimurium TA98 induced by NQO and S. typhimurium TA100 induced by MNNG was 56.41% and 60.11%, respectively. And the inhibition rate of the kimchi juice showed 56-60% per 100ul.

This study was conducted to investigate the potential origin of Weissella species, which were found in ingredients of kimchi, such as salted Chinese cabbage, radish, green onion, red pepper powder, pickled shrimps, garlic, and ginger. Ten strains of Weissella species (Weissella thailandensis, W. kimchii, W. koreensis, W. minor, W. halotolerans, W. hellenica, W. kandleri, W. confusa, W. viridescens, and W. paramesenteroides) and lactic acid bacteria isolated from ingredients of kimchi were analyzed by SDS-PAGE of whole-cell proteins. Several strains with patterns identical to those of Weissella kimchii were isolated from green onion. On the basis of biochemical characteristics and 16S rDNA sequence comparisons, these strains were identified as Weissella kimchii, suggesting green onion as a major origin of Weissella kimchii found in kimchi.
