The purpose of this study is to investigate the sensory characteristics of Toha-jeot added cabbage kimchi by Koreans and Japanese. The sensory evaluation was conducted for the following 9 items such as color, savory taste, carbonated taste, sour taste, hot taste, salty taste, off flavor, texture and overall preference. Sensory evaluation of kimchi was tested by Koreans or Japanese whose ages vary from 30 to 50 years old and each group had 25~30 evaluators. Kimchi at different stages of fermentation day 0, 10 and 18th was evaluated. Saltiness of kimchi was 1.5~2.1% through the fermentation period and pH of kimchis was decreased from pH 5.4~5.6 to 4.3~4.4 during the fermentation. The sensory evaluation of Toha-jeot added cabbage kimchi by Koran and Japanese showed the differences in evaluation as the fermentation proceeded. The color, texture and overall preference of Toha-jeot added cabbage kimchi fermentation for 10th days was scored significantly high by Korean group while the score for the savory taste was increased as the fermentation proceeded. The hot taste preference of Toha-jeot added cabbage kimchi fermented 18th days scored significantly high and also increased as the fermentation proceeded by Japanese group. The overall preference of Toha-jeot added cabbage kimchi by Japanese group was higher than that of control cabbage kimchi tested at 10 and 18th days fermentation.

Kimchi has been one of the main menu on our dining table at all seasons as the best matching side dish with boiled rice. Kimchi was privately made in every household, and it has been commercially made for military feeding since Korean Civil War in 1950. Commercialized kimchi in can was also made for soldiers sent to Vietnam in late 1960s and for workers sent to Middle East in 1970s. As industry was growing, the number of people dining out increased, and with export to Japan in 1980s. Kimchi industry had greatly expanded until 1990s. However. the growth of industry has slowed down as individual consumption decreased and import from China radically increased. Since 2000, kimchi industry has been growing again focusing on quality improvement, which is possible due to up-to-date system and high standard sanitation control in manufacturing. Kimchi becomes the most important cultural product at the core of our food culture as all Korean people realize that it contains not just a wide variety of ingredients but unique flavors of each local areas and sincere heart of local people. Commercialization of kimchi will increase even though its consumption decreases as people's dietary life changes.

The antimutagenic effects of buchu kimchi and Chinese cabbage kimchi and theri cytotoxic effects against human cancer cell line were investigated in the Salmonella typhimurium system and MTT assay, respectively. Leek and Chinese cabbage were aslo evaluated in the same system. Buchu kimchi was fermented at 15 $^{\circ}C$ for 4 days . Buchu kimchi samples showed somewhat higher antimutagenic effects against aflatoxin B1(AFB1) than CHinese cabbage kimchi in Salmonella typhimurium TA100 strain. There was no difference onthe antimutagenic activity according to the length of fermentation . Leek exerted stronger antimutagenicity against AFB1 than Chinese cabbage in the Ames assay. In MTT assay, 6-day fermented buchu kimchin revealed the highest cytotoxicity against AGS human gastric adenocarcinoma cells in which 62% and 82% of the inhibition were observed wiht the addition of 100ug, 400ug/well, respectively. Buchu kimchi samples caused 60~70% inhibition on the proliferation of HT-29 at 400ug/well. Leek exhibited higher antiproliferative effect against both AGS cells and HT-29 cells than Chinese cabbage in MTT assay. From these results, it is considered that buchu kimchi has stronger antimutagenic and in vitro anticancer effects than Chinese cabbage kimchi and the high inhibition rate of buchu kimchi probably results from leek, the major ingredient of buchu kimchi .

Although Korean people like Kimchi very much, Kimchi is generally limited in sodium restricted diet of hospital food service operation. The use of Kimchi in sodium restricted diet can improve appetite and nutritional status of patients. In this study, four kinds of Kimchi(Kwail-Nabakji, susan-Nabakji, suk-Gakduki, Oi-Gakduki) were Prepared and analyzed for their Sodium contents. the preference of Kwail-Nabakji and susan-Nabakji was compared with low sodium Juciy kimchi provided in the hospital in 25 patients who were restricted in sodium intake. The result were as follows: 1. In 2 kinds of low sodium juicy Kimchi that salt not added sodium contents of kwail-Nabakji(fruti-juicy Kimchi) and susan-nabakji(ginseng-Kimchi) were 17.8 mg/100g a 11.0 mg/100g, respectively. 2. The otehr 2 kimchies were prepared by adding dilute salted shrimp broth. suk-Gakd uki(boild radish-Kimchi) and Oi-Gakduki(cumcuber-Kimchi) had 89.8 mg/100g and 111.6 mg/100g sodium, respectively. 3. Na/k ratios of 4 kinds of low sodium kimchi were in the range of 0.34-0.62 which were lower than that of general Kimchies. 4. The patients preferred kwil-nabakji and susan-nabakji to low sodium juicy Kimchi provided in the hospital, and most liked Kwai-Nabakju. Therefore low sodium Kimchies can be recommended in sodium restricted diet because they have lower sodium contents then general Kimchies.

Inhibitory effects of kimchi extracts on arcinogen-induced cytotoxicity and transformation in C3H/10T1/2 cells were studied. The methanol extract (500㎍/ml) of fresh (unfermented kimchi), and 3-week-fermented kimchi (properly ripened kimchi at 5℃) inhibited 3-methylcholanthrene (MCA)-induced cytotoxicity in C3H/10T1/2 cells by 84 and 99%, respectively. The inhibitory effect of 3-week-fermented kimchi was higher than that of the fresh kimchi at same test condition. The methanol soluble fraction, and haxane extract of 3-week fermented kimchi also surpressed the cytotoxicity of FC3H/10T1/2 cells mediated by 7,12-dimethylbenz[a]anthracene(DMBA) and N-methyl-N'-nitro-N-nitrosoguanidine(MNNG). Furthermore, MCA-induced transformation of C3H/10T/1/2 cells was significantly inhibited by the methanol soluble fraction of 3-week fermented kimchi. With these results, we suggest that kimchi might have anticarcinogenic effect in part due to inhibition of carcinogen-induced cytotoxicity and transformation of C3H/10T/1/2 cells.

To produce a high-quality Kimchi product, molten salt was used for the Kimchi. Changes in the physiochemical properties and functional compounds were analyzed during fermentation. The salinity of bay salt Kimchi was higher than that of the molten salt Kimchi. The fermentation speed of the lactic acid bacteria in the molten salt Kimchi was significantly faster. To evaluate the effects of the salts on the changes in the functional compounds during fermentation, the antioxidant activity, total phenolic compounds (TPC), flavonols, phenolic acids, and glucosinolates in Chinese cabbage were analyzed. In the first 9 days, antioxidants were decreased during this fermentation period and then, increased after that. TPC was slightly increased for all the conditions after 40 days fermentation. Kaempferol was a major flavonol but had a relatively larger decrease in the molten salt Kimchi than in the bay salt samples. Phenolic acid did not show any significant difference among the samples. The glucosinolate contents were significantly decreased in all the conditions of Kimchi during the fermentation period. Consequently, the molten salt greatly affected the fermentation speed of Kimchi and the total characteristics of the Kimchi lactic acid bacteria. Although the functional compounds of Chinese cabbage were decreased during the fermentation of Kimchi, this decrease did not profoundly deteriorate the food quality. Therefore, high-quality Kimchi with enhanced bioactivity will be available if appropriate Chinese cabbages that have enhanced functional compounds are used.

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.
