Physicochemical and sensory properties of Mul-Kimchi(warery Kimchi) prepared with red cabbage was compared with those of Chinese cabbage or white cabbage. Acidity and turbidity of red cabbage Mul-Kimchi were somewhat higher than those of Chinese cabbage one, which was due to higher soluble solid content in red cabbage Mul-Kimchi. Hunter color a value of red cabbage Mul-kimchi was very much higher than that of Chinese or white cabbage, which was consistent with the data of anthocyanin content. Free radical scavenging activity was much higher in red cabbage Mul-kimchi than in Chinese or white cabbage one. Red cabbage Mul-kimchi had higher values of hardness, fracturability and chewiness during fementation, compared with those of Chinese or white cabbage one. Sensory results showed that there was no difference in overall acceptability among three kinds of Mul-kimchi, although red cabbage one has higher scores of appearance and color than others. Best to the results of this study, it is suggested that red cabbage is a good ingredient for Mul-kimchi.

Brining property and antimutagenic effects of organically cultivaged Chinese cabbage kimchi (OC kimchi) and common Chinese cabbage imchi (CC kimchi) were studied. The salt absorption rate of leaves was faster than that of stems of the Chinese cabbages. Due to the large portion of leaf in organic Chinese cabbage, organic Chinese cabbage(OC) was much faster in terms of salt absorption rate than common Chinese cabbage(CC). The antimutagenic effects of methanol extracts of CC kimchi and OC kimchi were studied against aflatoxin B1(AFB1) using Ames test on Samonella typhimurium TA 100 and N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) using SOS chromotest. Methanol extract from 6 -day fermented OC kimchi at 15 $^{\circ}C$ showed 80% inhibition rate against the indirect mutage, aflatoxin B1 induced mutagenicit where as that from 6-day fermented CC kimchi at 15 $^{\circ}C$ showed 54% inhibition rate in the Ames test. Methanol extracts from 6-day fermented CC kimchi and OC kimchi showed 27 % and 58 % inhibition rate against direct mutagen , N-methyl-N'-nitro-N-nitrosoguanidine induced mutagenicity, respectively in SOS chormotest, thus OC kimchi exhibited higher antimutagenic activity than kimchi.

This study was designed to investigate foreigner preferences for the sensory characteristics of kimchi with different fermentation periods. After fermentation in a 5 freezer for 1, 7, and 15 days, Red Chinese Cabbage Kimchi, White Chinese Cabbage Kimchi, Kkakdugi, Chonggak Kimchi, Cucumber Kimchi, Green Onion Kimchi, and Mustard Kimchi were served to the respondents. The respondents had resided in Seoul and Kyunggi province for 3 years or less, and were from Asia, Europe, and the Middle East. Most respondents (62.9%) consumed a Korean meal daily, and 45% of all respondents reported eating kimchi 3 or 4 times a week. As a result, it can be said that foreigners residing in Korea preferred to eat kimchi as a side dish. Based on the respondents answers, we were able to determine the relative popularity of the different types of kimchi. They were, from most popular to least popular, Red Chinese Cabbage Kimchi, Kkakdugi Kimchi, Cucumber Kimchi, White Chinese Cabbage Kimchi, Chonggak Kimchi, Green Onion Kimchi, and Mustard Kimchi. Among those fermented for 1 day, Cucumber Kimchi was most preferred for its. When evaluating the overall preference of Kimchi, the best was in the order of Chinese cabbage (red)>Kkakdugi>Cucumber>Chinese cabbage (white)>Chonggak>Green onion>Mustard Kimchi. For 1 day in a fermented period, Cucumber Kimchi had the most preferred taste (5.76), appearance (5.66), odor (5.89), and texture (5.70). However, Cucumber Kimchi was least popular after 15 days of fermentation (p<0.01). The most preferred Kimchi after 15 days of fermentation was Red Chinese Cabbage Kimchi. Among the kimchi fermented for 7 days, White Chinese Cabbage Kimchi was most preferred. While foreigners indicated that they were satisfied with all the types of kimchi fermented for 1 day and 15 days, they were not satisfied with any of the kimchi fermented for 7 days, save for the White Chinese Cabbage Kimchi. Kkakdugi Kimchi had very high satisfaction scores for appearance, but low scores in taste. On the other hand, Chinese Cabbage Kimchi had low scores in odor (5.02-5.29), but high in texture (5.37-5.62) and taste (4.80-5.30), which are not factors sensitive to a change in acidity. These results showed that foreigners were generally satisfied with Kimchi, but became less satisfied as the Kimchi ripened. Most foreigners were not satisfied with the types of Kimchi that had a strong flavor. Chinese Cabbage Kimchi became the least sour after fermentation, and Cucumber Kimchi became most sour after fermentation.

The purpose of this study was to investigate the method of making whole Chinese cabbage Kimchi, the family's taste in Kimchi and the reason for disliking the taste of Kimchi in the Taegu area. The results were as follows; 1) Most housewives learned the method of making the Kimchi from their mothers. Method was as follows; First, scatter salt on the whole Chinese cabbage and soak that for 3∼6 hours. After, wash the whole Chinese cabbage 3 times. Then, add red pepper powder, garlic, ginger and salted fermented anchovy as basic seasoning. Be sure to, mix the red pepper powder and salted fermented anchovy until they taste hot and salty. Store the whole Chinese cabbage until they ferment. Afterwards store the whole Chinese cabbage in the refrigerator. 2) It was the whole Chinese cabbage Kimchi that most family members preferred. 3) Among the family members, the old age group preferred newly made Kimchi because of the cool and fresh taste. The adult group preferred fresh taste, also smell and peculiar taste of the seasoning were important. The adolescent group preferred fresh taste and sour taste. 4) It shows that most of the family likes Kimchi, and among the family members, about 25% of the sons and daughters dislike Kimchi. And it shows that all family members dislike salty taste. 5) The older housewives’ Kimchi was preferred over the younger housewives’ Kimchi.

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 .

To enhance the antimutagenic and anticancer activities of chinese cabbage kimchi, 13 kinds of kimchi, which were different kinds and levels of sub-ingredient added kimchi, were prepared and fermented at 15℃ for 1 day and then at 5℃ up to pH 4.3. The antimutagenic effects of the methanol extracts of the kimchi were studied by using Ames mutagenicity test in Salmonella typhimurium TA100 and SOS chromotest in E. coli PQ37. Among the kimchi samples, high ratio of red pepper powder(7%) and garlic(2.8% or 5.2%) added kimchi, 1% chinese pepper powder added kimchi and organic cultivated chinese cabbage kimchi significantly reduced(p<0.05) the mutagenicity induced by aflatoxin B1(AFB1) in Ames test and SOS response against N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) in SOS chromotest, and also the kimchi inhibited more effectively(p<0.05) the survival and growth of AGS human gastric adenocarcinoma cells than the standarized kimchi on the SRB assay, MTT assay and growth inhibition test. These results suggest that the antimutagenic and anticancer activites of kimchi can be increased by the sub-ingredients such as organic cultivated chinese cabbage, red pepper powder, garlic and chinese pepper powder.

Hydroponic cultivation is a technology of raising crops without use of soil. Generally farmers use the method of DFT(deep flow technology)to grow leafy or fruity vegetables; however, systematic and scientific researches are insufficient on this matter. This study investigated the possibility of cultivating Chinese cabbage steadily year long by using the method of DFT. Chinese cabbage was cultivated hydroponically with and without Ge addition, used to prepare kimchi, and the chemical and microbiological characteristics of kimchi were compared. The basic hydroponic cultivation condition was as follows: 30 days after seeding, the raised seeds were moved to a hydroponic bed and given underground water for 3 days so the roots grow normally Standard nutrient solution was provided and the early electric conductivity concentration was maintained between 1.5∼2.5 thickness. The temperature of the solution was maintained between 10 ∼25$^{\circ}C$ to allow the growth of Chinese cabbage. When soil-cultivated, organically cultivated and hydroponically cultivated Chinese cabbages were compared, hydroponically cultivated cabbages were smaller in size and showed less ability to build up and fold leaves into a head, but showed better quality than organically cultivated cabbages. The contents of protein and fat showed no significant differences. The contents of water. Ca, P, Fe, Vitamin A and Niacin were higher in control and Ge-added cabbages compared with soil-grown cabbage. There was no difference between soil-cultivated Chinese cabbage kimchi and hydroponically cultivated Chinese cabbage kimchi.

Three kinds of kimchi using Chinese cabbage, leafy radish and mustard leaf were prepared by conventional method and stored at 5$^{\circ}C$ or 2$0^{\circ}C$ for 13 dyas. During storage at both temperatures, changes of the amounts of salt and ascorbic acid, pH and total acidity were determined, and the relationship of the decomposition of chlorophylls with the production of their derivaties was studied. At both storage temperatures, salt concentration of Chinese cabbage kimchi(3.7%), leafy radish kimchi(3.6%), mustard leaf kimchi(3.5%) was relatively constant during the entire storage period. However, pH and total acidity wre fluctuating with the remarkable changes during 3 days of storage. Ascorbic acid content was slowly decreased during the storage period and the decompositin rate of ascorbic and was greater at 2$0^{\circ}C$ than 5$^{\circ}C$. Among the kinds of kimchi tested, mustard leaf kimchi with the slow decomposition rate of ascorbic acid contained relatively high ascorbic acid content, while leafy radish kimchi contained the lowest content. At both storage temperatures, the production of pheophytin and pheophorbide from decomposition of chlorophyll was least in mustard leaf kimchi, but similar production rates in leafy radish and Chinese cabbage kimchi were observed.

The effect of frozen storage on some physicochemical and sensory quality of salted Chinese cabbage and Kimchi were investigated. The texture of the fresh Chinese cabbage was preserved better by emersion quirk freezing or predrying than by air slow freezing or no predrying while no effect was measured on the salted Chinese cabbage. The salted cabbage had less frozen damages than the fresh one and had the similar texture characteristics of the fermented Kimchi. The frozen Kimchi had the similar overall quality to the unfrozen fermented Kimchi in spite of a little higher chewness values. The color of the salted Chinese cabbage was a little changed to pinkish after 3 months frozen storage but Kimchi was maintained the good quality after 6 months.

In vitro anticancer effect of Chinese cabbage kimchi fractions was investigated by using human cancer cells, AGS human gastric adenocarcinoma cells and HT 29 human colon adenocarcinoma cells. The Chinese cabbage kimchi(fermented for 4 days at 15oC) was fractionated into 7 groups, methanol extract, hexane fraction(fr.), methanol soluble fr., dichloromethane fr., ethylacetate fr., butanol fr. and aqueous fr.. Chinese cabbage kimchi fractions inhibited the growth of AGS and HT 29 cancer cells as dose dependent. In particular, the dichloromethane fr. showed the highest inhibitory effect among other fractions. When the dichloromethane fr.(0.2mg/ml) was treated, the number of AGS and HT 29 survival cancer cells reduced to 12$\times$104/ml and 11$\times$104/ml compared to 166$\times$104/ml and 50$\times$104/ml of the controls, respectively. Chinese cabbage kimchi fractions also inhibited the DNA synthesis of the cancer cells. They inhibited the DNA synthesis of AGS human gastric adenocarcinoma cells more efficiently than that of HT 29 human colon adenocarcinoma cells. These results indicate that Chinese cabbage kimchi fractions show in vitro anticancer activity and the dichloromethane fr. among them reveals the highest effect.
