Effects of kimchi and its ingredients, vitamin C and $\beta$-sitosterol on the growth of Helicobacter pylori were investigated. Three kimchi variations were studied: a standard recipe (kimchi I) and two functional variations for cancer prevention and treatment made with organically grown ingredients (kimch II and III). Methanol extracts and juices from kimchi I and III did not inhibit the growth of H. pylori. However, 10 mm and 12 mm inhibition zones were formed by methanol extract and juice from kimchi II, which had higher concentrations of red pepper powder (RPP) than those of kimchi I and III. Among the major kimchi ingredients, methanol extracts of RPP, garlic and ginger substantially inhibited the growth of H. pylori. The maximal inhibition zone (30 mm) was attained with garlic treatment. Inhibitory effects of the RPP, garlic and the sub-ingredient mixture (prepared with radish, garlic, RPP, ginger, green onion, sugar and fermented anchovy juice) on H. pylori were decreased by lactic acid bacteria fermentation. Neither the fermented garlic nor the fermented sub-ingredient mixture inhibited the growth of H. pylori. But, the inhibition Bone of fermented RPP was 12 mm, which was less than the 16 mm inhibition zone formed by the non-fermented RPP. Vitamin C and $\beta$-sitosterol which are known to be functional active compounds of kimchi also showed no inhibitory effect on the growth of H. pylori after 3 days of incubation. Further study is needed to determine why the inhibitory effect is removed or decreased by lactic acid fermentation, and to determine if fresh kimchi and lactic acid bacteria of kimchi can inhibit the growth of H. pylori.

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.

This study was conducted to ivestigate the quality of modeled chinese-cabbage Kimchi. The mutual action of sub-ingredients and optimum mixing conditions were examined by analyses of pH, acidity, content of vitamins, carotenes, number of total microorganism, and Lactobacilli, the activities of softening related to enzymes (polygalacturonase and ${\beta}$-galactosidase), and sensory quality during fermentation. The result about the mutual action of red pepler powder and garlic showed that the pH was decresed as concentration of garlic was higher and that of red peppler powder became lower. Kimchi had unpleasant taste and undesirable odor when the adding ratio of the peper powder and garlic was unbalanced. As the concentration of garlic became higher, the content of vitamin C in Kimchi tissue decreased while that of vitamin C in Kimchi juice increased. The contents of vitamin B1, B2 and carotene increased as the concentration of garlic became lower. The optimum mixing ratio of red pepper powder and garlic evaluated by overall eating quality was 4.66% and 3.45%, respectively. The result about the mutual action of ginger and green onion was that pH became higher as the concentration of ginger was 1.84% and that of green onion was 5.96%. The intensity of fresh taste and odor became stronger as the concentration of ginger increaed to 2.76% and that of green onion decreased to 2.98%. The balance of sour, salty and hot taste became better as the concentration of ginger increased and that of green onion decreased. The optimum mixing condition evaluated by overall eating quality was 2.94% in ginger ＋ 2.78% in green onion. The contents of vitamin B1, B2 and C were high in this condition. The result about the mutual action of leek and salted anchovy juice was that pH became lower as the concentration of leek increased and that of salted anchovy juice decreased. Sour, hot and sweet tastes were good in the condition of leek 12%, salted anchovy juice 4.69%. Palatable, fresh taste and odor became weaker when the one of both sub-ingredients was too much little. The optimum mixing condition evaluated by overall easting quality was 9.76% in leek ＋ 7.32% in salted anchovy juice. The contents of vitamin B1, B2, C and carotene were high in this condition and other sensory qualities were good. The result about the mutual action of salt and sugar was that pH became lower as the concentration of sugar became higher and that of salt became lower. The sweet taste was reduced of hot taste than salty taste. Palatable and fresh tastes were desirable when Kimchi fermented with less salt and more sugar. The optimum mixing condition evaluated by overall eating quality was 3.29% in sugar ＋ 4.80% in salt. The contents of vitamin B1, B1, C and carotene were high in this condition. The result of model Kimchi fermented at 20$^{\circ}C$ was that the number of Lactobacilli in model Kimchi was higher than that of in control Kimchi. The fermentation period was extended under pH 4.0 and the contents of vitamin B1, B1,C and carotene were high through the whole edible period. The activity of polygalacturonase was low, but that of ${\beta}$-galactosidase was high during fermentation.
