This study was conducted to compare the perception and the criteria for tasty Kimchi between Korean focus group and American focus group. The perception of taste of Kimchi by American focus group was rather simple than that of Korean focus group. American focus group considered spicy, sweet and crunchy properties as the most desirable characteristics of Kimchi. Besides that properties, Korean focus group considered complicated characteristic taste, e.g. a combination of hot, sour, savory, salty, sweet and fresh taste and refreshing properties as essential factor in tasty Kimchi. Korean focus group had more peculiar descriptors in taste and American in mouthfeel and texture.

This study surveyed the Kimchi preference for French, potential Kimchi improvement for French market adaptation and Kimchi application for French cuisine, with the aim of spreading the recognition of Kimchi throughout the world, especially in France, by giving information and developing local types which could be expected to be suitable for utilization of French food life. The Kimchi experience of 100 persons in France was surveyed for the study. Most (72.0%) had no experience. For the preference of red Kimchi in palatable ripening period depending on sexes, women had a higher Score (M=4.04${\pm}$0.88) than men (M=3.91${\pm}$0.91) did. In the case of white Kimchi, women had a higher score (M=4.09${\pm}$0.90) than men (M=3.98${\pm}$1.01) did, also. The attraction reason of Kimchi for males was the chewing feel, healthy food and spicy taste, and for females was the chewing feel, spicy taste and healthy food orderly. However, the other side of the Kimchi improvement point was decreased fermented order, spicy taste and salinity, but improved orderly appearance. Thus, the Kimchi development point for French was keeping the crisp chewing feel, fermenting better at the fresh than ripening, reducing the fermented order and controlling the spice taste. Types of fermented food similar to Kimchi were involved in more than 80% of French cuisine, with the most common in the survey being pickled cabbage, followed by cabbage salary and fermented salted food orderly. The Kimchi utility as a raw ingredient or a seasoning for French cuisine was firstly as an accompaniment with meat cuisine, followed by appetizer, eating with cooked rice, eating with fish cuisine, orderly for males, whereas for females it was eating with cooked rice, followed by appetizer, eating with fish cuisine and eating with fried potato and orderly. Thus, the French had a similar view to Koreans regarding the accompaniment of Kimchi meat. The developed fusion Kimchi foods were 'Poitrine de porc caramelisee au miel et Kimchi', 'Blanc de barbue aux crevettes roses et Kimchii', 'Kimchi SpringRoll' and 'Potage saint-Germain aux Kimchi'. The French preference for Kimchi utility was generally a high score for the eating the cuisine in which Kimchi was added to meat cuisine.

In the development of a nutrient enhanced functional food, kimchi was produced by using high $\gamma$-aminobutyric acid (GABA) producing lactic acid bacterium as a starter strain. The strain isolated from kimchi was identified by using an API kit and named Lactobacillus sp. OPK 2-59. Kimchi was produced by 3 methods 1) monosodium glutamate (MSG) added (M group); 2) starter added (S group); 3) MSG+starter added (M&S group). The produced kimchi was fermented for 24 hr in an incubator at a temperature of $15^{\circ}C$ and stored at $0-1^{\circ}C$ to examine its characteristics. The M&S group exhibited a sharper increase in acidity and a steeper fall in pH as well as a higher number of lactobacilli. The M&S group kimchi had 18 mg/100 g (fresh weight, f.w.) of GABA, whereas the M and S group each had 6 mg/100 g (f.w.) GABA. According to functional evaluation, the M&S group kimchi, which has higher GABA, was not significantly different in taste, color, texture, or smell, but the M&S group was generally superior. In summary, using Lactobacillus sp. OPK 2-59 and MSG, a high quality kimchi with increased GABA content can be produced as a functional food.

The sucrose, MSG, fresh oyster and salted-fermented anchovy and shirmp were added into Kimchi in the concentration range of $1{\sim}3%$ and studied for their effects on the changes in chemicl properties and fermentation rate. The control Kimchi was prepared with addition of 2% red pepper, garlic, Welsh onion and 1% ginger. It was found that the fermentation rate was increased as the concentration of all of ingradients tested increased. Among them M.S.G affected most significantly. However, ascorbic acid formed was reduced for those Kimchi added with salted-fermented anchovy and shrimp while the changes in pH and titrable acidity was affected a little.

This study was attempted to investigate preference characteristics affecting for winter kimchi. Questionnaire were collected by 646 nationwide households during 3 months from December 2000 in Korea, and the data were analyzed by SPSS program. The results were as follows: (1) Seven minor ingredients including red pepper, garlic, ginger, green onion, paste (e.g. glutinous rice, rice and/or wheat flour paste), sugar and sesame were user in high preference for making winter kimchi in that odor. Seafoods (oyster, shrimp, Alaska pollack, yellow corvenia, squid and hairtail) were also utilized for making winter kimchi related with regional characteristics. (2) Two jeotkals, anchovy and anchovy juice, were popular ingredients for winter kimchi in southern region, while shrimp jeotkal in middle region including Seoul, Chungnam, Chungbuk, Daejeon, Daegu, Gwangju and Jeju northern sand lance juice jeotkal in western region, respectively. (3) Two kimchi, green onion and leek kimchi were high favored by people in spring regardless of region, and baby radish kimchi and cucumber kimchi in summer, pony-tail kimchi and gutjuli (fresh kimchi) in autumn, respectively. Except for winter cabbage kimchi, however, dongchimi and godulbaegi (Korean lettuce kimchi) were high favorite kimchi in winter. It was estimated that Koreans consume about 80 g of kimchi per person per day.

Kimchi has been worldwide recognized as a traditional Korean fermented food, In the Chinese cabbage's pickling, salt content of evenly penetrate into the tissue affects on the texture of matured kimchi, But the previous method which usually using brine salting has a disadvantage of uneven penetration of salt into the leaves and stems. The purpose of the study is to develope the method which produce superior kimchi by evenly penetrate the salt into the tissue rapidly, The dry salting method is directly spread the salt on the surface of chinese cabbage as percentage in weight with 10, 12, 14, 16%(s) and pickled in this state for 5 hours. Brine salting method is soaking chinese cabbage in the 16% salt solution(16%B) for 20 hours. Sensory evaluation, contents of salt, properties of mechanical hardness and micro structure were studied among fresh cabbage, 16%B and 10, 12, 14, 16%(s) cabbage, The result of salt contents in all groups of pickled chinese cabbage were significantly increased compared with fresh cabbage. The compressive force of cabbage's steams by mechanical measurement was significantly decreased but cutting force was increased. In pickled cabbage, the cutting force was the highest correlated with salt content, In the sensory evaluation, the salty taste of leaves and chewy degree were significantly increased, but the hardness and crips of the stems were significantly decreased by increasing salt contents. Therefore the dry salting is the most excellent pickling method in small amount of kimchi production by saving salt amount and time, furthermore due to even penetration of salt into leaves and stems.

The quality characteristics of pH, total acidity, and color of Kimchi juice and organoleptic properties of taste, odor and texture were studied for their changes during Kimchi fermentation. Kimchi was prepared by salting in 15% NaCl solution for 2 hours followed by addition of other spices and fermentation at $4-35^{\circ}C$. The results of pH decrease and acidity increase suggested that Kimchi fermentation can be classified into 3 steps of initial, intermediate and final stages. The activation energyes calculated from the intermediate stage where pH decreased rapidly were 15.67Kcal/mole for pH change and 18.99Kcal/mole for acidity change. The Hunter color values of Kimchi liquid showed that it becomes a weak greenish bluecolor as the fermentation progressed. Sensory characteristics of fresh sourness taste and odor and fracturability of Kimchi were increased until pH reached approx. 4.0 and then decreased while moldy taste and odor was increased rapidly thereafter.

The possible use of tea catechins as natural preservatives for kimchi was investigated in this study. Tea catechins separated from tea leaves had antimicrobial activity against microorganisms related to kimchi fermentation, such as Leuconostoc mesenteroides, Lactobacillus plantarum, Lactobacillus brevis, Pediococcus cerevisiae, Streptococcus faecalis. The degree of antimicrobial activity of catechins were different among microorganisms; that is 2 mg/mL to Leuconostoc mesenteroides, Lactobacillus plantarum, and Pediococcus cerevisiae, 4 mg/mL to Streptococcus faecalis, and 5 mg/mL to Lactobacillus brevis; however, Saccharomyces cerevisiae can not be inhibited. The effect of tea catechins on retardation of kimchi fermentation was tested by measuring changes in pH and acidity. The changes of pH and acidity of baechu-kimchi and mul-kimchi were remarkably inhibited by adding the tea catechins at the level of 2 mg/g fresh baechu. These results suggest that the tea catechins can be successfully used for the extension of shelf-life of kimchi.

This study was performed to investigate the effect of kimchi intake on antiaging characteristics in liver of senescence-accelerated mouse (SAM) in terms of free radical production and anti-oxidative enzyme activities. Two hundred twenty SAM were divided into four groups and fed kimchi diet for 12 months. Experimental groups were kimchi free AIN-76 diet (control) group, Korean cabbage kimchi diet (KCK) group, mustard leaf added (30%) Korean cabbage kimchi diet (MKCK) group, and mustard leaf kimchi diet (MLK) group. Amount of freez-dried kimchi added to the diet was 5% that is equivalent to 50 g of fresh kimchi. Concentrations of total free radical, OH radical, $H_2O$$_2$in the liver significantly increased as aged (p<0.05). But those free radical concentrations from kimchi diet groups were lower than those of control (p<0.05). Among kimchi groups, MKCK and MLK groues showed greater inhibiting effect than KCK. Antioxidant enzyme activities of Cu, Zn-SOD, Mn-SOD, GSH-px, catalase and GSH/GSSG in kimchi groups were significantly increased (P
