  • The effect of red pepper powder (RPP) or kimchi on body weight and blood and tissue lipids was evaluated in male Sprague-Dawley rats fed a high fat diet (HFD). RPP (0.006% capsaicin) diet contained 5% RPP in HFD; the kimchi diet was 10% kimchi (50% RPP by dry weight) in HFD. Food consumption of the RPP and kimchi diet groups was not different than the normal or HFD groups, but final body weights were significantly lower than the HFD group (p <0.05) after 4 weeks on the RPP or kimchi diets. The weights of liver, epididymal fat pad and perirenal fat pad in RPP and kimchi diet groups were lower than those of the HFD group, but the rats on the kimchi diet had even lower weights than those on the RPP diet. Plasma concentrations of triglyceride and cholesterol were lowest in the kimchi diet group (p<0.05). The RPP and kimchi diet groups had lower total lipids, triglycerides and cholesterol in liver; as well as in tissue fat prods than the HFD group, with the greatest effect being in the kimchi diet group. These results suggested that RPP and kimchi consumption can reverse the effects of HFD on weight gain and blood and tissue lipids, and that kimchi does so more effectively than RPP alone.

  • This experimental study was carried out to evaluate the effects of Kimchi intake of Acanthopanacis cortex extract (APCE) supplementation on cytokine-induction and immune response in mice. To study in experiments using male Balb/c mice fed Kimchi and Kimchi of APCE supplementation (addition of 2% of total Kimchi weight) containing fed experimental diet during 2 weeks. Experimental mice were fed control diet or diet containing freeze-dried Kimchi at the level of 5%(w/w) or 5% freeze-dried Kimchi with 2% APCE supplementation. The main ingredient of Kimchi was Korean cabbage and fermentation was carried out at $4^{\circ}C$ for three weeks. Freeze-dried 2% APCE supplementation was added to Kimchi at the begining of fermentation. In order to investigate the effect of Kimchi intake of APCE supplementation (5%Kimchi-2%APCE), the following was performed; body weight, food intake, hematological parameter, serum level of mouse interleukin-4 (mlL-4) and mouse interferon-$\gamma$ (mIFN-$\gamma$ ), and, the percentage of CD3+/CD4+, CD3+/CD8+, B220+ in splenic cells. The results of final body weight, and food diet intake of two Kimchi groups were lower than those of the control group (not supplemented experimental diet). The hematology change obtained from the level of WBC (white blood cell) and platelet were not affected by feeding different dietary regiments, but the level of RBC (red blood cells) HB (hemoglobin), and spleen weight of two Kimchi groups were increased significantly than those of the control group. The serum level of IL-4 and IFN-$\gamma$ of two Kimchi groups were increased significantly than those of the control group, also enhanced the percentages of the CD3+/CD4+ and CD3+/CD8+ by 5% freeze-dried Kimchi, and 5%Kimchi-2%APCE group were 43.9 and 65.2%, and 96.0 and 208% than those of the control group, respectively. From these results, it can be concluded that Kimchi itself has an immuno-stimulatory effect and Kimchi contaning 2% APCE supplementation has the more pronounced effect in vivo system.

  • This study was conducted to estimate the drift of change for kimchi purchase, and to contribute to quality improvement of kimchi sold at markets. Questionnaries were distributed to 450 adults and 396 were statistically analyzed. The methods used to analyze the items were frequency analysis, Chi-square, t-tests and ANOVA. The highest preference for kinds of kimchi was Beachoo kimchi, while the preference for Nabak kimchi was low. In terms of the degree of ripening, most subjects preferred properly ripened kimchi. With regard to the purchase amount the subjects preferred 1 kg and mainly purchased it once every three months at large market and supermarkets. The main reason for purchasing kimchi at markets was 'convenience', while the reason they didn't purchase it was 'it might contain artificial seasoning'. With regard to the development and improvement of the kimchi industry, the subjects belived that taste and ripening should be standardized, and that kimchi should be treated sanitarily. They acknowledged that kimchi products should be diversified, and active marketing should be carried out in order for it to be globalized.

  • This study was conducted to summarize the known kinds and characteristics of traditional special kimchies in Pusan and Kyungnam province. The taste of kimchi varies from region to region within Korea. In the southern part of the country, where the weather is much warmer, more salt is added along with salted anchovy(Myulchi Jeot), and the kimchi is less juicy and richer in flavor. More than 180 different varieties of kimchi are reported in Korea, but there are 30~40 different kinds of kimchi in Pusan and Kyungnam province depending on the main ingredients are known. Puchu kimchi(leek kimchi), Uung kimchi(burdock kimchi), Kongnip kimchi(soybean leaf kimchi) are the typical traditional special kimchi in Pusna and Kyungnam province. Todays, dietary cultures has been gradually changed, and diminished the local characteristics. Also, these tendency appears in the taste of the traditional special kimchi. However, it still remains the distinciton in the taste, ingredients and the methods of preparation of kimchies of Pusan and Kyungnam province. In this paper, the dispersed informations on the kinds, characteristics, and the preparation method of the special kimchies known in literatures and inherited persons in Pusan and Kyungnam province were tried to put together.

  • We made the Toha-jeot added cabbage kimchi with Toha-jeot, which is salt-fermented Toha shrimp in Korean traditional fermented food. The physicochemical characteristics of cabbage kimchi for 5 week fermentation at 4$^{\circ}C$ were observed. The salt content was 2.10~1.50% during the fermentation period. The salt content decreased rapidly during the first week, stayed the same level until the 4 week and then decreased after the 4 week. The pH of control kimchi and Toha-jeot added cabbage kimchi were 5.69, 5,64, respectively on preparation day. The rate of decrease of pH of Toha-jeot added cabbage kimchi was slow as the fermentation processed. The total acidity of the two kinds of kimchi was increased. The total acidity was higher from Toha-jeot added cabbage kimchi than control cabbage kimchi at the later stage of fermentation. The contents of total sugar and reducing sugar were higher from Toha-jeot added cabbage kimchi than control cabbage kimchi at the early stage of fermentation. The total sugar and reducing sugar contents of the two kinds of cabbage kimchi were decreased gradually as the fermentation processed. The ascorbic acid contents of the two kinds of kimchi were decreased slightly at the early stage of fermentation and then increased from 2 to 4 week, while there was no further change at 5 week.

  • The effect of kimchi, traditional Korean fermented vegetables, on inactivating food-borne pathogens and the kimchi factors affecting the antimicrobial activity were investigated. More cells of Listeria monocytogenes, Staphylococcus aureus, Escherichia coli O157:H7, and Salmonella typhimurium were inactivated in the kimchi that had low pH and high titratable acidity. Of the raw ingredients in kimchi, raw garlic showed the strongest antimicrobial activity against the pathogens. When kimchi was fermented at 0, 4, 10, or $20^{\circ}C$ to pH 4.4, higher kimchi fermentation temperature resulted in higher titratable acidity. The greatest inactivation of S. typhimurium occurred in kimchi fermented at $20^{\circ}C$, while L. monocytogenes were inactivated in kimchi fermented at $0^{\circ}C$ in situ. This study showed that appropriately fermented kimchi can inactivate various food-borne pathogens and that the fermentation temperature of the kimchi is an important factor in determining the ability of the kimchi to inactivate specific pathogens. Lactic acid bacteria (LAB) multiplication and organic acids produced according to LAB metabolism play a role in inactivating food-borne pathogens in kimchi.

  • This study was conducted to investigate the effect of ginseng on the preservability and quality of Chinese cabbage Kimchi. The effect of ginseng on the growth of Lactobacilli, pH, titratable acidity, amount of juice, sensory quality and fracitonation of cell wall ploysaccharides, and enzyme activities related to softening were examined during fermentation. Ginseng promoted the growth of L. brevis and it didn't influence L. plantarum and L. fermentum. But Leuc. mesenteroides and P. cerevisiae was inhibited a little by adding of ginseng. The quality of ginseng added Kimchi evaluated by nalysis of the pH, acidity, sensory quality, the amount of juice, and overall eating quality during fermentation was better than those of control Kimchi, and 2% ginseng added Kimchi was the best ont the preservability and quality. The activity of β -galactosidase in ginseng added Kimchi was higher than that of control Kimchi. But the activity of polygalacturonase in ginseng added Kimchi was the same as that of control Kimchi. Ginseng added Kimchi showed more desirable softness of tissue. This was the same result as the analysis of pectic substance and hemicellulosic polysaccharides composed of cell wall polysaccharides. The value of L(lightness) of ginseng added Kimchi was highly maintained during the edible period and the yellow color from the ginseng was moved to Kimchi tissue in the ginseng added Kimchi.

  • This study aims to establish a strategy for selling kimchi to satisfy the needs and wants of European consumers through survey, FGI, and IDI. All survey participants were Europeans and were selected on the basis of their kimchi awareness. For the quantitative survey, 246 participants 15 years or older were selected; for FGI, 33 participants aged between 20 and 49 were selected; and for IDI, eight chefs were selected. The survey included four steps of 'Awareness-First try-Needs-Future consumption'. The participants got to know kimchi through the Internet; for example, by visiting Korea and Hallyu, and suggested positive comments, including 'fancy' and 'exotic.' While satisfaction with kimchi sharply decreased due to taste and appearance in the first try of kimchi, it is important to provide the best first-try experience. It also showed that important needs for kimchi are 'hot sensation', 'crunchiness' and 'presentation'. They gave a negative answer to combination with traditional cuisines of their own country, but provided positive comments for benchmarking the use of traditional pickled foods. This study suggests that it may be necessary to implement a two-track strategy by the traditional kimchi as a 'strategic product' and localized kimchi as a 'key product'.

  • To investigate the effect of the predominant microorganisms in kimchi on quality, Leuconostoc mesenteroides ATCC 8293 was used as starter culture during kimchi fermentation. A higher number of lactic acid bacteria and lower initial pH were observed in starter kimchi than in non-starter kimchi in the early stage of fermentation. The concentrations of the main metabolite, lactic acid, were 69.88 mM and 83.85 mM for the non-starter and starter fermented kimchi, respectively. The free sugar concentrations of starter kimchi decreased earlier than those of non-starter kimchi, and the levels of free sugars in both kimchi samples decreased during fermentation. At the end of fermentation, non-starter kimchi had a softer texture than starter kimchi, suggesting that L. mesenteroides is useful in extending shelf life. Sensory evaluation showed that starter kimchi had higher sourness and lower bitterness and astringency values, resulting in high sensory quality. These results suggest that the L. mesenteroides ATCC 8293 strain could be a potential starter culture in kimchi.
