  • This study examined elementary school students' perceptions and acceptances related to kimchi in Jecheon area. This study examined with 388 elementary school students. Demographic characteristics of subjects, perceptions and acceptances related to kimchi were surveyed by self-developed questionnaires. Exactly 54.1% of subjects ate kimchi more than once per day, whereas 2.8% of subjects never ate kimchi. With regard to location, the home showed the highest percentage. Exactly 94.3% of respondents answered that eating kimchi was good for health. For acceptance, 86.9% of respondents answered that they liked kimchi. Reasons for liking kimchi were texture and special taste in order, whereas the most common reason for disliking was spicy taste. Baechu-kimchi (Chinese cabbage kimchi) was highly preferred, whereas pa-kimchi (green onion kimchi) was not. Subjects with an extended family preferred oisobagi (cucumber kimchi). There were significant differences between the groups with balanced dietary habits and unbalanced dietary habits in terms of acceptance for chonggak-kimchi (small radish kimchi), yeolmu-kimchi, kkadugi, mulkimchi (watery kimchi) and oisobagi. Elementary school students in Jecheon area recognized the importance and necessity of kimchi in Korean meals. Exactly 23.7% answered spicy taste as the reason for liking reason while 37.3% answered spicy taste as the reason for disliking. These results suggest that various kinds of kimchi need to be developed for elementary students with different levels of spiciness in addition to continuous nutrition education about balanced dietary behaviors at school and home.

  • Potato kimchi, fermentation was carried out at $10^{\circ}$C for 15 days using various ratios of potato to kimchi (2.5%, 5%, 10%). The samples were determined according to the fermentation time, pH, acidity and growth of lactic acid bacteria in potato kimchi. The addition ratio of potato to kimchi had little effect on the pH, acidity or growth of lactic acid bacteria in potato kimchi. In comparison to baechu kimchi and mul-kimchi, the pH, acidity and growth of lactic acid bacteria was better in potato kimchi than in the other kimchi samples. The in vitro anticancer effect of potato kimchi was investigated using human cancer cells, AGS human gastric adenocarcinoma cells and HT-29 human colon adenocarcinoma cells. MTT assay revealed that the methanol extract of potato kimchi showed the highest anticarcinogenic effects.

  • This study is conducted to investigate to the consumption pattern of Kimchi and perception about the functional Kimchi of consumer. The survey was done between October 1 to October 15, 2011 among 294 male and female adults aged 19 and over in Seoul and Gyeonggi-do areas. The gender distribution of subjects was 33.3% males and 66.7% females. 64.3% of subjects prepared Kimchi by themselves, 23.5% of subjects received Kimchi from relatives and 12.2% of subjects purchased Kimchi from the market. In addition, the rate of preparing Kimchi at home is highest in those aged fifty or over. Only 41.8% of subjects knew how to make Kimchi. 72.1% of subjects responded that they ate Kimchi one or more a day. 46.6% of subjects have purchased commercial Chinese cabbage Kimchi. The amount of one-time purchase of commercial Kimchi were investigated; 45.2% of subjects have been buying 500-1 kg, 34.4% of the subjects bought less than 500 g, and 11.2% of subjects bought 1-3 kg. 28.2% of subjects buy Kimchi at the supermarket and warehouse market. With regard to the evaluation of Kimchi taste, most consumers were not satisfied with the sweetness of Kimchi. In this result, the perception about functional Kimchi was very low. Consumer's demands were as follows: nutrient enhancement, strengthening of biologically active substances, lactic acid bacteria enhancement in order. Small sales units were preferred by the consumers, and complementation of sweetness of kimchi was required. Various Kimchi including functional Kimchi must be developed to meet the needs of consumers.

  • This study was conducted to provide basic data on the amount of sodium and the setting of permissible error range of actual measurement, which is a problem for cabbage kimchi nutrients subject to labeling. The sample targeted was baechu (Kimchi cabbage) kimchi, which might have a large variation in sodium content by part of kimchi. Kimchi samples were collected twice from eight companies by season (spring, summer, fall, and winter). The average sodium content in kimchi samples was 619±87 mg/100 g (range, 534±63 mg/100 g to 783±40 mg/100 g). The error in average annual sodium content of abandonment kimchi (maximum value difference compared to the minimum value) was 26.8 to 64.3%. Sodium contents in kimchi produced in spring and summer were relatively low. However, deviation between individuals was large. It was found that cases exceeding the permissible error (120%) standard varied depending on the criteria for setting the amount of sodium. In addition, due to seasonal differences, sodium content in kimchi exceeded 120% of the labeling value. Thus, it is necessary to set standards suitable for characteristics of kimchi to prevent unintentional violations of labeling standards by raw materials and manufacturing processes.

  • Baek-kimchi (whitish baechu kimchi) was evaluated for anti-obesity properties and effects on triglyceride (TG) and cholesterol in blood and adipose tissues in rats fed a high fat (20 %) diet, and compared to the similar effects of baechu kimchi. Baek-kimchi does not use red pepper powder but contains higher levels of sliced radish and pear than baechu kimchi. SD rats were raised for four weeks on either a normal diet (ND, based on the AIN-93M diet), high fat diet (HFD, supplemented with 16% lard oil in the ND), or HFD containing 5 % baek-kimchi or 5 % baechu kimchi. Feed consumption was not different among the groups, but weight gains were significantly lower in the groups fed either the normal diet or HFD with baek-kimchi or baechu kimchi diets than the group fed HFD alone. The weights of liver and epididymal and perirenal fat pads in baek-kimchi and baechu kimchi diet groups were lower than those of the HFD groups, but the baek-kimchi diet group had lower epididymal and perirenal fat pad weights than the baechu kimchi diet group (p<0.05). The baechu kimchi dietary group also had significantly lower triglyceride and cholesterol contents in liver and epididymal and perirenal fat, reversing the higher levels seen in HFD. Baek-kimchi and baechu kimchi diets were also effective in lowering serum triglyceride and cholesterol levels (p<0.05). These results suggest that baek-kimchi and baechu kimchi consumption can reverse the effects of HFD on weight gain and blood and tissue lipids, and that baek-kimchi is more effective than baechu kimchi. The greater effect is probably due to the higher content of radish and pear used in baek-kimchi.
