  • 돌산 갓(Brassica juncea) 김치 개발의 일환으로 갓 김치 숙성 중의 휘발성 성분을 분리, 동정하였으며, 매운 맛 성분인 glucosinolate의 함량변화를 분석하였다. 돌산 갓 김치의 숙성 중의 주요 휘발성 성분은 3-isothi-ocyanate-1-propene(Allyl isothiocyanate)이었으며, 그 외 di-2-propenyl disulfide, 1-methoxy1-2-butanol, 4-isothiocyanate-1-butene, di-2-propenyl disulfide 그리고 dimethyl-trisulfied 등 이었다. 갓 김치가 발효됨에 따라 AITC와 4-isothiocyanate-1-butene은 점차 감소하였지만, dimethyl trisulfide는 발효 저장 중에 다소 증가 하였다. Di-2-propenyl disulfide는 5일 까지 감소되었다가 10일 이후에는 다소 증가하였다. 갓 김치 숙성 중의 매운맛 성분인 총 glucosinolate 함량은 3일 까지 증가하다가, 그 이후는 감소하는 경향을 보였다.

  • To enhance the antitumor activity of Chinese cabbage kimchi, four kinds of kimchi, which ere differently prepared in kinds and levels of sub-ingredients, were fermented at 15$^{\circ}C$ for 1 day and then at 5$^{\circ}C$ up to pH 4.3. The solid tumor formation, hepatic glutathione S-transferase activity and glutathione contents in the liver, and natural killer (NK) cell activity of spleen were determined from the sarcoma-180 cell injected Balb/c mice that were treated with methanol extracts of the kimchi samples. Kimchi IV, prepared with organically cultivated Chinese cabbage, red pepper powder, garlic, Chinese pepper powder mustard leaf and heat processed salt (Gueun salt), reduced the tumor formation by 39.3% compared to the sarcoma-180 cell treated group, resulting in the smallest tumor weight. Methanol extracts of the kimchi III and kimchi IV recovered the activities of hepatic glutathione S-transferase(GST) that was decreased by the transplantation of the sarcoma-180 cells to th mice. The injections of methanol extracts of kimchi II and kimchi IV increased glutathione contents in sarcoma-180 cells treated mice. The methanol extract of kimchi IV increased the natural killer (NK) cell activity of spleen lymphocytes a more effectively (p<0.05) than those the other kimchi samples. These results suggest that the anticancer activities of kimchi can be increased by changing the kinds and levels of sub-ingredients.

  • To determine the salinity of packaged Kimchi, bulk Kimchi and other common foods, we collected samples of foods from the Gyeonggi province area in October 2006 and determined the salinity levels in one serving portion. The average salinity of all foods was 0.226${\pm}$0.212%. The average salinity of all Kimchi samples was 0.401${\pm}$0.260. The average salinities of soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.153${\pm}$0.085%, 0.691${\pm}$0.213%, 0.151${\pm}$0.102%, 0.209${\pm}$0.121% and 0.080${\pm}$0.016%, respectively. The average salt intake of one serving of Kimchi was 0.125${\pm}$0.041 g, while the average salt intakes of one serving of the soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.306${\pm}$0.170 g, 1.382${\pm}$0.426 g, 0.094${\pm}$0.061 g, 0.146${\pm}$0.089 g, and 0.159${\pm}$0.152 g, respectively. The salinity of packaged Kimchi was significantly higher than the salinity of the bulk Kimchi (p < 0.01). In addition, the salinity of the liquid and solid stem portions of the packaged Kimchi was significantly higher than the salinity of the same sized portions of the bulk Kimehi (p<0.01). Furthermore, the salinity in the liquid and solid stern portions of the packaged mustard leaf Kimchi were significantly higher than the salinities of other types of Kimchi (p < 0.0001). The salinity of all Kimchi is higher than that of soup, protein containing side dishes, vegetable side dishes or drinks, but the salt content of one serving of Kimchi is lower than those of the soups or stews or vegetable side dishes or drinks (because one serving size of Kimchi is usually smaller than that of the other foods).

  • To improve Dongchimi (watery radish kimchi) quality and preservation, 0, 3, 5, 10, and 15% of gatt (Brassica juncea; leaf mustard) per radish was added. Chemical characteristics were determined during fermentation at $10^{\circ}C$ for 45 days. Total acidity increased slowly by addition of gatt during initial fermentation period, and 15% treatment showed lowest total acidity. Total vitamin C content increased initially in all treatments depending on gatt content, and decreased thereafter. Period for reaching maximum value was delayed by addition of gatt. Highest total vitamin C was found in 15% treatments. In the case of reducing sugar, 5% treatment showed highest contents. Lactic, succinic, and tartaric acid contents consistently increased during fermentation, while those of malic and citric decreased. Turbidity and total solid contents of Dongchimi liquid increased in all treatments as fermentation proceeded, although the extent was rather suppressed by addition of gatt. Colorimetric lightness values decreased, while the initial increased and then decreased in redness and yellowness. Addition of gatt at above 15% weight level per radish accelerated fermentation at the later fermentation stage thus it should be avoided. Most changes in typical characteristics of fermentation were similar depending on treatments. More acceptable Dongchimi could be prepared by fermenting at 5% gatt concentration under given conditions.

  • The purpose of this study was to measure the factor influencing tourist preferences for leaf mustard iimchi. Among 250 questionnaires, 230 questionnaires were utilized for the analysis. Frequencies, conjoint model, max. utility model, BTL model, Logit model, K-means cluster analysis, and one-way ANOVA analysis were used for this study. The findings from this study were as follows. First, the Pearson's R and Kendall's tau statistics showed that the model fitted the data well. Second, it was found that total respondents and three clusters regarded taste and price as the very important factor. Third, it was found that the first cluster most preferred product with light red color, plain package, and mild taste sold at a cheap price in factory. The second cluster most preferred product with light red color, plain package, and moderately pungent taste sold at a expensive price in factory. The third cluster most preferred product with dark red color, shaped package, and highly pungent taste sold at a cheap price in factory. Fourth, it was found that the first cluster most preferred simulation product with light red color, shaped package, and mild taste sold at a cheap price in factory. The second cluster most preferred simulation product with light red color, shaped package, and moderately pungent taste sold at a cheap price in factory. The third clutter most preferred simulation product with dark red color, shaped package, and highly pungent taste sold at a cheap price in factory.

  • Methanol extracts form four kinds of kimchi, which were differently prepared in kinds and levels of sub-ingredients, were given to Balb/c mice for 3 weeks (0.5 mg/kg/day). Peritoneal macrophages isolated from mice treated with kimchi extracts and saline were stimulated by lipopolysaccharide (LPS). K3 and K4 kimchis, containing more red pepper powder, garlic, Chinese pepper powder, mustard leaf and organically cultivated Korean cabbage, significantly increased NO production by the activated macrophages (p<0.05). K1, K2, K3 and K4 kimchi extracts (0.01, 0.1, 1.0 $\mu\textrm{g}$) significantly reduced the increased TGF-$\beta$1 production of H.pylori lysate (0.01 $\mu\textrm{g}$)-activated human epithelial RPMI 2650 cells (5$\times$10$^{4}$ cells/mL) at 24 and 48 hrs of treatment (p<0.01). However, the decreased TGF-$\beta$1 $\alpha$ production of RPMI 2650 cells by H. pylori lysate increased by treatment with kimchi extract for 72 hrs. Especially, K4 kimchi (containing organically cultivated Korean cabbage and more ingredients, modulated TGF-$\beta$1 production of H. pylori lysate-activated RPMI 2650 cells to the normal level (control) by treatment for 48 hrs. The treatment of K1 and K4 kimchi enhanced the LPS (0.01 $\mu\textrm{g}$/mL)-induced IL-6 production of splenocytes. The results suggest that kimchi might have an beneficial effect on cancer prevention due in part to the function enhancing NO production of activated macrophages. Our data suggest that kimchi could modulate TGF-$\beta$1 production by cancer cells and IL-6 production of splenocytes, thereby possibly contributing to control carcinogenesis and the immune system.

  • Starter로 사용하기 위하여 $20^{\circ}C$에서 4일간 발효된 돌산 갓김치에서 미생물을 분리하였다. 이를 starter로 접종하여 $4^{\circ}C$$10^{\circ}C$에서 50일간 발효시키면서 발효특성, 항산화활성, ACE 저해활성을 조사하였다. 1 X $10^{10}$ CFU/mL의 접종농도에서 적숙기(pH 4.5)에 도달하는 시간이 $4^{\circ}C$에서는 최고 5.6배 이상, $10^{\circ}C$에서는 5배 단축되었다. 총균수는 starter 접종농도가 높을수록 발효초부터 높은 균수를 유지하였다. 항산화활성도 starter 접종농도가 높을수록 전반적으로 골게 나타났고, 1 X $10^{10}$ CFU/mL의 접종농도에서 $4^{\circ}C$$10^{\circ}C$ 각각 최대 67%와 75%를 나타내었다. 따라서 단위 시간당 세포의 생성율($lnX_{max}$/$t_{max}$)과 항산화활성($lnX_{max}$/$t_{max}$)은 비례관계를 가지며, 초기 접종농도가 높을수록 단위 시간 당 항산화활성이 높음을 알 수 있었다. ACE 저해활성도starter의 농도가 높을수록 ACE 저해활성도 놀게 나타났다. 즉, 1 X $10^{10}$ CFU/mL의 접종농도에서 $4^{\circ}C$에서는 52%, $10^{\circ}C$에서는 최대 76%를 나타내었다. 파라서 일정시간당 체포의 생성율($lnX_{max}$/$t_{max}$)이 증가할수록 ACE 저해율 ($P_{max}$/$t_{max}$)도 증가하였으며, 초기 접종농도가 높을수록 단 위 시간당 ACE 저해율이 높았다.

  • Korean cabbage, a member of the Brassicaceae family which also includes cauliflower, mustard, radish, and turnip plants, is a crucial leafy vegetable crop. Korean cabbage is harvested after completion of the leaf heading process and is often prepared for use in "baechu kimchi", a traditional Korean food. Many of the components in Korean cabbage are essential for proper human nutrition; these components can be divided into two groups: primary metabolites, which include carbohydrates, amino acids, fatty acids, and organic acids, and secondary metabolites such as flavonoids, carotenoids, sterols, phenolic acids, alkaloids, and glucosinolates (GSLs). Using gas chromatography-mass spectrometry, this study examined the variety of volatile compounds (including isothiocyanates) contained in Korean cabbage and its seed, which resulted in the identification of 16 and 12 volatile compounds, respectively. The primary volatile compound found in the cabbage was ethyl linoleolate (~23%), while 4,5-epithiovaleronitrile (~46%) was the primary volatile component in the seed.
