  • In this study, various kind of onion herb kimchi differing in herb contents were prepared. Sensory evaluation indicated that rosemary was best of all for the tested herbs. By the sensory analysis, it seemed that 0.5% addition of fresh herb powder for onion kimchi was most preferable and 2% addition was not acceptable. Hot spice of onion was remained when kimchi was prepared but it disappeared as storage time elapsed. According to texture analysis, hardness decreased as storage time elapsed for onion kimchi without herb, but the degree was mitigated for onion herb kimchi.

  • In this study, we investigated antimutagenic and anticancer activities of leaf mustard (LM, Brassica juncea) and leaf mustard kimchi (LMK) during their fermentation period. Methanol extracts were prepared from raw mustard, brined leaf mustard in 10% Gueun salt solution for 2 hrs, leaf mustard fermented at 15$^{\circ}C$ for 5 days after brined in 10% Guenun salt solution for 2 hrs (Fr-LM), fresh leaf mustard kimchi (Fresh-LMK) and optimally ripened leaf mustard kimchi fermented at 5$^{\circ}C$ for 30 days (OR-LMK). OR-LMK showed the strongest inhibitory activities against the mutagenicities induced by aflatoxin B1 in Salmonella Typhimurium TA100. LMs and LMKs inhibited the survival or growth of AGS human gastric adenocarcinoma cells and HT-29 human colon carcinoma cells in MTT assay and growth inhibition test. Among the extracts, OR-LMK and FR-LM exhibited strong antiproliferative effect against cancer cells, especially HT-29 cells. DAPI staining assay showed that OR-LMK induced apoptosis cell death of HT-29 cells in a dose-dependent manner. These results suggest that leaf mustards and leaf mustard kimchi have chemopreventive activities.

  • To diversify usage of aquacultural red sea cucumber, new Kimchi containing red sea cucumber was developed and its quality and consumer preference were studied. The pH and total acidity, index of Kimchi ripening, decreased till 7 days of storage, then pH change became blunt and finally reached optimum pH 4-4.5. The amount of reducing sugar gradually decreased during storage period. The number of lactic acid bacteria increased in early fermentation period in both Kimchi containing boiled and fresh red sea cucumber, however, more lactic acid bacteria found in fresh red sea cucumber containing Kimchi. Preference of Kimchi containing boiled or fresh red sea cucumber compared to control Kimchi containing fermented salted fish was evaluated. The results revealed there were no differences in color, flavor, texture, taste, after taste and overall preference.

  • This study was designed to know the effect of kimchi on the hematological and immunological parameters in vivo and in vitro, respectively. To study the effects of kimchi on the hematological parameters, rats(S.D., male) were divided into 4 groups and fed diets containing of 3%, 5% and 10% kimchi or kimchi free diet(control) for 6 weeks. The results of CBC(complete blood cell) tests obtained from the bloods of rates were as follows ; In 10% kimchi group, the level of WBC(white blood cells), RBC(red blood cells), Hgb(hemoglobin), Hct(hematocrit) were increased significantly than those of control group(p<0.05). MCV(mean corpuscular volume), one of the red cell indices, was also increased significantly in the animals fed 10% kimchi(p<0.05). RDW(Red cell distritution width) and PCT(plateletcrit) was lowest in 10% kimchi group(p<0.05). To examine the effects of kimchi on immune cell growth in vitro, three types of mouse immune cells-spleen cells, bone marrow cells, thymus cells-were cultured with extracts of salted Chinese cabbage, fresh kimchi and fermented kimchi(for 1 week) for 12 or 20 days. Control was supplemented with PBS(phosphate buffer saline) excluding kimchi extract. The results of spleen cell, bone marrow cell, and thymus cell cultures showed similar tendency: control medium accelerated death of cells, extracts of salted Chinese cabbage reduced the rate of cell death, and extracts of fresh kimchi and fermented kimchi promoted cell growth. From these results, it could be suggested that kimchi possibly has an effect on the hematopoietic ability and increases immune cell development and growth in vivo.

  • This experiment was conducted to determine the effects of the pre- and post-harvest variable factors on the processed product of kimchi cabbage cultivated in semi-highland at summer time. Kimchi cabbage cultivar 'Chun Gwang' was grown in an open field and/or under a plastic greenhouse condition; it was stored at 0? after harvesting with low-density polyethylene (LDPE) film packaging. The pre-harvest characteristics growth parameters, fresh weight, head weight, no of leaves, leaf thickness, firmness, moisture content etc. were evaluated. The evaluated postharvest characteristics were fresh weight loss, appearance, trimming loss, SPAD value, moisture content and hue angle. The results show that the fresh weight and leaf thickness were higher in 'Chun Gwang' kimchi cabbages grown in the greenhouse than those in the field. However, the other evaluated factors were not affected by the type of cultural method. During the storage, the cabbage continued to decrease in fresh weight loss, trimming loss and moisture content. When compared to the kimchi cabbage showed significant difference in the fresh weight loss, trimming loss and moisture content during storage. It was confirmed that both cultural methods indoor- and outdoor did not show head growth parameters of 'Chun Gwang' kimchi cabbages on semi-high land at summer time. Although no difference in the growth before storage was observed, the evaluated characteristics like fresh weight loss etc. were influenced by cultural method as a pre-harvest factor. This study suggests that there were to be affected by pre-harvest factor during storage after harvest. In this study, an integrated management system combining relationship between processed agricultural products and their pre- and post-harvest factors.

  • A survey on the preference of kimchi and actual amounts of kimchi intake conducted from july to october 1999 to get basic information needed for the augmentation of kimchi intake. Total 1,241 of women and men aged $10{\sim}60$ in kyung-nam area participated in this survey. Except people aged $20{\sim}30$, all of subjects, especially in people aged 60 and over, liked fresh prepared kimchi best, and then fermented kimchi. But all of subjects disliked over fermented kimchi.(p<0.001) And women$(4.3{\pm}0.9)$ liked better fresh prepared kimchi than men$(4.2{\pm}1.0)$, men$(4.0{\pm}0.9)$ liked better fermented kimchi than women$(3.9{\pm}1.1)$.(p<0.05) In subjects aged above 40, as age grow up, the preference of fermented kimchi and over fermented kimchi grew lower. All of subjects best liked chinease cabbage kimchi, and then chonggak kimchi, kakdugi, yeulmu kimchi, dongchimi in order. And women liked better nabag kimchi, yeulmu kimchi, sesame leaf kimchi, bek kimchi, cucumber kimchi, godulppegi kimchi than men and men liked better chinease cabbage kimchi, kakdugi, dongchimi than women.(p<0.05) People aged $10{\sim}20$ and above 60 disliked chonggag kimchi. The preference of kakdugi were high in people aged $10{\sim}20$, but as age grow up, the preference of kakdugi became lower.(p<0.001) The preference of nabak kimchi and dongchimi with juice were significantly high in people aged 60 and over but people aged $10{\sim}20$ disliked. Also subjects aged $10{\sim}20$ disliked significantly yeulmu kimchi, sesame leaf kimchi, green onion kimchi, bek kimchi, cucumber kimchi, mustard leaf kimchi and godulppegi kimchi and subjects aged $20{\sim}30$ disliked significantly yeulmu kimchi, mustard leaf kimchi, godulppegi kimchi(p<0.001). But subject aged 30 and older liked all kinds of kimchi. The amounts of kimchi intake in Kyung-nam area were same level of average amount(100g) of korean intake but the amounts of kimchi intake of men$(106.4{\pm}74.0)$ were more than women$(96.9{\pm}69.5)$(p<0.05)

  • The effect of frozen storage on some physicochemical and sensory quality of salted Chinese cabbage and Kimchi were investigated. The texture of the fresh Chinese cabbage was preserved better by emersion quirk freezing or predrying than by air slow freezing or no predrying while no effect was measured on the salted Chinese cabbage. The salted cabbage had less frozen damages than the fresh one and had the similar texture characteristics of the fermented Kimchi. The frozen Kimchi had the similar overall quality to the unfrozen fermented Kimchi in spite of a little higher chewness values. The color of the salted Chinese cabbage was a little changed to pinkish after 3 months frozen storage but Kimchi was maintained the good quality after 6 months.

  • Effects of protein-sources on Kimchi fermentation and on the stability of ascorbic acid were investigated at $7{\pm}1^{\circ}C.$ Kimchi samples with various protein sources showed the higher pH and total acidity through the fermentation period than kimchi without the proteins. The results revealed that the proteins have acted as good buffer and lactobacilli-growth enhancer in the fermentation, and the milk proteins showed the most significant effect among the samples. The lactobacilli were at the highest growth at 15th day in all the samples. The amounts and changes in ascorbic acid content during the fermentation did not differ significantly between the control and protein added samples. The fresh, unfermented kimchi contained 14.5-15.7mg of ascorbic acid per 100g of sample and decreased continuously by the 12th day of fermentation. After then the vitamin increased in all the samples and then again decreased slowly after 18th day. The contents of ascorbic acid at the end of the 3 weeks-fermentation(16.3-17.3mg/100g) were still higher than the contents of fresh, unfermented kimchi.
