  • In order to obtain basic data for the development of Gat-Kimchi, a salted and fermented lear mustard, changes in mineral, pigment, texture, sensory score and microflora during fermentation at 5$\pm$2$^{\circ}C$ were investigated. Changes in mineral, including iron, calcium and potassium were obviously shown and their contents were markedly decreased after 14 days of fermentation. Contents of total chlorophyll and carotenoid were slowly decreased after 6 and 10 days of fermentation, respectively and ratios of chlorophyll a/b were not changed and similar to those of other cruciferous vegetable Kimchi during fermentation. Shear force of Gat-Kimchi in rheometer during fermentation was increased. The sourness and hardness(p<0.05) of Gat-Kimchi after 24 days of fermentation were significant different in sensory evaluation with no significant difference in off-flavor, color and hotness. Compared with other Kimchi, taste of Gat-Kimchi was desirably kept for 54 days of fermentation. Total viable count and lactic acid bcateria(Genus Lactobacillus) observed to be Increased in the range of 18 to 24 days and yeasts to be gradually increased during overall period of fermentation.

  • In this study, the quality characteristics and storage properties of gat kimchi added with oyster shell powder and Salicornia herbacea powder were investigated during a storage time of 80 days at $5^{\circ}C$. After storage for 80 days, the average calcium contents were significantly higher in the kimchi containing the oyster shell powder and Salicornia herbacea powder than the control. In addition, the average hardness value was significantly higher in the OS4 group(oyster shell powder at 4% and Salicornia herbacea powder at 2%) than the control group, as well as the OS10 group(oyster shell powder at 10% and Salicornia herbacea powder at 2%) during storage for 80 days. The hunter b value of the OS4 group was significantly lower than the control group. During fermentation, gat kimchi containing the oyster shell powder and Salicornia herbacea powder had a higher pH and a lower acidity value than the control group. In terms of sensory evaluation, there were no significant differences between the control and calcium-added kimchi during fermentation. After 40 days of storage, the OS4 group showed a lower total viable count, as well as lower lactic acid bacteria, yeast and E. coli, as compared with the control and OS10 groups. Based on the microbial load, the gat kimchi containing the oyster shell powder showed limitations in terms of shelf life.

  • A survey of the notion and intake on Kimchi among college women in Pusan was conducted to get some basic information on kimchi. Two hundred sixty seven students in Pusan participated in this survey. Seventy five percent of students answered that they like kimchi. They preferred well-fermented kimchi with anchovy extracts, refreshing taste and crispy texture the saltly and sweet. Chinese cabbage kimchi (87.6%) was found to be the most favored kimchi and Kakdugi(seasoned pickles of cubed radish), Nabak kimchi and Chonggak kimchi (ponytail kimchi) were followed in the order. The most favorite food made from kimchi was stir fried kimchi with rice. They disliked traditional special kimchi, such as Puchu kimchi (leek kimchi), Pa kimchi (green onion kimchi), Kkennip kimchi (perilla leaf kimchi), Godulbaegi kimch (Korea wild lettuce kimchi) and Gat kimchi (Leaf mustard kimchi). About 93 grams of kimchi was consumed daily and this amount was a little. Seventy percent of students did not have any experiences preparing kimchi. Experiences of kimchi preparation were given by mother through kimchii-making event for the winter(71.7%), cooking practice in middle or high school (14.1%) and college(10.9%) and general cooking education (33%). They preferred to buy kimchi at the Agricultural Cooperative Association (48.5%) or a large kimch factory (32.75). College students believe that kimchi is a healthy food and are willing to learn how to make kimchi.

  • In this study, quality characteristics of three different kinds of Gat Kimchi, added with Cheonnyuncho fruit (C-fruit) water extract, Cheonnyuncho cladodes (C-cladodes) water extract, and without Cheonnyuncho water extract (control group), were investigated during storage for 80 days at $5{\pm}1^{\circ}C$. In terms of mineral content of Gat Kimchi, C-fruit group showed higher calcium and zinc contents than the control group, whereas Cheonnyuncho groups showed higher iron content, and C-cladodes showed higher potassium content than the control group. The pH was mostly higher in Cheonnyuncho groups than in the control group until 40 days of storage, whereas the pH of the C-cladodes group significantly decreased after 60 days. On the other hand, titratable acidity showed the reverse tendency during storage. Hunter's color L, a, and b values all increased during the storage period. The hardness value was significantly higher in Cheonnyuncho groups than in the control group after 40 days of storage, and hardness value of the C-fruit group was significantly higher than those of the other groups after 80 days of storage. In terms of sensory evaluation, there was no significant difference between the control group and Cheonnyuncho group during fermentation. As a result, the study suggests that addition of C-fruit extracts increase nutrition and function of Gat Kimchi during storage.

  • To increase the marketability of Dolsan leaf mustard Kimchi, seasonings were prepared by sea tangle and Lentinus edodes. Gat Kimchi A (GK-A) and Gat Kimchi B (GK-B) were prepared by addition of complex seasoning with Sea tangle (CSS), complex seasoning with Lentinus edodes (CSL), respectively and evaluated the quality characteristics. GK-A contained high minerals and dietary fiber and showed the effect of delaying pH-lowering and acidity-rising. There were no significant differences in salinity test after 70 days. Reducing sugar of test groups was higher than control. During the fermentation, Leuconostoc sp. was grown in GK-A and GK-B than control. Growth of control's Lactobacillus sp. increased 20 days after. Up to 30 days, lightness of control was high. Yellowness were increased browning potential in GK-B, 20 days after. From the initial to 10 days, Hardness of GK-A showed higher than the others. glutamic acid and aspartic acid content of GK-A was higher significantly than the others in the entire fermentation period (p<0.05). At 0, 10, 30 days, sweet-tasty amino acids of GK-A showed a significantly higher level than the others (p<0.05). From 10 days to 40 days of fermentation, the sensory evaluation of GK-A is better than the other groups. Comprehensively reviewed the above results, the conclusion is as follows: CSS made with sea tangle as a main ingredient. GK-A by seasoning the CSS to 90 g GK-A is expected as a new Dolsan leaf mustard products that can provide flavor and nutrition to the consumer at the same time.
