This study analyzed Kimchi eating culture in 178 households with female middle school children located in Incheon and Seosan areas, investigated the Kimchi eating patterns of female middle school students, and also analyzed the differences in value recognition for Kimchi between mothers and their female middle school students. Results showed that 23.0% of subject households answered eat Kimchi at every meal and the main reason for eating Kimchi in most households was good for taste. Most households made their own Kimchi, and only 12.3% of households bought Kimchi. Subject households preferred hot and spicy taste (34.8%) and pleasing taste (20.2%), and 44.4% of middle school children answered as eating Kimchi at every meal, and the source for information on Kimchi was home in 51.6% and mass media in 33.7%, suggesting the lack of school education. Both mothers and their female middle school students placed high value on Kimchi for its nutritional aspect and on Kimchi from the market for its convenience. Mothers showed significantly higher value (p<0.05) on the storage aspect of Kimchi compared to their middle school students, and female middle school students showed significantly higher value (p<0.05) on the value recognition for Kimchi as an international food compared to their mothers. Also, the value for hot pepper powder was high among other additional ingredients, and both mothers and middle school students had high values for Kimchi stew among other food dishes using Kimchi, and middle school students showed higher values (p<0.001) on foreign dishes using Kimchi such as Kimchi pizza and Kimchi spaghetti compared to the mothers group. Therefore, based on these results, the development of educational programs on Kimchi is needed not only at home but also at schools, by re-emphasizing the importance of value recognition for Klmchi in our food culture.

The purpose of this study was to investigate the knowledge and perception for Kimchi in middle school students. A questionnaire was used as the instrument of investigation. The subjects were 375 male students and 278 female students in Masan and Changwon City. The main results of this study are as follows. Ninety-three point three percent of the subjects were nuclear family type and 61.7% of respondent's mother had job. The average knowledge score for Kimchi of the subjects was 5.27 out of possible 10 points and the average value score on Kimchi was 41.25 out of 50 points. Eighty-six point one percent of students think they should eat Kimchi because Kimchi is good for the health(38.6%) and Kimchi is our traditional food(31.4%), and it was significantly difference between gender(p<0.01), male students more realized 'Kimchi is good for the health(41.6%)', whereas female students more realized 'Kimchi is our traditional food(38.9%)'. The subjects perceived that the additive material making for Kimchi were powdered red pepper(80.2%), garlic(62.5%), salt(62.0%), salted, fermented shrimp(50.2%). ginger(49.5%), green onion(39.8%), salted, fermented anchovy(34.9%), sesame(25.0%), carrot(22.4%). More than 70% of the subjects estimated for Kimchi 'Kimchi is our traditional food(84.1%)', 'Kimchi must be developed the international food'(73.7%), 'Kimchi must be in succession(75.8%)', 'Kimchi is very nutritious food(70.3%)'. However, they thought Kimchi have to be improved more hygienically(38.8%) and less stimulative taste(25.7%). The knowledge for Kimchi showed a positive correlation with the value on Kimchi and the preferences for Kimchi, and the value on Kimchi was a positively related to the preferences for Kimchi(p<0.01). Therefore it is need to the development of program for the knowledge for Kimchi and the value on Kimchi in order to improvement the preferences for Kimchi.

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.

For quality standardization, the application of functional lactic acid bacteria (LAB) as starter cultures for food fermentation is a well-known method in the fermented food industry. This study assessed the effect of adding a non-thermally microbial inactivated starter culture to kimchi, a traditional Korean food, in standardizing its quality. In this study, pretreatment based on sterilization processes, namely, slightly acidic electrolyzed water (SAEW) disinfection and ultraviolet C light-emitting diode (UVC-LED) of raw and subsidiary kimchi materials were used to reduce the initial microorganisms in them, thereby increasing the efficiency and value of the kimchi LAB starter during fermentation. Pretreatment sterilization effectively suppressed microorganisms that threatened the sanitary value and quality of kimchi. In addition, pretreatment based on sterilization effectively reduced the number of initial microbial colonies in kimchi, creating an environment in which kimchi LAB starters could settle or dominate, compared to non-sterilized kimchi. These differences in the initial microbial composition following the sterilization process and the addition of kimchi LAB starters led to differences in the metabolites that positively affect the taste and flavor of kimchi. The combined processing technology used in our study, that is, pre-sterilization and LAB addition, may be a powerful approach for kimchi quality standardization.

In the present study, kohlrabi-kimchi was prepared for assessment of changes in sensory qualities and measurement of changes in quality characteristics according to the storage period for the purpose of using kohlrabi as an ingredient of Kimchi. Examination of the physicochemical properties of kohlrabi-kimchi according to the storage period showed that the acidity increased steadily throughout the storage period, while soluble-solids content, pH and hardness decreased as the storage period elapsed. Meanwhile, the L value increased and then it decreased as the storage period elapsed, but, the a value increased and the b value gradually decreased after day 14 of storage. Reducing sugars increased up to day 10 of storage, and then they decreased slowly after day 15 of storage. Measurement of changes in lactic acid bacteria in kohlrabi-kimchi according to the storage period showed bacterial growth showing typical tendencies of Kimchi with a rapid increase on day 5 of storage and a decrease thereafter. Assessment of sensory qualities of kohlrabi-kimchi according to the storage period showed that the highest scores for appearance and sourness, odor, texture, and overall scores were obtained on day 15 of storage. Based on the above results, it was determined that the optimal maturity period of kohlrabi-kimchi is day 15 of storage.

This study was conducted to investigate the effect of blanching on the quality characteristics of dandelion Kimchi. Experimental groups were divided BT-group (dandelion was blanched in the $3\%$ brine for 15 seconds at $100^{\circ}C$, then salted in $8\%$ brine for 5 hours) and NT-group (dandelion was salted at $8\%$ brine for 5 hours). Changes in pH, acidity, color, number of total microbe and lactic acid bacteria, antioxidant activity and sensory quality were investigated during the fermentation at $10^{\circ}C$. The pH of the BT- and NT-Kimchi maintained higher than 4.1 for 21-days fermentation, but that of BT-Kimchi was lower than that of NT-Kimchi. And also, the titrable acidity of BT-Kimchi was maintained higher than that of NT-Kimchi. $L^\ast\;value\;and\;b^\ast$ value of BT-Kimchi were higher, while $a^\ast$ value of BT-Kimchi was lower than that of NT-Kimchi. There was no significantly difference in total microbial count between BT- and NT-Kimchi, while number of the lactic acid bacteria in the BT-Kimchi was higher than that of BT-Kimchi. There was no significant difference in the antioxidant activity between BT- and NT-group during the fermentation. In the results of sensory evaluation of the dandelion Kimchi, toughness, color, flavor and overall quality were good in the BT-Kimchi, while the bitter taste showed relatively strong in the NT-Kimchi.

This study was conducted to evaluate the degree of value assigned to traditional Korean foods by residents from the Kyunggi(n=582) and Kangwon(n=189) areas of Korea. We determined the degree of value for 13 items classified as traditional Korean foods by asking subjects to score the items based on a 5 point Likert scale. Based on the total scores, resident in Kyunggi assigned Kimchi the high degree of value. Next was Tteok, then Eum-cheong, Jang, Hankwa, Muk, Bap, Jeon, Namul, and Guk, respectively. In the Kangwon area, the total scores showed that Kimchi also had the highest degree of value, followed by Tteok, Jang, Hankwa, Eum-Cheong, Muk, Bap, Namul, Jeon and Myeon, respectively. The female residents in Kyunggi gave Kimchi a higher degree of value than the male residents'. Also, subjects with overall higher positive perception of traditional foods had a higher degree of value for Kimchi. Relative to age, ther was a trend showing older subjects had a higher degree of value for Kimchi than Younger subjects. In the case of the head of the family, residents of the Kangwon area showed a trend toward a high degree of value for Kimchi. The residents in Kyunggi, compared to the residents in Kangwon, evaluated the Jang food group as inexpensive foods(p<0.05). However, there was no significant difference between the residence areas for the total score of the items. Overall, the resident's evaluation of the degree of value traditional Korean foods increased with increasing age.

Antioxidative effects of crude chlorophylls and carotenoids extracts from mustard leaf kimchi on the lipid peroxidation in rat liver homogenate, egg phosphatidyl choline (EPC) liposome and superoxide anion radical were examined. The extracts were found to inhibit the increase of the thiobarbituric acid (TBA) value and show the effect of antioxidative activity on the liposomal phospholipid membrane. The oxidation index of EPC liposome was markedly decreased in the prescence of the extracts. The antioxidative activity of the extracts from mustard leaf kimchi was not related with fermentation period of the kimchi. The extracts from mustard leaf showed the similar antioxidative activity of $\alpha$-tocopherol within in the given level of addition. However, the oxidation index. When the effect of the extracts from mustard leaf kimchi on free radical scavenging was observed by the determination of the superoxide anion radical scavenging activity, it had similar value to that of $\alpha$-tocopherol.
