The studies were carried out to investigate antimicrobial activity of mixed extracts of Lithospermum erythrorhizon and Scutellaria baicalensis G. and crab shell against lactic acid bacteria isolated from kimchi. The effects of Lithospermum erythrorhizon and Scutellaria baicalensis G. extracts and crab shell on shelf life of kimchi were also investigated. The growth of heterofermentative and homofer mentative lactic acid bacteria was inhibited by 95% ethanol extracts of Lithospermum erythrorhizon and Scutellaria baicalensis G. The pH of kimchi containing 1% of mixed extracts Lithospermum erythrorhizon. and Scutellaria baicalensis G., and crab shell was lower than control during fermentation for 25 days of 10oC. The viable cells of the kimchi samples were lower than that of control during fermentation. The sensory qualities of the kimchi samples were a little inferior to the control during shelf life of kimchi.

Quality characteristics of baechu (Kimchi cabbage) kimchi prepared using various kinds of domestic solar salts (KS5Y, KS2Y, KS1Y, KFS, and KSS) and imported solar salts (AS1Y and CS1Y) were compared with Korean processed salt (KRS) and Mexican rock salt (MR1Y) during 60 days of storage. Sodium contents of MR1Y, AS1Y, and domestic KRS with values of 363,653.40, 358,952.40, and 356,799.90 mg/dL, respectively, were significantly higher than that of KFS with a value of 280,249.80 mg/dL (p < 0.001). Thus, the kimchi using KFS was expected to have 22-23% lower sodium content compared to that of the other kimchis. KFS magnesium content was significantly highest at 4,464.10 mg/dL and calcium was significantly the highest in samples of KS1Y with a value of 711.31 mg/dL. Most of the pHs and acidities in the kimchi samples were in the optimum range due to the relatively low storage temperature of $2^{\circ}C$. The salt concentrations of all kimchis using domestic solar salt during storage was greatly reduced compared to those using the imported salts or KRS. Sensory saltiness of the KS1Y sample group was significantly the lowest value (6.08) at 0 days of storage (p < 0.001) and maintained relatively low saltiness during the entire storage period. The crispness of the KS2Y, KS1Y, and KSS sample groups were significantly higher (10.02, 9.77, and 9.49, respectively), compared to that of KRS (7.64) at 60 days of storage (p < 0.001). The KFS sample group had the higher acceptance values for pickled seafood aroma, sour aroma, saltiness, and overall acceptability compared to those in the other samples.

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.

The purposes of this study are to investigate American university students′responses to Kimchi and their preference on different kinds of Kimchi as indicated by a survey and sensory evaluation and to globalize Kimchi. About 400 Indiana University students in IN, USA participated in perception survey of Kimchi, which consisted of 64.8% of male and 35.2% of female.37.3% of all the participants knew what Kimchi was and 30.3% had eaten Kimchi before the survey. The students′responses to the 12 questions about Kimchi were measured on 5 point Likert scale. The item "Kimchi is nutritious and healthy" was totally received the highest point and "Kimchi is a good side with beer or wine" roamed the lowest. Furthermore, gender and the precious visitation to Korea laid an important part in the experiment. As the result of sensory evaluation, the American students preferred Kimchi that made out of soaking Baechu for 3 hours to 5 hours. When the Kimchi was fermented at room temperature(20~22$^{\circ}C$), the score decreased as the fermentation period was increased. However, the scores for the Kimchi preserved in the refrigeratior(5~1$0^{\circ}C$) did not vary remarkably. And the most preferred Kimchi by the students was one-day old. The dishes using Kimchi as the main ingredient are lifted according to the students preference as follows : Kimchi Ramen, Kimchi Mandu, Kimchi Hamburger, and Kimchi Bokumbap, and so on.

In this study, we investigated quality and fermentation characteristics in baechu kimchi containing 0(control), 5(GK5), 10(GK10), 15(GK15) and 20(GK20)% of shred garlic. Analysis was performed during fermentation at $4^{\circ}C$ for 42 days, every 7 days. The result showed significant changes in color value between control group and garlic added groups. Hunter's color L value was increased during fermentation whereas a and b value were decreased. Hardness of kimchi was higher in 15% and 20% garlic added groups than other groups. The pH decreased significantly during fermentation, while titratable acidity was showed reverse tendency during fermentation period. The reducing sugar content was decreased in all groups during fermentation period, which higher in GK10 and GK15 group than the others. But its remaining ratio was 19.7~22.3% and not showed significant difference in experimental groups at 42 days fermentation. The number of lactic acid bacteria was dramatically increased up to 6.13~7.60 log CFU/g at 7~14 days fermentation. The garlic was inhibited significantly the growth of lactic acid bacteria, but this was not showed significant difference between garlic added groups and control group, after 28 days fermentation. As a results, we suggest that addition of garlic increase the quality characteristics and storage properties of Kimchi, and not hinder quality of kimchi at addition level of 20% than salted baechu.

This study investigated elementary school students' perception, preferences, and intake of Korean traditional foods, focusing specifically on kimchi, tteok (rice cake), and eumcheong (beverage) varieties; and compared them by gender, living with grandparents, mother's occupation, and meal preparation by the grandmother. The subjects were 287 6th grade elementary school students in Busan. The results were as follows: 80% of children were interested in Korean traditional foods. 40% believed that their intake of Korean traditional foods was decreasing because these foods were not palatable to them. The majority of them, however, said they would continue to eat Korean traditional foods as they had done (54.7%) or eat more than before (36.6%) in the future. The children thought that Korean traditional foods were rich in nutrition and good for their health. The children had the highest preference for Baechu-kimchi among varieties of kimchi, and they had high preferences for Songpyeon, Galaitteok, and Injulmi. They had high preferences for Sikhye, citron tea, and adlai tea. Over 80% reported consuming Baechu-kimchi and Kkakdugi three to four times per week. They had eaten Injulmi the most frequently among the tteoks, while over 80% had eaten the other types of tteok only once or twice per month. Adlai tea, citron tea, and Sikhye were drunk more than once per week. In general, we noted no significant differences in the children's perceptions, preferences, and intake of Korean traditional foods by gender, living with grandparents, mother's occupation, and meal preparation by grandmother, with the exception of several items. The students had a very positive perception of Korean traditional foods. They had higher preferences for and had more frequently consumed the more familiar Korean traditional foods. It is therefore suggested that if the children had opportunities to experience Korean traditional foods more frequently and variously at home or in restaurants, they would appreciate Korean traditional foods even more, and develop higher preferences for these foods.

Recently, the consumption of commercial kimchi in Korea has increased over 30% and continues to grow rapidly. Similarly, over 50% of Japanese pickles(Tsukemono) have changed to kimchi and most of them are commerical. The purpose of this research is to cmopare and contrast Korean commerical kimchi to Japanese commerical kimchi. Furthermore, it is to provide valuable information to the consumers and suppliers as well as to improve the quality of commercial kimchi. Five different kinds of materials were used; (A) and (B) kimchi that were made and sold in Korea, (C) and (D) kimchi that were made and sold in Japan, and (E) kimchi made in Korea, but sold in Japan. The kimchi purchased on April 20th, 2002 and sensory evaluation, respectively, and they were preserved at $5^{\circ}C$. For the quality index, the followings contents were measured; moisture, ash, protein, crude lipid, mineral and capsaicin. In addition, pH, acidity and sensory evaluation for kimchi stored at $5^{\circ}C$ were measured for four weeks.
