        Lactic acid bacteria from traditional Korean foods of Tarak and Kimchi was isolated and characterized against carcinogenic Helicobacter pylori. Five Tarak and 30 Kimchi, traditional lactic acid-fermented foods, were collected from Andong area and the markets in Seoul, respectively and 15 lactic acid bacteria were isolated. Among them, two isolates were selected from high growth-inhibitory activities on H. pylori. The isolates were identified as Streptococcus thermophilus LAB kw15 from Tarak and Leuconostoc mesenteroides LAB kw5 from Kimchi by the biochemical characteristics and 16S DNA sequencing. The culture solutions of the isolates adjusted to pH 7.0 showed H. pylori inhibition. The isolates grew well and H. pylori did not grow during the co-culture with those strains. Therefore, L. mesenteroides LAB kw5 and S. thermophilus LAB kw15 might be the candidates as the functional lactic acid bacteria for improving stomach health.

        Changes in major volatile odor components (VOC) and sensory properties of kimchi during ripening for 4 days were investigated, and major VOCs of the raw materials of kimchi were also analyzed. Seven of eight major VOCs of kimchi originated mainly from garlic, while one originated from ginger. During 4 days of kimchi ripening, the amount of ethanol, which was substantially higher than that of other VOCs, increased continuously but decreased slightly on the fourth day. The amount of diallyl disulfide decreased during ripening, while that of allyl mercaptan decreased on the first day and increased slightly thereafter. The amount of methyl allyl sulfide, diallyl sulfide, and methyl trisulfide increased continuously during ripening, while that of dimethyl disulfide and methyl propyl disulfide increased until the second day and decreased thereafter. Scores of overall acceptability, taste, and odor for kimchi ripened for 2 days were significantly higher than those of other samples (p<0.05). The correlation between scores of overall acceptability and the amount of dimethyl disulfide or methyl propyl disulfide was higher than that of other VOCs.

        Kimchi is the most well-known Korean traditional food, but it is also the main leftover of school lunch and dinner menus. This study aimed to familiarize teenagers with kimchi through school meals and to increase their daily kimchi intake, ultimately by appealing to the young generation's taste. A questionnaire survey was conducted in the Ansan area to examine student's acceptability of kimchi and their attitudes toward kimchi. Approximately 65% of males and 67% of female students liked the moderately fermented and pungent taste of kimchi. Kimchi served in school meals was regarded as nutritional but cheap. Approximately 72% of male and 82% of female students responded that they liked menu items using kimchi. Approximately 48% of students responded that menu items using kimchi in schools are not diverse. Students preferred meat as an ingredient in kimchi. The preferred cooking methods were stir-frying and frying, whereas boiling was the least favorite. Based on the survey results, ten kimchi menu items had been developed. The suitability of the menu was evaluated by students and cooks. Six kimchi items, including Kimchi mixed with rice, chicken, soybean sprouts, Kimchi cheese rice, stewed beef ribs with kimchi, rice topped with kimchi curry, kimchi cheese meat roast, and kimchi udong were considered appropriate for school meals, whereas kimchi kangchong, kimchi topokki, kimchi stew with surimi, and frozen Pollack kimchi soup were not suitable as menu items. Kimchi topokki was not accepted by students, while kimchi kangchong was not accepted by cooks. Cooks judged the suitability of a menu item by the cooking process and cooking times, whereas students judged an item by its sensory preference. Approximately 63% of students responded that kimchi intake has increased by participating in the development of kimchi dishes.

        Radish kimchi is a typical side-dish in Korean traditional food and is a way of keeping vegetables for a extended period using fermentation. This study examined the classification, usage, eating history, variety, and recipes of Korean radish kimchi through ancient and modern era literature. The Korean radish kimchi were categorized into six groups: kkakttugi, seokbakji (or nabakkimchi), dongchimi, jjanji, jangachi, and jangkwa. According to the record, the eating history of radish kimchi comes from before the age of the Three Kingdom period. Radish was preserved in salt, vinegar, soybean paste or lees of fermented liquor in the early times. This pickled radish was not supposed to be watery. Radish kimchi was divided into watery kimchi (dongchimi) during the period of United Silla and the Koryo Dynasty. Kimchi was mixed with Chinese cabbage to make seokbakji or nabakkimchi. Up to the early Chosun Dynasty, the key ingredient of kimchi was radish. After the middle of the Chosun Dynasty, kimchi was mixed with red pepper powder, salted fish, soybean sauce, and various ingredients. There were many kinds of radish kimchi during the late Chosun Dynasty. In the 11 Korean recipe books published within the past 100 years, there are nine kinds of kkakttugi, three kinds of seokbakji, four kinds of dongchimi, three kinds of jjanji, nine kinds of jangachi, and five kinds of jangkwa. Kkakttugi (cubed, sliced or julienne radish) was pickled with salt, red pepper powder, garlic, green onion, oyster, sugar, salted fish, and more. Seokbakji and nabakkimchi were not as salty, so they could not be preserved as long. Dongchimi (watery radish kimchi without red pepper powder) was made of radish, water, salt, 18 side ingredients, 13 condiments, and seven garnishes. Jjanji was pickled to be very salty and was eaten during summer. Jangachi can be used as a regular side dish and is made of radish or dried radish slices pickled or seasoned with salt, soy sauce, vinegar, soybean paste, lees of fermented liquor, and spices. Jangkwa is used as a stir-fry method and has been segregated from jangachi relatively recently.

        This study investigated the preference, intake condition and awareness of Kimchi of 660 elementary students in the Seoul area surveyed during June, 2008. The preference test was performed by using 5-point hedonic scale (1=dislike very much, 5=like very much). The most preferred types of Kimchi were Baechukimchi (4.32), Bossamkimchi (4.08) and Kkakdugi (4,01). The most preferred foods prepared with Kimchi were Kimchi jjige (4.59), Kimchi bokkeumbap (4.47), fried Kimchi (4.35), Kimchi pancake (4,31), Kimchi mandu (4.20) and Kimchi kimbap (4.06). Kimchi pizza (2.88), Kimchi hamburger (2.85) and Kimchi spaghetti (2.81) were not preferred. Most students (62.7%) ate Kimchi at almost every meal. The main reason for eating Kimchi was its delicious taste (50.3%). Concerning intake of Kimchi provided at school lunch, 48.4% of students ate some, 45.9% ate all and 5.8% ate none. Various kinds of Kimchi should be developed for elementary school students to meet their taste.

        Off-flavor in foods and in raw materials is quite concerning, as it could signify deeper-rooted problems. Methods of reduction of "off-flavors" in traditional food such as Cheonggukjan and Kimchi, and in raw materials of soybean paste were studied by means of a literature review. It was found that the major components of "off-flavor" were due to butyric acid, valeric acid, alkylpyrazines, ammonia, and sulfides for Cheonggukjang, and for Kimchi were sulfur containing components such as methyl allylsulfide, dimethyl disulfide, diallyl disulfide, methyl allyl trisulfide, methyl 2-propenyldisulfide, dipropenyldisulfide. There is a demand for a scientific and systematic approach in overcoming the "off-flavor" problem. Nutritional aspects and safety should be considered. Several methods have been attempted, such as masking, binding, improving cooking process, inhibiting rancidity, and controlling the growth of micro-organism. Methods of masking were the most frequently ones used for the reduction of "off-flavor", and in some cases, othertechniques were additionally applied. The masking method would be useful in the reduction of "off-flavor" in traditional Korean foods, i.e. Cheonggukjang, Kimchi, as well as in new product development.

        A survey on the quality improvement and preference for green onion kimchi by Chinese and Japanese consumers was conducted by 30 Korean specialists in order to develop an improved green onion kimchi product. The long green onion shape, kimchi juice, seasonings, off-odor of fermented sea food, and stimulatory flavor of green onion were the main issues considered for the improvement of green onion product. Usage of the favorite ingredients of the Chinese and Japanese consumers was also suggested. The percentages of Chinese and Japanese who already knew green onion kimchi were 54.1% and 30.3%, respectively, whereas 46.8% of Chinese and 28.1% of Japanese have actually tried green onion kimchi in Korea. There was no significant difference in the preference for green onion kimchi between Chinese (3.25/5.0) and Japanese (3.17/5.0) consumers. For recommendations for improving the quality of green onion, Chinese consumers thought off-flavor, fibrous texture, and fermentation level were more significant while the Japanese considered red color, various taste, MSG content, and length of green onion. Seasoned tofu with green onion and rice were suggested as complementary foods to green onion kimchi by the Chinese and Japanese, respectively.

        This study was conducted to improve the kimchi intake for high school students of various kimchi sub-ingredients and foods using kimchi. The students believed that kimchi is good for health. The overall satisfaction, baechu quality and the taste and degree of fermentation of kimchi was high, but there was a low preference for offered kimchi kinds, kimchi subingredient, foods using kimchi. The types of kimchi preferred and often offered in school meals were baechu-kimchi and kkakdugi. The common kimchi sub-ingredients were radish and welsh onion in vegetables, squid and oyster in sea foods, saeu-jeot and myeolchi-jeot in salted fish, and pear and apple in fruits. The preference for kimchi sub-ingredients were high for sesame leaf and yeolmu in vegetables, saeu-sal and squid in sea foods, saeu-jeot and nakji-jeot in salted fish, and pear and apple in fruits. The foods using kimchi preferred and often offered with school meals were kimchi-jjigae, bokkeumkimchi, kimchi soup, kimchi-bokkeum-bap, and kimchi-jeon. The kimchi sub-ingredient for which students had the greatest preference was meats. Among the foods using kimchi with meats, the most preferred were kimchi-pyeonyuk bossam, doejigogi kimchi duruchigi, and kimchi galbi-jjim. Among the foods using kimchi with noodles, the most preferred were kimchi- bibimmyeon, kimchi -naengmyeon, and kimchi-cheese spaghetti. Among the foods using kimchi with vegetables, the most preferred were kimchi-pa-jeon, kimchi- deopbap and kimchi- goguma gui. Of the foods using kimchi with processed foods, the most preferred were kimchi-mandu, kimchi-bacon jumeok-bap and kimchi- cheese omelet. Among the foods using kimchi containing sea food, kimchi-haemul bokkeum-bap, kimchi-hoe-deopbap, and kimchi-saeu-jjim were most preferred. Overall, these results suggest that various kimchi sub-ingredients and foods using kimchi should be improved for kimchi intake of school meals.

        This study was carried out to investigate the effects of various kinds of commercial salts, including sun-dried (Korea), purified, and traditional salts on the chemical and sensory properties and growth of microorganisms involved in kimchi fermentation. Kimchi was prepared by salting in 10% NaCl solution for 2 hours followed by addition of other spices and fermentation at 20℃. The decreases in pH suggested that kimchi fermentation can be classified into 3 steps: initial, intermediate, and final stages. In texture analysis, the hardness and fracturability of traditional salt kimchi were higher than those of regular kimchi. From the sensory evaluation test for kimchi, sensory scores were high for traditional salt addition, especially taste, overall preference and texture. Among various microorganisms related to kimchi fermentation, the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Pichia membranaefaciens and Escherichia coli were examined. Based on the conditions of kimchi fermentation, a 2% and 5% concentration of each salt were studied. Also, the conditions of the cultures at 37℃ were examined. There was no considerable difference in the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Escherichia coli in the different kinds of salts. However, the growth of Pichia membranaefaciens was strongly inhibited by a 5% concentration of traditional salt during incubation at 37℃.

        본 연구는 김치건조분말을 제조하는 과정에서 김치의 발효과정과 건조 전후에서 나타나는 향기성분의 변화를 조사하고, β-cyclodextrin의 첨가로 인한 향기성분 포집효과를 검증하고자 GC-MS를 이용하여 분석실험을 실시하였다. 김치를 제조하여 20oC에서 발효시켰을 때, 초기 2일째는 dimethyl sulfide와 carbon disulfide가 생성되었고, 7일이 경과하였을 때, dimethyl disulfide, methyl 2-propenyl disulfide, allyl methyl sulfide, and di-2-propenyl disulfide의 황화합물이 주된 향기성분으로 검출되었다. 본 김치시료를 감압건조 하였을 때, 11개 화합물이 검출되지 않았고 dimethyl sulfide, acetaldehyde and methanethiol를 주로 포함하는 13개 화합물이 잔류하였다. 건조공정 중에서 김치 향기성분의 손실을 최소화하고자 0.25-1.0% 농도의 β-cyclodextrin을 건조보조제로 첨가하였을 때, 향기성분의 포집효과에 의해 건조 김치분말에 잔류하는 향기성분의 함량이 평균 3% 증가하였다. 본 연구결과로 볼 때 cyclodextrin은 건조 김치분말 제조공정뿐만 아니라 건조식품제조에서 건조보조제로 효과적으로 사용할 수 있을 것으로 보인다.
