The production of plum jangachi requires the cleaning of plums, immersion in saltwater, separation of seed and pulp, removal of impurities, and addition of sugar. In most farms, the separation of plum seed and pulp is carried out manually, requiring considerable labor, which is why plum jangachi is expensive. To solve this problem, this study designed and manufactured automatic, semi-automatic plum seed and pulp separators. During the design process, the characteristics were compared, and the machine power was determined through on-site test after manufacture. As a result, automatic machines used plums 180° arrayed and six reverse-edged blades, semi-automated plums 180° arrayed, and six blades, each with a 68% and 57% pulp recovery rate and a machine power of 80 kg/h and 62 kg/h respectively. Overall, the mechanization of plum processed food will reduce labor and increase the market value of plums compared to the previous method.

Jeupjang like salted soybean paste with vegetable is the Korean traditional side order eating at table. Bibliographical studies on the Jeupjang in historic books such as Jeungbo-Sanlim-Keongjae(Re-edition of agriculture economic), Imwon- Keongjae Ji(Book of country economic) and Keuhap-Chongseo(Handbook of household) described the Korean food in the 18 century carried out. In addition, investigation and analytical studies on various home-made Jeupjang in present was accomplished. Jeupjangs were classified into three types according to variety preparing methods. Three types were fermented soybean paste (Doenjang) type using traditional Meju(soybean cake stater) for Jeupjang, salted pickle (Jangachi) type buried cucumber and eggplant into soybean paste or soysauce (Kanjang), and salted sauer kraut (Kimchii) type prepared vegetable in Jeupjang-Meju mash. The procedures for producing Jeupjang were Jeupjang-Meju making, and mixing vegetable with Meju powder into brine. At last process was fermented in horse wastes or grasses for 7-14 days. But manufacturing methods of Jeupjang before the 18 century were different in present. Nowadays glutinous rice, red pepper powder and various vegetable were used for domestic Jeupjang.

This study was conducted to investigate the standardization of kimchi and related products. There are about 339 kinds of kimchi and related products in Korea. Half of those various kimchi was 50% of the total products, and the other groups are in the order of Jangachi (high salted vegetable pickles, Saengchae (a salad type kimchi), Kakduki(reddish kimchi), Keotjulyi(nonfemented kimchi), Pickles, Seobakji (kimchi based on raddish, fish and other ingredients) and Shickgae (lactic fermented fish products). About 200 ingredients (chinese cabbage, raddish, cucumber, other vegetables, fruits, seaweeds, fish, meat etc.) were used for those products. Tongbaechu kimchi (whole headded chinese cabbage kimchi) and Possam kimchi (wraped kimchi with chinese cabbage leaves) were made by about 30 ingredients, respectively. Kakduki, Oyster-kakduki, Chonkak kimchi (kimchi based on small raddish with leaves) and Tongchimi (raddish kimchi with brine soup) were made by raddish and more than 10 ingredients, but the subsidiary ingerdients were less than that of chinese cabbage kimchi. Other products such as Yulmu kimchi and Oisobaki (a cucmber kimchi) were also dicussed.

Objectives: This study was conducted to identify factors that influence the consumption of temple food and to find systematic methods improving the popularization of temple food. Methods: A self-administered questionnaire was applied to 304 temple food restaurant visitors, including 232 local and 72 foreign individuals. The questionnaire was designed to investigate recognition, consumption, preference and popularization of temple food among restaurant visitors. Results: The study population consisted of 30.6% men, 69.4% women. 76.3% were Korean while 23.7% were foreigners. The responses on their impression on temple food contained the words, "vegetarian" (4.64), "plain and familiar" (4.19), and "good for dieting" (4.16). The most commont reason to favor temple food was its "mild taste" (63.0%) in the local group while foreigners preferred it because it is "good for health" (35.8%). The preferred kind of side dish of the local group was roasted dish (4.40), stir-fried dish (4.39), blanched vegetables (4.36), and food boiled with sauce (4.23); foreigner's high preference was for stir-fried (4.67), Jangachi (4.63), food boiled with sauce (4.56), and Buggak (4.55).. Most respondents thought that it is necessary to maintain the traditional form of temple food. While 43.5 percent of Koreans responded that "the five pungent vegetables" could be allowed, 62.8 percent of foreign respondents said it is permissible. Conclusions: A systematic approach to improve the temple food that reflects both foreign and local preference while maintaining its originality is necessary for its globalization. Furthermore, restaurants specialized in temple food should be expanded and promoted through effective marketing strategies that would make the cuisine easily accessible and spread throughout the world.

Lactic acid bacteria was isolated for the production of probiotic animal feed supplemented with garlic and its antimicrobial properties were investigated. A total of 112 strains of lactic acid bacteria which grew on the medium containing garlic extract were isolated from kimchi, jeotgal, and jangachi. Among them 14 strains were tested for acidand bile salt-resistance as well as antimicrobial activities against animal pathogenic bacteria such as Salmonella choleraesuis, Escherichia coli, Staphylococcus aureus, and Shigella flexneri. Of these strains, a strain P'GW50-2 from pickled scallion with most desirable properties was selected and identified as Lactobacillus plantarum TJ-LP-002. Antimicrobial activity of L. plantarum TJ-LP-002 showed relatively wide range of inhibition spectrum against Gram negative bacteria such as Aeromicrobium hydrophila, E. coli, Pseudomonas, Salmonella, Shigella, and some Gram positive bacteria such as Bacillus cereus, Staphylococcus aureus, Clostridium perfringens, and Propionibacterium.

The principal objective of this study was to develop and standardize a preparation method for low-sodium tomato jangachi (traditional Korean pickle) via short-term fermentation with immature green cherry tomatoes. In order to determine the preferred concentrations of soy sauce and soaking temperatures of immature cherry tomato pickles in different stages of storage, we conducted an analysis of physico-chemical characteristics and microbiological properties, and also performed a preference test on samples of immature green cherry tomato pickles. Immature cherry tomatoes were prepared in three different soy sauce concentrations --20, 40, and 60%-- and three different soaking temperatures --60, 80, and 100$^{\circ}C$-- and then stored for 28 days at 5$^{\circ}C$. As a result, the pH increased significantly with increases in the amount of soy in the dipping solution (p<0.05). The saltiness was maintained at levels of approximately $0.17{\sim}0.28%$ (20% group), $0.32{\sim}0.67%$% (40%group), $0.48{\sim}1.00%$ (60% group) during storage periods. These results show that the saltiness of immature cherry tomato pickles was substantially lower than that of commercial pickles. The contents of reducing sugar and lightness decreased significantly with increasing concentrations of soy dipping solution. The redness and yellowness values of the tomatoes decreased significantly with increasing concentrations of soy sauce. Additionally, the lower the concentration of soy sauce used, the more rapidly the hardness of the immature cherry tomato pickles was reduced at 100$^{\circ}C$. PME activity moved within a narrow range, and then stabilized during the storage period. With regard to the results of the consumer preference test, 20%-100$^{\circ}C$ was the most preferred condition overall, 40%-80$^{\circ}C$ was the condition in which the texture was most preferred, and 40%-80$^{\circ}C$ was the condition that yielded the highest color scores.

This study was focused on identifying the difference of food preference according to body size of elementary school boys in Daejeon city. In order to measure the food preference, the degree of liking by means of a 5-point Hedonic scale was asked to 198 boys of 5th grade from six schools throughout Daejeon for 144 food items in 17 food groups composed of main dish, side dish and dessert : cooked rice, noodles or breads, as main dish, kimchi, tang.guk.zzigae, gui, zzim, bokeum, fried.pan-fried, jorim, muchim.namul or jangachi, as side dish, fruits, beverage, milk, rice cake or anacks, as dessert and for best preferred taste among five basic. The survey was conducted in rune, 1997 by questionnaires. Overall food preference of the subject was inclined to be higher in most of dessert food : fruits, beverage, milk or snacks, but to be lower in side dishes of Korean conventional food : jangachi, muchim, namul, jorim, kimchi and tang.guk .zzigae. The percentage of boys preferring cocked rice to noodle or bread as main dish was as much almost double in overweight boys as those of underweight or normal weight boys. None of the food group among 17 groups was significantly different in the food preference by body size of the subjects. However, food preference score of overweight group showed a trend to be higher in 11 food groups except less calorie-dense food groups such as fruits, noodles, rice cake, cooked rice, soup and stew and braised food (jorim) than normal or underweight group, and they seemed to prefer especially high-protein and high-fat foods. Being based on 3 points of preference score as the criterion for comparison, underweight group showed higher preference only in fruits group but showed lower preferences in 12 food groups among 17 groups than other groups.

The purpose of this study was to determine the sodium (Na) and potassium (K) content of school meals served in elementary and junior high school in Korea. In this study, 872 kinds of school meal dishes were collected from twelve elementary and twelve junior high schools located in four different cities in Korea (Daegu, Masan, Gwangju, and Jeju). The dishes were classified into three main categories; staple dish, subsidiary dish, and dessert. Each main category was further sub-classified into 4 kinds of staple dishes, 15 kinds of subsidiary dishes, and 5 kinds of dessert dishes. The Na and K content of dishes were then analyzed by atomic absorption spectroscopy. The Na content of individual dishes showed considerable differences, ranging from 9 to 2,717 mg/100 g. Among the staple dishes, cooked rice contained relatively less Na, but other staple dishes such as a la carte, noodle, and rice-gruel contained considerably high amounts of Na. Regarding the subsidiary dishes, the Na content of salad was low, but those of Jangachi, stir-fried dishes, and kimchi were considerably high. Among the dessert dishes, beverages, fruit, and milk/dairy products contained relatively low amount of Na, while rice cakes and baked goods, and snacks contained noticeably high amounts of Na. Unlike the Na content, the K content between the dishes did not show much variability. Cooked rice and rice cakes contained relatively low amounts of K, similar to other dishes, and ranged from 104 to 220 mg/100 g. The Na/K ratio was especially high in rice cakes and Jangachi, while of the ratio in beverages, milk/dairy products, salad, and fruit were pretty low. The total content of Na and K and the Na/K ratio of elementary school meals were 974 mg, 378 mg and 2.7, respectively, and those in junior high school meals was 1,466 mg, 528 mg and 3.0. The results show that most school meals provide a significant amount of Na but significantly small amounts of K, as suggested by the Dietary Reference Intakes for Koreans.
