  • 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.

  • Milk and milk products, especially the cow's milk and cheese, have been used since the ancient time. Because they contains almost all kinds of nutrients that are necessary for human beings except for iron, n-3 fatty acid, and vitamin C. Milk is an excellent dietary source of protein, calcium and phosphorus. The biological value of milk protein is as high as those of red meat and eggs. So cheese, a food processed from concentrated milk protein, is highly recommended food for the patient of diabetes mellitus. Because the major form of milk lipids is n-6 fatty acid, milk and milk products may not be a good food for the patients of cardiovascular disease. But the nutritional quality of milk lipids cannot be inferior to those of margarine, fish oil, and vegetable oil. Milk has been produced commercially since 1936 in Korea. The most popular milk product is a drink milk now in Korea. But according to the change of dietary pattern the consumption of yoghurt and cheese has been enormously increased during the last 20 years. As the soy sauce, tofu, and soy been paste have been the fundamental seasoning and source of protein in Korea, milk and cheese have consisted the essential flavor of western cuisine. But the basic idea for the usage of protein, peptides, and amino acids are the same. We found that milk and milk products can be nicely added in many Korean dishes such as Juk, Mandoo, Jeon, and Bindeatuk for the diversity of traditional flavor.

  • The quality of commercial sauce products was evaluated through pH, soluble solid content, salinity, water activity and microbial analyses. The pH of sauces was 2.38~5.30, soluble solids were between 6.03 and 71.67, and distributions of salt were 0.23~5.00% in 32 commercial sauce products. In addition, water activity of vinegar red pepper sauce and spicy soft tofu stew stock were determined 0.773 and 0.988, respectively. Yeast, mold, Staphylococcus aureus, E. coli and coliform were not detected in any sauces. Higher level of total viable cells (TVC) resulted in pH over 4.2. TVC of shelf-stable sauces was 1.0~3.6 log CFU/g. TVC of seven sauce products was classified as non-potentially hazardous foods by temperature controlled for safety standard (TCS), even though levels were over acceptable guidelines of the USDA (3 log CFU/g). These results indicate that the standard and classification of commercial sauce products should be modified and controlled strictly.

  • Objectives: This study developed two weeks menu using temple foods, assessed preference for the menu among ordinary people, and determined the possibility of using temple foods to make out institutional food service menu. Methods: To make out the menu, 153 typical types of temple food were selected, under several conditions, thus including balanced food groups, natural foods in season, preparation time, preparation methods, and foods appropriated for institutional foodservice. Results: Developed menu contained 1905.8 kcal, had low fat content, high dietary fiber, vitamin, and mineral content, and good protein content in the nutritional respect, and fit protein requirements with low calorie content and high nutritional value. In the assessment of the food preference for 73 temple food items, most of the foods scored high (4 out of 5 points) for preference in general; therefore, the menu tended to be satisfied to the adults' preference. In particular, boiled rice (rice with chwi, rice with cirsium, rice with mushroom, rice with mushroom & vegetable and gimbap with tofu) and fried foods (fried shiitake with sweet & sour sauce and fried kelp) were highly preferred. Conclusions: The menu using temple foods can be a healthy choice for adults if it is well planned and managed. This study may be expected to provide basic data that would help developing menu to popularize temple foods. The above results could be applied at home as well as at foodservice institutes and furthermore could offer information for developing temple food products.

  • This study was carried out to investigate the differences of the dietary behavior of the college students by the type of the residence, that is, home-living, dormitory-living, and self-cooking. The responses of 307 students to the questionaire were analyzed. The average meal frequency of the students was 2.4 times a day. Breakfast was skipped most frequently, especially in dormitory-living and self-cooking students compared to home-living ones. Forty-three percent of the students were found to eat breakfast less than twice a week. Such a poor eating habit was mainly due to insufficient time or idleness. When the quality of the meal was evaluated, dormitory-living and self-cooking students had worse scores than home-living ones. The formers had poor dietary habit in terms of balanced breakfast and food diversity of each meal compared to the latter. Fast foods and coffee were consumed more frequently by dormitory-living and self-cooking students than home-living ones. The main food they eat was rice. However, female dormitory-living students had a higher tendency to enjoy bread for breakfast and noodle for dinner compared to the other groups. Home-living and self-cooking students had snack more frequently than dormitory-living ones, and female than male. In terms of snack time, most of the respondents had snack between lunch and dinner or after dinner. The percentage of those who had snack after dinner was greater in dormitory-living and self-cooking students than home-living students. Results of the food preference test showed that their favorite dishes were fruit salad, Bulgogi, uncurdled Tofu stew, Kimbab, and boiled rice. We observed that dormitory-living and self-cooking students had more problems in their dietary behavior. Therefore, they need to learn how to manage their own meals. This study might be helpful to develop nutrition education materials for the dietary improvement of the college students.
