The present study investigated Bul-Chun-Wi Sacrificial Ritual (sacrificial service which has been handed down from generation to generation to worship the family ancestors in the period of $1400{\sim}1800$) and foods for the sacrificial service among fourteen head families in Andong area. The findings are as follows; 1. In Bul-Chun-Wi Sacrificial Rituals, family shrine has been maintained in good shape, and the table, dishes, and foods used in the rituals have not been changed so much until these days. 2. While vegetable soup is widely used as soup, one family uses the seaweed soup, the other soup mixed with meat, fish, and vegetable. Specially soybean-powdered soup, which is the distinguishable food in Andong area, has been used. 3. As a basic Ddock, mainly Si-Ru-Ddock(a steamed rice cake), piled up to 13-15 stacks, is used. Additional 7-9 kinds of Ddock are placed on top of the basic Ddock. 4. For grilled-meat food(Geuck), eight families use the raw meat, and one family uses the half-cooked meat. Recently, five families have used the cooked meat. Mostly used ones are meat-Geuck, fish-Geuck, chicken-Geuck, and the Geuck are not served one by one. Instead the Geuck are stacked in one dish designed for Geuck in order of meats from poultry, animal, fish, and shell. As the sub-dishes for rice, raw and cooked Geuck are used. 5. The number of stew (Tang) are 3 to 6 and 5 stews is the most popular. Commonly used stews are meat stew, fish stew, chicken stew, vegetable stew, blood stew, and organs stew. For the vegetable stew, buckwheat gel can be used. 6. As the fruit, chinese date, pear, nut and dried persimmons are the basic ones. The even number of 6 or 8 colorful fruits are used, while the odd number of 7 or 9 colorful fruits are used in three head families. 7. As Sik-Hae which is a drink and made from fermented rice, rice Sik-Hae or fish Sik-Hae has been necessarily used. 8. As raw meat dish, the liver of cow or meat is used. As a wrapping materials, the reticulum of a ruminant, green seaweed or thinly fried egg can be used.

Lipid-based functional components present in foods undergo chemical changes during cooking. Useful n-3 and n-6 fatty acids, phytosterols, tocopherols, and carotenoids are degraded by thermal cooking such as frying, resulting in loss of their physiological functions. However, conjugated linoleic acid and diacylglycerols can be formed during heating, which would be beneficial to the health. Degree of degradation and formation of the functional components depends on the cooking method, cooking temperature and time, lipid matrix containing the components, and the presence of other materials. Although it is clear that the content of each functional component varies during long-heating in a model system consisting of small numbers of components, the real foods cooked in a small scale for a limited cooking time do not show highly significant differences in the functional components contents from raw food materials.

In continuation of the previous $studies^{2{\sim}3)}$, the folate activity levels in 226 Korean food items were determined by a modified microbiological assay with Lactobacillus casei. There was a large variation in folate activity between the different food groups as well as between each individual food. There was also a wide variation in the biologic availability of folate in foods and the different forms of the folate with different foods in varying amounts. Data showed that almost always, foods cooked and/or processed were lower in folate activity than fresh or raw food and the amount of the loss varied greatly in each food. In calculating dietary intake, total rather than free folate activity levels should he used. In addition, loss of folate activity during cooking and processing of foods should be considered as a major concern for appraising diets and food supplies. Among all assayed food items, including Part $I^{2)}}$ and $I^{3)}$, yeast 2800. ug total per 100g the highest folate level. Soybean, spinach, Shepherd's purse and liter of beef and pork had over 100 ug total per 100 g folate activity. Folate ranging over 50 ug total per 100 g was found in all dried legumes, nuts and seeds assayed, Garland Chrysanthemum, leek, mugwort, wafer cress, asparagus, e99 folk and beef kidney. Wheat, sweet Potatoes,dried fungus, green onion, hotrod pepper, lettuce, radish and some fermented soybeen products had considerably higher folate content ranging around 40 ug total per 100 g. Substantial amounts of folate were not found in many food groups, and among specific groups, in part in starch, sweets, fruits, meat, fish, milk, and cooked and processed foods. Soused fish, oils and fats, beverages, liquor and seasonings, other than fermented soybean products, had almost no folate.

This study aimed at examine dietary attitude, eating behavior and food preferences of children in child care center. The children involved in this study were 153 boys and 134 girls, aged 3 to 6 years old. The eating frequency of breakfast and the number of meal times a day were significant difference according to sex(P<0.01). Reason for skipping breakfast was ‘no appetite’(49.3%). It was found that 51.5% of the children belonged to ‘fair’ in food habit score, while children in ‘poor’ and in ‘excellent’ were 25.0% and 9.7% respectively. There was no significant difference in food habit score between boys and girls. Their preferred staple foods were ‘cooked rice’ and ‘Chajangmyon’, their preferred soup was ‘seaweed soup’. Also, their most preferred side dishes with animal foods were ‘fried chicken’ and ‘Bulgogi’. The preference of ‘hard boiled soybean curd’ and ‘pan fried soybean curd’ among the side dishes with vegetable foods were significant according to the obesity index(P<0.05). Children preferred side dishes with animal foods to those with vegetable foods. First considered item in meal preparation was child's favorite(58.1%). Mother's response to child's unbalanced diet was ‘trying to persuade the child’(56.6%). It was significant according to mother's occupation(P<0.01). The nutritional management program at child care center is required to enhance the nutritional status of children. Also the nutritional education for the children and their meal planners is required for better growth and health promotion of preschool children.

The amount of sodium in the processed foods was evaluated by the information on the nutrition label. One-meal type foods as Ramen, Woodong, Naengmyon provide the most sodium reaching 30 - 70% DV per serving size. In Ramen not much difference was observed for the sodium content by food companies though each company provides various amount of sodium reducing as much as 25% DV. The proportion of female college students who read the nutrition information reached 62% but it remained 32% on the sodium information. They purchase low sodium foods rarely however their intention to buy low sodium foods increased up to 40% in condition that sodium information is given on the food label. Nevertheless 50% of them would not buy low sodium food if the taste is undesirable. Low sodium ramen cooked with 80% soup-base was acceptable by the subjects. Majority of them responded the soup was rather salty indicating the reduction of sodium in ramyeon is possible.

This study was conduced to identify the preference and intake frequencies of traditional Korean foods by Chinese-Koreans in the Yanbian region of China based on the hometown of the female head of household. Data were collected from 261 Korean housewives living in Yanbian. Twenty-six kinds of daily food items were surveyed. Analysis of variance was used to compare the similarities and differences among the three groups, which were divided according to hometowns in North Korea, South Korea, and China. The results for the traditional Korean daily food preferences showed that housewives born in South Korea are more likely to prefer cereal soup, vegetables soup, and fermented rice punch than housewives from North Korea and China. Considering the intake frequencies of traditional Korean foods, Korean housewives born in China are more likely to eat boiled rice and a bun stuffed with seasoned meat and vegetables, as well as beef and vegetables cooked in a casserole than housewives with hometowns in South Korea and North Korean. In this article, similarities and differences in the preferences and intake frequencies of traditional Korean foods are discussed, and implications for nutritionists as well as food marketers are provided.

B. cereus-produced cereulide as an emetic toxin is commonly isolated in starch-based cooked foods. This study examined the prevalence of B. cereus from ready-to-eat foods in markets by polymerase chain reaction analysis and determined the relationship between the level of B. cereus and the quantity of cereulide in the sample after different storage times and temperatures. The prevalence of general B. cereus in 43 starch foods was 32.6%, and the level of B. cereus ranged from 0.5 to 1.95 log cfu/g, meeting the Korea Food Code Specifications of 3 log CFU/g of B. cereus. No samples revealed emetic B. cereus. Fried rice samples were inoculated with a cereulide-producing reference strain, B. cereus NCCP 14796, to determine the level of B. cereus and the quantity of cereulide in the samples after storage for 0, 4, 6, 8, 20, 24, 30, 48, 72, and 96 h at 7, 25, 35, and 57℃. The average levels of B. cereus at 7, 25, 35, and 57℃ were 4.38, 7.31, 7.88, and 3.82 log cfu/g, and the levels of cereulide were 150.41, 1680.70, 2652.65, and 77.83 ㎍/mL, respectively, showing a significant difference according to the incubation time (P<0.05) and temperature (P<0.001).

Sodium is a major component that maintains homeostasis and physiological state in body. It is an essential mineral that the body cannot produce for itself, so it must be supplied from food. On the other hand, overindulgence is one cause of hypertension, stroke, stomach cancer, osteoporosis and kidney disease. The purpose of this study was to monitor sodium content in meals of school foodservice. In this study, 801 samples (main/side dishes) were collected from 8 school foodservice in Busan and Gyeongsangbuk-do, Korea. Samples were classified into 21 food items, which were cooked rices, cooked rice with seasoning, noodles, cooked gruels, soups, stews, tang and chon-gol, stir-fried foods, fried foods, pan-fried foods, hard-boiled foods, roasted foods, steamed foods, seasoned vegetables, preserved foods, kimchis, sauces, fruits, breads and snacks, beverages, and dairy products. The samples were analyzed by AAS (atomic absorption spectrometry) after microwave digestion. The sodium content of sauces (1459 mg/100 g) and preserved foods (1165 mg/100 g) was higher than those of other dishes. Aside from them, sodium contents of roasted foods (894 mg/100 g), hard-boiled foods (786 mg/100 g) and kimchis (737 mg/100 g) were relatively higher than the others. Sodium intakes from meals of school foodservice were calculated by multiplying food intakes by sodium contents. The average sodium intakes from one serving of school foodservice were 605 mg for younger boys, 572 mg for younger girls, 774 mg for older boys, 730 mg for older girls in elementary school. Boys in middle school took in 1423 mg Na whereas girls consumed 1063 mg Na in middle school. Results from this study can be useful for establishing database of sodium contents and intake in meals of school foodservice. The database will be helpful for providing information on managing food for children.

The purpose of this study was to develop a fusion-food cooking program and apply that to sixth grade elementary school students, and to investigate its' effects on their knowledge, preferences, and perceptions of Korean traditional foods. The program focused on ten components. Students learned the general features of Korean traditional foods and Western foods in the 1st lesson. They learnt about kinds, nutrition value, and histories of kimchi, Tteok (rice cake), and Jeon (pan fried food), and cooked two fusion-foods of kimchi, Tteok, and Jeon each. As a result of learning about those food items, the students advanced their knowledge (p < 0.001) of kimchi, Tteok, and Jeon. Their preferences for Tteok (p < 0.05) and Jeon (p < 0.01) were increased, but those for kimchi remained unchanged. The interest (p < 0.05) and preferences (p < 0.01) for the general Korean traditional foods were increased. In conclusion, our results suggested that the fusion-food cooking program had the ability to improve elementary school students' perceptions of Korean traditional foods by increasing their knowledge, preferences, and interest in them. Furthermore it was considered that the program could help students understand the value of Korean traditional foods and in turn may encourage them to consume such food items more frequently. Since the fusion-food cooking activity program can be a good learning program as shown by the results of this study, more fusion-foods cooking activity programs, which are not discussed in this study, should be evaluated and developed in the future.
