This study was conducted to investigate the condition of frying oil used for frying chicken nuggets in a deep fryer. The acidification of the frying oils used, soybean oil (SB), canola oil (CA), palm oil (PA), and lard (LA), were determined as peroxide value, acid value, and fatty acid composition, after chicken nuggets were fried in them for 101 times. The acid value and peroxide value obtained were 5.14 mg KOH/g and 66.03 meq/kg in SB, 4.47 mg KOH/g and 71.04 meq/kg in CA, 2.66 mg KOH/g and 15.48 meq/kg in PA, and 5.37 mg KOH/g and 62.92 meq/kg in LA, respectively. The ranges of the major fatty acid contents were palmitic acid, 8.91-45.84%; oleic acid, 34.74-58.68%; linoleic acid, 10.32-18.65%; and stearic acid, 2.28-10.86%.Used frying oils for food except animal products have a legal limit for the freshness standard, set by the Food Codex regulations (AV<2.5, POV<50). Therefore, this study could help develop a freshness standard for frying oils used for animal products such as chicken nuggets. Based on the quality limits associated with food regulations stated, we suggested that the estimated frying times before acceptable freshness was exceeded were 41 for SB, 38 for LA, 53 for CA, and 109 for PA. This data may be useful in determining food quality regulations for frying oil used for animal products.

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 purpose of this study was to find the level of satisfaction and preferences regarding the mess provisions in the three military bases in Daegu, Korea. A total of 325 military personnel was surveyed for this study. The content of examinations consisted of the general characteristics, satisfaction, awareness, and preference for the mess. Furthermore, I investigated the general menu on a daily basis with the most or the least-preferred food. As a result, I found that fried dishes are most preferred by military personnel, and they second and third in their preferences are boiled, and mixed with dressing. I also found that military personnel like meat, sweets like ice-cream, fried pork chops or chicken, and fatty and processed food like hamburgers. On the other hand, they do not like dishes made with bean sprouts, squid, fish or kimchi. On the basis of the results, a balanced diet is needed for military personnel through the research and development of recipes using some of the least favorite ingredients such as fish, squid, and vegetables.

The purpose of this study was to provide a basic resource for establishment of hygienic management standards for meal delivery from the central kitchen to schools. Flow diagrams for delivery of food were analyzed, and time-temperature conditions of the food and environment were measured. Four different foods samples including Mexican salad, radish salad, stir-fried pork and vegetables, and stir-fried chicken and vegetables were collected after production and before service. Microbiological analysis was performed for aerobic plate counts (APC), Enterobacteriaceae, coliforms, E. coli, Salmonella spp., S. aureus, B. cereus, C. perfringens, and L. monocytogenes. After completion of production of cooked foods 2~3 hours were taken for the cooked foods to reach the temperature danger zone. Food temperatures at the meal service did not meet the recommended temperatures ($10/57^{\circ}C$) for conventional school food service systems. The highest APC counts were observed in radish salad (5.70 log CFU/g), followed by Mexican salad (5.18 log CFU/g). Enterobacteriaceae and coliform counts were within acceptable levels of those recommended by the UK Public Health Laboratory Service. No E. coli or pathogens were found. These results provide useful information for determination of microbiological hazards in school food service systems, and suggest that time-temperature control during delivery is necessary for the safety of cooked foods.

The purpose of this study was to evaluate the preference trend of children in the child-care centers in relation to certain environmental factors such as size of the residing town. This evaluation was conducted using questionnaire survey where the mother of each child was required to complete a preference questionnaire including 83 food items. Statistical data analysis was completed using SAS package program. The results of this survey showed the followings : 1. Generally, the preference level of the children living in large cities were higher than of medium cities except in case of vegetables, while the preference level of the children living in large cities were higher than those of rural area except in case of hard-boiling(jorim) and vegetables. The subjects showed high preferences to bulgogi(4.53), pork-cutlet(4.52), fried chicken(4.51), jajangmyone(4.45), kimgui(4.43), roasted fish(4.31), roasted ham(4.13). 2. There was a tendency that a la carte, bread and noodles received higher preference scores. Items of Korean style soup attained higher preference scores than stew(ggigae). The preference scores of fired, broiled or pan-fried items(jun) were higher than those of other items such as seasoned vegetables(namool). 3. The preference scores of children (routinely or occasionally) skipping breakfast or supper were generally low. There was no significant difference according to the existence of mother's job except in case of steamed or pan-fried items, provided that the preference scores of the size of the monthly income of the household except stew, provide that the preference scores of the children whose household had lower income were slightly higher in general.

Frying is the most popular cooking style used in food service institutions in Korea because fried dishes are well accepted by students. However, trans fat contents reduction have recently been required in many foods for health reasons Therefore, alternatives to frying such as oven baking or roasting are being used in many institutions. Steam convection ovens provide dry heat as well as steam so that they can be used to make a wide variety of Korean dishes. In this study, a menu acceptance test was conducted over 2 weeks. Pork, chicken, fish and potato dishes cooked by conventional cooking methods were served for 4 successive days, after which the same dishes were prepared using the oven. Overall, 322 junior high school students evaluated the traditionally cooked foods, while 316 evaluated the oven cooked foods. Comparison of the foods prepared using both methods only revealed a significant difference in the acceptability of foods on the fish menu (p<0.05). Specifically, the acceptance of fried fish was higher than that of the oven baked fish. Additionally, overall acceptance of the menu by males was higher than the acceptance by girls. Furthermore, students who had the preference for special ingredients showed a higher menu acceptance for the menu cooked with those ingredients. On average, approximately 25% of the meal was not consumed and left as plate waste. The portion of the fried fish not consumed was smaller than that of the oven cooked fish, but the portion not consumed did not vary based on cooking method for any other foods evaluated. Overall, it is expected that the oven cooking method will be a good substitute for frying or other cooking method for traditional Korean dishes.

2012년 3월부터 2012년 10월까지 광주시내 초 중 고등학교 주변 어린이 식품안전보호구역내 분식점, 길거리음식점 등에서 판매되고 있는 김밥, 떡볶이, 꼬치류, 오뎅, 튀김류 등 식사대용 및 간식용 어린이 기호식품 중 조리식품 124건에 대해서 탄수화물, 지방, 단백질 등 영양성분과 나트륨, 당함량 등을 검사하여 고열량 저영양 식품 해당여부에 대해서 조사하였다. 식사대용 어린이 기호식품 35건 중 토스트 12건이 모두 포화지방과 나트륨의 기준을 초과하여 고열량 저영양 식품에 해당되었고, 간식용 어린이 기호식품 89건 중에서 튀김류 4건과 닭강정 5건이 열량기준을 초과하였고, 또한 슬러쉬 27건 중에서 20건이 당함량을 초과한 것으로 나타나 총 29건이 고열량 저영양식품에 해당되었다. 그러나 이번에 조사한 식품들은 슬러쉬를 제외하고는 모두 저영양 식품 판단의 한 요소인 단백질 함량이 높고, 튀김류 등은 식품의 특성상 지방함량이 많아서 열량이 높고, 모두 조리식품들이기 때문에 식사로 섭취하게 되는 식품과 마찬가지로 나트륨 함량이 높아서 고열량 저영양 식품으로 분류된 것으로 보인다. 따라서 고열량 저영양 식품이라 하더라도 한두 번 섭취한다고 해서 문제가 생기는 것은 아니기 때문에 편식을 피하고 싱거운 맛에 익숙해지도록 하는 노력과 더불어 전체적으로 여러 유형의 식품들을 골고루 섭취하는 등, 올바른 식생활 습관이 어릴 때부터 형성되도록 소비자의 지속적인 노력이 필요할 것으로 생각된다.
