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.

Effects of cultivars, cooking, and processing on hemagglutinin activity were evaluated by observing macroscopic hemagglutination using serial twofold dilution of trypsinized human blood type-O or rabbit blood. Hemagglutinin activity was expressed as maximal geometric dilution fold. Agglutination of rabbit blood was more sensitive compared to human blood. Hemagglutinin activities of glyphosate-tolerant soybean, HS2906, and imported conventional soybeans were not statistically different, although significant differences were observed among conventional soybean cultivars cultivated in Korea (286 to 1535 HU/mg protein). Time required to reach fifty percent inhibition of hemagglutinin activity ($IT_{50}$) value decreased with increasing cooking temperature and pressure. Most effective conventional cooking method to inhibit hemagglutinin activity was pressure-cooking ($IT_{50}$: 1.36 min). Calculated activation energy based on reaction rate constant was 4.88 kcal. No hemagglutinin activities were detected in processed soybean products such as tofu, soybean paste, and soysauce.

This study attempted to determine the effect of various thawing methods and storage periods on the quality of froen cooked rice. Frozen cooked rice was thawed at four different methods, such as pressure cooking, conventional cooking, microwave heating and thawing at room temperature after 10 days, 30days and 90 days frozen storage. We conducted a physico-chemical analysis (moisture content, dehydration rates, degree of gelatinization, color value and texture) and sensory evalution on the frozen-thawed cooked rice. The study showed that there were no significant differences on the quality characteristics of frozen-thawed cooked rice during the storage period of 90 days. However, the thawing method of pressure cooking caused high moisture content, rapid dehydration rates, and a high degree of gelatinization on the cooked rice. Thus, the desirabililty for the rice diminished becaused of the excess moisture content and the change of appearance and testure in the rice due to the high temperature. There were similiar quality characteristics to the cooked rice after forzen-thawing whether by conventional cooking or by microwave heating and just after cooking. Thawing at room temperature also caused a significant decrease in quality characteristics.

This research was conducted to develop a new approach to Chuncheon Dakgalbi processing by various chicken materials, seasoning (conventional sauce/CS and new approach of seasoning by adding the curing mixture/CSA), and cooking methods. Three chicken breeds (broiler, old broiler and spent laying hen) were divided into five experimental groups: broiler-CS, old broiler-CS, old broiler-CSA, spent laying hen-CS, and spent laying hen-CSA. All samples were stored at $5^{\circ}C$ for 12 d. For sensory evaluation, all samples were cooked with conventional cooking (pan grilling) or high temperature and pressure cooking (at $121^{\circ}C$ with pressure 1.5 $Kg_f/cm^2$ for 30 min). The chicken material analysis showed that the moisture and crude protein content, cooking loss and shear-force of the old broiler and spent laying hen were higher (p<0.05) than those of the current broiler, but the crude ash, crude lipid and WHC were lower (p<0.05). The addition of CSA increased the pH value and reduced the lipid oxidation at the end of storage regardless of chicken breeds (p<0.05). The high temperature and pressure cooking method seemed to increase the taste, smell and overall-acceptability scores of the old broiler and spent laying hen Chuncheon Dakgalbi regardless of the implementation of new approach of seasoning (CSA). In conclusion, an old broiler and spent laying hen can be used as material of Chuncheon Dakgalbi by the application of a new approach of seasoning and cooking method.
