In this study, portective effect on DNA damage several mushrooms (Pleurotus ostreatus, Flammulina velutipes, Lentinula edodes) according to cooking methods was investigated using Comet assay. Three edible mushrooms were cooked by grilling, blanching, pan-frying, or by preparing 'Jeon' (traditional Korean pancake). Cells were incubated in medium with 4 kinds of samples for 48 h ($37^{\circ}C$) were further treated with hydrogen peroxide ($H_2O_2$) for 5 min as an oxidative stimulus. Oxidative damage was evaluated by single-cell gel electrophoresis (Comet assay) and quantified by tail DNA% (TD), tail length (TL), tail moment (TM). Though oxidative DNA damages expressed as TD, TL, TM of 4 cooked samples were higher than raw sample, which means lower protective activities, all samples including raw sample had significantly higher protective effects than the positive control (p<0.05). The protective effect on DNA damage of cooked samples decreased much more when soybean oil added, likely due to the thermal oxidation of oil during cooking. Although heat treatment could degrade protective effect on DNA damage of mushrooms, the cooked mushroom had significant effect on oxidative stress. In conclusion, grilling and blanching were the most advantageous cooking methods to protect oxidative DNA damage induced by $H_2O_2$.

This study was carried on the oxidative stability and the real practice possibilities in cooking of fat replacer MCT. Nowadays, it was known that fats and oils had become causes for cardiac disease, obesity and cancer, so the new materials were needed for fat substitute that has less fat contents and low calories. The food industry concerned about fats and oils had been researched and developed new and various kinds of substitute fats. MCT(medium chain triglycerides) is one of the fat based fat substitutes used as fat replacers. The POV of com germ oil(CO), soybean oil(SO), shortening(ST), butter(BT), their blended oil with MCT 10-50%(w/w), and MCT were determined and oxidative stability by POV was compared MCT with those of them. MCT has shown higher oxidative stability than CO, SO, ST, BT, so oxidative stabilities in all kinds of blended oils become higher and higher by the increased substitution ratios. In case of bread, the volume of bread prepared with MCT(MCT bread) substituted for ST at 10-40% level(w/w) were increased a little comparing to that made of shortening(ST bread). But degree of gelatinization of MCT bread were a little lower than ST bread, at the substitute ratio above 40%, the degree of gelatinization were reduced greatly. These phenomena were sustained in 9 stored days. While baking losses of MCT breads were almost same as ST bread until 30% substitute ratio, and the appearances of MCT breads were similar to ST bread until 40% substitute ratio. Also rheological properties and color(Lab) of MCT breads had shown no different significantly from ST bread until 20% substitute ratio, but by the results of sensory evaluation, overall acceptance including appearance, color, flavor, taste, texture of MCT breads were recognized almost same as ST bread by panel until 40% substitute ratio. Depends on the above results, we can suggest that 30-40% of MCT will substitute for shortening in making bread in order to reduce fat and calories intake amounts.

The effect of emulsion treatment on the separation of quick-cooking rice kernel after drying and the quality of reconstituted quick-cooking rice made of a Japonica variety were investigated. Among the several stages of emulsion treatment tested, immersion of cooked rice before drying was the most effective on the separation index. Immersion condition of 3 min at $30^{\circ}C$ was found to be the most desirable. Emulsion composed of 5% soybean oil and 0.5% sucrose fatty acid ester (HLB : 9.5) was found to be the most effective to yield the separation index of 86%. By applying the above mentioned emulsion, the separation index was improved by 30 compared with untreated one. The quality of the quick-cooking rice manufactured by the emulsion treatment was found to be as good as untreated one.

A special form of questionaire was prepared and distributed to 502 housewives in seoul from Feb. 8th to 22nd in 1989. The results were as follows: In Cooking methods, they tended to follow in the steps of their mother, and it took about half an hour or an hour to prepare a meal. They cooked fried foods once or twice a month. Whenever they fried foods they need new oil. Followings were details of cooking method mainly used by housewives. Fishes were tended to be roast, vegetables to be dressing and seasoning. Highly milled boiled rice was best preferred as the cheif food, and it was cooked by following procedure; First rice was washed, and steeped in water for the time being. Next, the water was poured out and water was filled again, then rice with the water was boiled. Fish Chige was cooked in the way that fish was put into the boiled soup. Fermented sao-bean paste Chige was cooked using water in which rice had been washed. Hard-boiled beef with soy sauce was made using the method that soy sauce was properly poured after beef was boiled. A Spinach was boiled shightly with salty water. In view of those results, there were many cases that housewives did not only utilize their knowledge about foods in real dietary life, but also fell short of endeaver to do so. They chiefly made use of the cooking methods instructed from their mother or husband's mother. In conclusion, in order to illuminate housewives to have an exact nutritional knowledge about foods and cooking methods getting out of the loss of nutritions, nutritional education program must be provided for housewives.

This study was carried out to investigate the effect of the addition of olive and soybean oil on the color, water holding capacity, cooking loss, increase rate of thickness, decrease rate of diameter, pH, VBN content and TBARS value of ground pork loin during cold storage for 15 days. Ground pork loin were prepared by three types such as ground pork loin containing 20% pork fat (GP-P), ground pork loin containing 20% olive oil (GP-O) and ground pork loin containing 20% soybean oil (GP-S). The $L^{\ast}$ (lightness) and $b^{\ast}$ (yellowness) value of GP-P, GP-O and GP-S were not significantly different during storage, and the $L^{\ast}$, $a^{\ast}$ and $b^{\ast}$ value of GP-P were higher than those of GP-O and GP-S (p<0.05). The water holding capacity tended to increase along with storage period, the water holding capacity of GP-P was higher than that of GP-O and GP-S. Also, the cooking loss of GP-P was lower than that of GP-O and GP-S (p<0.05). The increase rate of thickeness by cooking increased along with storage period, but the decrease rate of diameter was tend to decreased with increase in storage period (p<0.05). The pH of all ground pork loins decreased until storage at 5 days, but increased at 15 days (p<0.05). The VBN content of all ground pork loins increased along with storage period, and the VBN content of GP-P was higher than that of GP-O and GP-S (p<0.05). The TBARS value of all ground pork loins increased along with storage period; also, the VBN content of GP-P was the highest among all ground pork loins and GP-O was the lowest among all ground pork loins (p<0.05).
