The purpose of this study was to investigate what kinds of foods university students consume, how often they go out eating, and the regularity and amount of their meals. A questionnaire survey was conducted on 600 university student (home with Parents $40.8\%$: house of relatives $5.5\%$: boarding with cooking $43.3\%$: dormitory $10.3\%$). The main results are as follows: PIBW(percent ideal body weight) was under weight($49.2\%$), normal weight($40.7\%$), over weight($6.0\%$) and obese($4.2\%$). Many students had breakfast irregularly(boarding with cooking: $81.2\%$> home with parents: $71.8\%$> dormitory: $54.8\%$> house of relatives: $54.5\%$). Students who had a meal of average size were $32.5\%$(for breakfast), $61.3\%$(for lunch), and $39.5\%$(for dinner). Students who were home with parents and boarding with cooking had more eating for breakfast and lunch than those who were house of relatives and dormitory. Students who were home with parents and dormitory students ate more often milk, milk products, and kimchi than house of relatives and boarding with cooking students. Home with parents, boarding with cooking and dormitory students ate more often meat, milk, bread, fast food, and instant noodles than house of relatives students. Home with parents, house of relatives, and dormitory students ate more often fish, dried anchovy, and vegetables than boarding with cooking students. Dormitory students ate more often snacks, such as alcohol and fruits, than home with parents, house of relatives, and boarding with cooking students.

An extrusion process was to make an onion kimchi snack from rice grit and onion kimchi powder, in an effort to enhance the nutritional value, flavor, and physicochemical properties of the extrudate. This study investigated optimum conditions (moisture content, barrel temperature, and the content of onion kimchi powder) for the production of high-quality rice extrudate products, and measured quality properties (water absorption index, texture, expansion ratio, and color) of rice extrudate to which onion kimchi powder had been added. Onion kimchi powder at 3%, 5%, 7%, and 10% (all w/w) was mixed with rice grit and the mixture then extruded in a twin-screw extruder. The texture of onion kimchi mack became softer as onion kimchi powder level rose, and water absorption ability increased. The expansion ratio and the lightness of extrudates decreased with increases in onion kimchi powder levels. The maximum water absorption index am the minimum hardness were obtained with 10% onion kimchi powder. Rice extrudate with 10% onion kimchi powder was suitable for extrusion cooking md obtained the highest score for overall acceptability by sensory evaluation.

The effects of the addition of Kimchi powder at levels of 1%, 2%, and 3% (w/w) to sausage formulation on the quality characteristics of low-fat sausage were determined. The CIE L-values of low-fat sausages were lower than the control (p<0.05), and were inversely proportional to the level of Kimchi powder (p<0.05). The CIE a- and CIE b-values of sausages increased with increasing levels of Kimchi powder (p<0.05), and the pH of sausages decreased in proportion to Kimchi powder acidity. Kimchi powder was effective at retaining added water in low-fat sausages since cooking yield, emulsion stability, and viscosity with the addition of 3% Kimchi powder was similar to that of the control. The protein and ash contents of sausages were not affected by Kimchi powder addition (p>0.05), while sausages containing 3% Kimchi powder had the highest water content (p<0.05). With increasing Kimchi powder concentration, hardness, gumminess, chewiness, and sensory scores increased in low-fat sausages (p<0.05).

In the life style of the neolithic age, cooking and sleeping space was in one room dugout without differentiation of spaces, so to say one room system. Ro(a kind of primitive fire place) was used for both cooking and heating. However, in the early part of the Iron Age, the uses of Ro were separated into two major uses of cooking and heating. Especially, L-shaped Kudle(an unique under floor heating structure of Korea) was invented for the new system of heating, extending to Koguryo Period. The life style of Koguryo Dynasty could be seen through the mural paintings of tombs. For these mural paintings contain of cooking space(Kitchen), meat storage, and mill house drawing, we can recognize that houses were specialized many quaters according to their function. Also a kitchen fuel hole for preparing food was built without relation to L-shaped Kudle. But during Koryo Period, Kudle could be set up all over the room, the so-called Ondol(the unique Korean panel heating system) settled down. From this development of heating system, room could be adjacent to kitchen, and kitchen fuel hole and heating fuel hole be onething. This system was developed with variety, extending to Chosun Dynasty. In the period of Chosun Dynasty, a kitchen was made close to an Anbang(Woman's living room), and Anbangs Ondol was heated by the warmth of a cooking fireplace. Therefore Handae Puok, outer kitchen was used in summer. As for its storage space, it was seen that there were a pantry near the kitchen and a store house constructed as an independant building. In the latter, it was devided into a firewood storage, a Kimchi storage, and a rice storage, etc. Especially it is a unique feature that 'Handae-Duyju', an outer rice chest which keeps rice, was constructed as an isolated small building.

This study was conducted to find out the desirable measures for maintenance and development traditional foods when abroad, by investigating the knowledge and actual state of utilization of Americans residing in the Los Angeles on Korean traditional foods. The 308 respondents of questionnaires were taken. 96% of the respondents demonstrated interest in traditional foods. Among kinds of traditional food, the most preferable food was boiled rice(71.4%) and Kimchi(70.9%) , The that traditional foods are used were good taste(45.4%) and familiar taste(41.6%). The reason for avoiding them was, mainly, troublesome cooking methods (46.3% ). Conclusively, the Korean Americans residing in the Los Angeles have made good use of boiled rice and Kimchi a staple common food, but special foods. ceremonial foods and festival foods were hardly used. To maintain Korean traditional foods when abroad, it is necessary that older generations sometimes offer opportunity to meet with them to the coming Korean generations, and Korean food companies develop and export standardized and simplified traditional foods.

Preferences of 814 elderly living in Incheon for dishes, food materials and cooking methods were investigated. The survey was conducted from Dec. 2000 to Jan. 2001 by questionnaires. Subjects preferred cooked rice with beans, kalkooksoo(hot noodle), gomtang(soup with beef), bibimbap(rice with assorted mixture) to other staple dishes. However, preference for hashed rice or curried rice was very low. More than 50% of the subjects liked soybean paste soup and stew, and the ratio of elderly who liked Chinese cabbage kimchi was 68.7%. There was no significant difference in preference for pan-fried foods according to food materials in them. Subjects liked injolmi(waxy rice cake), shikhye(fermented rice drink) and coffee the most. Most subjects preferred plant foods like vegetables, legumes and seaweeds to animal foods. Preference of elderly for milk and yoghurt was reatively high; however, that for ham, butter and cheese was low. Elderly in Incheon liked roasted beef, beef soup and roasted pork the most. Chicken was preferred when it was boiled in water with garlic, ginseng, and so on. Cooked and seasoned vegetables (Namul) were the most preferred type by elderly. Preferences for dishes and food materials were more affected by living places of the subjects than by sex, and the reverse was true in preference for cooking method of food materials.

Recently, interests of dietary fiber associated with critical physiological effects have been rising in Korea physiological effect in the body. In the present study, the contents of fiber components in 15 kinds of vegetables being consumed commonly in Korea were investigated, and the effects of various treatments (cooking and Kimchi fermentation) on fiber were studied. The results are summarized as follows. Fiber contents of vegetables were 11.8∼31.9% of neutral detergent fiber(NDF), total insoluble dietary fiber, 10.9∼25.4% of acid detergent fiber(ADF), 8.8∼23.8% of cellulose, 0.6∼10.6% of hemicellulose and 1.0∼5.2% of lignin, on dry weight basis. Especially, peppers had higher contents of NDF than the other vegetables. In the vegetables used in the present study, it was found that a great portion of NDF, total insoluble dietary fiber, was composed of cellulose because cellulose covered 63% of NDF. 'Cooking increased the NDF, ADF and cellulose contents, and most change was due to the change of cellulose. The values of hemicellulose and lignin showed an Irregular pattern upon cooking. Fermentation slightly increased NDF, ADF and cellulose, while hemicellulose and lignin showed irregular pattern.
