The study was conducted to establish the HACCP model for chicken dishes (deep-fried sirloin chicken, chicken and potato in red pepper paste, smothered chicken) sewed in 3 different elementary school lunch program during 2002. the hygienic conditions of the food facilities and environment were at the lowest limit of normal grade. Workers' practices should be improved: sanitary handling and proper holding of foods and utensils. Kitchen layout should be remodeled for separation of soiled and clean work areas. pH values of all items were over 6.0 which required careful attention. (omitted)

This study aimed to obtain basic data toward fostering understanding and interest in local foods, to the overall end of enhancing development and popularization of such foods. It also gives direction toward promotion of local food by researching attitudes toward local foods and viewpoints on requirements for improvement of such, among university students living in the Daegu-Kyungbuk area. The results of analyzing perceptional scores for native local foods in Kyungbuk by characteristics t showed statistically significant differences according to sex and duration of residence in Kyungbuk. Obstacles to the promotion of local foods include lack of marketing, lack of specialized restaurants, lack of knowledge, lack of menus, lack of generalization, and high price. The results of analyzing viewpoints on requirements for improved perception of local foods, there were statistically significant differences in active advertisement and marketing, diversity of local foods, and duration of dwelling.

The purpose of this study is to investigate children's satisfaction with baps, soups, pot stews, one course dishes, and kimchies provided by elementary school lunch program in Seoul area. Two hundred and thirty two children enrolled in 3 different elementary schools participated In this study through a questionnaire developed by the researchers. Conclusions drawn from the results of this study are 1) children seemed to be generally satisfied with foods provided by school lunch program : 2) it is necessary for children to control amount of food and salt and/or hot peppers depending upon their own preference; and 3) appropriate temperature of each food should be maintained by using thermos pots, and the shape of dining board needs to be improved for younger children's convenience.

Cooked rice is a staple food for Koreans which provides more than 60% of daily required energy. In 1960's, Koreans ate 600 g-800 g of cooked rice per meal and the energy obtained from cooked rice was almost more than 80% of the daily intake of energy. However, as the economy of Korea improved, the major industry has been shifted from agriculture to various manufacturing industries and the export of those products has been increased thus increasing the national income but decreasing the farming population and thus rice consumption have been decreased. It has been said that the decreased rice consumption is caused solely by decreased farming population but it can also be said that the decreased farming population is caused by decreased rice consumption. As the national income increases, the type of foods people consume have become diversified. Various processed foods such as convenience food or ready-to-eat food have been widespread, which are mostly made of wheat flour rather than rice.

The whole saltwort plant (Salicornia herbacea) was micronized to develop the table salt substitute. The micronized powder was mixed with distilled water and made into a spherical granule by using the fluid-bed coater (SGMPDW). The SGMPDW had superior flowability to powder; however, it had low dispersibility. To increase the dispersibility of SGMPDW, the micronized powder was mixed with the solution, which contained various soluble solid contents of saltwort aqueous extract (SAE), and made into a spherical granule (SGMPSAE). The SGMPSAE prepared with the higher percentages of solid content of SAE showed improved dispersibility in water and an increase in salty taste. The SGMPSAE prepared with 10% SAE was shown to possess the best physicochemical properties and its relative saltiness compared to NaCl (0.39). In conclusion, SGMPSAEs can be used as a table salt substitute and a functional food material with enhanced absorptivity and convenience.

Casein was chemically modified with acetic, succinic, and maleic anhydride and changes in functional pro-perties were evaluated as affected by the degree of modification. Chemical modification resulted in casein with unique functional properties depending upon the type of anhydrid used and the degree of modification. It was possible to control heat coagulation, calcium precipitability, forming and emulsion capacity and stability. At pH 4.5 heat coagulation was 0% in the case 74.1% acetylated casein; on the contrary, succinylation and maleyation resulted in highly heat sensitive protein. Foaming properties were improved markedly by suc-cinylation and maleylation at pH 4.5. However, emulsifying properties were enhanced only by maleylation.

The purposes of this study were to examine the needs in foodservice in the view of students and to determine the ways to improve the foodservice quality. A survey was undertaken from 381 high school students by using a self-completed questionnaire regarding the student' satisfaction on the foodservice. The collected data were analyzed by using SPSS program for descriptive analysis, t-test, and analysis of variance. The students assessed the importance and performance of the meal service as 4.19 and 2.52 out of 5, respectively, which suggests that the school foodservice needs to be improved. The attributes identified in Quadrant A, which was labelled 'focus here' and supposed to incidate the areas of high importance but in low performance, were the availability of meals that the students like, variety of menu, taste of the food, sanitary quality of the food, sanitized utensil, and response to complanints. The results of Importance-Performance Analusis(lPA) indicated the areas that the attention of management should be given to improve the quality of foodservice.

This study was attempted to standard Yukwa recipies by proposing optimal conditions for soaking time and the number of beating. Soaking time and the number of beating had effects on the number of peak, implying that 15 days of soaking time at $15^{\circ}C$ and 160 times of beating would be required. In Yukwa's microstructural image, the better groups were over 15 days of soaking time and as number of beating increased, the appearance improved. The longer soaking time, the better tenderness and expansion volume. The number of beating had significant effects on all sensory evaluation except volume. Response surface model showed that the optimal condition would be at least 15 days of soaking and 319 times of beating.

The purpose of the present investigation was to develop a novel method for cell immobilization. Aureobasidium pullulans cells were mixed with an alginate solution, and the mixture was extruded to form small gel beads as hydrated- immobilized cells. The beads were then placed at $-15^{\circ}C$ for 6-24 h to induce freeze-dehydration. The freeze-dehydration resulted in shrinkage of beads due to water removal reducing bead volume by 82% and bead weight by 85%. The dehydrated beads were successfully used for the production of fructo-oligosaccharides in a model reactor system. This study showed that bioreactor performance can be improved up to 2 times by the use of the dehydrated beads.

The levels of citrinin and monacolin K in ten commercial Korean Monascus fermentation products were determined. The products contained citrinin at levels ranging from 0.64 to $112.27\;{\mu}/kg$, with only 2 exceeding the limit of $50\;{\mu}g/kg$ set by the Korea Food and Drug Administration (KFDA). The levels of monacolin K ranged from 0.87 to 1,030 mg/kg, however 6 products contained monacolin K at levels lower than 500 mg/kg, the level required by KFDA to be claimed as a functional food. Therefore, many commercial Korean Monascus fermentation products should be considered safe, however many need to be improved before being considered as functional dietary supplements.
