Abstract
The characteristics of Jeungpyun were investigated with different milling methods of rice flour. The moisture content of Jeungpyun was similar to that of the rice flours. In the color of Jeungpyun, L-value was increasing but a and b-value were decreasing as its moisture content was increasing. The analysis on the texture of Jeungpyun showed that Jeungpyun by dry milling indicated the higher value in hardness and the lower value in springiness, cohesiveness and chewiness than Jeungpyun by wet milling. The test of the sensory characteristics for Jeungpyun showed that whiteness, moistness, springiness and chewiness was higher for Jeungpyun by wet milling. But the softness was lower. Overallquality of Jeungpyun by wet milling was higher than Jeungpyun by dry milling. Generally, Jeungpyun prepared by Pin-mill was the best in quality In particular, Jeungpyun by wet milling was better for the added 80% of water and Jeungpyun by dry milling was better for the added 100% of water.

Abstract
This study is a result of the experiments to determine the optimum conditions of salting of Chinese cabbages for making tasty Kimchi. For the experiments, various methods of salting of Baechu were set up and the best method of salting had prepared Kimchi to investigated the best salt kind. In the two best results by method of salting salt kind, were investigated for salting time of Kimchi. There were certain amounts of Kimchi had prepared for each case of the combinations of the three conditions. Every case of Kimchi was refrigerated and was evaluated by sensory tests. In the salt concentration, pH and acidity of the Kimchi were measured. The results are as follows; In three cases of Kimchi, for salt concentration, level of 2.4-3.0° was maintained in Kimchi solid from the beginning to the end, while it was high in the beginning and gradually lowered in Kimchi liquid. The level of pH in both solid and liquid of Kimchi quickly dropped at the beginning of fermentation period and turned slow as time passed. And the level of acidity was increased little bit in the beginning, but it suddenly multipied until the third day of preservation. Since then, it had increased gradually thereafter as it was before. This experiments show that Kimchi can be the best taste in the case of Chinese cabbage soak in brine- free natural salt are kept for five hours.

Abstract
This study was carried out to investigate the free amino acid content, the free amino-nitrogen content and minerals such as Ca, P and Fe of chicken bone stock. The results were as follows. 1. In chicken bone stock, glutamic acid was the most abundant amino acid, lysine, alanine, cysteine and glycine were followed oderly and these free amino acids seemed to be the most intensive flavor compounds. 2. The free amino acid-nitrogen content of chicken bone stock was increased after 3 hours boiling and began to decrease after 4 hours boiling. 3. After 3 hours boiling, Ca, P were 5.0 ㎎/100 g chicken bone and 42.5 ㎎/100 g chicken bone, respectively and began to decrease after 4 hours boiling. The ratio of Ca:P was about 7.8. Fe was increased after 4 hours boiling and began to decrease after 5 hours boiling. These results revealed the low effectiveness of Ca, P and Fe utilization of chicken bone stock, because of the very low extraction of minerals. But these results revealed the significant correlation of free amino acid, free amino-nitrogen contents and brothy flavor. So chicken bone stock on heating at 90-95℃ for 3~4 hours seemed to be the most intensive brothy flavor.

Abstract
6 Central commissary and 2 conventional school foodservice operations were assessed in terms of time-temperature relationship and microbiological quality, and monitoring control methods were identified through hazard analysis during the phases of prodution and distribution. 2 conventional schools from Seoul and 6 commissary schools from Kyungkido were participated in the survey. Meals produced in central commissary were distributed to satellites, therefore delivery practices of foods were identified as critical. Microbiological test results for commissary and conventional schools revealed that microbiological quality of foods was mainly related to time-temperature management, types of food, and equipment sanitation not to the foodservice system used. Time-temperature profiles at temperature danger zone (7.2∼60℃) observed were to be related to the following sanitary practices: cooked vegetables were held at temperature danger zone for relatively longer delayed time (15-38℃: 15-226 min, 7-60℃: 75-226 min), and same results were observed for deep-fat fried cutlets (15-38℃: 15-151 min, 7-60℃: 33-151 min). Menu items with various ingredients and frequent contacts with hands and equipments during the production flow were held at temperature danger zone for longer delaying time than other menu items with brief prodution stages. Based on hazard analysis critical control points, microbiological quality was collectively affected by time-temperature relationships, equipment sanitation, proper cooking methods, and sanitary management competencies of dietitians. Microbiological test results of working equipments and surface of dishes and trays showed that immediate action should be taken. Cutting boards used in central kitchen were also showed similar results of potential dager of cross-contamination. Effective sanitary control methods were urgently needed.

Abstract
The survival and growth of Staphylococcus aureus and Listeria monocytogenes in fish homogenates (flounder, shrimp and oyster homogenate) and tryptic soy broth (TSB) were tested during storage at simulated ambient (35℃), refrigerated (5℃) and frozen (-20℃) temperarure. A similar growth pattern of S. aureus at 35℃ was observed in fish homogenates and TSB. Survival of S. aureus decreased at refrigerated or frozen temperarure and that was greater at -20℃ (0.3-1.2 log reduction/6 weeks) than at 5℃ (1-1.6 log reduction/3 weeks). Viable cells of L. monocytogenes increased rapidly at 35℃ in flounder homogenate, shrimp homogenate and TSB but after a prolonged lag period in oyster homogenate. During 3 weeks of storage at 5℃, the levels of L. monocytogenes increased 3.8-5.0 log cycles in flounder homogenate, shrimp homogenate and TSB whereas levels increased 2.2 log cycles in oyster homogenate. Viable cells of L. monocytogenes during 6 weeks of frozen storage decreased 1.5-1.8 log cycles in flounder homogenate, shrimp homogenate and TSB while decreased 2.8 log cycles in oyster homogenate.

Twenty five cooking recipe with yam (Dioscorea japonica Thunb) have been developed and their hypoglycemic effects on diabetic patients were investigated. The results of the sensory evaluations revealed that the tested recipe were in good scores (overall acceptability scores 3.30-4.33) except Chojuli. The 10-panel members indicated that the yam cookings were more acceptable when they were cooked with other vegetables. Twenty seven diabetic patients were entered in a general hospital during the 2-month experimental period and they were allowed to consume the diet with yam cooking dish, 75g of yam a day. The fasting blood glucose and 2-hour postprandial blood glucose levels were determined. The diabetic patients who consumed yam showed the lower blood glucose levels than those patients who were controlled with the hospital diet only. The hypoglycemic effects of the yam were more evident in the patients who were injected with insulin. The constant lowering effects of blood glucose levels were observed in the normal subjects who had taken the yam cookery, leading to that one subject who started with a low blood glucose level must stop the yam consumption after 10 days.

Abstract
This study was conducted to examine the effects of fish sauces from shrimp and anchovy and chitosan on the changes in pH, acidity, texture, and pectin fraction during Kimchi fermentation. Also, we conducted sensory evaluation on the textural properties of various Kimchis. The results were as follows: During fermentation, pH was decreased in the order of fermented anchovy sauce, fermented shrimp and control. And acidity was increased in the same order. But the addition of chitosan retarded the decrease in pH and increase in acidity. The compression force of various Kimchis during fermentation was decreased in the rder of fermented anchovy sauce, fermented shrimp, control and the addition of chitosan. During fermentation, hot water soluble pectin (HWSP) of control, fermented shrimp and fermented anchovy sauce increased whereas HCI soluble pectin (HCISP) in there treatments decreasd. On the while, HWSP decreased and HCISP increased by addition of chitosan. Sensory scare for the texture parameters such as hardness, crispness and chewiness of various Kimchis after the 3rd and 5th days of fermentation showed that hardness, crispness and chewiness were higher in chitosan treatment than in other treatments. The pH and acidity, compression force of Kimchis were appeared to be most highly correlated with crispness, showing that pH and compression force gave positive correlation and acidity gave negative correlation with crispness respectively. From the above results, chitosan addition was observed to infuluence the textural properties of Kimchi and their pectic substance.
