This study was conducted to elucidate the characteristics of equine meat traits and to evaluate the utilization of dried-citrus pulp abundantly produced in Jeju Island as feed ingredient in the diet of finished meat horses. Treatment groups consisted of wheat bran (A) and the dried-pellet mixture of citrus pulp (20%) and wheat bran (80%) (B). Feeding of agricultural by-products were 2 times in a day at the level of 1.5% of body weights. Water and dried-grass forage was not restricted. The average daily gain was similar in both groups. Feed conversion of treatment B showed lower level than that of A. Carcass rate of B was relatively lower than that of A, but meat yield grade of B was higher than that of A. For meat color traits, $L^*$ of B was lighter than that of A, and $b^*$ of group B was lower than that of group A. From the analysis of physical characteristics of equine meats, shearing force had decreased in the treatment B but the levels of drip loss and water holding cavity had increased in the treatment B compared to A. The level of crude fat is lower in the treatment B than the treatment A. For the mineral contents, the treatment B showed higher levels of Ca, K, Mg, Cu and Mn than that of A. For the fatty acid contents, the treatment B showed increased levels of stearic acid, oleic acid, eicosenoic acid, and arachidonic acid compared to A. Consequently, these results suggested that dried-citrus pulp might be utilized as replacement material for equine forage.

This study was conducted to provide strategies for the reduction of plate waste and prevention of plate waste reuse in foodservice operations. To achieve these goals, we surveyed the entrepreneurs of foodservice operations, professionals in the field of foodservice management and food safety, and public officials working for food safety enforcement about their perceptions and strategies on plate waste management. The professionals' survey indicated that definition of plate waste needed to be clear for understanding. Also Korean food culture insisting on abundance and variety table settings, foodservice owners' demands for cost reduction, and foodservice workers' insufficient safety perceptions were indicated to bring forth the practice to reuse plate waste. The effective ways to control plate waste management were systematic educational supports for Korean food culture upgrade among consumers and improvements of safety perceptions among owners, as well as workers. Also small portion size was needed to reduce plate waste.

The data was collected from 249 highschools in Seoul. The results are as follows; Those surveyed highschools were established as 1 national, 74 public, and 174 private institution. Highschools were classified as 176 academic, 66 vocational, and 7 specific purposed institution. Students were organized as 70 boys', 23 girls', and 41 coeducational highschools. Most highschool started contract-managed highschool foodservice from 1999 and the period of foodservice contract was most 3 years and the operation styles in food distribution were 96 classrooms, 105 dining halls and 17 classrooms combined dining halls. The scale of contract foodservice management companies was 63.1% small and medium and 36.9% large enterprises. The surveyed highschools had the average meal price 2,141 won per meal and they had 1,518 pupils on the register. The participating rate to the foodservice was 68.5%. The facilities investment cost of the contract foodservice management company was 179,204,230 won for private institutions and was 138,119,010 won for national&public institutions. The period of the contract was 3.22 years in private institutions, which was significantly higher than national&public institutions which showed 2.85 years. The commissary foodservice schools had higher facilities investment cost than conventional foodservice schools. Classrooms foodservice had higher participating foodservice rate than Dining halls. The investment cost for facilities showed high in order of girls', boys', and coeducational high schools, and the number on the register and the number participating in the foodservice showed high in order of boys', girls', and coeducational high schools. The number on the register showed the highest in academic and vocational schools, specific purposed institutions in sequence, and the number participating in the foodservice showed high in order of academic schools, specific purposed institutions and vocational. However, the participating foodservice rate showed high in specific purposed institution, academic and vocational schools in order, and the meal price, the investment cost for facilities showed high in specific purposed institution, academic and vocational schools in sequence. Regionally, the district south of Han river had the average meal price 2,266.13 won, which showed higher in the eastern part which had 2,033.33 won. The western part had the average investment cost for facilities of 233,331,060 won, and the central district 126,137,140 won. The number on the register showed 1845.68 in the eastern part and 1308.00 in Dong-Jak area, that had clear differences among areas. When the period of the contract went longer, the investment cost for facilities had a tendency to increase. The significant differences were existed among meal price, the investment cost for facilities, the number on the register, the number participating in the foodservice, and the participating foodservice rate. The investment cost for facilities had increased according to the number participating in the foodservice and the participating foodservice rate. And the large enterprises showed higher participating foodservice rate than the small and medium enterprises.

Effect of packaging and storage methods for enhancing the shelf life and improving the postharvest quality of lettuce (Lactuca sativa L.) was studied during high temperature period. Lettuces were packed using four packaging and storage types: (A) plastic box container (control); (B) plastic box container covered with high density polyethylene (HDPE) film; (C) plastic box container with lettuce wrapped in linear low-density polyethylene (LLD-PE) film; and (D) plastic box container with lettuce with its stem. The quality parameters, such as fresh weight loss, SPAD value, and appearance of lettuce were investigated. The lettuce wrapped with LLD-PE film inside the plastic box container showed the lowest weight loss, highest SPAD value and best appearance compared to those exposed to the other packaging and storage methods during the three-week storage at $2^{\circ}C$. The results indicate that the marketability of lettuce can be optimized if proper packaging and storing is adopted. Prolonging the freshness even on low temperature storage will increase the potential of its sale ability in the domestic market even during summer season.

To study the nutritional and health status of the elderly in Songnam, the anthropometic measurments, fat composition of body(FAT), blood pressure(BP) and blood test for analyzing biochemical indies of the elderly in seongnam were carried out in 338 free-living elderly (161 men, 177 women) aged from 58 to 92. Anthropometric measurements and blood pressure were assessed, and body fat was analyzed by BI(Bioelectrical Impedence) method. Biochemical measurements including blood glucose(BG), GPT, serum total cholesterol(TC) and albumin(AL) were analyzed. Average heights of the subjects were lower than the standards established in the Korean Recommended Dietary Allowances, and average weights were similar to the standards. FAT were significantly higher in women(36.4%) than men(27.7%), and both groups showed higher values than the reference. Mean systolic BP levels of men and women were 153.3mmHg and 153.7mmHg, and diastolic BP levels were 87.5mmHg and 86.0mmHg, respectively, and there were no significant differences between the sex. Mean BG levels of men and women were 115.9mg/㎗ and 123.7mg/㎗, respectively, and there were no significant differences between the sex and among the age groups. Mean GPT levels of men and women were 19.4unit and 18.1unit, respectively, and women older than 75 years showed significanly low levels of GPT compared to other women's age groups. Mean TC levels of men and women were 186.0mg/㎗ and 206.6mg/㎗, respectively, and significantly higher TC levels were shown in women than men. Mean AL levels of men and women were 4.8g/㎗ and 4.8g/㎗, respectively, and men aged 50 ∼ 64 years showed significant high AL levels compared to other age groups of men. It was suggested that nutrition education program was a good way to improve health status of the elderly.

The purpose of this study was to observe the effects of high-carbohydrate (HC) diet, high-protein (HP) diet and high-fat (HF) diet with a normal diet (N) on diet-induced thermogenesis (DIT) in healthy Korean women. The four isoenergetic test meals consisted as follows: HC (75$ \% $ energy from carbohydrate, 10$ \% $ from protein and 15$ \% $ from fat), HP (10$ \% $ energy from carbohydrate, 75$ \% $ from protein and 15$ \% $ from fat) HF (15$ \% $ energy from carbohydrate, 10$ \% $ from protein and 75$ \% $ from fat) diet and N (65$ \% $ energy from carbohydrate, 15$ \% $ from protein and 20$ \% $ from fat) diet. Fasting and postprandial thermogenesis were measured after each test meals in eight subjects by indirect calorimetry for 3 hours. Fasting and postprandial serum glucose, insulin and triacylglycerol contents were also measured for 3 hours. DIT were 10.4$\pm$3.2 for HC, 12.7$\pm$0.5 for HP, 6.9$\pm$2.8 for HF and 8.7$\pm$4.8 for N diet as a percentage of the energy load. DIT of HP was greater than HF significantly, but had no differences with HC and N Integrated areas under the curves ($ \delta- $-AUC) of plasma glucose and insulin were significantly higher for HC compared to HP, HF and N diets. $ \delta$-AUC of plasma triacylglycerol was significantly higher for HF compared to the other test meals. In conclusion, intake of protein rich meal stimulates postprandial energy expenditure, but has no relation between DIT and insulin response, body composition.

The purpose of this study was to observe the effects of fiber free control diet (CD), cellulose diet (CED) and pectin diet (PTD) on diet induced thermogenesis (DIT) in healthy Korean woman for 3 hours. The three test diets were as follows: CD (carbohydrate intake: 63.4% of energy, protein intake: 14.0% of energy and fat intake: 25.8% of energy), CED (carbohydrate intake: 62.5% of energy, protein intake: 14.0% of energy and fat intake: 26.1% of energy) and PTD (carbohydrate intake: 62.7% of energy, protein intake: 14.0% of energy and fat intake: 26.2 of energy). Groups were served 10 g of cellulose for CED and 10 g of pectin for PTD, respectively. DIT was measured at fasting state and at 30, 60, 90, 120, 150 and 180 min after consuming each diet. The mean age of all subjects was $22.3{\pm}1.9$ years. Body weight was $52.5{\pm}8.6$ kg and body mass index was $20.6{\pm}2.7kg/m^2$. Preprandial resting energy expenditure was $0.79{\pm}0.02kcal/min$ and postprandial DIT were $14.05{\pm}0.62%$ for CD, $9.33{\pm}0.62%$ for CED, $11.07{\pm}1.35%$ for PTD as a percentage of the energy load. DIT of CD was significantly higher than those of CED and PTD. There was no significant difference in postprandial change in body temperature after consuming each test diets and the sympathetic nervous system activity measured by heart rate was significantly higher in CD than CED and PTD (p<0.05). With this study, it can be concluded that CED and PTD have significantly lowered in DIT (p<0.05). We didn't show the correlation of the factors that relate in DIT; thus, further experiments on that matter should be followed.

The nitrogenous compounds in the muscle extracts of cultured and wild olive flounder, Paralichthys olivaceous, were analyzed. The analyzed coumpounds were extractive nitrogen, free amino acids, oligopeptides, ATP and its related ompounds, quaternary ammonium bases, and guanidino compounds. The distribution pattern of these compounds in cultured and wild fish was found to be very similar. Although the ATP and its related compounds and creatine in the muscle of cultured fish were slightly abundant than those in the muscle of wild one, the extractive nitrogen, total free amino acid, oligopeptides, and TMAO were found to be slightly rich in the muscle of wild fish than those in the muscle of cultrued one. The moisture content of cultured fish was relatively lower but the protein and fat contents of cultured one were higher than those of wild fish. However the differences in the proximate composition, extractive nitrogen and nitrogenous compounds between two fishes were not significantly different.

The objective of this study was to analyze quality changes during storage of fresh-cut produce (leafy vegetables and condiment vegetables) as a function of packaging and storage temperature. Fresh-cut produce was washed using a three step cleaning process and was packed in vacuum packaging (green onion, hot pepper, onion, baechu) and perforated film packaging (buchu and perilla leaf). The effects of packaging method and storage temperature on quality of fresh-cut produce were determined by analyzing total plate counts, E. coli, coliform groups, moisture content, pH, Aw, surface color, and exterior quality during storage at 4 and 10$^{\circ}C$. According to the results, surface color change and microbial growth were delayed during storage at 4$^{\circ}C$. Additionally, E. coli was not detected during storage. Generally, moisture content decreased in the perforated film packaging. Changes in surface quality such as skin browning, softening of tissue and chlorosis at 4$^{\circ}C$ were inhibited, whereas rapid vacuum annealing and changes in color and flavor were observed in the sample stored at 10$^{\circ}C$. The result indicated that overall quality of the fresh-cut produce at 4$^{\circ}C$ was well maintained. The perforation in packing materials did not significantly increase the number of microorganisms on buchu and perilla leaf. The proper packaging methods and temperature may beneficial effect on microbial safety, quality and thus result in longer shelf-life fresh-cut vegetables during distribution.
