Reducing plate-waste for school lunches is an important strategy to guarantee adequate nutrition intakes by students as well as to protect the environment. This study was conducted to determine dieticians' perception of no-plate-waste day. The subjects were dieticians at 203 schools in Seoul and Kyeonggi-do. Among them, 132 schools (78.6%) operated no-plate-waste day once a week, 6.9% once a month, 10.8% twice a week, whereas 17.2% did not operate at all. According to dieticians, plate-waste per student on no-plate-waste day (mean 49.1 g) was lower than that on an ordinary day (mean 79.2 g). The most popular method to advertise no-plate-waste day was to notify it on the menu board (52.4%), followed by notifying it on the dining hall and the school website. The most frequently used reward on no-plate-waste day was a gift snack (67.3%), followed by complimentary stickers, awards, and GPA. The most common side effect of no-plate-waste day was students' abandoning foods (45.2%), followed by rejecting food and simplified menu. The most frequent barrier was insufficient recognition of necessity (39.3%), followed by shortage of manpower or budget and students and teachers' resistance. The dieticians at 35 schools without no-plate-waste day answered that they did not operate it due to 'no need perceived' and 'no budget' (31.4% and 31.4%, respectively). Based on this study, government and society should promote the need to reduce plate-waste by students and teachers as well as school administrators.

Objectives: The purposes of the study were to assess wastes generated in school foodservice and to identify factors influencing the generation of plate waste. Methods: A survey was administered from November 18-30 in 2015 to dietitians and nutrition teachers that were employed in schools located in Gyeonggi province. A questionnaire file and on-line survey site link were sent to the dietitians and nutrition teachers by e-mail. A total of 622 dietitians and nutrition teachers responded and 594 responses were used for data analysis after excluding 28 responses with significant missing data. Results: Plate waste was the major part of food waste generated in school foodservice. Vegetable menus and soup/stews were discarded the most as plate waste. The dietitians and nutrition teachers perceived students' unbalanced diet and lack of appreciation of food as causes of the plate waste. Regarding waste management, they were concerned about environmental contamination by food waste and felt uncomfortable about discarding food. No plate waste day was the most frequently used plate waste reduction activity, followed by newsletters on plate waste reduction. Difficulty in getting teachers' support for dietary education during meal time was rated the greatest barrier to implementing the activities. To reduce plate waste, they perceived that students should understand the importance of environment conservation, teachers should supervise students' eating during meal time, students should be educated about proper portion, and foodservice staff should improve food quality. Conclusions: To improve students' intake and reduce plate waste in school foodservice, foodservice staff need to involve students in school foodservice and improve the palatability of meals, especially vegetable dishes. School nutrition teachers and dietitians should educate students about healthy eating and environment conservation and the school community needs to understand and support plate waste reduction and healthy eating in schools.

Clean plate education program was applied to change students' perception on food waste in the dormitory cafeteria of T campus G university that is located in Tongyeong, in which 408 students joined the program. From survey and food waste monitoring, it was found that clean plate education program was effective to change students' perception as well as action. Half students (50.5%) answered that their eating habit changed, and among them 30.1 % students left a little food on the plate and 13.1% students left no food behind. Many students become aware of the seriousness of food waste issue (84.5%), and 44.2% students were trying to reduce leftover. Food waste generation in cafeteria was 341.9, 576.1, 344.3g/capita/day in 2005, 2007 and 2008, respectively. And this shows that food waste generations were much less than national average data except 2007. Therefore we could conclude that clean plate education program was satisfactory to change students' perception on food and to change their action, and it could be an excellent new approach to resolve a social issue caused by food waste. In order to reduce food waste generation at dormitory cafeteria, food taste and diet should be improved and students' eating habits also should be changed. For this, a practical program like clean plate education should be organized.

This study investigated the standard recipe and changes in the quality characteristics of Chungkukjang-Kimchi (CKK) and evaluated its acceptance by elementary school students. The acceptability of Kimchi among elementary school students was evaluated by monitoring the plate waste rate. Chungkukjang powder was added to the Kimchi recipe at 0, 20, 40, 60% of the total weight of red pepper powder. The pH of the CKK decreased as fermentation proceeded, and the total acidity was $0.24{\sim}0.25%$ in all samples. The salinity of the CKK was 2.32%. The L color value was significantly lower in the treatment groups than in the control group. The b and a color values increased in the beginning, but tended to decrease during fermentation. In the sensory evaluation, there was no significant difference in appearance on preparation day, but there were significant differences on the 6th (p<0.05) and 20th days (p<0.01), with the highest scores observed in the 40% added group. Sourness increased significantly (p<0.001) during fermentation in all samples. There were significant differences (p<0.001) in crispness on the 3rd day among the treatment groups, and it tended to decrease as fermentation progressed. There were significant differences in flavor during the early stage (p<0.001), but there were no differences as fermentation proceeded. Overall acceptability was high in the 40% added group. Evaluation of acceptability by monitoring the plate waste rate in the school dining room showed that acceptability was highest in the 20% added group. Thus, it was concluded that acceptability among elementary school students was highest for CKK from the 20% Chungkukjang group.

This is a study on plate waste, management of the facilities and utensil, and for their hygenic management through the survey conducted at 106 enterprise located in Seoul institutional foodservice. Which were evenly divided into two groups; the white color and the blue color. The results are below: 1. Volume of food and menu were set in advance with no free choice. A campaign was launched to reduce food wastes. It was shown that free choice feeding was better in wastes reduction than none free choice feeding. 2. Hygenic management was relatively good in two groups. Machine and utensil usually sterilized by heating or disinfectant sterilization was performed at every using time or one time a day, but with no differentiation between two groups.

This study investigated the perception and attitude to leftover food at school food service by the questionnaire survey of the elementary school students in Gwangju area. The school food service satisfaction was neutral and school food service cost and quality was satisfactory. The dissatisfaction of school food service was shown as unkind staffs and a shortage for fruit and beverage. The kinds of leftover food were seasoned vegetables and kimchi. The reasons for leftover food were unfavorite food and the frequency was shown as once or twice a week. For the order of eating food, the subject first ate food they had tried. The highest kind of an unbalanced diet was beans and minor grains. To reduce food waste, many students perceived that tasty food, education by a class teacher in class that it could pollute environment and do us damage, recycling as livestock feed, 'No Plate Waste Day' organized by school would be a feasible method to reduce food waste. The nutrient intake of eaten food was significantly higher for all nutrients in the group receiving food waste education than the control group (p<0.001).
