Food waste left by patients in hospitals is an important indicator of the nutritional adequacy of the patients' diet and of their satisfaction with food. Food wasted by patients or staff in hospitals is one of the most serious problem in hospital foodservice systems. The purpose of this study was to evaluate the disposal practices of food waste in hospital foodservices for providing basic information for an efficient solid waste management. This approach was achieved using a variety of qualitative and quantitative information including general food waste practices and measurement of food waste left by patients and staff in 20 hospital foodservices. The average food wasted by patients and staff per day was 402.20kg and 206.98kg respectively, being total food waste of 578.08kg per day. The mean plate waste of a staff was 115.95g, which was much lower than that of a patient (221.03g). As means of food waste treatment, most hospitals(60%) are using animal feed, followed by means of collection by contracters(15%) and disposal of waste collection after condensing. An average monthly cost for disposing food waste was 915,000 won and average 138.58 minutes were spent to dispose food waste in hospital foodservices.

The purpose of this study was to gauge customers' satisfaction with the hospital, university, factory, and office foodservices from a contracted provider. Importance-performance analysis (IPA) evaluations were conducted. Questionnaires were returned from 1,808 customers in 46 foodservice locations. The average total scores of the importance and performance of seventeen quality characteristics were 4.14 and 3.23, respectively, on 5-point scales. The average total score of gap (gap = performance - importance) was -0.92. Analysis of significant difference according to the type of foodservices revealed that, hospital foodservices had more items with significant high scores than those of other groups in the average total scores concerning importance (p<0.01) and performance (p<0.01). The average total scores of gap showed no significant difference. Significant differences were evident in the food and personal service dimensions, and the scores of hospital foodservices trended significantly higher than those of other groups. Importance-performance analysis (IPA) analyses for hospital foodservice implicate 'variety of menu', 'cleanness of dishes', and 'taste of food' as items requiring prompt attention and improvement.

The purpose of this study was to investigate effectiveness of sanitization on raw vegetables not heated in foodservice operations. Microbiological examinations of food materials and cooked food with leek Gukgalli were performed in 2 HACCP-implemented foodservices (A and B) appointed by Food and Drug Administrations, and in 2 other foodservices (C and D) not implemented HACCP. 'Washing and sanitizing raw vegetables' were monitored as CCP at A and B foodservices but only washing has been done in pre-preparation at C and D foodservices. Aerobic plate counts of received leek in A and B foodservices were above $10^7$ CFU/g indicating very poor microbiological quality. After sanitization treatment (soaking for 5 minutes in chlorine water: chlorine density 50〜100 ppm), its aerobic plate counts decreased to 7.06×$10^5$ CFU/g (A foodservice) and 4.31×$10^5$ CFU/g (B foodservice), coliform and faecal coliform were not detected. With this result, the effect of microbial reduction by sanitizer was conformed. But, the conditions of leek were still not acceptable by microbiological standards for ready-to-eat foods. After three more times of rinse has been done, the microbial conditions of leek became acceptable. In C and D foodservices, aerobic plate counts of leek showed decreasing trends by 2〜4 times of washings but microbiological quality of leek after pre-preparation were unacceptable by microbiological standards for ready-to-eat foods (C foodservice: 3.58×$10^5$ CFU/g, D foodservice: 1.29×$10^9$ CFU/g). For the prevention of foodborne illness, sanitizing raw vegetables should be performed during pre-preparation of non-heated foods.

The purpose of this study was to identity the probability of cross-contamination from the environment. For this, we examined foodservices at 20 universities/colleges for microbiological analysis of their working facilities and environment as well as their preventive equipment against cross-contamination. Seventy percent of the 20 foodservices were found to maintain one unified working area, which suggests high probability of contamination of food/utensils/equipment in the cooking area by pre-preparation or dish washing. According to the microbiological analysis, the hygiene acceptance ratio of working facilities in the clean zone was 70%, which was higher than the average 45% hygiene acceptance ratio of working facilities in the contamination operating zone. There was a significant difference in the total plate count (P<0.001) and coliform count (P<0.01), which demonstrates that work tables in the clean zone were in a good state compared to those in the contamination operating zone. In the contamination operating zone, refrigerator shelves had a high probability of cross-contamination. Regarding the floor surface and airborne microbes, cooking areas which should be maintained as clean zones had higher cross-contamination probability than those in the contamination operating zone. So corrective actions such as cleaning and sanitizing, keeping dry floors, lowered temperature and humidity, shoe disinfecting facilities, and checking concentrations, are necessary to manage floor surfaces and airborne microbes in the cooking area.

The purpose of this study was to set new guidelines for adenosine triphosphate (ATP) bioluminescence hygiene monitoring of distribution trays at children's foodservices. Five dietitians visited 223 foodservices (95 institutional, 128 small) to examine whether they adhered to the norms of 'Keeping distribution tray sanitary by washing/sanitizing' and 'Performing food distribution in a clean and appropriate way'. In this visit, dietitians swabbed 100 ㎠ area of the distribution trays twice, once for obtaining ATP measurements and the second time for Aerobic Plate Counts (APC) using 3M Petrifilm Plates. Chi-square test and ANOVA were applied using SPSS 23.0 software. SPSS 23.0 was used to conduct graphical and statistical analysis of the raw data of ATP measurements, which were further transformed by a Box-Cox transformation. The mean of APC from all the subjects inspected was 3.8×10²±2,102.0 CFU/100 ㎠. A total of 208 (93.3%) trays were observed within the acceptable limits of APC (Pass<5.0×10² CFU/100 ㎠). APCs taken at institutional foodservices showed significantly lower levels (1.4×10²±600.0 CFU/100 ㎠, P<0.01) compared to the small foodservices (5.5×10²±2,718.7 CFU/100 ㎠). No significant differences were observed between the two groups in ATP measurements and in the performance rate of 2 checklist items. As against the 93.3% APC adequacy from the total subjected inspection, total ATP adequacy (Pass≤300 RLU/100 ㎠) was only 71.7%. Therefore, more practical guidelines should be prepared for the assessment of the hygiene of distribution trays. In the graphical and statistical analysis, levels below 250 RLU/100 ㎠ was considered 'Pass', while equal to or greater than 350 RLU/100 ㎠ was considered 'Fail' for distribution trays.

The purpose of this study was to evaluate the meal pattern and the nutritional balance in university foodservices of Seoul. The survey was conducted using a questionnaire with 317 students at five different cafeterias that served 23 meals. We weighed all the meals offered by the university foodservices, separated the foods, and calculated their nutritional content using a computer program $\ulcorner$DS24$\lrcorner$. We also checked the dishes and those amount students consumed from the menu. The results of this study is summarized as follows. : 1) The most prevalent menu patterns included rice, soup, two side dishes, and kimchi. 2) Most nutrient contents per meal in a given menu was lower than one third of the recommended dietary allowance(RDA). 3) The mean energy content for the amount of rice that was served was 399㎉, for the side dish, it was 107㎉, and for the kimchi, it was 9.9㎉. 4) The number of total dishes and side dishes was five and two, respectively. The dietary variety score was 16.7, and the dietary diversity score was 3. 5) The mean energy intake by students at self-operated managements were 545㎉, and at one contracted management, the energy intake were 494㎉. Both of them did not serve enough to meet one third of the RDA. Nutrient adequacy ration(NAR) was 0.4∼0.9, and Index of nutritional quality(INQ) was above 0.9 for most nutrients with the exception of calcium and vitamin B$_2$.

The purpose of this study was to measure patients satisfaction and expectation with hospital foodservices, and thereby identify areas for improvement and provide basic data for the introduction of total quality management with hospital foodservices. This survey was carried out on 383 hospitalized patients of 7 hospitals in Deagu, Busan, Changwon with 350 beds to determine the quality satisfaction with foodservices. The subjects were 50.5% male and 49.5% female. 62.6% of the subjects were over 40 age, 31.4% were only educated to middle school or below, 28.3% were hospitalized for 7-14 days. The mean score for taste of diet was 2.79, temperature 3.23, appearances 2.96. Most subjects agreed with following foodservice characteristics that meals of movement (4.03), dress of employees (3.84), kindness of employees and meals arrived exactly the same time every day (3.47) and cleanliness of foods (3.34) and dishes (3.33). The unsatisfied quality attributies were information provide (2.82), variety of the meals (2.91), mixing of meals (2.95), the opportunity to meet with a dietitian (2.97) and prompt dealings with meal complaints (3.01). Most subjects expectation that the decrease the multiple of menus, increase provide of fruits in hospital meals and selective menus in hospital foodservices operations. In conclusion, it would seem to be desirable that hospital foodservices departments introduce selective menus, quality assurance, and increase the meal rounding of dietitians in the patient foodservice.

In this study, a survey was conducted on the development of meal kits for children's foodservice to increase the convenience of the cooking process. It was performed among the foodservice managers in the 141 children's foodservice facilities registered in the Center for Children's Foodservice Management about meal-kits in Changwon areas. The survey results were analyzed according to the children's foodservice scale type. The biggest problem in a foodservice system was "difficult to purchase food ingredients directly every week" (38.4%) in small-scale children's foodservices, and "difficult to use the served menu without modification" (38.2%) in institutional children's foodservices (P<0.001). The most important factor when choosing the meal kit was "quality" (41.1%). Respondents on having an experience with using the meal kit were low at 34.8%, and the reasons for not using the meal kits were "expensive" (67.3%) and "not fresh food ingredients" (18.4%). The main reasons for not using children's foodservice meal kits were "expensiveness" (64.4%) and "necessity of adding disinfection process" (16.1%). Most of the reasons for not wanting to use children's foodservice meal kits were that they did not trust the safety of the meal kits. The use of meal kits in children's foodservices may reduce the preparation process and increase the efficiency of foodservice although the safety and quality of meal kits should be guaranteed. The appropriate hygiene management standards need to be set, and HACCP should be applied to develop meal kits for children's foodservices.
