  • The purpose of this study was to evaluate the microbiological quality of non-heat-processed foods and the effects of HACCP implementation. Here, cabbage salad and cucumber&onion salad were selected and we investigated HA(Hazard Analysis) by checking microbiological quality, time and temperature, pH, and water activity at each processing stage. Thus, the receiving of spices and dressings, washing and sterilizing, cutting, cooking, and serving stages were all considered CCPs. Before implementing HACCP, microbial analysis showed that standard plate counts and coliform counts were higher than standard levels in most of the raw ingredients of each menu, as well as during the production process. The microbiological quality of the utensils and employee's hands used during cooking indicated levels requiring direct management. Evaluations of falling bacteria-in the foodservice establishment work areas ranged from $2{\sim}12CFU/plate$. However, after HACCP implementation, microbiological levels improved to standard levels fly sanitation education. Also, the number of falling bacteria were lower than before implementing HACCP. Therefore, it is essential the foodservice operations make efforts to implement HACCP, so that microbiological hazard levels are lowered and hygienic status improved.

  • The objective of this study was to evaluate and improve the microbiological quality of HACCP application in school foodservice operations. The microbiological quality of foods and utensils were evaluated two times at each critical control point (CCP) with 3M petrifilm in five Daegu elementary schools. Two processes were evaluated: Heating process and after-heating process. The CCPs of the heating process were receiving, cooking and serving temperatures. The CCPs of the after-heating process were personal hygiene, cross contamination avoidance and serving temperature. After the first experiment, 31 employees of five schools were classroom educated, trained on-site, and pre- and post-tested on HACCP-based sanitation with the goal of improving the microbiological quality of the foodservice. Scores representing knowledge of holding, thawing, washing, food temperature, sanitizing and food-borne illness increased after education. In the heating process, internal food temperatures in the first and second experiments were higher than 74$^{\circ}C$, the holding temperature in the first experiment was less than 6$0^{\circ}C$. In the second experiment, the serving temperature improved to a satisfactory level. The microbiological quality in the second experiment improved by decreasing the time from cooking to serving. In the after-heating process, the ingredients were boiled before being cut in the first experiment. In the second experiment, ingredients were cut before being boiled, improving microbiological quality. Also in the second experiment, cooking just before serving food improved its microbiological quality through time-temperature control. These results strongly suggest it is essential to measure microbiological quality regularly and to educate employees on HACCP continuously, especially time-temperature control and cross contamination avoidance in order to improve foodservice quality.

  • In this study we investigated the elution level of lead (Pb), cadmium (Cd), arsenic (As), zinc (Zn), nickel (Ni), antimony (Sb), germanium (Ge), aluminum (Al) and hexavalent chromium (Cr6+) from 69 home-cooking utensils into a food stimulants. The results of migration testing according to the Korea standards and specifications for utensils, containers and packages showed values the allowable migrantion limits. Al was detected in all 7 utensil materials with the average concentration ranging from 0.002-5.989 mg/L. According to the migration conditions for (180℃, 30 min), the average concentration of Al in paper was 7.2 times higher than 25℃, 10 min (P<0.05). The results of migration testing at 180℃, 30 min were also below the allowable migrantion limits. When comparing with the provisional tolerable weekly intake (PTWI) of Al, the estimated weekly intakes (EWI) accounted for 0.000-0.045% for Al.

  • Purpose: This study investigates the necessary educational materials from the perspective of caregivers managing food allergies of preschoolers. Methods: An online survey enrolled 400 caregivers of preschoolers with food allergies. The study was conducted in July 2022, and data were analyzed using the IBM SPSS Statistics 25. Results: The caregivers of preschoolers with food allergies showed low food allergy knowledge. The highest percentage of incorrect answers were for items related to the cause (74.2%) and response (65.2%) to food allergies. Moreover, categorizing the levels of knowledge as high, medium, and low, we found that caregivers with younger children exhibited a better understanding of food allergies. Approximately 56.9% of subjects in the high class were caregivers with preschoolers under three years, whereas caregivers with preschoolers over four years comprised 43.2% of the high-class subjects. Regarding food allergy treatment, four questions measured how well the caregivers tended to the children. With higher levels of knowledge, caregivers were more likely to read nutrient information and check for food allergens. The caregivers of preschoolers who were clinically diagnosed with food allergies demonstrated a higher percentage of using separate ingredients and cooking utensils. Conclusion: This study shows how the caregivers' knowledge levels are critical in managing and treating food allergies among preschoolers. With caregivers' lower knowledge of food allergies and preschoolers younger than four years, self-diagnosis of food allergies and existing food allergies were not managed efficiently. Hence, customized education for caregivers is essential to improve their knowledge level regarding limiting foods that may cause allergies, reading food labels, and using ingredients and cooking utensils separately.

  • The objective of this study was to evaluate microbiological Quality of HACCP application in elementary school foodservice operations. Microbiological Quality of utensils and non-heated foods such as salad was measured two times at five elementary schools in Daegu. The two experimentations differed in that after the first experimentation employees were educated and trained on HACCP based sanitation standards with a goal of improving microbiological Quality of foodservice. Microbiological Quality, time, and temperature were evaluated at three critical control points (CCPs): washing and disinfecting, personal hygiene and non-cross contamination. Micro-biological Quality was assessed using 3M petrifilm to measure total plate count and coliform group. The first experimentation showed low microbiological Quality due to cross contamination of utensils and cooking gloves; high microbiological count of the garlic, powdered red pepper, and ginger; and not thoroughly washing and disinfecting vegetables. In the second experimentation, microbiological Quality was greatly improved by washing and thoroughly disinfecting raw ingredients and utensils, and using good personal hygiene. However, microbiological Quality of seasonings was still low. Immediate corrective actions were required in one of the foodservice operations that was assessed. These results strongly suggest that foodservice operations should address non-heated food Quality. It is essential to measure microbiological Quality regularly and continually train and retrain employees on hand washing and disinfecting raw ingredients. Further studies are needed to determine whether pathogens are present in raw vegetables and seasonings.

  • This was preliminary study that was to find out the developing point in military meal service to focus on seafood dishes that recently increased plate waste. This study was conducted to analyze menu patterns in military meal service. The result of this study was using to develop new seafood dishes in military meal service. On the basis of some findings, several developing points how to plan meals include many kinds of seafood dishes and to modify taste and cooking method that was more highly prefered by young military persons were suggested. This preliminary study findings were as follows: 1. Each meal was served cooked rice and 4 kinds of dishes(soup or stew, main dish, side dish and kimchi) 2. The seafood dishes was served as 28.6% in soup or stew, 35.0% in main dish and 36.4% in side dish of total serving of seafood dishes. 3. All of raw materials of seafood were supplied by frozen, several items were supplied dried material. Supplying seafood items were limited. Numbers of using seafood items were using 2.7 times per day. Laver and squid was most frequently used. 4. Seafood dishes were frequently serving in breakfast, especially seasoned & toasted laver was served 28.8% of seafood menu in breakfast because of convenience. 5. The nutrients contents of each dishes were as follows, the soup was $86.5{\pm}3.2kcal$ and $10.9{\pm}8.9g$ of animal protein, stew was $165.3{\pm}70.2kcal$ and $13.3{\pm}7.9g$ of animal protein. Nutrients content of other main dish and side dishes was different from 108.1kcal (in steaming dish) to 412.4kcal (in deep-fat frying dish) according to different cooking method. The highest animal protein dish that contented $18.9{\pm}5.1g$ of protein was pan-frying dish or grilling dish. Lowest one was $8.4{\pm}4.9g$ in braising dish. 6. Major cooking method of seafood was stew and the next was deep fat frying, stirfrying and braising. Pan-frying or grilling was seldomly used in military menu because of limitation of kitchen facilities and cooking utensils. On the basis of these findings, newely developing military seafood menus were focused on combination dish(such as seafood cooked rice or seafood fried rice) and many kinds of sauce that was applied to deep-fat frying dishes.

  • The purpose of this study was to investigate food sanitation status in elderly welfare facilities and assess the performance of food sanitation practices. Twenty elderly welfare facilities out of 85 located in Seoul with a capacity of fewer than 50 persons participated. The food sanitation status of worktable, kitchen utensils (knives, cutting boards, ladles, spoons), and tableware and bowls were examined by ATP bioluminescence. The results found that the ATP value of knife was the highest. Those of ladles appeared relatively higher than others. Meanwhile, the tableware and bowls, although washed everyday after meals, had the lowest ATP value. This study also conducted a survey on the food sanitation practices of 32 cooking employees in the 20 facilities. Fifty-six percent were in their 40s, and 53% had graduated from high school. More than half (66%) of them had no certification of cooking. Half of the respondents had worked for at least 5 years in food service facilities, and had received food sanitation training. Among them, 31% said they applied food sanitation training while working, and 47% responded the training was very helpful. The foodservice employees demonstrated good food sanitation practices. The results show that food sanitation performance of the workers significantly differed according to their age, education level, total work experience in food service facilities, chef certification, and prior food sanitation experience.

  • The purpose of this study was to investigate the kinds of Tteoks along with their recipes and ingredients occurring in Korean literature published before the 17th century. The reviewed sources included "Sangayorock", "Sasichanyocho", "Soowonjabbang", "Yongjechongwha", "Dongyoebogam", "Domoondaejak", "Geebongyouseul", "New-Guwhangchalyo", "Eumshickdimibang", "Joobangmoon", and "Yorock". Various types Tteoks could be classified into sic groups depending on their cooking methods as follows 23 kinds of Jjjin-tteoks, 8 kinds of Chin-tteoks, 24 kinds of Jijin-tteoks, 6 kinds of Salmeun-tteoks, 4 kinds of Guun-tteoks and 8 other types of tteoks. Within this paper, Tteok recipes and cooking characteristics are discussed and their ingredients, terminology and preparation utensils are reviewed. However some of the Tteok recipes are presently gone or have changed. From this study, we anticipate the development of useful recipes for those who are concerned about health and who seek longevity, and thereby to also advance the culture of Korean rice cakes.
