In order to control the quality and safety of cooked foods, production and holding methods of foods should be carefully studied and applied to the foodservice industry. Therefore studies on microbiological, nutritional, physicochemical and sensory quality are essential in this area. The purpose of this study was to evaluate the chemical and microbial qualities of cooked foods during preparation and holding From the results, the following guidelines should be adhered to give effective quality control when holding foods after cooking in foodservice institutions, as well as to provide quality foods when selling cooked foods at commercial establishments. Sauteed and simmered foods such as sauteed chicken meat & vegetables and simmered pork in soy sauce satisfy the standard for microorganisms till 1-3 hours of room temp. holding, 6-18 hours at 60$^{\circ}C$ steam table, and 12-18 hours at 80$^{\circ}C$ heating table.

To develop an antimutagenic functional diet, the foods that have shown anticancer activity were mixed to make ready-to-eat powdered diets. The diets were prepared with various kinds of powdered cooked cereals, cooked legumes, oil seeds and sea tangles, and freeze-dried vegetables. The antimutagenic effects of methanol extracts from three mixed diets were investigated in the Ames test, SOS chromotest, and in vivo supravital staining micronucleus assay in the mice.(omitted)

Objectives: This study examined the perception of the vegan trend of millennials and their future needs. Methods: This study was conducted online from June 21, 2021, to July 15, 2021, targeting 425 adult men and women born between 1980 and 2000. The contents of the survey were divided into four categories: general information, awareness of vegetables, awareness of vegan trends, and future needs for vegan trends. Results: Most respondents recognized the importance of eating vegetables and perceived vegetarianism and veganism as a lifestyle. Regarding the perception of the vegan trend, the highest response rate was 'The vegan trend is to be satisfied with my life regardless of other people', while the lowest response rate was 'The vegan trend is only a temporary fad'. The reasons for purchasing vegan products with high response rates were 'interest in the earth and environment', 'protection of animal rights', and 'thinking about health'. The type of vegan product wanted in the future was delicious food, and convenience level was in the order of 'completely cooked', 'half-cooked', and 'pre-processed'. Among the sustainable vegetarian types that millennials responded, 'semi-vegetarian', which can consume most animal products excluding red meat, showed the highest response rate. Conclusions: The positive perceptions about vegetables are expected to increase. Efforts should be made to develop convenient meals using vegetables and provide reasonable prices to expand vegetable intake.

For the purpose of improving the qualities of carrot, spinach and cooked rice, the effects of food height(0mm: H0, 5mm: H5, 10mm: H10, 15mm: H15) for microware blanching and reheating on physicochemical properties were investigated. In carrot blanching, color values of each treatment were not different, and cutting forces of microware blanching carrots were decreased as carrot height increased. In spinach blanching, the shape of orignal form was changed as height increased. In cooked rice reheating, H10 had the highest overall acceptance score. Physicochemical properties were changed by food hight of microwave blanching and reheating on food.

국내에서 소비되는 산채류에 대하여 thiamine분해능을 thiochrome 형광법과 Lactobacillus viridescens를 이용한 미생물법으로 측정하였고 페놀 화합물의 함량 및 갈색도와의 관계를 규명하였다. 더덕, 도라지, 토란대, 호박꼬지, 표고버섯, 도토리 전분 등은 thiamine분해능이 크지 않았으나 가지, 고구마 줄기, 고사리, 고춧잎, 취, 즉 등은 상당량의 thiamine분해능을 가지고 있었다. Thiamine분해능이 큰 산채류는 페놀 화합물의 함량과 갈색도도 높았다. 따라서 산채류를 식용으로 할 때는 thiamine급원식품과 함께 조리하지 말 것이며 조리 즉시 섭취하는 것이 바람직하다.

Subjects preferred cooked rice with beans, kalkooksoo(hot noodle), gomtang(soup with beef), bibimbap(rice with assorted mixture) to other staple dishes. However, preference for hashed rice or curried rice was very low. More than 50% of the subjects liked soybean paste soup and stew, and the ratio of elderly who liked Chinese cabbage kimchi was 68.7%. There was no significant difference in preference for pan-fried foods according to food materials in them. Subjects liked injolmi(waxy rice cake), shikhye(fermented rice drink) and coffee the most. Most subjects preferred plant foods like vegetables, legumes and seaweeds to animal foods. Preference of elderly for milk and yoghurt was reatively high; however, that for ham, butter and cheese was low. Elderly in Incheon liked roasted beef, beef soup and roasted pork the most.

Purpose: This descriptive study aimed to compare the perception of the acceptable foods for the neutropenic diet between nurses and patients by food type. Methods: The participants were 225 nurses working at chemotherapy wards and 71 patients in chemotherapy treatment. Data were collected with a self-administered questionnaire from January 2 to February 24, 2012, and analyzed with SPSS 12.0 program using descriptive statistics and the ${\chi}^2$-test. Results: Eighty-eight point eight percent of nurses and 76.1% of cancer patients thought the patients needed the neutropenic diets. The most important decisional criteria to determine dietary restriction was neutrophil count for nurses and food type for patients. The two groups showed significantly different allowance to raw fruits and raw vegetables, sterilized canned juice, fried vegetables, yogurt, uncooked tofu, salted fish, cooked fish, cooked shellfish, uncooked grain powder, jellified food, home-made bread/cookies, nuts including peanuts, instant coffee or tea and tea brewed. In general, patients were more permissive about the neutropenic diet than nurses. Conclusion: It is recommended to consider patients' preference as well as nurses' professional knowledge and publish standardized clinical diet guidelines for neutropenic patients with collaboration between nurses and patient representatives.

A study was performed to develop as a screening tool, the Simple Evaluation Questionnaire for screening Overweight Dietary Patterns in people in their 20's. We used the data from the 20 to 29 year old subjects who participated in the three surveys: the health behavior survey, the dietary habit survey and the food intake survey - as part of the National Health and Nutrition Survey of 1998. The 1,493 adults were classified into two body fatness groups, that of normal (including the underweight) , and the overweight (including the obese) on the basis of their relative body weight (RBW). When comparing general variables between the two groups, significant differences (11 variables) were found in gender, sadness/depression state, stress level, age, number of diseases, age when overweightedness started, maximum body weight, sleep length, presently a smoker, everyday smoking habits, number of alcoholic drinks in the past month, and the number of alcoholic drinks when dunk, as well as snacking frequency and fatty food consumption. There were significant differences between the two groups in the three variables of daily soup/kuk, pan fried fish/meat/poultry and cooked fish paste/ham/dried squid in terms of cooked food intake, and 11 variables of food size, cooked rice, stews, vegetables and kimchi at breakfast, panfried foods and beverage/teas at lunch, cooked rice and stews (liquid) at dinner, cooked fish paste/ham/dried squid at snacks and cooked fishpaste/ham/dried squid at snack between lunch and dinner. In terms of raw food intake, we observed significant differences (8 variables) in daily food intake and grains, grains/vegetables/fishes (shellfish) at breakfast, meat at lunch and milt at snack after dinner. After developing questions with indicators and analyzing the indicators by logistic regression analysis using 34 variables, including these 33, plus eating-out frequency, we chose 10 questions for the simple evaluation of dietary patterns for the overweight category, in order to give each one point each. Among them we assigned an additional point to one question and two points to another question. The average scores of the overweight and normal groups, as shown by the questionnaire developed, were 5.97 $\pm$ 2.36 and 7.36 $\pm$ 2.21, respectively. A score of seven points was selected as the cut-off point. We examined the sensitivity, specificity and positive predictive value of the questionnaire to the results of 49.3%,75.4% and 68.8%, respectively. The total score categorized as an overweight dietary pattern was 30.2%.
