The objective of this study was to investigate the physicochemical, microbiological and sensory properties of food additive-free grilled pork products manufactured using loin (T1), tender loin (T2) and ham (T3). The samples were heated for 30 min at $60^{\circ}C$, and then 50 min for $150^{\circ}C$. After cooling, vacuum packaged grilled pork samples was stored at $4{\pm}1^{\circ}C$ for 40 days. The pH values of grilled pork samples ranged from 5.92 (T1) to 6.10 (T3) at the initial storage time, and from 6.28 (T1) to 6.60 (T3) after 40 days. The water holding capacities(%) was $85.99{\sim}93.24%$ for T1, $95.26{\sim}93.89%$ for T2 and $89.11{\sim}94.67%$ for T3, all of which were slightly higher than those of other pork products. The shear force values of T2 were significantly higher(p<0.05) than those of the other pork products throughout the storage period. The TBARS and VBN values of T2 were significantly higher(p<0.05) than those of T1 and T3. With regard to microorganisms, all grilled pork samples was in good condition, showing $1.93{\sim}3.48\;log_{10}$ CFU/g via total plate counts, and $1.74{\sim}3.48\;log_{10}$ CFU/g far lactic acid bacteria throughout the storage period. Regarding sensory evaluation, the scores of overall acceptability in all products were above 5.0 points through 40 days of storage.

BACKGROUND/OBJECTIVES: This study examined the associations between food consumption frequency of Korean adults and self-perceived chewing difficulty, using the food frequency questionnaire (FFQ, 112 items) from 2013-2016 of the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: Subjects were divided into not difficult in chewing (NDC) and difficult in chewing (DC) groups, with 24.17% being classified into DC. Males and females consumed 35 and 37 items less frequently than the other sex, respectively. Due to the remarkable gender difference in food consumption, gender-stratified one-sided survey regression analysis was performed after adjusted for the effect of age, household income, and self-rated health status. RESULTS: Thirty-four items of FFQ were significantly less consumed by the DC group. Females exclusively consumed less beverages and alcohol while males showed the same for fruits and milk·dairy products. Consumption frequency of 8 items such as steamed potatoes·grilled potatoes, stir fried beef, other kimchi·fresh vegetable kimchi, orange, sour pork·pork cutlet, tteokbokki and green tea were significant only in males. In contrast, 17 items including cooked rice with other grains and legumes, boiled egg·steamed egg, Korean cabbage kimchi, banana, and tofu stew·soft tofu stew were significant only for females. Finally, items that showed significance for both were 9 items including loaf bread, ready-to-eat cereal, steamed sweet potatoes·grilled sweet potatoes, stir-fried lotus roots·stir-fried burdock, green laver salad·brown seaweed salads, apples, tomato·cherry tomatoes, squid (raw, dried shredded, boiled, stir-fried), and curd type yogurt. CONCLUSIONS: Findings in this study suggest chewing difficulty may be an important nutritional issue that has to be dealt with for healthful food consumption, with distinct interest of gender.

Objectives: This study was designed to find out factors that are needed to be improved for the Buddhist training environment of Sramanera Sramanerika monks, who have been newly adapted for their life style after becoming a monk, and to provide basic data for the development of the standard diet in Buddhist temples. Methods: A self-administered questionnaire was applied to 365 Sramanera Sramanerika monks at 11 Buddhist monk universities. The questionnaire was designed to investigate their dietary habits, dietary evaluation, satisfaction of food service, and food preferences. Results: The study population consisted of 52.6% men, and 47.4% women. The subjects who had a vegetarian diet before joining the Buddhist priesthood were 27.7% women, and 13.5% men (p<0.01). 42.2% of the total subjects felt that they are healthy now and 19.4% felt weak. The most difficulty of dieting adaptation as soon as entering the priesthood was the strict diet rules (42.9%). The subjects considered health or nutrition (40.0%) highly when having meals. 94.8% women, 84.1% men ate breakfast every day (p<0.001). Women (55.4%) frequently ate snacks more than men (26.6%) (p<0.001). The results of the dietary evaluation indicated that the intake of milk, soy milk or dairy products and beans or tofu received lower than 3 points and women had lower point result than men (p<0.001). Foods with higher preference were grilled mushrooms, grilled laver, miso stew, sweet and sour mushrooms, steamed tofu with seasoning. Conclusions: Women were more interested in their health than men but they also required to improve the nutritional eating habits. It appeared that the lower intake rates of the calcium containing food (milk and dairy), and proteins (beans and tofu) could result in nutritional imbalance. Therefore, it is necessary to offer food based on the standard menu plan with consideration given to their food preferences in order to maintain their health and desirable dietary habits.

This study was conducted to investigate variables related to dietary fiber intake among sixth grade children in an elementary school in Daejon city. One hundred and forty-seven children completed a questionnaire for determining their socioeconomic background and their food habits. Anthropometric measurements were taken, and a 24-hour diet recall method was used to collect three-day food intakes. The socioeconomic status of the children's families belonged to the upper middle class; 53.0% of their fathers and 25.8% of their mothers had completed college or higher degrees. 27.9% of the mothers had jobs, including part-time jobs. Approximately 30% of the children skipped breakfast, 66.4% of the children preferred animal foods to plant foods, and 52.4% of the children preferred green vegetables to yellow or pale vegetables. Grilled meat dishes, such as Grilled beef rib with seasoning, Bulgogi, grilled pork belly and beef steaks, were the most popular types of food eaten outside home by the children. Daily dietary fiber intake was 14.5 g in boys and 14.5 g in girls, and these intakes are low compared to the standard guidelines. The average intakes of energy and protein of the children were 84.5% and 114.0% of the Korean Recommended Dietary Allowances (RDAs), respectively. Besides energy, riboflavin, iron and calcium intakes were below the RDAs, and especially calcium intake was only 50% of the RDAs. On the other hand, thiamin, niacin, ascorbic acid, protein and phosphorus intakes exceeded the Korean RDAs. Family income or the children's body mass index (BMI) was not directly related to dietary fiber intakes. However, higher dietary fiber intakes tended to be related to higher intakes of green vegetables and fruits. Children with higher dietary fiber intake tended to prefer plant foods to animal foods. Energy and most nutrients, except heme iron and retinol, showed positive relationships with dietary fiber intake. Especially potassium and plant origin protein and calcium were highly correlated with dietary fiber intakes(r＞0.6). From these results, it is concluded that dietary fiber intakes of these sixth grade elementary school children were less than the standard reference and it is anticipated to decrease further in the future with increased incomes. Therefore, increased intakes of dietary fiber by elementary school children should be promoted through nutrition education, together with the development of cooking methods and recipes utilizing green vegetables and fruits.

Objective: The objective of this study was to evaluate three different degrees of white striping (WS) addressing their automatic assessment and customer acceptance. The WS classification was performed based on a computer vision system (CVS), exploring different machine learning (ML) algorithms and the most important image features. Moreover, it was verified by consumer acceptance and purchase intent. Methods: The samples for image analysis were classified by trained specialists, according to severity degrees regarding visual and firmness aspects. Samples were obtained with a digital camera, and 25 features were extracted from these images. ML algorithms were applied aiming to induce a model capable of classifying the samples into three severity degrees. In addition, two sensory analyses were performed: 75 samples properly grilled were used for the first sensory test, and 9 photos for the second. All tests were performed using a 10-cm hybrid hedonic scale (acceptance test) and a 5-point scale (purchase intention). Results: The information gain metric ranked 13 attributes. However, just one type of image feature was not enough to describe the phenomenon. The classification models support vector machine, fuzzy-W, and random forest showed the best results with similar general accuracy (86.4%). The worst performance was obtained by multilayer perceptron (70.9%) with the high error rate in normal (NORM) sample predictions. The sensory analysis of acceptance verified that WS myopathy negatively affects the texture of the broiler breast fillets when grilled and the appearance attribute of the raw samples, which influenced the purchase intention scores of raw samples. Conclusion: The proposed system has proved to be adequate (fast and accurate) for the classification of WS samples. The sensory analysis of acceptance showed that WS myopathy negatively affects the tenderness of the broiler breast fillets when grilled, while the appearance attribute of the raw samples eventually influenced purchase intentions.

This study intends to provide preliminary data for improving dining experience in the restaurants of Bamboo food village and help draw up guidelines for the improvement of these dining venues by surveying customer perception and satisfaction in 15-restaurants of the food village. The restaurants were surveyed mainly for satisfaction of the menu, especially, on the signature dishes of Damyang, "ddeokgalbi" (grilled short rib balls) and "daetongbab"-the grilled short rib balls and bamboo rice. The two dishes were more liked by people in the the 20- to 29-year age group with a score of 3.92 and 4.11, respectively. Although the 30-49 age group showed the highest satisfaction score on the fixed price menu, there was no statistically significant difference. The age group of 20-29 also showed the highest satisfaction on plating and table setting with a score of 4.09 and 4.04, respectively, and there was significant difference among age groups in this regard (p<0.05). All the age groups surveyed answered "time-honored taste" should be captured when working on menus, which suggests it should be the first choice for the restaurants in the food village when they develop their menus. When it comes to the restaurant environment, satisfaction on sanitary conditions was significantly different among the groups with a score of 4.21 given by 30-49 age group and 3.88 by the 50 and over group (p<0.05). In the category of service satisfaction, the two aforementioned age groups again showed significant difference in catering to customer needs with a score of 3.99 and 3.63, respectively (p<0.05), whereas welcoming customers and serving food was scored without statistical difference by age. Being asked what needs to be done to strengthen competitive advantage of the restaurants, all the age groups answered "taste" would matter the most while the 20 to 29 and 30 to 49 age groups picked "hygiene" and the 50 and over selected "table setting and ambience" next, which was statistically different with a p value of <0.05. Regarding the competitive advantage of the Korean restaurants in Damyang Bamboo food village, the first two younger groups (20 to 29 and 30 to 49) chose "table setting and ambience" and the eldest (50 and over) age group answered "location wise advantage," indicating significant difference by age. More than 80 percent of the people surveyed were willing to revisit the venues, which suggests improving restaurant environment in Bamboo food village and offering customers a better experience are very likely to build a image of culinary tourism for Damyang.

A survey on meal preference from 287 middle school students was conducted with objective to enhance the quality of the school food service. In case of preference about cookery methods, snacks(15%) and fried food(15%) were ranked the highest while vegetable food showed the lowest. The component ratios of food items were 60.5% of vegetable food and 39.5% of meat food. The most preferred foods were 'Samkeybsal(49%)', 'pizza(41%)', 'spaghetti(33%)', 'pork cullet(31%)', and 'fried chicken (30%)'. In boiled rice, 'fried rice' and 'Bibimbab' were preferred most. The best choice of noodle was spaghetti. The highest ranked soup and stews were 'mandu and soup' and 'Kimchi stew'. Also, 'Galbijjim' and 'Sam-keybsal' showed high preference. In vegetable food, Kimchi was the lowest preference. In 'snacks', the highest preference was 'pizza'. The female students were more in favor of food items than males were except 'grilled foods' and 'steamed foods'. Above all, it is needed to do surveys about food preference periodically and active nutrition education for establishing proper eating habits for middle school students.
