  • Objective: It is well recognized that beef cuts from a low quality grade are usually associated with tougher, drier and less flavorful. Thus, the present study aimed at investigating the combined effects of postmortem ageing and sous vide (SV) cooking followed by oven roasting or blowtorching on the eating quality of low quality grade Hanwoo beef striploins. Methods: Hanwoo beef striploins (quality grade 3) obtained from 36 month-old Hanwoo steers were used, and the samples were chiller aged for 0 and 14 d at 4℃. After ageing, the samples were prepared into 2.5-cm steaks which were then SV cooked at 55℃ for 5 h and then raised to 60℃ for 1 h, and thereafter the SV-cooked the steaks were further roasted in oven for 20 min (SV+OV) or blowtorched (SV+TC) for 2 min. The cooked samples were analyzed for microbiological quality, browning index, Wanrner-Bratzler shear force (WBSF), aroma flavor compounds and sensory properties. Results: The SV cooking significantly reduced the WBSF values in beef samples (p<0.05). Blowtorching after SV cooking led to a browner surface of the beef steaks (p<0.05). The samples treated with SV+OV or SV+TC exhibited higher levels of Maillard reaction-derived aroma flavor compounds such as; pyrazines and sulfur-containing compounds compared to those just SV cooked. More especially, the SV+OV- or SV+TC- treated samples presented significantly higher flavor and overall acceptability scores compared to those just SV cooked (p<0.05). Ageing beef for 14 d significantly improved the tenderness by reducing the WBSF and increasing the tenderness scores. Conclusion: Thus, the combination of postmortem ageing and SV cooking followed by additional treatments (blowtorching or oven roasting) could be used to improve the eating quality especially tenderness and flavor as well as overall acceptability of low grade Hanwoo beef.

  • The purpose of this study was to investigate several aspects of eating out behaviors among older persons. In aging society, need of seniors are getting higher than before, they want to have a good quality of life. Specially it is changed in family structure and life style. The food habits of older person will be getting change. Hence this study tried to show the various thought of eating out behaviors, interested factors to select restaurants and menus, tendency to do eating out, inconveniences to use of eating out so on. The questionnaires were completed by 150 older persons living over 60 years old in Busan. They were mostly health and active. The most study were focused young generation however the old generation was not interest in eating out behaviors. Therefor this study gave a lot of approach to develop food habits for old person. The result were as followed: The attitude of eating out were positive, once or two times in a week was highest response 138(92%). As frequently selected food were vegetable and Korean food restaurants. Moreover older person expect a meaningful food culture among older person. As a bad grade of eating out were not to be kind to seniors, never concern to characteristic older. They wanted to have a food for their health and to share with their spare time. The study of eating out style will be very important issue of silver industry. To develop menus and to make older person culture is very needed in aging society.

  • Purpose: The European Organization for Research and Treatment of Cancer quality-of-life questionnaire-OG25 was developed to evaluate the quality of life in patients with stomach and esophageal cancer. The following are included in the OG25 but not in the STO22: odynophagia, choked when swallowing, weight loss, trouble eating with others, trouble swallowing saliva, trouble talking, and trouble with coughing. In this study, we evaluated the quality of life of gastrectomized patients using both, the OG25 and the STO22. Materials and Methods: A total of 138 patients with partial gastrectomy (PG) (distal gastrectomy=91; pylorus-preserving gastrectomy=47) and 44 patients with total gastrectomy (TG) were prospectively evaluated. Body weight and scores from the OG25 and STO22 were evaluated preoperatively and at 3 weeks, 3 months, and 6 months after surgery. Results: Patients with TG had significant weight loss compared to patients with PG. At 3 months, TG was associated with worse scores for dysphagia, eating, odynophagia, trouble eating with others, trouble with taste, and weight loss on the OG25. TG was also associated with dysphagia, eating restrictions, and anxiety on the STO22. The OG25 helped differentiate between the groups with respect to weight loss, odynophagia, choked when swallowing, and trouble eating with others. The OG25 scores changed over time and were significantly different. Conclusions: The OG25 is a more sensitive and useful scale than the STO22 for evaluating the quality of life of gastrectomized patients, especially those with total gastrectomy.

  • Despite several issues in relation to human health, beef is still a most popular meat product among large section of society due to the presence of high quality protein and other nutrients. The current paper reviews numerous studies that provide nutritional profiles and health implications of high marbled beef consumption. In relation to lipid content of beef, intramuscular fat contains high level of PUFA and MUFA compared to other beef fat. Level and composition of intramuscular fat varies depending on breed and feeding regime. Literature suggests that the marbling is more complex than the development of subcutaneous fat and marbling not only provides good fatty acids but also contributes to the higher eating quality of beef. Finally, the current work emphasize that meat plays a pivotal role in nutritious diets, high quality marbled beef is not only of excellent eating quality but also contain more beneficial fatty acids.

  • Objectives : The aim of this study was to assess whether individuals who visit clinics to ask medical help for obesity treatment depict comparable levels of depression, body dissatisfaction, eating psychopathology and lower quality of life. Methods : This is a cross sectional study with 534 females who sought treatment for their obesity or overweight being recruited in seven clinical units in Seoul, Korea. The patients group was divided into two groups. The group 1 consisted of the patients with BMI >$25\;kg/m^2$. The women who showed BMI ${\leq}\;25\;kg/m^2$ among patients recruited for this study were classified as the group 2. The control group (group 3) was composed of 398 healthy females who have never tried to lose weight. Results : We found that group 1 had higher frequency of more than moderate level of depression than group 2 and group3 did. Both patients groups showed greater eating disordered attitudes and behaviors regardless of obese condition than the control group. Group1 showed relatively lower level of quality of life than group2 and group3 in terms of the quality of life related to physical well-being. In addition, the control group reported higher quality of life in psychological health than both patients groups did. Conclusions : In conclusion, it is necessary for clinicians to make a careful evaluation of depressive tendency and eating disorders when obese women seek for medical help. The combination of medical treatment and psychological approach for obese women would result in higher quality of life.

  • Concerns about meat quality, including chicken meat, for the human diet has led to many attempts to manipulate the carcass fat and increase the eating quality. For actual eating quality, the birds must be grown and finished in a manner that results in meat that are tender, succulent and of good flavor, as well as being free from any foreign taint, flavor or safety hazard. Tenderization treatment with high voltage(820V) electrical stimulation and prechill muscle tensioning would improve the tenderness of chicken meat. Proper programs for the withdrawal of feed and water require a team approach for maximizing yield of meat and minimizing carcass contamination. Also effding of supplemental levels of-tocopherol to poultry with vegetable or fish oils increases of desirable polyunsaturated fatty acid(PUFA) content and stablizes the meat against rancidity and fish off-flavors. The nutritional effects of varying dietary ingredients on broiler carcass fat content are also important. Increasing the levels of energy in the ration increases the carcass fat content, while increasing the proteing levels decreases carcass fat content. Supplement-tation of poultry diets with amino acids such as methionine, lysine, glycine and tryptophan as well as amino acid such as well as amino acid mixtures can reduce body fat deposition. Normal stress leads to chicken muscular damage resulting in reduced meat quality, but this can be controlled by preslaughter management practices. Feed manufactures can utilize ntilize nutrient modulation to control pale soft exudative(PSE)syndrome. Finally, the success in poultry meat production depends on the consistent achievement of carefully selected levels of quality. Quality assurance should be the wider function of incorporating quality into the production system and the combination of motivating quality into actions and operations.

  • This study was conducted to identify the relationship between sleep quality, stress, depression, and eating attitudes of shift work nurses, and to determine the influencing factors of eating attitudes. Participants were 152 shift work nurses working at a university hospital and data collection was performed from July 1 to July 20, 2021. The collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. In this study, the prevalence of abnormal eating attitudes at clinical and sub-clinical levels was 7.9% and 19.1%, respectively. There was a positive correlation between eating attitudes and depression, and the influencing factors of eating attitudes were alcohol drinking(1 time/month) and depression. Therefore, it is necessary to find strategies to prevent depression in order to improve the eating attitude of nurses working in shifts, and repeated research on the relevance of alcohol drinking and eating attitudes is needed.

  • The purpose of this study was to identify the behavioral, attitudinal, and demographic correlates of light, medium, and heavy users of eating out at family restaurants. Among 358 reponses from the subjects, 224 responses were utilized for the analysis, and 134 responses were reserved for validating the discriminant function. Descriptive statistics, reliability analysis, stepwise discriminant analysis, canonical discriminant analysis, and anova analysis were used for this study. The findings from this study were as follows: First, He behavioral characteristics were found to discriminate among the three usage groups. Second, it was found that heavy users expressed greater difference between perception and expectation on the quantity of food that are appropriately served and the consistent quality of food at every visit. Third, the usage rate of eating out was not dependent on the sex, but dependent on the companion, average expenditure, and the time of eating out in chi-square test. Finally, the results of the study provide some insight into the pattern of marketing strategies that can be successfully used by the managers of family restaurants.

  • Background: The objectives of this study were to investigate the effects of persimmon peel (PPM) supplementation on carcass performance, pork quality, eating quality, fatty acid composition, and cholesterol concentration of the porcine longissimus dorsi muscle. Results: No adverse effects of PPM supplementation were observed on carcass and meat quality characteristics among the treatment groups (P > 0.05), whereas pork loins from pigs fed a diet supplemented with 0.9 % persimmon peel (T3) showed more tender meat than did pork loins from pigs fed a control diet (P < 0.01), even though no significant difference was observed between the control and T1 group. The T3 group had higher ratio of polyunsaturated fatty acids relative to saturated fatty acids (0.33 vs. 0.28, P < 0.05) and lower total cholesterol concentration (94.4 vs. 99.1 mg/g, P < 0.05) compared to the control group. Persimmon peel appeared to have beneficial effects on fatty acid composition and cholesterol concentration, probably leading to a hypocholesterolemic effect. Conclusions: Animal diets fortified with persimmon peel represents an efficient and useful method for improving the nutritional quality of pork without impairing growth performance and eating quality properties.
