The objective of this study was to compare tastes-related components and eating quality properties between Hanwoo steer and cow meats. Longissimus thoracis (LT) muscles with same quality grade (1+ grade) collected from left sides of the steer and cow carcasses were used for analyses of technological quality traits, free amino acids (FAAs), metabolites, nucleotides, fatty acids and sensory attributes. there were no differences occurring in the chemical composition (fat, protein, moisture and collagen) and technological quality traits (cooking loss, water holding capacity, shear force and color) between the two beef types (p>0.05). The cow meat exhibited significantly higher amounts of some FAAs associated with umami (e.g., glutamic acid and lysine), sweetness (e.g., proline and glutamic acid) and saltiness (e.g., histidine and glutamic acid) compared to the steer meat (p<0.05). Regarding the nucleotides, no differences occurred in all the identified nucleotides between the two beef types (p>0.05). A total of 27 metabolites were identified, however, only some compounds (e.g., acetate, creatine, creatinine, glucose and inosine, etc.) showed their significantly higher amounts in the cow meat compared with those in the steer meat (p<0.05). In terms of sensory aspects, the panelists found no differences in scores of all the eating quality traits between the two sex types of beef (p>0.05). Overall, excepts some variations in tastes-active compounds, there were no differences in the quality characteristics in general and eating quality in particular between the cow and steer meats when they were in the same quality grade.
Compliance with food group and nutrient recommendations, and self-efficacy, stage of change, perceived barriers and benefits for healthy eating were assessed among a convenience sample of college students majoring in health-related disciplines. Dietary and psychosocial data were collected using three-day food records and scales, respectively. Means (SD), frequencies, and percents were calculated on all data, and logistic regressions were used to determine whether any of the psychosocial correlates predicted the stage of change for healthy eating. Noncompliance with food group recommendations ranged from 53% for the meat/meat alternates group to 93% for the vegetables/juice group, whereas noncompliance with nutrient recommendations ranged from 26% for cholesterol to 99% for potassium. A majority of students (57%) self-classified in the preaction and 40% in the action stages of change for eating healthy. The students' self-efficacy to eat healthy was highest in positive/social situations and lowest when experiencing emotional upset. The most important perceived barrier to healthy eating was that friends/roommates do not like to eat healthy foods, and the most important perceived benefit was that eating healthy foods provides the body with adequate nutrients. The difficult/inconvenient self-efficacy subscale predicted the stage of change for healthy eating. These students would benefit from interactive learning opportunities that teach how to purchase and prepare more whole grain foods, fruits, and vegetables, enhance their self-efficacy for making healthy food choices when experiencing negative emotions, and overcome perceived barriers to healthy eating.
Objective: Although the slaughter of cull sows (CS) for human consumption and meat products processing appears quite common throughout the world, relatively limited scientific information regarding the meat quality parameters of this pork type is available. The present study aimed at providing the technological quality characteristics and eating quality of CS meat, and comparing with those of commercial pork. Methods: Longissimus thoracis et lumborum muscle samples of CS and finisher pigs (FP) at 24 h postmortem were collected and used for investigation of the meat quality traits (pH, color, shear force, cooking loss, water holding capacity), fatty acids, flavor compounds and sensory characteristics. Results: The CS meat had significantly higher moisture content (p = 0.0312) and water holding capacity (p = 0.0213) together with lower cooking loss (p = 0.0366) compared to the FP meat. The CS meat also exhibited higher (p = 0.0409) contents of unsaturated fatty acids, especially polyunsaturated fatty acids (PUFA, p = 0.0213) and more desirable PUFA/total saturated fatty acids ratio (p = 0.0438) compared to the FP meat. A total of 56 flavor compounds were identified, amongst the amount of 16 compounds differed significantly between the two pork groups. Most of the PUFA-derived flavor compounds (e.g., hexanal, benzaldehyde, and hydrocarbons) showed higher amounts in the CS meat. While, 3-(methylthio)-propanal and 4-methylthiazole associated with pleasant aromas (meaty and roast odor notes) were only found in the FP meat. Furthermore, no differences were reported by panelists for flavor, juiciness, tenderness, and acceptability scores between the two pork groups studied. Conclusion: The sow meat exhibited better technological quality and its eating quality could be comparable to the commercial pork. This study provides meat processors and traders with valuably scientific information which may help to improve the utilization and consumption level of sow meat.
Lamb has long been considered a traditional meal within Australia; however as consumer preferences have changed since the 1950's, consumption of lamb has decreased from the 1980's. This is the result of changing societal roles, particularly for females, decreasing household sizes and increasing awareness of the impact of food choices on human health. Since the 1980's improvement of farm practices and increases in genetic gains has addressed part of this decline by increasing the amount of lean meat and decreasing fat in lamb retail cuts. Yet, this has created a challenge for the industry to utilise the larger carcases now being produced. Thus, a whole value chain approach to increasing consumption has been undertaken through several research programs to create cuts which suit the modern consumer, examine nutritional and eating quality and increase adoption of value added cuts. Therefore, this paper outlines this history of changing consumer patterns and the consequent research to address these changes.
The purpose of this study was to find out the influence of Entrance Examinees' Eating Behavior on their health condition. The examinees for Chungbuk National university in 1992 were asked to fill out the questionnaire(The total number was 1054 ; 537 males, 517 females). The statistics used for data analysis were frequency, percentage, Crosstabs, Chi-square, t-test, one-way Anova, and Multiple Regression using SPSS/PC+ Program. The results are as follows. 1. Health condition due to an eating attitude: 1) As to health condition due to the food intake freguency, those who intaked fish or meat 3-5 days a week had the best heal th condition, but those who hardly intaked fish and meat or intaked them almost everyday had rather poor health condition. Those who intaked fried foods 1-2 days a week had the best health condition. The higher the freguency intaking such food or instant food was, the worse health condition was. 2) In view of health condition according to an eating attitude, it led to very good health condition to have breakfast & supper, to eat regularly, to select the nutritious foods, and to have a balanced diet. Overeating before sleeping and no meal or overeating before exam made their health very bad. Alcohol drinking & cigarrette smoking as favorite foods appeared significantly high in the boys. The more frequently they drinked alcohol and smoked cigarrette the worse their health condition was. Those who enjoyed milk, soya milk, and korean tea as favorite beverages had the better health condition than those who enjoyed coffee and soft drinks. 2. Influence of Eating Behavior on Health Condition. 1) The food intake freguency and the eating attitude influenced each other. The higher the score of food intake frequency was, the better the eating attitude appeared. 2) As a result of this study for eating behavior influencing on their health condition, the eating attitude influenced health condition, and the higher the eating attitude score was, the better heal th condition could be.
This study was aimed at examine eating behavior and food preferences of children in preschool nursery facilities. A survey was conducted on parents using questionnaires including general characteristics, eating behavior, and food habits at home and food preferences of children in 6 nursery facilities. The children involved in this study were 150 boys and 154 girls, aged 1 to 7 years old. Sixty three percent(187 children) of the children were on 'regular' meal times, and 37.0%(110 children) were on 'irregular' meal times. The major reason for their irregular meal times were 'their' concentration on other tasks'(26.6%) and 'no appetite'(25.5%). The meal eaten best by children was 'dinner' while that eaten worst was 'breakfast'. The major type of their eating habit problem was 'unbalanced diet'(62.1%), and their mothers' response to the unbalanced diet was 'trying to persuade the child'(71.6%). The number of snacks at home was one or twice a day(97.3%), and 'preference'(67.8%) was the main reason for selecting particular snacks. Their preferred staple foods were 'cooked rice with meat & vegetables and Chinese noodles', and 'noodles with bean sauce', and their preferred soup was 'seaweed soup' Also, their most preferred meat dishes were 'fried chicken' and 'thin sliced barbecued beef. Children preferred side dishes with animal foods to those with vegetable foods. Since children liked mixed dishes, it seems desirable to introduce foods which children dislike as ingredients in mixed dishes.

The purpose of this study was to investigate improvement of food habits and eating behavior in children with obesity and precocious puberty by nutritional education monitoring. The results are as follows. Average height and weight of subjects exceeded Korean height and weight standards for children as outlined by The Korea Pediatric Society. Using nutrition education monitoring, meals became more regular, overeating significantly decreased, and eating speed decreased. Further, frequencies of eating-out and night-eating significantly decreased. The most preferred menu item when eating-out was Korean food, and the most preferred menu item for night-eating was fruits, fast food, & processed food. Meat & fish and vegetable intakes all significantly increased. Fruit and milk intakes also significantly increased while bread, snack, and ice cream intakes decreased. Further, fast food & instant food intakes decreased. However, water intake was not significantly affected. The favorite food of children was meat & fish, followed by fast food & processed food. This study may provide information on dietary behavior of children with obesity and precocious puberty and suggests that nutrition education or counseling can improve food habits and eating behavior.
Objectives: This systematic review of cohort studies aimed to identify any association between specific dietary patterns and risk of colorectal cancer (CRC). Dietary patterns involve complex interactions of food and nutrients summarizing the total diet or key aspects of the diet for a population under study. Methods and materials: This review involves 6 cohort studies of dietary patterns and their association with colorectal cancer. An exploratory or a posteriori approach and a hypothesis-oriented or a priori approach were employed to identify dietary patterns. Results: The dietary pattern identified to be protective against CRC was healthy, prudent, fruits and vegetables, fat reduced/diet foods, vegetables/fish/poultry, fruit/wholegrain/dairy, healthy eating index 2005, alternate healthy eating index, Mediterranean score and recommended food score. An elevated risk of CRC was associated with Western diet, pork processed meat, potatoes, traditional meat eating, and refined grain pattern. Conclusion: The Western dietary pattern which mainly consists of red and processed meat and refined grains is associated with an elevated risk of development of CRC. Protective factors against CRC include a healthy or prudent diet, consisting of vegetables, fruits, fish and poultry.
Before Jin (秦) period, Oriental (Eastern) culture was established in Korea different from China. Bulgogi (babecued beef, 貊炙) and legume fermented soy were transmitted into China. Afterward, alcohol drink, rice cake and cookie, shic-hae (lactic acid fermented fish products), Kimchi (fermented vegetable) were introduced and modified for Korea. Buddhism was transmitted to Korea through China, but selective animal was used as food. Later period of Koryo Dynasty, meat-eating become common due to mongorian influence and distilled spirits was introduced by mongorian. During Chosun Dynasty, table setting of spoon and chopstick was established, due to Confucian influence, dog eating, raw fish and raw meat eating became popular and nutrition for elderly was developed, whereas tea culture declined. In recent period (under the Japanese rule) Chinese introduced chinese noodle, chinese cuisine, chinese pancake and sun-dried salt. many chinese cultivated chinese vegetables.

Objective: The objective of the study was to determine the effects of feeding fermented cassava leaf meal (FCLM) on growth performance, carcass characteristics and meat sensory evaluation of broiler chickens. Methods: A total of 160 Cobb-500 chickens were used during the phases of growing (21 days of age; initial weight 0.39±0.025 kg/bird) and finishing (35 days of age; initial weight 1.023±0.164 kg/bird). The whole experiment lasted for four weeks. The FCLM was included in starter and finishing diets at 0, 50, 100, and 150 g/kg inclusion levels. Total feed intake (TFI), weight gain (WG), feed conversion ratio, and nutrient digestibility were recorded. Sensory evaluation of breast meat was used to determine the eating quality of the meat prepared using roasting and boiling methods. Results: The TFI and WG decreased (p<0.05) with increasing inclusion levels of FCLM in the diets of growing chickens. Crude protein digestibility for chickens fed 0 and 50 g/kg FCLM was higher (p<0.05) than for chickens subjected to a diet with 150 g/kg FCLM. During the finishing phase, TFI increased linearly (p<0.05) with increasing inclusion level of FCLM in chicken diets, while WG decreased (p<0.05) with inclusion level of FCLM. Treatment diets had no effect (p>0.05) on the eating qualities of breast meat. However, juiciness was significant (p<0.05) for the cooking method and treatment interaction. At 50 g/kg inclusion level, boiled meat had a higher (p<0.05) juiciness score than roasted meat. Tenderness, on the other hand, was significant (p<0.05) for the interaction of gender and treatment. Females considered the boiled meat to be more tender than the males at 150 g/kg inclusion level. Using principal component analysis, a positive correlation was observed between teeth adhesion and fibrousness, flavour and juiciness, and springiness and tenderness. Conclusion: From the study, it can be concluded that FCLM can be used as an ingredient in the diets of broiler chickens. Inclusion level of 50 g/kg can be used in chicken diets during the growing phase, whereas in the finishing phase, inclusion level of 150 g/kg FCLM can be used. The FCLM did not affect the eating quality of breast meat.
