This study compared the characteristics of consomme prepared by homeskill(Consomme A) and quantity food production skill(Consomme B) as well as by the main ingredients of Consomme. The highest portion of amino acids in Consomme was arginine, followed by glutamic acid and alanine. In sensory evaluation, Consomme A prepared with chicken meat and Consomme B with mixed beef & chicken were most preferred. This result showed that higher total amino acid content gave better sensory scores. There was a significant correlation between the turbidity of sensory evaluation and the color b value. Turbidity and viscosity of instrumental measurement were also significantly correlated.

Intramuscular fat (IMF) content in skeletal muscle including the longissimus dorsi muscle (LM), also known as marbling fat, is one of the most important factors determining beef quality in several countries including Korea, Japan, Australia, and the United States. Genetics and breed, management, and nutrition affect IMF deposition. Japanese Black cattle breed has the highest IMF content in the world, and Korean cattle (also called Hanwoo) the second highest. Here, we review results of research on genetic factors (breed and sex differences and heritability) that affect IMF deposition. Cattle management factors are also important for IMF deposition. Castration of bulls increases IMF deposition in most cattle breeds. The effects of several management factors, including weaning age, castration, slaughter weight and age, and environmental conditions on IMF deposition are also reviewed. Nutritional factors, including fat metabolism, digestion and absorption of feed, glucose/starch availability, and vitamin A, D, and C levels are important for IMF deposition. Manipulating IMF deposition through developmental programming via metabolic imprinting is a recently proposed nutritional method to change potential IMF deposition during the fetal and neonatal periods in rodents and domestic animals. Application of fetal nutritional programming to increase IMF deposition of progeny in later life is reviewed. The coordination of several factors affects IMF deposition. Thus, a combination of several strategies may be needed to manipulate IMF deposition, depending on the consumer's beef preference. In particular, stage-specific feeding programs with concentrate-based diets developed by Japan and Korea are described in this article.

The purpose of this study was to investigate the adaptation and preference for South Korean food among North Korean refugees. A survey was conducted on 220 North Korean refugees regarding general questions, adaptations, and preference on consuming dishes in South Korea. The results of the survey showed that the average difficulty degree scored with the adaptation to South Korean food was 3.06 points out of 5.00 points. The adaptation to Korean food was investigated as 'average' and some North Korean refugees had some difficulties in South Korean food. Some respondents described South Korean food as having very strong flavor that tastes more sweetened, seasoned, and spicy than North Korean food. The extended residency in South Korea allowed North Korean refugees to become more familiar with sweetened flavors. Most of them enjoy an oily and spicy taste more than South Koreans. North Korean refugees like Ssal bap, Naengmyeon, Doenjang-guk, Galbi-jjim, Bulgogi(beef, pork), Chaesobokkeum, Oi-saengchae, Chaeso-jeon, Baechu-kimchi, Saengsun-twigim, Soondae, pears, fruit juice, and spring water. North Korean refugees over the age of 30 years enjoy classic foods such as Japgokbap, Gimbap, Jumeokbap, Hwedeopbap, and Chobap. On the other hand, North Korean refugees less than 30 years old enjoy new foods like ramen and spaghetti.

This research was carried out as a basic survey to provide more effective and improved food service for the soliders of the Armed Forces who are serving to defend the Republic of Korea subjects were selected randomly who were serving in the army for a short-term. Following is the result of a survey regarding the situation of their meals, dietary life, and their food preference of 190 kinds of foodstuffs. As a result of surveying the dietary life of the soldiers, they indicated that there was dissatisfaction in the current Food Service because it lacked tasted and the same kind of meals were being served too frequently with regard to this, many subjects expressed that they were eating out because of the quality of they get from the regular meal service the meals, that is they were eating in restaurants to resolve their dissatisfaction over the quality of the meals. It was also surveyed that in the current meals there is a need to diversify ways in preparing food, increase the number of dishes, and improve the tasts of the food by using improved cooking method. It seemed that the soldiers were satisfied in the quantitative level of the current food service but that there is a need to improve the meals in quality. Following is the result of a survey on the preference of foodstuffs. In case of rice as the stationary food, mixture of five-grain plain white cooked rice showed a higher propensity compared to plain whte boiled rice. This shows that soliders prefer various cereals in their rice. Soliders liked soup made from meat better than vegetable soup or soup made from fish. Especially there was a high performance for beef soup. Soliders liked One-dish meals such as fried rice or boiled rice with asserted mixtures, noodled, and dumplings on the whole-soliders generally liked vegetables and they liked uncooked vegetables better than cooked vegetables. Generally everyone liked beverages and there was a high preference for dessert. Among various rice cakes soliders liked songpyon(rice cake steamed on a layer of pine needles) and injolmi (cake made from glutinous rice). On the other hand, soliders did not like food prepared with fish, biscuits and candy very much. In the way of preparing food, soliders liked food that were fried in deep far rather than food cooked in water. Also they liked pot stem better than soup. As examined in the survey, those surveyed wanted improvement in the quality and diversity of the food rather than increase the number of food and quality. Therefore there is a need for diversified supply and demand of quality of meal service.

In this study, we tried to compare and determine wat the effects will be to the sensory characteristics and textures of a meat balls when the proportion of the textu-rized soy protein (TSP) varies from 0, 10, 20, 30, and 40％. Evaluation was conducted through sensory evaluation and objective evaluation. The results are as follows: 1. As the level of 40％ TSP increased the meat ball maintained a better appearance. 2. Color, beef flavor, tenderness, juiciness and acceptability shelved the tendency to decrease as TSP proportion increased. (1) No significant change to the outside color revealed to the level of 20％. How-ever, inside color showed a significant change after the level exceeded 20％. (2) Soy flavor tended to increased and beef flavor tended to decrease as the TSP proportion increased. However up to the level of 30％ one could not taste the flavor of soy. (3) Tenderness tended to decrease as the TSP proportion increased however difference was not significant. (4) Juiciness decreased as TSP proportion increased. (5) Acceptability tended to decrease as the TSP proportion increased but to a 40％ addition, the level of TSP did not have much effect on the sensory characteristics as long as sufficient seasonings were added. 3. Instron measurement incidated that springiness, cohesiveness and shear force tended to dcrease as the TSP proportion increased but hardness increased and chewi-ness was the highest at 20％ TSP level. 4. Color and difference meter indicated that the figure L and b tended to increase and AE decreased as the TSP proportion increased. 5. Cooking retention tended to increase as the TSP proportion increased. From thiss tudy, we can conclude that the level of up to 40％ of TSP in making meat ball did not affect the preference.

For development of food of Jong-ga (Jeonju Hakindang) and its commercialization, this study investigated physico-chemical properties and quality characteristics of Mannaji (boiled beef down in Korean soy sauce) prepared with conventional or pre-heating methods during storage period (0, 4, 8, 12, 16, and 20 weeks) at $4^{\circ}C$. As storage period passed, pH decreased in both conventional and pre-heating methods. Forchromaticity, brightness ($L^*$) significantly decreasedwhile redness ($a^*$) and yellowness ($b^*$) significantly increased during storage period. After 4 weeks of storage, hardness of Mannaji with conventional methods was higher compared to before storage. Thiobarbituric acid reactive substances (TBARS) of both conventional and pre-heating methods increased above 1.2 MDA mg/km, which is the acceptable criteria for intake. Although volatile basic nitrogen (VBN) values slightly increased in 4 weeks of storage, there were no significant differences in VBN and maintained food acceptable level until 20 weeks of storage. Sensory panelists showed preference for Mannaji with pre-heating methods compared to conventional methods.

The consumption of meat is increasing in India and agriculture is considered as the backbone of a majority of people. Livestock plays a significant role, and poultry and dairy are the major sectors contributing to economic development. The majority of meats consumed in India are fish, bovine, mutton, goat, pig, and poultry. In Indian context, culture, traditions, customs, and taboos influence meat consumption to a great extent. However, studies show that urbanization has been causing a rise in demand for meat products. India is the world's second largest exporter of beef. In India, 95% of goat meat produced is consumed locally. Meat consumption, in particular, is determined by the religions where pork is forbidden to Muslims and beef is prohibited to Hindus. The preference and consumption of chicken meat can be considered as a universal phenomenon and chicken meat is greatly accepted by consumers in India as compared to the other meat consumption. The increase of chicken meat consumption is due to the versatility of the meat, relatively low cost in comparison to other meat, and the acceptance of the chicken meat to all religions. There has been a great rise in the production of livestock products and this is expected to continue in the future. The pattern of meat consumption depends considerably on culture, tradition and urbanization. This review was formulated with the objective of identifying the meat consumption patterns in a typical Indian society.

The physicochemical and functional traits for loin muscles of Hanwoo steers were compared by quality grade (QG). A total of 500 Hanwoo steers were slaughtered, their carcasses were categorized into four groups (QG 1++, 1+, 1, and 2), and the longissimus dorsi muscles were analyzed. QG 1++ group had the highest fat and lowest moisture content (p<0.05). QG 1++ showed higher $L^*$ and $b^*$ color values, higher cooking loss, and lower shear force values, compared with the other groups (p<0.05). The flavor, tenderness, juiciness, and preference scores by sensory evaluation were highly ranked for premium QG groups (1++ and 1+). Regarding the micro compounds, QG 1 and QG 2 had greater amounts of inosine monophosphate, and QG 2 had greater amounts of anserine, carnosine, and creatine, than QG 1++ (p<0.05). QG 1++ and 1+ had higher percentages of oleic acid (C18:1) than QG 2 (p<0.05). Within premium QG 1++ and 1+, the results of the nucleotides, free amino acids, dipeptides, and fatty acids did not show any distinctive differences. Hanwoo beef as determined by the current grading system was not significantly different in terms of functional components; the only significant difference was in intramuscular fat content.

Objective: Recently, indigenous Korean grass Sasa quelpaertensis Nakai (SQ) has garnered much interest as a roughage source for livestock to mitigate its adverse effects on habitat diversity. Thus, the objective of the present study was to evaluate the ruminal fermentation, palatability, and nutrient digestibility of SQ for Korean native beef cattle (Hanwoo) using in vitro rumen fermentation, in situ rumen degradability, and in vivo feeding trials. Methods: Using in vitro tests with rumen fluid as the inoculum for 48 h, ruminal fermentation of SQ was evaluated and compared with that of other roughage sources commonly used in Korea (i.e., rice straw, Timothy hay, and Italian ryegrass [IRG]). Additionally, an in situ trial 96 h was performed using three cannulated Hanwoo steers. Further, an in vivo trial was performed using eight Hanwoo steers to compare the palatability of SQ with rice straw in total mixed ration (TMR) and forage-concentrate separate feeding conditions. Finally, an in vivo digestibility trial of SQ fed as TMR of two particle sizes was performed with four Hanwoo steers. Results: In vitro and in situ trials revealed that SQ was comparable or superior to rice straw in terms of the ruminal fermentation characteristics of pH, gas production, total volatile fatty acid content, and effective ruminal dry matter digestibility (DMD), although its fermentability was lower than that of Timothy hay and IRG. In the palatability test, steers showed a greater preference for SQ when given as TMR. The total tract DMD of SQ fed as TMR was 75.9%±1.37%, and it did not differ by particle size. Conclusion: The feed value of SQ as a roughage source for Hanwoo steers is comparable or superior to that of rice straw, particularly when provided as TMR.

This study was conducted to investigate the intake of a kind of Gom-Tang (Beef soup made with internal organs and bone), which is the Korean traditional food, and factors affecting the eating behavior of customers. Two hundred male customers of a H Korean Restaurant specialized in Gom-Tang, which is a well-known restaurant in Seoul, were surveyed from June 26 to 29, 1990. The results were shown as follows. (1) ${\ulcorner}$Frequency of intake${\lrcorner}$ and ${\ulcorner}$preference${\lrcorner}$ were very high. Those who took a kind of Gom-Tang ${\ulcorner}$more than once a week${\lrcorner}$ were 66.5% of the subjects. Those who evaluated ${\ulcorner}$good${\lrcorner}$ for the taste and flavor were 86.5% and 59.0% of the subjects, respectively. (2) The reasons why they chose a kind of Gom-Tang from among many Korean traditional foods were ${\ulcorner}$preference${\lrcorner}$ and ${\ulcorner}$phygiological condition${\lrcorner}$ in ${\ulcorner}$high frequency of intake${\lrcorner}$ group. ${\ulcorner}$Phygiological condition${\lrcorner}$ was more critical factor than ${\ulcorner}$preference${\lrcorner}$ in ${\ulcorner}$low frequency of intake${\lrcorner}$ group. (3) The effect of the intake of a kind of Gom-Tang on health was evaluated as ${\ulcorner}$healthy${\lrcorner}$ (80.5%). ${\ulcorner}$No effect${\lrcorner}$ and ${\ulcorner}$harmful${\lrcorner}$ were 30.5% and 6.5%, respectively. (4) ${\ulcorner}$High frequency of intake${\lrcorner}$ group, mainly more than 50 years of age, had a high ${\ulcorner}$preference${\lrcorner}$ and ${\ulcorner}$food knowledge${\lrcorner}$ as well as positive ${\ulcorner}$eating behavior${\lrcorner}$ and ${\ulcorner}$healthy state${\lrcorner}$, ${\ulcorner}$Middle frequency of intake${\lrcorner}$ group, mainly the forties, had a high ${\ulcorner}$preference${\lrcorner}$, but had less positive ${\ulcorner}$eating behavior${\lrcorner}$ than ${\ulcorner}$high frequency of intake${\lrcorner}$ group. ${\ulcorner}$Low frequency of intake${\lrcorner}$ group, mainly the twenties and thirties, had a medial ${\ulcorner}$preference${\lrcorner}$. They took a kind of Gom-Tang for reasons of ${\ulcorner}$on the recommendation of friends${\lrcorner}$ better than ${\ulcorner}$preference${\lrcorner}$. Foregoing results showed that ${\ulcorner}$a kind of Gom-Tang${\lrcorner}$ was a typical food recognized as ${\ulcorner}$healthy${\lrcorner}$ as well as ${\ulcorner}$delicious${\lrcorner}$. This may suggest that ${\ulcorner}$a kind of Gom-Tang${\lrcorner}$ is a candidate for the effective food on nutritional education.
