The quality characteristics of brand and non-brand Korean beefs, found in retail circulation, were studied via physicochemical and microbiological analysis and sensory tests. The average price of 100 g of brand Korean beef sirloin was 7.6 USD (1USD=950won), while the price of non-brand Korean beef was 3.1 USD. The fat content of the brand beef seemed to be higher, yet the difference was not significant. In both the brand and non-brand beefs, pH levels were approximately 5.27 We found that lightness (Hunter L value) tended to be higher in the brand beef, but again, this difference was not significant. For the cooked beef texture, the brand beef seemed to have lower gumminess, and had significantly less fracturability, than the non-brand beef. Significant differences could not be found with regards to microbiological stability between the two types of beef. In the raw beef sensory test, significant differences were identified for meat color, fat color, fat in muscle, flavor, and general preference. Also, the after cooking sensory test showed that brand beef had better characteristics for color, flavor, juiciness, softness, taste, chewiness, and preference.

Since the last decades, livestock ranching has been fast industrialized and the global trade of meat products is sheer increasing. And the Korean government opened its domestic beef market to meet increasing domestic demand for beef. In this context, domestic beef production took its way to specialization and scale economies, and subsequently the commodity chain of beef became different from the conventional one. Such institutions as beef quality grade, HACCP, and brand marketing have strong influence on current beef production systems. Furthermore, along with the macro-scale change, regional and local systems and actors also transform the beef commodity chain. Hampyong-gun, which had once been a declining rural and under-served region in the past, is now actively reviving its economy by producing industrialized, specialized, and localized beef. Such native beef production is both impacted by and associated with multi-scaled actors, their institutions and supporting discourses. These heterogeneous actors and institutions form a newer form of native beef system in the region.

The purpose of this study is to determine potential associations among consumer preference for American beef, consumers' involvement in selection of desired beef, and their intentions to purchase beef. In order to meet the above purpose, this study surveyed the visitors who shopped at 2 big discount stores selected in each of 3 metropolitan cities(Seoul, Daejeon and Daegu) from July 11 to 13, 2008. Total 278 sheets of the questionnaire were collected and used for final data analysis. As a result, it was found that the consumers responded most sensitively to the safety of food when buying beef but didn't care much about the amount of fat and beef brand. In terms of imported beef, it was found that Australian beef was considered reliable by consumers, and their preference for Korean beef was positively correlated with that for Australian beef. In addition, in regard to the attributes of beef selection, it was found that low involvement group had higher intentions to purchase American beef than high involvement group. In order to determine the potential effects of consumers' involvement in the attributes of beef selection on their intentions to purchase American beef, this study conducted data analysis in control of consumer preference for American beef. As a result, it was found that consumers' involvement in the attributes of beef selection had significant effects on their intentions to buy American beef. And sex was found to be one of the demographic characteristics associated with involvement in the attributes of beef selection, particularly associated with low involvement. Depending on sex, it was found that women had lower preference for American beef than men.

This study was performed to develop a rapid immuno-assay kit, by using a specific antigen to detect Hanwoo brand meat. We selected a synthetic antigen specific to our target antibody, named BIO-TAG (Tyr-D-Ala-Phe), by utilizing a computer-based analysis and literature review. BIO-TAG tagged with adjuvant was subcutaneously injected in sheep and Hanwoo. The serum and meat juice of the immunized or non-immunized animal were then analyzed, to measure the titer of antibody by ELISA and Western blot. The amount of antibodies against the BIO-TAG increased (p<0.05) in serum by vaccination. Furthermore, meat juice from the immunized Hanwoo showed greater (p<0.05) antibody titer, compared with those from non-immunized groups. To optimze the dilution factor, we performed dot-ELISA, with various combination levels of BIO-TAG. Results from dot-ELISA showed that 2 mg/mL BIO-TAG was sufficient to distinguish the immunized meat from non-immunized groups. These results support our hypothesis that simple immunization of Hanwoo generates a sufficient amount of antibodies to be detectable in the meat juice by means of the immune-assay. Therefore, specific Hanwoo brand meat can be more precisely identified by our rapid diagnostic kit. This technology can deter possible fraud of counterfeit meat brands in the Korean domestic market with ease and rapidity; and offers a new tool that guarantees consumers high quality Hanwoo brand beef.

This current survey was conducted to examine consumer attitudes toward factors determining beef purchasing and improving distribution systems. The frequency of beef purchasing was shown to reflect social and economic status, where inhabitants in large cities, such as Seoul, with higher salaries showed a higher frequency. In addition, consumers that were in their forties bought beef more frequently than consumers that were in their twenties. Consumers in Seoul and the megalopolis with a monthly income of higher than 200 million won preferred to purchase meat from department stores and discount markets. In contrast, people in small cities with lower incomes tended to buy meat from butcher shops and brand shops. In a question regarding unsatisfaction factors of retail beef, individuals that were in their thirties with a high income had concerns associated with packaging problems. For people under thirty with low income, the consistency of quality and price were the prime concerns. In regards to the beef grading system, consumer response varied between inhabitants, monthly income and age group, where consumers from small cities that were in their twenties and forties with a low income had a negative viewpoint. For the differential beef distribution system, housewives between the ages of 30 and 40 from a small city with an income higher than 200 million won had a positive response; however, a large number of consumers were not familiar with this system. The most demanding beef cuts were in the following order: loin, flank and rib. In addition, the most important factors determining purchasing beef were as follows: price, breed and portion.

The study was performed through questionnaire to determine purchase characteristics and consumers' satisfaction for Hanwoo beef for 400 residents in Busan, Gyeongsangnam-do, Daegu and Gyeongsangbuk-do. The results obtained from 363 consumers excluding 37 improperly answered ones were statistically analyzed. The properly answered consumers were classified according to gender, 107 (29.5%) male, 256 (70.5%) female, and ages, 70 (19.3%) twenties, 97 (26.7%) thirties, 131 (36.1%) forties, and 65 (17.9%) over fifties. Consumers having older ages purchased Hanwoo beef more frequently (p<0.05), and Hanwoo specialty shop operated by farmers cooperative was the most popular purchasing sources. Consumers' favorite retail cuts for Hanwoo beef were in the order of loin (43.5%), ribs (22.9%), tender loin (10.5%), brisket (9.9%), round, fore (4.7%), others (3.3%), chuck (2.8%), strip loin, rump (2.5%). For the experiences of purchasing imported beef, 24.55% and 22.3% of consumers answered for 'sometimes' and 'yes', respectively, for the reason of 'low price' (73.3%). Consumers answered 'sometimes' (69.1%) for the question of disguisement of imported beef to Hanwoo beef, and thought traceability (61.7%) and country of origin (17.1%) would be the most effective methods to prevent disguisement. Percentages of responses were 61.1% and 75.5% for traceability and country of origin, respectively, under the assumption of consumer's trustworthiness of above 70%. Prerequisites for Hanwoo beef to succeed as a brand were in the order of taste (3.90 points), consumers' satisfaction (3.28 points), consumers' trustworthiness (3.20 points), safety (3.03 points). Consumers' satisfaction is influenced by the age, academic background and the occupation (p<0.05). Safety is expected to show the difference by the educational background (p<0.05) and the occupation (p<0.01), whereas consumers trustworthiness is influenced by the educational background and income (p<0.05). From the results obtained in the current study, it is concluded that traceability and country of origin is essential to gain consumers' satisfaction and trustworthiness, and that the most important factors for branding Hanwoo beef would be taste and safety.

The aim of this study was to determine the relationship between sensory properties and Warner-Bratzler shear (WBS) for branded Hanwoo beef. Eight subprimal cuts purchased from the branded Hanwoo beef of 3 quality grades ($1^{++}$, $1^+$, 1) at 13 stores were determined the tenderness using WBS and evaluated the sensory properties (tenderness, flavor, juiciness, overall acceptance) by trained sensory panels. The results of sensory evaluation were analyzed by four WBS value classes (<3.46 kg, 3.46-4.09 kg, 4.09-4.72 kg, >4.72 kg). The results from the sensory evaluation (tenderness, flavor, juiciness, overall acceptance) for subprimal cuts of WBS force value less than 3.46 kg had high scores, whereas WBS force value more than 4.72 kg had low scores (p<0.05). Correlation coefficient of WBS measurements with sensory ratings was -0.67 (tenderness), -0.53 (flavor), -0.49 (juiciness), and -0.57 (overall acceptance). From these results, consumers can distinguish sensory taste of branded Hanwoo beef using WBS categories and beef industry can apply index of taste for brand Hanwoo beef by WBS categories.

This research was to investigate the operation of contracted food service management and menu preferences of middle school students in Seoul. Questionnaires were distributed between Dec. 1 and 20,2000 in 10 middle schools. Statistical data analyses were completed using the SAS package, including the mean, standard deviation and frequency analysis. The results can be summarized as follows: The average number of meals per middle school was 1,000 and only lunch was served in each school. In terms of facilities and equipment, low rates of the possession of cooking equipment and food carts were the major hindrance to work and production efficiency. The students' main demands were taste, sanitation, variety of food, the introduction of brand foods, the price of foods, and the speed of reaction to their dissatisfaction. Most of the schools provided rice for lunch, while the students preferred noodles, mandu and bread. beef-rib soup was preferred to broth. for side dishes, fish, roasted meat and fried foods were highly favored, along with processed foods, with low preferences for vegetables. The middle school students favored fruits. Lastly, they requested that the quality of school meals be improved through the development and supply of various desserts.

A total of 100 swelled, springered or flippered canned meat and fish products were studied the degree of contamination with clostridias and serological relationships to Hobbs'13 "heat resistant" types, heat resistance of spores and susceptibility of Clostridium perfringens isolates to several antibiotics. Samples examined in this study were collected from Seoul area from June to October, 1975 and prepared in Korea. Clostridias were isolated from 46(46%) of these samples; 19 strains of Cl. perfringens, 9 strains of Cl. oedematiens A, B, 5 strains of Cl. sordelli, each 3 strains of Cl. chauvoei, Cl, oedematiens C.E, and Cl. difficile, 2 strains of Cl. sporogenes. The highest percentage of contamination by Cl. perfringens was found in beef products(26.5%), and the following(5.2%) in mackerel pike and none in baitop shell. whale, manna brand. and top shell. One of 19 isolates of Clostridium perfringens found in meat products was shown to produce heat resistant spores which resist $100^{\circ}C$ for 60 minutes and others were heat labile strains which is killed at $90^{\circ}C$ for 30 minutes. The distribution of Hobbs' serotype of 19 isolates were each 4 strains of type 6, 8, and 11, 1 strain of type 13 and others untypable. 19 Strains of Cl. perfringens were shown a marked susceptibility to cefamezin, lincomycin and minocin and relatively sensitive to vibraimycin, geopen, and chloramphenicol. A marked resistance to kanamycin, colimycin, and gentamycin were shown. Aerobic enteropathogens from samples were not recovered.
