  • This paper aims to compare and evaluate the quality of beef jerky made with Korean beef meat, Korean beef cattle and imported beef meat from Australia and New Zealand through sensory evaluation, measurement of hardness, thickness and contents of the moisture and crude lipid, and microscopic texture observation (SEM). According to the sensory evaluation, beef jerky made with Korean beef meat recorded the highest score in overall acceptability; New Zealand beef meat, the lowest. The preference of beef jerky made with Korean beef meat was shown in the appearance, smell, and texture, and especially in the taste. Whereas Korean beef jerky scored highest in color, glaze and palatability, New Zealand beef meat showed the lowest score. Korean beef meat showed the lowest in hardness, but New Zealand beef meat showed the highest as shown in the result of technical evaluation through rheometer. The evaluation through colormeter concluded that New Zealand beef meat had the highest scores in L and a values, but that Korean beef meat showed the lowest score. When it comes to the color difference compared with Korean beef meat, New Zealand beef meat showed the biggest difference. Although the moisture contents of jerky made with different beef meat showed little difference, the content of the crude lipid of jerky made with Korean beef meat and Australian beef meat was lower than that of Korean beef cattle and New Zealand beef meat. When the beef jerky is dry, fat contained in the beef meat is dissolved, which causes the glaze on the outside. Scanning electron micrographs showed that Korean and Australian beef jerky had larger gaps than Korean beef cattle and New Zealand beef jerky. It was concluded that this affected the hardness of beef jerky.

  • The purpose of this study was to compare and evaluate the quality of beef jerky made with Korean beef meat, Korean beef cattle and imported beef meat from Austria and New Zealand. The beef jerky qualities were evaluated by sensory evaluation, measurement of crude lipid, fatty acid composition of lipid, and acid value and peroxide value, and of surface observation with a microscope. According to the preference test, whereas beef jerky made with Korean beef meat showed the highest score in color, glaze, palatability, and softness, while that of made with New Zealand beef meat did received the lowest score. The crude lipid content of jerky made with Korean and Austrian beef meat was higher than that of made with Korean cattle and New Zealand beef meat. Surface of jerky made with Korean and Austrian beef meat was gappier than that of made with Korean cattle and New Zealand beef meat, and the. The acid value of jerky made with Korean and Austrian beef meat was lower than that of made with Korean cattle and New Zealand beef meat. The peroxide value of jerky made with Korean cattle meat showed higher peroxide values from the initial storage time. However, the peroxide value whereas that of jerky made with Austrian beef meat was the lowest at initial storage time, it increased remarkably with storage time and showed the highest value after the 15th day of storage. We found that the change in quality of jerky made with Korean and Austrian beef meat was less than that those made of Korean cattle and New zealand beef meat. And it could be suggested that Korean cattle and New Zealand beef meat are not suitable in making jerky.

  • This study was conducted to investigate the effects of the tenderness for the vacuum chilled, the air-frozen or the rechilled Holstein beef loin. The vacuum packaged beef was stored at 1$^{\circ}C$ and the air-packaged beef was stored at -20$^{\circ}C$ for 60 days. The rechilled beef was restored for 3 days at 1$^{\circ}C$ by using the vacuum chilled or the air-frozen beef. Hardness and chewiness of the vacuum chilled beef were better than those of the air-frozen beef. Hardness and chewiness were improved significantly(p<0.05) after the 40 days storage for the vacuum chilled beef, but there was no significant improvement for the air-frozen beef during the 60 days storage. By the rechilling process, tenderness and myofibrillar fragmentation index of the vacuum chilled and air-frozen beef improved. Especially those were improved significantly(p<0.05) in the vacuum chilled beef after the 20 days storage, and in the air-frozen beef after the 40 and 60 days storage.

  • Consumer's concerns over beef safety are increasing according to resuming U.S. beef import. And a few beef producers have converted into organic beef recently. This organic beef must have taste, nutrition and safety that consumers demand for. Korean organic beef should be gone on sale at the shop under direct management of producer's organizations or the special shop for Environmentally friendly products. So they should win consumers' confidence for beef safety and transparency in producing and marketing process.

  • The beef industry is an important part of livestock and meat production in China. China ranks third in the world for beef production. With the rapid development of the Chinese economy, beef consumption has grown rapidly, and beef consumption has been increasing with rising per capita gross domestic production. However, the domestic beef industry in China has not been able to keep pace with growth in consumption, making China a net importer of beef from other countries. Moreover, the volume of production has increased little despite rising demand. The slowing of growth in beef production in recent years has led to a sharp rise in beef prices. Domestic beef production and consumption is restricted by a shortage of beef cattle inventory. The Chinese beef industry is facing many technical problems including transformation of traditional practices, feeding and management systems, and genetic improvement of cattle breeds. The long-term, sustainable development of the Chinese beef industry is an important issue for China.

  • Objective: The objective of this research was to evaluate the physico-chemical, microbiological and sensorial qualities of restructured steaks processed from beef trimmings (grade I and II) and frozen beef (fresh beef as control and frozen beef). Methods: Beef trimmings from commercial butcher were collected, designated into 4 treatments differing in beef trimmings grade and freezing, processed into restructured steaks with 1% microbial transglutaminase and then analyzed for product quality. Results: The results showed that all meat from different groups could be tightly bound together via cross-linking of myosin heavy chain and actin as observed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Microbial counts of psychrotrophic and mesophilic bacteria were not affected by treatments (p>0.05), and no detectable of thermophilic bacteria were found. Regarding effect of beef trimmings grade, steaks made from beef trimmings grade II (16.03% fat) showed some superior sensorial qualities including higher tenderness score (p<0.05) and tendency for higher scores of juiciness and overall acceptability (p<0.07) than those made from beef trimmings grade I (2.15% fat). Moreover, a hardness value from texture profile analysis was lower in steaks processed from beef trimmings grade II than those made from grade I (p<0.05). Although some inferior qualities in terms of cooking loss and discoloration after cooking were higher in steaks made from beef trimmings grade II than those made from beef trimmings grade I (p<0.05), these differences did not affect the sensory evaluation. Frozen beef improved the soft texture and resulted in effective meat binding as considered by higher cohesiveness and springiness of the raw restructured product as compared to fresh beef (p<0.05). Conclusion: The results indicated the most suitable raw beef for producing restructured steaks without detrimental effect on product quality was beef trimmings grade II containing up to 17% fat which positively affected the sensory quality and that frozen beef trimmings increased tenderness and meat binding of restructured beef steaks.

  • The purpose of this study was to compare the usage of beef and foodservice managers' perceptions of beef quality by foodservice type. A survey was conducted on 546 dietitians, and 499 acceptable responses were used for data analysis. By weight, pork was the most used meat in foodservice institutions, followed by poultry and beef. More than half of the foodservices selected meat suppliers by competitive bidding. Approximately 85.8% of the respondents used Hanwoo beef, followed by Australian beef and Youku beef. Beef type differed significantly by foodservice type (P<0.001): most of the schools and social welfare facilities used Hanwoo beef, whereas most hospitals and business/industry operations used Australian beef. When purchasing beef, safety of beef was rated the most important, while eco-friendliness was rated the least important. Most of the dietitians understood that marbling is one of the determinants of the beef quality, but were not aware of other components. Dietitians that selected Hanwoo and Youku beef were more satisfied with quality, taste, nutrition, freshness, country of origin, package, customer, preference, and availability for various menus than those who used imported beef. Dietitians who used Hanwoo beef were the most satisfied with country of origin, whereas the others were the most satisfied with safety. Since the dietitians are in charge of planning menus and selecting meat suppliers at foodservice institutions, they should make knowledgeable decisions by understanding meat supply systems and quality of beef.
