Physico-Chemical Properties for Sirloin Domestic Fed Imported Beef Cattles

국내에서 비육한 수입 생우 채끝육의 이화학적 특성에 관한 연구

Abstract

A total of 40 domestic-fed imported beef cattle were used to determine meat quality traits. Sirloin was taken from each 10 of Hereford, Angus, Hurray Grey(MG), Cross breed(Hereford$\times$Angus) and objective and subjective meat quality were assessed after a 7 days ageing(0$\pm$1$\^{C}$). Results showed that ultimate pH and fat hardness was not affected by breeds. MG showed a higher water holding capacity and consequently a lower cooking loss(%) than the other breeds(p<0.05). Angus sirloin was shown to be the toughest meat(assessed by WB-shear force), Hereford and MG resulted in the most tender meat(p<0.05). Objective meat color and sensory properties did not differ between the breeds. The current study indicated that the breeds had a similar characteristics in meat quality. However, further research on consumer preference including Hanwoo needs to be undertaken.

수입생우인 Hereford, Angus, Murray Grey, Cross breed (Hereford$\times$Angus)의 채끝을 채취하여 도축 후 0$\pm$1$^{\circ}C$에서 7일간 숙성 후 이화학적 특성을 비교하였다. 수입우 품종별 일반성분 분석결과 수분은 교잡종이 71.8%로 가장 높았으며, Hurray Grey종이 69.1%로 가장 낮았다 (p<0.05). 단백질과 지방은 품종간 유의적인 차이를 보이지 않았으나, 회분은 Hurray Grey종이 가장 높았고, Angus종이 가장 낮았다(p<0.05). 물리적 특성 중 pH와 지방경도는 품종간 유의적인 차이를 보이지 않았으나(p>0.05), 보수성은 Hurray Grey종이 가장 높았고, 전단력은 Angus종이 가장 높았으며, Hereford와 Murray Grey종이 가장 낮았다(p<0.05). 가열감량은 Murray Grey종이 가장 낮았으며, 나머지 품종들 간에는 유의적인 차이가 없었다(p>0.05). 수입우의 육색 및 관능검사 결과는 품종간에 유의적인 차이를 보이지 않았다 (p>0.05). 본 연구결과 수입우 품종간 일부 조사항목을 제외하고는 육질에 큰 차이를 보이지 않았다. 따라서 국내 수입 생우의 국내비육 후 소비자의 선호도 등, 보다 폭 넓은 연구가 필요하며, 아울러 한우와 동일한 사육프로그램에 의해 사육하여 한우와 수입 생우간 육량 및 육질에 대하여 포괄적인 비교연구가 필요하다 하겠다.
