Abstract

This study was conducted to evaluate the meat quality of pork produced by feeding fermented rice bran (FRB) (10 to 20%). In the proximate composition analysis there were no significant differences, but the FRB treated groups showed a tendency for higher moisture content and a lower fat content. There were no significant changes found in the physicochemical property analysis, except for cooking loss and water holding capacity, which are the most important factors for estimating meat quality. The cooking loss of the FRB pork was significantly lower than that of the control group (p<0.01). The water holding capacity of the 20% FRB roup was higher than that of the control group (p<0.01). The shear force value of the 20% FRB group was also higher than that of the control group, but the 10% FRB group showed no difference from the control group. The total free amino acid volume of the meat increased, depending on the volume of FRB added. The contents of glutamic acid, glycine, and alanine, which are important factors for taste and flavor, were higher in the FRB groups an the control group. In the sensory analysis, the FRB groups showed high scores for color, aroma, flavor, juiciness, taste, and overall acceptability. Taken together, adding FRB to the feed improved the quality of pork.

본 연구는 발효쌀겨의 급여(10-20%)가 돈육의 품질에 미치는 영향을 알아보고자 실시되었다. 일반성분평가결과, 발효쌀겨 20% 급여구의 돈육이 급여하지 않은 대조구 돈육에 비하여 수분함량이 높고, 지방함량이 낮은 경향이었으나 유의적 차이는 없었다. 이화학적 특성결과, 가열감량은 처리구가 대조구에 비하여 유의적으로 낮았다(p<0.01). 육질평가에서 가장 중요한 항목인 보수력은 처리구가 대조구에 비하여 높게 나타났다(p<0.01). 돈육의 연도를 측정하는 전단력(shear force)은 대조구와 처리구 사이에서는 유의적인 차이가 없는 것으로 나타났으나, 지방함량이 적고 보수력이 높은 발효쌀겨 20% 급여구에서 높은 특성을 나타내었다. 총 유리아미노산은 발효쌀겨의 첨가수준이 높을수록 그 양이 증가하였다. 육의 추출물에서 맛과 풍미에 중요한 역할을 하는 아미노산인 glutamic acid, glycine, alanine(16) 등의 함량이 발효쌀겨를 급여한 돈육에서 증가하는 경향을 나타내었다. 지방산 조성은 처리구와 대조구간 유의적인 차이가 없었으나(p>0.05) stearic acid(C18:0)에서 발효쌀겨의 급여수준에 따라 그 조성이 증가하는 경향을 보였다. 관능평가 검사 결과, 육색, 냄새, 다즙성, 맛, 전체적 기호도에서 처리구가 다소 높은 점수를 얻었으나, 모든 관능검사항목에서 처리구와 대조구 간 유의적인 차이는 없었다(p>0.05). 이상의 결과를 종합하면, 발효쌀겨급여는 돈육의 육질 개선에 효과가 있는 것으로 판단된다.
