Abstract

This study was carried out to investigate the effect of carcass weight on the physicochemical and sensory traits of duck meat. In total, 150 duck carcasses were divided into five different weight groups. The fat content in both breast and leg meats tended to increase with increased carcass weight. The cooking loss was significantly higher in the <2,200 g weight group and decreased with increased carcass weight. There was no significant difference in pH, water-holding capacity, lightness, or redness among carcass weight groups. The shear force was significantly higher in the ${\geq}2,800g$ weight group. The oleic acid (C18:1, n9) content in both the breast and leg meats tended to increase with increased carcass weight. The unsaturated fatty acid content in the breast meats was similar for all the groups whereas its content in the leg meats increased with increased weight groups. There was no significant difference in the sensory scores among the treatments. Taken together, it may be said that the carcass weight had minor effects on the physicochemical traits of duck meat. Further studies are needed to determine the effects of different carcass weights in the same raising period on duck meat quality.

본 연구는 오리의 도체중량에 따른 오리고기의 이화학적 특성을 구명하고자 수행하였다. 오리 도체중에 따라 200 g 단위로 2,200 g 미만부터 2,800 g 이상까지 총 5개의 중량구간을 설정하여 가슴육과 다리육을 분석하였다. 일반성분 중 지방은 가슴육에서 중량이 증가할수록 증가하는 것으로 나타났다(P<0.05). pH와 보수력은 중량에 따른 경향이 나타나지 않았다. 가열감량은 가슴육에서 2,200 g 미만 구간에서 가장 높았으며, 중량이 증가할수록 감소하는 경향이 나타났다(P<0.05). 육색은 중량에 따른 경향이 나타나지 않았다. 전단력은 2,800 g 이상 중량구간에서 가장 높게 나타났으며, 중량이 증가할수록 증가하는 경향을 나타내었다(P<0.05). 지방산 조성은 가슴육과 다리육 모두 중량이 증가할수록 oleic acid(C18:1, n9) 함량이 증가하는 경향을 나타내었다(P<0.05). 불포화지방산 함량은 가슴육에서 유의적인 차이가 없었으나, 다리육에서 중량이 증가할수록 증가하는 경향을 나타내었다(P<0.05). 관능평가 결과, 가슴육의 2,800 g 이상 중량구간에서 풍미, 연도와 종합 기호도가 가장 높게 나타났으나, 유의적인 차이는 나타나지 않았다. 이상의 결과를 종합해 보면 오리의 도체중량이 오리고기의 이화학적 특성에 영향을 주었으나, 관능특성에는 유의미한 영향이 없는 것으로 나타났다.
