Studies on the Extractability and Characteristics of Actomyosin of Duck Muscle by Difference Scalding Method
침탕방법을 달리한 오리근육의 Actomyosin의 추출성과 특성에 관한 연구
Abstract
Investigation on the characteristics of actomyosin was prepared from leg and breast muscle of duck treated by hard scalding and subscalding method and their extractability , ATPase activity , solubility and SDS polyacrylamide gel electrophoresis were compared. The extractability of actomyosin in leg and breast muscle of duck by hard scalding was 7.84 and 39.84mg/g, whereas 4.79 and 28.04mg/g by subscalding respectively. Ca-ATPase activity of breast muscle wash higher than that of leg muscle. In case of leg muscle, hard scalding was higher tan subscalding. Breast muscle showed that subscalding was higher than hard scalding in less than ionic strength 0.08, and was lower than hard scalding in over ionic strength 0.08.Mg-ATPase was great in ionic strength and subcalding was relatively higher than hard scalding. Without regard to be treated method and part, the start point and end point of solubility were like. Hard scalded muscle and breast muscle showed that proteins in thin filament produced many extraction.
오리를 고온침탕법과 중온침탕법에 의해 털을 제거하고 다리 및 가슴부위의 골격근에서 actomyosin을 추출하여 몇가지 특성을 비교하엿다. 고온침탕 처리한 근육으로부터 추출된 actomyosin의 추출성은 다리와 가슴근육이 각각 7.84, 39.48mg/g, 중온침탕한 것은 각각 4.79, 28.04mg/g고온침탕법의 추출성이 더 높았다. Actomyosin의
