  • 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.
