Abstract：T he effects of ultrasound tenderization of spent laying duck pectoralis muscle w ere studied in different powers and ultrasound treatment times .The results indicated that the amount of heat‐solute colla‐gen in the pectoralis muscle were increased by the ultrasound treatment ,but solution of collagen by ultra‐sound treatment resulted in the disruption of myofibrillar integrity w hich led to the reduced shear force of the muscle .The ultrasound power and ultrasound treatment times were two important factors in the deter‐mination of the tendered effect .The optimum conditions for ultrasound tenderization of spent laying duck pectoralis muscle under the experimental conditions were 300 W of power and 20 min of the treatment time ,respectively .The results of correlation analysis demonstrated that there were negative correlation between activity of heat‐solute collagen and the shear force of the muscle .
