Abstract: In the paper fish protein was hydrolyzed by proteases for preparing fish peptide. The optimum hydrolysis conditions for alcalase are as follows: concentration of fish protein 30%, pH9.0, 50 ℃, ratio of alcalase to fish protein 48 AU/kg, time 120 min. Under these conditions, 76.48%(W/W) of fish peptides with 72.81% purity. Fish peptides with better solubility can be extensively used in the food.
