Proteinases from liver extract from albacore tuna (Thunnus alalunga) were used to produce protein hydrolysate from starry triggerfish (Abalistes stellaris) muscle. Hydrolysis conditions for preparing protein hydrolysate from starry triggerfish muscle were optimized. Enzyme level, reaction time and fish muscle/buffer ratio significantly affected the hydrolysis (p &lt; 0.05). Optimum conditions for triggerfish muscle hydrolysis were 5.5 % liver extract, 40 min reaction time and fish muscle/buffer ratio of 1:3 (w/v). The freeze-dried protein hydrolysate was characterized with respect to chemical composition, amino acid composition and color. The product contained 91.73 % protein, 2.04 % lipid and 6.48 % ash. The protein hydrolysate exhibited high amount of essential amino acids (45.62 %). It was light yellow in color (L (*) = 82.94, a (*) = 0.84, b (*) = 22.83). The results indicate that the extract from liver of albacore tuna could be used to produce fish protein hydrolysate and protein hydrolysate from starry triggerfish muscle may potentially serve as a good source of desirable peptide and amino acids.
