Abstract:Crude protein of abalone viscera was used as raw material and papain was used as a tool enzyme to carry out high-performance enzymatic hydrolysis. The optimum enzymolysis process was obtained based on the index of the degree of hydrolysis and antioxidant capacity by optimizing the enzymolysis process through orthogonal experiments，namely pH 9，1 000 U/g of enzyme/substrate，60 ℃ of enzymolysis temperature，5 % of substrate concentration，（88.14±0.92）% of the DPPH radical scavenging rate of enzymatic hydrolysateand （14.12±0.53）% of the degree of hydrolysis；the food grade activated carbon powder was used as absorbents to obtain the optimum dehydration technology of the enzymatic hydrolysis solution based on the indicators of protein loss rate and sensory evaluation including 1.0 % of mass fraction of activated carbon，60 min of adsorption time and 50℃of adsorption temperature. In this experiment，the protein recovery was （88.06±0.24）% and the odor value was 2.00. The obtainedenzymatic hydrolysis solution had a strong anti-oxidation capability and the deodorizing solution in pale yellow didn't have obvious bitter and fishy smell with improved sensory quality.
