Abstract Plaice by-products （head, skin and bones） were hydrolyzed by alcalase and functional properties of resultant hydrolysates with different degrees of hydrolysis between 9.0% and 23.4% were measured. At constant pH, the solubility of plaice by-product hydrolysates increased as the degree of hydrolysis increased from 15%. After treatment at 93℃ for 10 min, the solubility of plaice by-product hydrolysates with 11.3%, 17.2%, 21.7% and 23.4% degrees of hydrolysis remained above 90%. At pH 4 and 7, the emulsifying activity index （EAI） of plaice by-product hydrolysates reached the maximum level at the degree of hydrolysis of 23.4%. These results indicate that degree of hydrolysis and pH can influence functional properties of plaice by-product hydrolysates.
