Abstract
Fish protein hydrolysate (FPH) was produced from the viscera of beluga (Huso huso). Hydrolysis conditions (enzyme activity, temperature, and time) were optimized using response surface methodology (RSM). Lack-of-fit test revealed a non-significant value for the model, indicating that the regression equation was adequate for predicting the degree of hydrolysis under any combination of the variables (P < 0.05). The optimum conditions to reach the highest degree of hydrolysis were: 39.21 °C, 114.2 min, and a protease (Protamex) activity of 27.41 AU/kg protein. The amino acid composition of protein hydrolysates of beluga in optimum conditions showed a high nutritional value of protein hydrolysates from beluga viscera.
