Abstract:

The present study was aimed at optimizing the ultrasonic-assisted enzymatic hydrolysis of Paphia undulata muscle for producing short-chain peptides using response surface analysis based on a series of single-factor investigations. By means of the principles of Box-Benheken central composite experimental design, a four-variable, five-level response surface analysis was designed to discuss the effects of ultrasonic treatment time and power, hydrolysis temperature and solid/liquid ratio on shortchain peptide production. The optimal levels of these four process conditions were determined as follows: ultrasonic treatment time, 4 h; hydrolysis temperature, 55 ℃; ultrasonic power, 140 W; and solid/liquid ratio, 1:2 (g/mL). The experimental value of peptide yield was 5.15%, 1.1-fold higher than that obtained without ultrasonic assistance.
