Abstract
Paphia undulate was used to prepare low-molecular peptides by enzyme autolysis. The optimum condition for autolysis was studied to reach a maximum yield of peptides. Results showed that the yield of low-molecular peptides was 4.33% and 78.57% of the total protein can be recovered under the optimized condition: pH 6.5, temperature 45 Degrees Celsius, reaction time 4h, ratio of starting material and water 1:3 and the enzyme dosage of 1374.0 U/g.
