Quantification of Multifunctional Dipeptide YA from Oyster Hydrolysate for Quality Control and Efficacy Evaluation

Figure 4

YA content after treatment with pepsin, trypsin and α-chymotrypsin, and carboxypeptidase A compared with that of control (without enzyme treatment). OH, oyster hydrolysate; PE, pepsin; TR, trypsin; CH, α-chymotrypsin; CPA, carboxypeptidase A. The labels with different letters above each bar denote statistical significance (p < 0.05).
