Figure 1. Changes in DH during sequential in vitro digestion of Radix Isatidis protein hydrolysate (RIPH). The first stage: from 0.0 to 2.0 h, digested by pepsin; the second stage: from 2.0 to 4.0 h, digested by pancreatin. The data with different lowercase letters are significantly (P < 0.05) different.
