WebbProtein hydrolysates (PH) were prepared according to the method of Noman et al. ( 2024) with minor modifications. The sodium phosphate buffer was used to keep the pH constant during the incubation time. The layout of the hydrolysis process is presented in Figure 1. Webbprotein hydrolysis. If so, the results of the determination will be in°uenced adversely. Various studies reported that the degree of racemization during hydrolysis of peptide is dependent on protein type and amino acid background. It was found [26, 35, 41, 50] that amino acids bound in peptide racemize faster than free amino acids.
