DPPH radical-scavenging capacities by pepsin hydrolysates of P-CMP, P-CWP, P-CCP and their RP-HPLC peptide peaks (200 μg/mL). Thin layer chromatography (TLC) blot assay on a silica gel TLC plate stained by spraying with 1.8 mmol/L DPPH solution in ethanol, and visualized for the presence of whitish spots, indicating anti-oxidant activity. DPPH = 2,2-diphenyl-1-picrylhydrazyl; P-CMP = pepsin digested camel milk proteins; P-CWP = pepsin digested camel whey proteins; P-CCP = pepsin digested camel casein proteins.
