Empirical evidence proves that the antioxidant property plays a main role in the biological activities of biomaterials, which is influenced by several factors. In order to explore in-depth, the influence of ionic systems on the antioxidant activity of collagen peptides was studied. Type-I-collagen peptides (GBB-10SP and TYPE-S) contained a high amount of hydrophobic amino acids and possessed good antioxidant activity at high concentrations in water. On the other hand, increasing [H+] and [Na+] concentrations (0.1 M to 0.5 M) decreased the reducing power of GBB-10SP and TYPE-S; however, [Ca2+] had no effect on the reducing power. Interestingly, the hydroxyl radical scavenging rate of these two peptides was increased by [Na+], decreased by [H+], and [Ca2+] had no effect. In general, TYPE-S showed better antioxidant properties than GBB-10SP. Overall, the above results confirmed that the antioxidant capacity of collagen peptides was affected by [H+] and [Na+] and not by [Ca2+].
