Abstract
Antioxidant activity of Soybean Dregs Dietary Fiber(SDDF) was discussed by in vitro experiments.Antioxidant activity of SDDF was evaluated by total antioxidant power system and free radical assay systems including hydroxyl,superoxide anion and the DPPH free radical systems.SDDF has a strong scavenging capacity against hydroxyl,superoxide anion free radicals with an EC50 of 4.18 g/L and 8.86 g/L respectively,but the scavenging capacity against DPPH free radicals and the total antioxidant capacity were weaker.The scavenging capacity against hydroxyl,superoxide anion and the DPPH free radicals was weaker than that of vitamin C.However,compared with vitamin C,SDDF has a stronger total antioxidant capacity.SDDF,which has a strong antioxidant capacity,can be used as a natural antioxidant to develop other antioxidant function products.
