Abstract

Abstract

In this paper,sunflower meal protein powder was used as raw material,before using alkaline protease and papain enzymatic hydrolysis,used microwave pretreated it. Antioxidant activity was investigated to optimum pretreatment process through single factor and response surface method. The results showed that the optimal pretreatment conditions were as followed:microwave time 3min,microwave power 500 W,microwave temperature of 57℃. Under this condition,the scavenging of sunflower meal peptides on O2-· and OH-· were 72.78% and54.13%.
