Study on the Antioxidant Activity of Sesame Residue Protein Peptides
In this study,the effect of different proteases on the hydrolysis degree of sesame protein extracted from sesame residue.The results showed that neutral protease,Papain and flavor protease had higher degree of hydrolysis of sesame protein,while neutral protease had the highest degree of hydrolysis,reaching 10.54％,and alkaline protease had the lowest degree of hydrolysis,only 2％.The antioxidant activity of sesame protein peptides after hydrolysis was measured,and it was found that sesame protein peptides exhibit strong ability to scavenge DPPH,superoxide anions,ABTS+·,and hydroxyl radicals,indicating that sesame protein peptides have strong antioxidant activity and are a potential antioxidant agent.
