Study on Antoxidation Activities of Freezing Blueberry Polyphenol

Abstract:

In this study,the antioxidation and deoxidize activity of blueberry polyphenol was studied and compared with VC using the hydrogen peroxide,hydroxyl radical,superoxide radical,nitrite system as index.Results demonstrated that the blueberry polyphenol exhibited different antioxidation activities in these radicals.The scavenging activity to nitrite system and hydroxyl radical was lower,but the hydrogen peroxide system was higher than that of VC.Furthermore,,scavenging activities to deoxidize activity and superoxide radical system were equal to VC.
