Research progress in antioxidant function and stability of blueberry anthocyanins

Blueberry anthocyanin,which is available to prevent oxidative stress injury,possesses the functions of eliminating redical,improving the activity of antioxidant enzymes and inhibiting the antioxidant activity of lipid peroxidation. The exceedingly unstable structure of anthocyanins restricts the development of blueberry as natural antioxidants which are extremely vulnerable to destruction during the process of extraction,purification,production and storage. This thesis comprehensively elaborates the research content from the aspects of blueberry anthocyanin structure categories,the structure-activity relationship of antioxidant function and the stability of anthocyanin extraction,etc.,which was expected to provide reference for further research and utilization of the blueberry anthocyanins.
