To investigate the best method of extracting Anthocyanins from Blueberry,raw materials of Blueberry was processed by microwave-ethanol method. On the basis of a single factor design,extraction time,microwave power and ethanol concentration as independent variables,Blueberry anthocyanin extraction yield as the response value,Box-Behnken response surface method was used to research their respective variables and their interactions on the effects of Blueberry Anthocyanin extraction yield. The results showed th...
