The blueberry pomace was analyzed as the extracted material to study the optimum procedures of the enzymatic-ultrasonic-assisted extraction method.The single factor experiments were emplyed.The optimum procedures of the enzymatic-assisted ultrasonic extraction were as follows:cellulose,enzyme temperature 50℃,enzyme amounts 5 mg·g-1,solid to liquid ratio 1:10,ultrasonic incubao tion power 200 W,time 20 min.Afterwards,ethanol(final concentration 40％)was added to the mixture for ultrasonic-assisted extracting 20 min with the power of 250 W.The absorbance of anthocyanins extracts from blueberry pomace was the highest under these conditions.The method was time-saving.solvent saving and high extraction yield.so it can be used for the maximum of anthocyanins from blueberry resource.
