Blueberry juice was prepared by enzymolysis of pectinase,cellulase and hemicellulase from blueberry.The enzymolysis conditions were optimized by Box-Behnken response surface method.The results showed that the optimum enzymolysis parameters of blueberry juice were as follows:enzymolysis temperature 50 ℃,enzymolysis time 2.5 h,and compound enzyme ratio 0.15％:0.08％:0.08％.Under these conditions,the enzymolysis effect of blueberry juice beverage was the best.
