Research on the extraction of blueberry juice by enzymolysis method
In order to improve the extraction rate and nutritional quality of blueberry juice,using enzymatic hydrolysis technology,on the basis of single factor experiments,the enzymolysis conditions were optimized by orthogonal experiments,and the juice yield,total soluble solid (TSS) and anthocyanidins content were determinated.The results showed that the optimum enzymolysis extraction process conditions of blueberry juice were pectinase:cellulase 3∶1,enzyme addition 0.20％,enzymolysis time 180 min,temperature 50 ℃.Under the optimum extraction process conditions,the juice yield of blueberry juice was 73.37％,the contents of TSS and anthocyanidins were 11.8 °Bx and 300.7 mg/kg,respectively.
