酶解工艺对籽瓜浓缩汁出汁率的影响

摘要

The seed melon was used as the raw material in the experiment. The application of pectinase, cellulase to increase juice yield in the production of seed melon concentrated juice was studied in this paper through a single factor and an orthogonal experiment. The results showed that the optimum enzymatic hydrolysis processing were as followed: 0.1% pectinase, cellulase 0.05%, Enzyme solution temperature 45℃, enzymolysis time 2h and enzyme solution pH=4.5. On this condition, the yield of juice was 86.3%.%以籽瓜为试验材料，利用果胶酶和纤维素酶进行酶解。通过单因素和正交试验确定籽瓜的最佳酶解工艺：果胶酶0.1%，纤维素酶0.05%，酶解温度45℃，酶解时间2h，酶解pH=4.5。在此最佳酶解条件下，出汁率达86.3%。
