Fruit juice production usually requires clarification,and pectinase is the main method of fruit juice clarification.In recent years,Guangxi passion fruit industry has developed rapidly,and Guangxi has become one of the largest passion fruit producing area in China.In order to solve the problems of low fresh fruit value and short shelf life of passion fruit,increase the added value of passion fruit and enrich the product of passion fruit,the optimum production conditions of pectinase clarified passion fruit juice were determined by single factor and orthogonal test.The results showed that under the conditions of pH=4.0,pectinase dosage of 120 mg·kg-1,enzymolysis temperature 45℃and enzymolysis for 140 min,the clarity of passion fruit juice was the best,and the light transmittance reached 84.5%.
