Abstract: The effects of pectinase in Cerasus Humilis juice processing were studied in this paper. The results showed that the optimum conditions of adding pectinase were: 20/L, treated at 30℃ for 24h. At these conditions, the clarity of juice is better, and the pectin is decomposed completely. When the same dosage was applied to Cerasus Humilis jam, the yield of juice increases 12%, and the content of pectin decreases 76.7%.

Key words: pectinase, Cerasus Humilis juice, application
