摘  要:
文章介绍了果胶酶在欧李果汁加工中的作用,研究发现:欧李果汁澄清中最适的果胶酶添加量为20mg/L,处理温度为30℃,时间为24h。用此工艺生产的欧李果汁,澄清度较高,果胶基本分解完全;在果浆加工中,同样添加量的果胶酶使果汁出汁率提高了12%,果胶含量下降了76.7%。

摘  要:
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%.
