摘  要:
以米枣为原料,探讨米枣热烫、果胶酶澄清主要加工工艺参数。采用单因素试验、组合试验和正交试验确定热热烫最佳条件95℃、3min,在此条件下米枣汁褐变指数为0.124,出汁率为56.0%;果胶酶澄清的最适条件为果胶酶用量0.12g/100mL、酶解温度45℃、酶解时间2.5h、酶解pH3.5。在此条件下所得米枣汁澄清度为93.24%,浊度为78.32,果胶试验为"-"。

摘  要:
The clarification of ‘Mi Zao' jujube juice was investigated using blanching followed by pectin treatment.The optimum blanching conditions were determined as 95 ℃ and 3 min,and the browning index of the jujube juice blanched under the optimized conditions was 0.124 and juice yield was 56.0%.The optimum enzymatic treatment conditions were found to be an enzyme dosage of 0.12 g/100 mL,55 ℃,2.5 h and pH 3.5.After the optimized treatment,the clarity and turbidity were 93.24% and 78.32,respectively,and pectin test was negative.
