酶解法去除宣木瓜中单宁酸

The tannase remove tannic acid in Papaya

采用酶解法去除宣木瓜中的单宁酸。对影响反应的工艺参数如加酶量、酶解温度、时间、和pH进行了研究,确定了最佳工艺条件。结果表明,单宁酶的最佳作用条件为加酶量为0.2g,水解温度30℃,酶解时间40min,pH 4.5,酶解后宣木瓜汁中剩余单宁酸含量可降低为0.390mg/mL。

Technologic parameters influencing reaction including enzyme amount,temperature,digestion time,and pH were studied using enzyme hydrolysis to remove tannic acid in Papaya.The optimum technologic condition was confirmed.Result showed that the optimum condition for tannin enzyme was 0.2g adding amount of enzyme,30℃ digestion temperature,40 min digestion time and pH 4.5.After enzyme digestion,tannic acid amount was dropped from 1.06mg/mL to 0.390mg/mL.
