离子交换树脂314对荔枝酒的降酸处理研究

Study on the Deacidifying Condition of Litchi Wine by Ion-exchange Resin 314

摘要:

采用正交实验法研究离子交换树脂314对荔枝酒的降酸效果，试验结果表明，离子交换树脂314的最佳降酸条件为：固液比为1:10，搅拌速率为200 r/min，处理时间为60 min。在此条件下处理荔枝酒，并用酒石酸回调总酸，挥发酸含量为0.35 g/L，效果理想。

Abstract:

The deacidifying conditions by ion-exchange resin 314 were investigated by orthogonal experiments. The optimal parameters were that the ratio of ion-exchange resin 314 to wine, stirring rate and time were 1:10, 200 r/min and 60 min, respectively. It was proved that ion-exchange resin 314 could decrease volatile acid effectively. When the total acid of Litchi wine got the certain concentration, the mass fraction of volatile acid was 0.35 g/L
