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
