摘  要:
本试验对葡萄酒进行冷冻,生成冰晶,并将浓缩物从冰晶中分离。结果发现,酒精和还原糖比较适于利用冷冻法在液相中进行浓缩分离。通过对单独和连续冷冻两种分离法进行比较,结果表明,在同一冷冻温度下,两种方法分离所得液相部分的浓度和获得率均相同,即对同一种酒来说,液相部分的浓度和得率,与冷冻分离时的温度有关,而与冷冻方法无关。

摘  要:
Wine was treated by cooling,then separated the condensate from crystal.The results showed that sugar and alcohol were easies to be separated from the wine than other components.Treated wine by single-cooling method and continual-cooling method indicated that the concentration and recover rates of liquid-phase part of wine were equivalent at same temperature.This is to say that the concentration and recover rates of liquid-phase part in the same wine are related with cooling temperature,no relation with cooling method.
