摘　　要：低度白酒除浊的方法有冷冻过滤法、吸附法、膜滤法、超滤法、离子交换法、再蒸馏法、增溶法、臭氧催化法等。对中小型白酒企业而言,常用活性炭吸附法,使用活性炭的关键是用量、处理时间和处理酒的酒精度。研究了酒类专用炭的除浊效果以及对低度白酒香味的影响;确定了酒类专用炭进行低度浓香型大曲酒除浊的最适工艺条件:最佳用量1.5‰,最适处理时间24h,处理酒的适宜酒精度为60%vol。Turbidity removal methods of low-alcohol liquor cover frozen filtration,absorption,membrane filtration,ultrafiltration,ion exchange technique,re-distillation,increasing dissolution and ozone catalytic method etc. For middle and samll-scale liquor-making enterprises, active carbon absorption is a common method. The key points of active carbon absorption are the use level of active carbon, treatment time and the alcoholicity of treated liquor. In this paper, the turbidity removal effects of active carbon and its influence on liquor aroma were studied. The optimum technical conditions in turbidity removal of Daqu liquor were summed up as follows： the best use level of active carbon was 1.5 ‰,the optimum treatment time was 24 h, and the suitable alcoholicity of treated liquor was 60 %vol.
