摘　　要：低度白酒是21世纪白酒消费的主流,但白酒在降度过程中不可避免地出现失光、浑浊、口味寡淡等现象,如何使白酒在降度过程中保持原有的典型风格,达到"低而不浑、低而不寡",是人们关注的焦点,也是研究的热点。采用活性炭吸附法对53%vol张弓浓香型白酒降到40%vol过程中出现的浑浊问题进行了研究。结果表明,采用孔径为2.8 nm以上的活性炭作为吸附介质,添加量为0.12%,处理时间为96 h时,能够达到保持张弓浓香型大曲原有典型风格的最佳效果。Low-alcohol liquor has become the consumption mainstream in the 21 st century. However, during the process of reducing liquor alcoholicity, light loss, turbidity and boring taste are inevitable phenomenons. How to keep original liquor styles has become the research hotspot. In this experiment, active carbon absorption was applied to treat the turbidity occurred in alcoholicity-reducing process of Zhang＇gong liquor （53 % vol reduced to 40 %vol）. The results showed that its original styles could be well kept under the following conditions： active carbon （aperture above 2.8 nm） used as absorption medium, the addition level of active carbon was 0.12 %, and the processing time was 96 h.
