摘　　要：采用渗透汽化膜对酒尾进行浓缩提质,对渗透液进行感官鉴评和气相色谱分析。结果表明,随着过滤时间增加,渗透液中酸类物质和乳酸乙酯均先降低后逐步提升,酯类、醇类和醛类均先升高后降低;分析对比原液、渗透液和余留液的色谱数据,发现原液中绝大部分醇类和酯类均能提取到渗透液中,大部分的乳酸乙酯和酸类物质仍留在余留液中,其中乙醇、醇类、酯类(不含乳酸乙酯)、酸类物质的平均回收率分别是89.59%、95.93%、93.13%、30.97%;感官鉴评结果表明,此方法消除了酒尾的异杂味,实现了酒尾浓缩提质的目的。In this study the pervaporation membrane was used to concentrate the liquor tails,and sensory evaluation and gas chromatography analysis were conducted on the permeate.The results showed that as the filtration time increased,the acids and ethyl lactate in the permeate first decreased and then gradually increased,while esters,alcohols,and aldehydes first increased and then decreased.Analyzing and comparing the chromatographic data of the original solution,the permeate,and the residual solution,it was found that the vast majority of alcohols and esters in the original solution were extracted into the permeate,while the majority of ethyl lactate and acids remained in the residual solution.The average recovery rates of ethanol,alcohols,esters(excluding ethyl lactate),and acids were 89.59%,95.93%,93.13%,and 30.97%,respectively.Sensory evaluation showed that the unpleasant taste of the liquor tail was eliminated,achieving the goal of quality improvement of the liquor tail.
