摘　　要：采用优先透醇膜分离技术净化尾酒(46%vol左右),研究渗透液的感官指标、酒精度、总酸、四大酯的变化。结果表明,在渗透温度45℃、70%提取率时,渗透液酒精度可达65%vol,微量成分含量趋于合理,达到清除尾酒杂味、香味富集、增己降乳的目的,品质显著改善。Ethanol-permselective membrane separation technology was applied for tail liquor （46%vol） purification. The change in sensory index- es, alcoholicity, total acids content, and four main esters of penetrating tail liquor was studied. The results showed that, as the penetrating tempera- ture was at 45℃ and the extracting rate was 70 %, alcoholicity of penetrating tail liquor could reach up to 65 %vol, and off-flavor of the treated tail liquor was eliminated and its quality got improved significantly （ethyl caproate content increased and ethyl lactate content decreased）.
