摘　　要：本文综述了渗透汽化技术在酒类加工过程中脱醇及香味物质分离中的进展。研究表明,脱醇中PDMS为主要选用膜材料,并通过在PDMS中掺杂二氧化硅、MOF等材料改性提升其稳定性与分离效率;PEBA膜也表现优异,共混改性后渗透通量提升。香味物质分离中,PDMS与PEBA分别因其有机物亲和力和对酯类高选择性被广泛应用,改性策略进一步优化分离性能。此外,新型材料如GO、PIM等也表现出相当大的潜力。渗透汽化技术具有高选择性、低能耗及低温操作等优势,但渗透通量偏低是待改进之处。未来需研发新型膜材料、优化改性方案以促进其在酒类加工方面的应用。The advancements in the application of pervaporation technology for alcohol removal and aroma compound separation in alcoholic beverages was reviewed in this article.Research indicated that PDMS membrane materials were primarily used for dealcoholization,with doping modifications such as silica and MOF fillers enhancing their stability and separation efficiency.PEBA membranes also exhibited excellent performance,with blending modifications boosting permeation flux.In aroma separation,PDMS and PEBA were widely applied due to their organic affinity and high selectivity for esters,respectively,with further optimizations through modifications.Novel materials like GO and PIM showed great potential.Pervaporation technology stood out for its high selectivity,low energy consumption,and low-temperature operation,but low permeation flux remained a challenge.Future research should focus on developing new membrane materials and optimizing modification techniques to facilitate wider industrial applications.
