传统蒸馏工艺存在热敏性成分降解、分离精度低等问题。分子蒸馏具有低温和高效分离的特性。采用分子蒸馏技术，对3种典型烟草精油成分的分离进行了系统研究。结合气相色谱-质谱联用与感官评价技术，构建了“梯度蒸馏-香气物质变化”双参数调控模型。相较于传统工艺，该技术使香气物质保留率提升32%，同步实现1-氨基蒽、2-溴乙醇等有害物质的截除率达100%。揭示了分子蒸馏过程中香气物质的迁移规律，为烟草制品减害增香提供了基础数据。
Abstract：Traditional distillation processes suffer from issues such as degradation of thermosensitive components and low separation accuracy. Molecular distillation offers the advantages of low-temperature operation and highly efficient separation. Employing molecular distillation technology, a systematic investigation was conducted into the separation of 3 typical tobacco essential oil components. Integrating gas chromatography-mass spectrometry with sensory evaluation techniques, a dual-parameter control model linking “gradient distillation to aroma compound changes” was established. Compared to conventional methods, this technology enhanced the retention rate of aroma substances by 32%, while achieving 100% removal of harmful substances such as 1-aminoanthracene and 2-bromoethanol. It elucidated the migration patterns of aroma compounds during molecular distillation, providing foundational data for harm reduction and flavour enhancement in tobacco products.
