摘　　要：气相离子迁移谱(GC-IMS)是结合了气相色谱和离子迁移谱的新型检测技术,具有操作简便、检测效率高、灵敏度高、不需要前处理等优点。为了提高烟丝加香过程香精在烟丝中的利用率,利用气相离子迁移谱技术研究了不同加香排潮风速条件下烟丝的挥发性香味成分。结合感官评吸、气相离子迁移谱图、差谱图、挥发性香味成分指纹图谱及峰体积强度的研究结果可知,在保证加香雾化效果及加香出口为微负压状态的前提下,降低加香工序排潮风速更有利于香精中的挥发性香味成分施加到烟丝中,有利于增加产品的香气丰富程度,提高产品的润感、降低烟气刺激性,增加口腔生津感。气相离子迁移谱技术实现了烟丝香味成分的快速定性和定量分析,在优化制丝工艺参数、提高烟丝的感官品质等方面具有一定的应用前景。Gas chromatography-ion mobility spectrometry(GC-IMS)is a new detection technology that combines gas chromatography and ion mobility spectrometry.It has the advantages of simple operation,high efficiency,high sensitivity,and no need for pretreatment.In order to improve the utilization rate of the flavors in the cut tobacco during the flavoring process,the GC-IMS technology was used to study the volatile aroma components of the cut tobacco under different exhaust removal wind speeds.Combining the research results of sensory evaluation,gas phase ion mobility spectrum,difference spectrum,fingerprint spectrum of volatile fragrance components and peak volume intensity,it can be known that under the premise of ensuring the atomization effect of fragrance and the state of slight negative pressure at the tobacco outlet,reducing the exhaust removal wind speeds in the flavoring process was more conducive to applying the volatile flavor components in the flavor to the tobacco,which was beneficial to increase the richness of the product's aroma,improve the product's moisturizing feeling,reduce the smoke irritation,and increase the sense of oral fluid.The GC-IMS technology realizes the rapid qualitative and quantitative analysis of the aroma components of cut tobacco,and had certain application prospects in optimizing the process parameters of cut tobacco making to improve the sensory quality of the cut tobacco.
