摘　　要：气相色谱-离子迁移谱法(gas chromatography-ion mobility spectrometry, GC-IMS)结合了气相色谱的高分离能力和离子迁移谱的高灵敏度,可得到保留时间、漂移时间和信号强度的三维谱图,使定性分析更加准确,有效地解决了气相色谱低鉴别能力和离子迁移谱对混合物进行检测时存在的交叉灵敏度问题,并且不需要复杂的样品前处理,可以直接对样品的挥发性有机化合物(volatile organic compounds,VOCs)进行分析,极大简化了分析过程,实现快速检测,满足现场分析的需要。作为一项新兴的无损检测技术,GC-IMS目前主要应用于食品质量鉴定、掺假溯源分析、食品特征风味分析、新产品开发等方面。本文介绍了GC-IMS的基本原理,重点综述了GC-IMS在粮油、果蔬、水产品等农产食品中应用的研究现状,以期为农产食品的品质分析、风味研究、新食品开发等提供一定的理论指导。Gas chromatography-ion mobility spectrometry(GC-IMS) combines the high separation power of gas chromatography with the high sensitivity of ion mobility spectrometry to obtain the three-dimensional spectra of retention time, drift time and signal strength, which makes the qualitative analysis more accurate, it effectively solves the problems of low identification ability of gas chromatography and cross sensitivity of ion mobility spectrometry in the detection of mixtures, the volatile organic compounds(VOCs) of the samples can be directly analyzed without complex sample pretreatment, greatly simplifying the analysis process, achieving rapid detection, and meeting the needs of on situ analysis. As a new non-destructive testing technology, GC-IMS technology is mainly used in food quality identification, adulteration traceability analysis, food flavor analysis, new product development and other aspects. This paper introduced the basic principles of GC-IMS, and emphatically summarized its application on several kinds of food, such as grains and oils, fruits and vegetables, aquatic products and so on, aiming to provide some theoretical guidance for the agro-food quality analysis, flavor research and new food development of edible agro-food products.
