离子迁移谱及其在食品监测中的应用
离子迁移谱(ion mobility spectrometry, IMS)是近年来快速发展起来的一项检测技术。由于其操作简便、检测快速、灵敏度高、体积小等明显优势, 现已被应用到危险品检测、医药、环保、食品安全、过程控制等诸多领域的研究中。本文简要地介绍了其结构和工作原理, 重点阐述其在国内外食品监测领域中的最新进展。目前在食品工业中的应用研究包括: 食品与农产品中农药、兽药等的残留检测, 食品生产加工储蓄保鲜等过程中的质量控制如控制啤酒发酵程度、储藏保鲜过程监测, 食品原产地及真实性的快速检验如橄榄油和葡萄酒等级鉴定、原产地鉴定等。在此基础上也与现行的常规检测技术(高效液相色谱、气相色谱)进行了比较。简要讨论了其在食品安全和质量检测中的可能应用前景, 认为IMS具有提高食品质量、优化生产过程、规范市场行为的巨大潜力。
Ion mobility spectrometry (IMS) is a new powerful detection technology which is fast, simple, high sensitivity, and smart, and has been developed rapidly in recent years. It has been applied to many fields such as hazardous goods detecting, pharmaceuticals, environmental protection, and so on. The structure, working principle and its application were introduced briefly in this article. Its application in food monitoring was emphasized on, including the detection of toxic and harmful substances in food like pesticides, veterinary drugs and so on, as well as the detection of the volatile of foodstuffs. Its application in food industry includes food production process control(like controlling the fermentation of beer), storage process monitoring(choosing the best conditions for food preservation), classification, authenticity identification(distinguishing olive oil and wine from different origins and ranks). At last, it was discussed that the advantages and disadvantages of IMS by comparing with those commonly used detection technology(HPLC and GC). IMS should has a great potential in the fields of food safety and quality control such as improving food quality, optimizing the production process and standardizing the market behavior.
