中文摘要:

      食品产地溯源技术对于有效开展食品原产地追溯、保护地方品牌和特色产品具有重要的意义。我国已建立了包括“中国农产品地理标志”在内的多个食品安全标准体系。随着时间的推移, 国内外对食品产地判别的需求日益增加, 挥发性有机化合物(volatile organic compounds, VOCs)特征与食品产地密切相关, 可用于表征不同产品同种食品间的差异。气相色谱-离子迁移谱(gas chromatography-ion mobility spectrometry, GC-IMS)技术是近年来发展起来的用于VOCs测定的新技术, 具有分离效果好、检测速度快、灵敏度高优点, 有潜力成为有效的产地溯源技术手段。本文介绍了GC-IMS技术的工作原理和特点, 总结了近年来GC-IMS技术在动植物源食品产地溯源中的应用进展, 探讨了GC-IMS技术未来的发展方向, 以期为GC-IMS技术在食品产地溯源中应用的持续拓展提供技术参考。

英文摘要:

      Food origin traceability technology is an important technical means for the effective implementation of food origin traceability and the protection of regional brands and specialty products. China has established a number of food safety standard systems, including “geographical indications of Chinese agricultural products”. There is an increasing demand for food origin discrimination at home and abroad, and the characteristics of volatile organic compounds (VOCs) are closely related to food origin, which can be used to characterize the differences between different products of the same kind of food. Gas chromatography-ion mobility spectrometry (GC-IMS) technology is a new technology developed in recent years for the determination of VOCs, which has the advantages of good separation effect, fast detection speed and high sensitivity, and has the potential to become an effective technical means for origin tracing. This paper introduced the working principle and characteristics of GC-IMS technology, summarized the progress of the application of GC-IMS technology in the origin traceability of animal and plant-derived foods in recent years, and discussed the future development direction of GC-IMS technology, in order to provide technical reference for the continuous expansion of the application of GC-IMS technology in the origin traceability of food.
