Application of gas chromatography-ion mobility spectrometry technology in the origin traceability of animal and plant-derived foods
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.
