Research Progress on the Application of Gas Chromatography-ion Mobility Spectrometry in the Field of Tea
Tea is an important economic crop in traditional Chinese agriculture,with a long history and rich cultural connotation. The different parameters of tea origin,storage time and processing method determine the quality,nutritional value and market positioning. Known as a newly developed non-destructive testing technique,GC-IMS can analyze the volatile organic compounds (VOCs) of samples under normal pressure to characterize the differences between samples. This paper collected the existing literature data,reviewed the applications of GC-IMS technology in the study of kind differentiation,grade identification,origin identification,storage time determination and processing quality control of tea,and analyzed the current problems and future prospects of GC-IMS technology in the field of tea application,and provided theoretical reference for the flavor research,process optimization,quality analysis and quality monitoring of tea.
