DETECTION METHOD FOR ORIGIN DETERMINATION BASED ON GAS CHROMATOGRAPHY-ION MOBILITY SPECTROMETRY (GC-IMS)

摘要

A detection method for origin determination is provided. A gas chromatography-ion mobility spectrometry (GC-IMS) technology is adopted to obtain GC-IMS diagrams by detecting types and contents of volatile organic compounds in fruits. After analysises, fingerprint diagrams and principal component analysis (PCA) diagrams of the volatile organic compounds in the fruits are obtained. Origins of fruits can be determined based on the fingerprint diagrams and the PCA diagrams. By datumizing the traditional smelling method, it can assist scientific researchers and producers or businesses to identify origins or specific producing areas of fruits.
