[Objective] To provide references for the quality evaluation of coffee beans in different production areas.[Methods] Volatile components in coffee beans from different production areas were analyzed by headspace solid-phase micro-extraction( HS-SPME) and gas chromatography-mass spectrometry( GC/MS).The relative contents of volatile components were calculated by peak area normalization method,and processed by stoichiometry.[Results] A total of 97 chemical components were preliminarily identified.There were certain differences in the volatile components in coffee beans from different production areas.Coffee beans from three production areas( Brazil,Columbia and Indonesia)were analyzed by principal component analysis and cluster analysis.[Conclusions] This method was suitable for the rapid analysis of volatile components in coffee beans,which could be used for the quality evaluation of coffee beans.
