Abstract

Tea is one of the most consumed beverages in the world and its quality is influenced by geographical origin, variety and production methods. The profiling of volatile compounds (VOCs) has been investigated by headspace solid phase micro-extraction coupled with gas chromatography–mass spectrometry (HS-SPME/GC–MS) analysis and applied for the discrimination of Vietnamese green teas from different geographical origins. The VOCs were extracted from the dried tea leaves by headspace solid-phase microextraction procedure and followed by GC–MS analysis. Tea samples from different origins were correctly discriminated according to their GC–MS profiling of VOCs by principal component analysis and cluster analysis. Our results demonstrate that the developed method in this study can be used to discriminate the Vietnamese green tea samples from different geographical origins with high reliability.
