Abstract

Analysis of roasted coffee bean volatile organic compounds (VOCs) was performed using person-portable gas chromatography-toroidal ion trap mass spectrometry (ppGC-TMS). Chromatographic separation performance and mass spectra were compared and contrasted with benchtop gas chromatography-quadrupole time-of-flight mass spectrometry (GC-QTOFMS) and gas chromatography-quadrupole mass spectrometry (GC-QMS). The tentative identification of about 50 analytes was established in benchtop analysis, based on accurate MS data, MS spectrum matching and retention indices, and con-trasted with 20 individual analyte peaks similarly recognised in ppGC-TMS analysis. This study suggests the suitability of ppGC-TMS analysis for rapid coffee VOC profiling with minimal sample preparation, using selective key chemical markers, with potential use for on-site process monitoring and roasting optimisation.(c) 2022 Elsevier B.V.
