A novel dynamic approach is described to profile volatile organic compound (VOC) and semi-VOC (SVOC) emission during coffee roasting aimed at analysing components present in the roasting plume, and to monitor their evolution during the process. Two sorbents ? coconut shell charcoal (CSC) and styrene-divinylbenzene resin (XAD-2) ? were evaluated while collecting substances in four sequential time intervals (0?3, 3?6, 6?9 and 9?12?min). Extracted VOCs (<200?Da) and SVOCs were analysed by gas chromatography (GC), and comprehensive two-dimensional gas chromatography (GC?×?GC) with flame ionisation (FID) and time-of-flight mass spectrometry (TOFMS) detection. Results showed CSC extraction presented poor recovery of VOCs and SVOCs released during roasting. However, XAD-2 was able to collect both groups, including SVOCs of >400?Da. GC?×?GC resolved many co-eluting compounds observed in 1D GC and allowed chemical group type cluster analysis, revealing that many non-polar VOCs are observed within the 0?3?min interval, and that the release of polar and higher molar mass SVOCs were mostly found within the 3?6?min interval. These group-type cluster analyses offer a broad spectrum chemical profile of the released substances. It may also reveal detailed insights into the roast process evolution over time. |
