Comparison of Pepper samples with SPME-GCxGC-TOFMS
Pepper contains a lot of volatile and semi-volatile organic compounds. In this study, we aim to compare pepper samples and understand differences by determining individual analyte differences. Gas chromatography (GC) is a useful tool for these types of chemical analysis as volatile and semi-volatile analytes are readily separated. For complex samples, however, the wide range of analytes contributing to the aroma profile can be difficult to separate with GC alone. In these instances, comprehensive two-dimensional GC (GCxGC) can be very useful. In this work, GCxGC system is paired with a time-of-flight mass spectrometer (TOFMS) for pepper aroma profiling. The pepper samples were compared and representative individual analyte differences, some that were obscured by first dimension coelutions, are presented here.
