Abstract: A method involving headspace-solid phase micro-extraction (HS-SPME), gas chromatography with flame ionization detection (GC-FID) and gas chromatography with mass spectrometry (GC-MS) was developed and optimized to investigate the volatile composition of Capsicum chili peppers. Five SPME fibers were tested for extraction: carboxen/polydimethylsiloxane (CAR/PDMS-75. μm), polydimethylsiloxane (PDMS-100. μm), divinylbenzene/polydimethylsiloxane (DVB/PDMS-65. μm), carbowax/divinylbenzene (CW/DVB-70. μm), and divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS-50/30. μm), the last of which was shown to be the most efficient fiber to trap the volatile compounds. Optimization of the extraction conditions was carried out using multivariate strategies such as factorial design and response surface methodology. Eighty three compounds were identified by GC-MS when using the optimized extraction conditions, the majority of which were esters. © 2011 Elsevier B.V.
