Furan, which has been identified as possibly carcinogenic for humans, can be induced to different food items by thermal treatment. In accordance with the previous studies and risks associated with prevalence of furan in food, it is necessary to be acknowledged of amounts of furan formed in different thermally processed foods for human awareness. In this study, Headspace Solid-Phase Microextraction Gas Chromatography–Mass Spectrometry (HS-SPME-GC/MS) was optimized for simultaneous determination of furan, furfural, 2-methylfuran and 2-pentylfuran for the first time from different dried fruits and roasted nuts. The method was proved to be valid for determination of all analytes at 50 °C for 25 min, stirring at 700 rpm and 20% NaCl (W/V) using 50/30 μm divinlybenzene/carboxen/polysimethylsiloxane (DVB/CAR/PDMS) fibre. All analytes were baseline-separated at HP 5-MS column in less than 13 min and obtained results have shown prevalence of furan, furfural and 2-pentylfuran in the studied matrices; however, 2-pentylfuran was more prevalent in the roasted nuts than dried fruits and 2-methylfuran has not shown considerable prevalence in both matrices. Moreover, this method was validated in terms of linearity, precision, recovery, specificity, limit of detection and limit of quantification depending on analytes and sample matrices. Hence, the present method was proved to be highly sensitive, specific and robust with good precision and accuracy and suitable for monitoring these furan derivatives in the studied matrices.
