In this work, we evaluated the occurrence of furan in brews obtained from regular, decaffeinated, and instant coffee and commercial packed capsules. For this purpose, a previously developed automated headspace solid-phase microextraction method coupled to gas chromatography–mass spectrometry (HS-SPME-GC–MS) was used. Initially, the influence of HS-SPME conditions on furan formation was evaluated....
A simple, fast and fully automated method based on headspace solid-phase microextraction coupled on-line with gas chromatography–ion trap mass spectrometry (HS-SPME–GC–ITMS) is proposed for furan determination in foods. The performance of the proposed method was compared to the automated headspace-GC–MS method, proposed by the US Food and Drugs Administration (US FDA), in terms of repeatability, limits...
A headspace-solid-phase microextraction (HS-SPME) coupled to gas chromatography–ion trap mass spectrometry (GC–IT-MS) method is proposed for the analysis of furan in different heat-treated carbohydrate-rich food samples. The extraction efficiency of six commercially available fibres was evaluated and it was found that a 75μm carboxen/polydimethylsiloxane coating was the most suitable for the extraction...
