Determination of 2-Propenal Using Headspace Solid-Phase Microextraction Coupled to Gas Chromatography–Time-of-Flight Mass Spectrometry as a Marker for Authentication of Unrefined Sesame Oil

<div>Chromatograms of 2-propenal in six corn oils (blue line), five soybean oils (red line), and twelve sesame oils (black line) analyzed using GC-TOF/MS (a). Similar MS spectra of 2-propenal in corn oil (b), soybean oil (c), authentic standard (d), and Wiley library (e) were detected at 70 eV of electron energy.</div>
