ANALYSIS OF VOLATILE ALDEHYDES IN OAT FLAKES BY SPME-GC/MS

A headspace solid-phase microextraction (HS-SPME) procedure followed by gas chromatography coupled with mass spectrometry (GC/MS) has been developed for the determination of volatiles formed during oxidation of polyunsaturated fatty acids in oat samples. Several SPME coatings were tested and DVB/CAR/PDMS (divinylbenzene/ carboxen/ polydimetylosiloxane) was chosen as the most appropriate for the analysis of these analytes. Experimental SPME parameters such as selection of coating, extraction temperature and time, addition of water and grinding were studied. The elaborated method enabled the qualitative and quantitative analyses of volatile aldehydes in fresh and aged samples. The concentration of total aldehydes, excluding hexanal, which was the predominant volatile carbonyl compound, ranged from 67±3 to 133±5 μg/kg in fresh and from 137±4 to 398±12 μg/kg in aged samples.
