Botanical and geographical origin characterization of polish honeys by headspace SPME-GCxGC-TOFMS
PublikacjaVolatile organic compounds (VOCs) composition of Polish honeys obtained from various geographical regions was studied. Headspace solid phase microextraction (HS-SPME) using Divinylbenzene/Carboxen/Polydimethylsiloxane-coated fibers was used in combination with comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC× GC-TOFMS) because of the complexity of the samples. Acacia, linden, rapeseed, buckwheat...
