Soğuk pres ayçiçeği yağı termal ve fotooksidasyona tabi tutulmuştur. Bu koşullar altında oksidasyonun izlenmesinde peroksit değeri (PD) ve konjuge dien değeri (K232) kullanılmıştır. Bu klasik oksidasyon testleri yanında, termal ve fotooksidasyon süresince yağlardaki uçucu oksidasyon bileşenleri verileri tepe boşluğu-katı faz mikro-ekstraksiyon (HS-SPME) ve gaz kromatografi-kütle spektrometresi (GC-MS) yöntemi kullanılarak toplanmıştır. 60°C sıcaklıkta termal oksidasyon koşullarında depolama sonunda, PD ve K232 değerleri sırası ile 79.68 meq O2/kg ve 20.03’e kadar arttığı bulunmuştur. Termal oksidasyon süresince 6 uçucu oksidasyon bileşeni (hekzanal, 2-hekzenal, 2-heptenal, E-2-oktenal, E,Z-2,4-dekadienal ve E,E-2,4-dekadienal) belirlenmiştir. Fotooksidasyon sonunda, PD ve K232 değerleri sırası ile 116.97 meq O2/kg ve 22.53 olarak tespit edilmiştir. Fotooksidasyon koşulları süresince belirlenen tek uçucu oksidasyon bileşeni hekzanal da en azından diğer bulgular ile aynı derece önemlidir.

Cold pressed sunflower oil was exposed to thermal and photooxidation, and under these conditions, the values of peroxide (PV) and conjugated diene (K232) were used to follow lipid oxidation. In addition to the classical oxidation tests, the data of volatile oxidation compounds in the oils throughout the thermal and photooxidation were collected by employing HS-SPME (headspace–solid phase microextraction) coupled with GC-MS (gas chromatography–mass spectrometry). Under the thermal oxidation conditions at 60°C, the values of PV and K232 increased up to 79.68 meq O2/kg and 20.03 at the end of storage, respectively. Six volatile compounds (hexanal, 2-hexenal, 2-heptenal, E-2-octenal, E, Z-2,4-decadienal and E,E-2,4-decadieanal) were determined during the thermal oxidation. At the end of photooxidation conditions, PV and K232 values of oils were detected as 116.97 meq O2/kg and 22.53, respectively. It is at least equally important as the other findings that the hexanal was only detected volatile oxidation compound under photooxidation conditions.
