Özet
Yağ üretimi açısından önemli olan Ege bölgesi illerinden (Muğla, Aydın, İzmir ve Manisa) Gemlik, Memecik, Ayvalık, Uslu ve Domat zeytin çeşitlerinden 2007-2008 ve 2008-2009 dönemi olmak üzere 2 yıl hasat edilmiştir. Hasat edilen zeytinler laboratuvar tipi santrifüj sistem kullanılarak yağa işlenmiştir. Tepe boşluğukatı faz mikroekstraksiyon (HS-SPME) yöntemi yardımı ile yağlardan uçucu aroma bileşenleri ekstrakte edilerek gaz kromatografi-kütle spektrometre (GC-MS) cihazı ile bileşenlerin kalitatif ve kantitatif analizi yapılmıştır. Bu çalışmada, zeytinyağı kalitesi ile ilişkili olan altı karbonlu bileşenler belirlenmiştir. E-2-hekzenal ve hekzanal, çalışılan yağ örneklerinde en fazla oranda bulunan bileşenlerdir. 2007-2008 ve 2008-2009 hasat döneminde E-2-hekzenal bileşeninin sırası ile % 13.05-67.15 ve % 23.03-52.44 aralığında olduğu belirlenirken aynı hasat dönemlerinde % 6.70-39.34 ve % 11.23-59.81 arasında tespit edilen hekzanal bileşeninin, en yüksek salınan uçucu bileşenler arasında ikinci sırada yer aldığı görülmüştür
Gemlik, Memecik, Ayvalık, Uslu and Domat olive cultivars were harvested from Aegean region provinces (Muğla, Aydın, İzmir ve Manisa) being important in terms of the oil productions of the Aegean region for two harvest periods as 2007-2008 and 2008-2009. The olives harvested are processed to olive oils using laboratory scale centrifuge system. With the aid of the headspace-solid phase microextraction (HS-SPME) technique the qualitative and quantative analyses of compounds were accomplished with the gas chromatography-mass specrometer (GC-MS) by extracting the volatile compounds of oils via. In the present study, C6 compounds related to the quality of olive oil were determined. E-2-hexenal and hexanal were found to be most abundant compounds in the oil samples studied. In 2007-2008 and 2008-2009 harvest periods, E-2-hexenal (the most found component) was determined to be in a range of 13.05-67.15% and 23.03-52.44%, respectively whereas hexanal detected between 6.70-39.34% and 11.23-59.81% in the same harvest periods was observed to take the second place among the highest released volatile compounds
