EGE BÖLGESİ ZEYTİNYAĞLARINDA ALTI KARBONLU UÇUCU AROMA BİLEŞENLERİNİN BELİRLENMESİ

Abstract

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 boşluğu-katı faz mikroekstraksiyon (HS-SPME) yöntemi ile yağlardan uçucu aroma bileşenleri ekstrakte edilerek gaz kromatografi-kütle spektrometre (GC-MS) cihazı ile bileşenlerin kalitatif ve kantitatif analizi yapılmıştır. Altı karbonlu bileşenlerin zeytinyağı kalitesi ile ilişkili olmasından dolayı bu bileşenlerin belirlenmesi üzerinde durulmuştur. E-2-hekzenal ve hekzanal, yağ örneklerinde en fazla oranda tespit edilen bileşenlerdir. 2007-2008 ve 2008-2009 hasat döneminde E-2-hekzenal sırası ile % 13.05-67.15 ve % 23.03-52.44 aralığında belirlenmiştir.  Bu bileşeni hekzanal izlemiş, oranı ise hasat dönemlerine göre sırasıyla % 6.70-39.34 ve % 11.23-59.81 aralığında tespit edilmiştir.
