Determination Of Bitterness Index (K225) And Total Fenol Content Of Olive Oils Obtained With Different Regions, Varieties And Processing Systems

Öz:
In this work the effect of differentgrowing areas on olive (Ayvalık, Memecik, Gemlik, Beylik, Edincik Su, Girit,Kilis Yağlık, Sarı Ulak, Tavşan Yüreği, Topak Aşı) oil bitterness index (K225)were studied at the South Marmara, South and North Aegean, West and EastMediterranean  Regions at two, two and ahalf (2.5), and three phase extraction system, during 2014/2015 crop season. Atotal of 41 virgin olive oils samples were collected from these Regions. Totalphenol content and bitternes index (K225) were analyzed in theresearch. A Solid-Phase Extraction procedure were carried out for extraction ofthe bitter compounds. The results of total phenol content and K225 valuesshowed that the Beylik olive oil was determined with the highest total phenolconent and bitterness index (K225) with 330.26 mg CAE kg-1 oil  and 1.21 at 2.5 phaseextraction system from Manavgatat the West Mediterranean Region, respectively. After the Beylik  variety, the highest total phenol content wasdetermined Ayvalık and Edincik Su olive oil with 291.03 and 270.62 mg CAE kg-1 oil, respectively. TheMemecik and Ayvalık olive oil bitterness index (K225) was determined 0.86 and 0.85 at two phase extractionsystem from Muğla and Burhaniye at the Southand North Aegean, respectively.

Farklı Bölge, Çeşit Ve Üretim Sistemleri İle Elde Edilen Zeytinyağlarının Acılık İndekslerinin Ve Toplam Fenol Değerlerinin Belirlenmesi

Öz:
Bu çalışmada, zeytinyağlarının acılık indeksi (K225) değeri üzerine yetiştirilme bölgelerinin etkisi incelenmiştir.  Bu amaçla, 2014/2015 hasat yılında Güney Marmara, Güney ve Kuzey Ege ile Batı ve Doğu Akdeniz Bölgelerinde yetişen zeytinlerden (Ayvalık, Memecik, Gemlik, Beylik, Edincik Su, Girit, Kilis Yağlık, Sarı Ulak, Tavşan Yüreği, Topak Aşı) iki, iki buçuk ve üç fazlı ekstraksiyon sistemi elde edilen, toplam 41 zeytinyağı örneği toplanmıştır. Çalışmafda toplam fenol içeriği ve acılık indeksi analizleri yapılmıştır. Acılık bileşenlerinin ekstraksiyonu için katı faz ekstraksiyon sistemi uygulanmıştır. Toplam fenol içeriği ve acılık indeksi (K225) değeri sonuçlarına bakıldığında, Batı Akdeniz Bölgesindeki Manavgat ilçesinden iki buçuk faz ekstraksiyon sistemi ile elde edilen Beylik zeytinyağının 330.26 mg CAE kg-1 yağ ile en yüksek toplam fenol ve 1.21 ile en yüksek acılık indeksi değerini gösterdiği tespit edilmiştir. Beylik çeşidinden sonra, en yüksek toplam fenol içeriği 291.03 mg CAE kg-1 yağ ile Ayvalık ve 270.62 mg CAE kg-1 yağ ile Edincik Su zeytinyağında tespit edilmiştir. İki fazlı ekstraksiyon sistemin ile Güney Ege’de Muğla’dan elde edilen Memecik ve Kuzey Ege'de Burhaniye’den elde edilen Ayvalık zeytinyağlarının acılık indeksleri değerleri sırasıyla 0.86 ve 0.85 olarak tespit edilmiştir.
