economic value and intensive olive cultivation to represent each region
of Turkey. In this context, a total of 39 olive samples, from Gemlik,
Ayvalık, Memecik, Kilis Yağlık and Nizip Yağlık olive varieties, were

FIGURE 1 Provinces where olive samples were collected
Olive oils were obtained from 10 kg olive fruits with the Abencor system
(MC2 Ingenieria y Sistemas, Sevilla, Spain). Olive samples were washed
after being separated from their leaves and crushed in a crusher. It was
subjected to mixing (malaxation) at 25°C for 30 minutes. After
malaxation, a centrifuge was used to separate the oil from the olive
paste. The obtained olive oils were stored under controlled conditions
in amber colored bottles at +4°C until the analyses were done after
filtering.
