摘要：The objective of the study was to determine the composition, quality parameters and oxidative stability of virgin olive oils from Ak Delice wild olives (Olea Europaea L. subsp. Oleaster) grown in Turkey. For this purpose, Ak Delice wild olives were harvested from Edremit, and processed to oil in an olive oil mill equipped with a pressure system. Olive oil samples were evaluated for their quality and oxidative stability besides fatty acid, triacyglycerol and sterol composition. Results have shown that free acidity, peroxide index, K 232 , K 270 , and .K values fell within the limits established for extra virgin olive oil. Chlorophyll and carotenoid contents were 7.06 mg/kg and 5.70 mg/kg respectively. The oil samples presented high oxidative stability (14.6 h, 120°C). Oleic (73.97%), palmitic (11.48%), linoleic (9.25%) were the main fatty acids while OOO (44.85%), OOP (23.21%), OOL (13.59%) and PLO (6.16%) were the major triglycerides. Total sterol content was 2069 mg/kg and β-sitosterol (81.87%), .-5-avenasterol (9.57%) and campesterol (3.32%) were the main sterols.
