The quality of extra virgin olive oils (EVOO) from whole fruits and fruit flesh of Kaissy olive (Olea europaea) cultivar was investigated in this study. Acid value (AV), peroxide value (PV), iodine value (IV), specification number (SV), Thiobarbituric acid (TBA) value, phenol content, refractive index (RI) and viscosity were measured after 0, 6 and 12 months of storage. The physicochemical properties of oil extracted from whole fruit and fruit flesh samples of olive were: AV (0.32 and 0.40%), PV (4.79 and 6.13%), TBA (0.056 and 0.052 mg MDA kg-1 oil), IV (84.41 and 83.87 g-1 oil), SV (195.48 and 187.56 mg KOH g-1 oil), total phenolic (339.52 and 226.68 mg gallic acid kg-1 oil), RI (1.4669 and 1.4668) and viscosity (129.33 and 130.00 mPa s-1) respectively. The results demonstrated that the AV, PV, RI and viscosity values significantly (p<0.05) increased, while TBA value and total phenolic content significantly (p<0.05) decreased during storage.
