| Abstract | ||||
| Picual olive fruits were soaked in hot water, sun-dried irradiated at 1.5KGy and the olive oil was obtained by pressing . Physical and chemical properties , stability, fatty acids compostion and unsaponifiable mater (USM) constituents were determined in all samples undertaken. The results indicated that, sun - drying treatment nriarkdiy increased the peroxide value of olive oil, while all treatments under investigation had no real effects on other oil properties and fattry acid composition. Soaking tratment caused no changes, while sun - drying and irradiation induced a remarkable changes in the USM components olive oil.. Squalene increased and B-sitosterol decreased by irradiation, while the reverse trend occurred by sun- drying treatment . In addition, olive oil stability increased by irradition and decreased by sun - drying | ||||
