Abstract

This study aimed to determine some physical and chemical properties of some olive oil, collected from the local market in Libya. Samples were collected from Awinya- Aljabal Algharbi, Brack Alshati, Sebha, and Ubari. There were no significant differences in physical properties of all examined samples. However The chemical properties were as following; acidity was between (0.5890±0.024-%16.552±0.232). The lowest value of peroxide was recorded in Awinya sample 5.50±0.231 mEq O2/Kg, and the highest value was in stored olive oil sample 54.00±0.213 mEq O2/Kg. Iodine value was between (65.50±0.132 in stored sample and 93.65±0.007 in Brack sample). Saponification values were between (188.50±0.111 and 252.55±0.152) Generally the results of chemicals analysis were within Libyan standards.
