Antioxydant Activity of Some Algerian Olive Oil Samples in the Eastern and Center of Algeria

This study aimed to evaluate the antioxidant activity of five Algerian olive oil samples from Chlef, Jijel, Tissemsilt, Bejaia and Tizi Ouzou regions. Thus the following results were found physicochemical caracterisation revealed that the samples are conform to standards prescribed by IOC (2013) as they are type-oleic and linoleic varies between virgin and extra virgin Chlef, Djijel and Bejaia oils are richer in carotenoids than those of Tizi Ouzou and Tissemsilt. Chlef and Tissemsilt oils are richer in phenolic compounds than other oils and have revealed very important antioxidant activity and the largest inhibitory power of peroxidation.
