Shaker M. Arafat, Amany MM. Basuny, Mohamed E. Elsayed, Hanaa M. Soliman

The aim of this study examined the effects of three different areas (Siwie, Ben suef and k64 Cairo Alexandria desert road) that have important differences in climatic and pedologic conditions on the quality indices (free fatty acid, peroxide value and K232, K268), oxidative stability, total phenolic compounds, o-diphenol, fatty acids and sterols composition of extracted oils from three common cultivars (Koronakii, Coratina and Maraqi) growing in Egypt. The obtained results were compared with Standard of International Olive Council.The research results showedthat the quality indices, oxidative stability,fatty acids and sterols composition of the oils were largely influenced by the origin zone, i.e.,by the climatic and pedologic factors of the production environment.
