The objective of this study was to produce healthy cocoa butter substitutes from extra virgin olive oil rich in omega-9 and polyphenols by blending process with palm oil avoiding hydrogenation and esterification processes. Oil blends, formulated by binary blends of palm oil and extra virgin olive oil at different ratios (90:10, 80:20 and 70:30) compared with commercial cocoa butter. The physicochemical properties (refractive index, melting and slip point, color index, acidity, peroxide value, iodine number and induction period by Rancimat method) have been determined for palm and olive oils and the produced cocoa butter substitute. Also, fatty acid composition was identified by gas liquid chromatography and solid fat content of the produced cocoa butter substitute w as measured by Nuclear Magnetic Resonance (NMR) and total polyphenols of oils and produced cocoa butter substitute w ere determined. The results indicated that all the values of melting and slip point were about the human body temperature (37 ° C), also results show a high content of cocoa butter produced from oleic acid, as well as phenolic compounds, and this leads to an increase in oxidative stability.
