The study was carried out to investigate the physicochemical analysis of olive oil from cooperatives for olive growers and allowed us to identify and classify the oils. The samples which were studied collected during the period when olives are usually harvested for oil production (November 2011), from the North of Morocco are specific to the region of Ouazzane in Loukkos were examined for physical and chemical properties (acidity, pH, peroxide values, saponification number, iodine value, ultraviolet spectrophotometric analysis (k232 and k270), refractive index) and total phenol content. Total phenol contents expressed as gallic acid of olive oils values ranged from (124 to 313 mg/kg). All olive oil samples were compared with International Olive Oil Council (IOOC), were not exceed the limits and exhibited remarkable physicochemical properties and could be useful as edible oils and industrial applications.
