    Abstract:
    The physical and chemical properties of the date (Phoenix dactylifera L.) fruit seeds from seven date samples (Soukari, Soulag, Barhi, Khulas, Rozaiz, Soughi and Monaif) were evaluated. Energy values of dried and ground seeds were found between 4340 kcal/kg (Barhi cv) and 4795 kcal/kg (Rozaiz cv). Also, while crude oil content of seeds were established between 4.68% (Khulas cv) and 7.96% (Monaif cv), crude protein contents were found at the levels between 3.71% (Soulag cv) and 5.47% (Barhi cv). The antioxidant activity of seeds obtained from different date fruits changed between 78.03 (mg/ml) (Monaif cv) and 79.94 (mg/ml) (Barhi cv). In addition, the total phenol contents of seeds were found between 1.98 mg gallic acid equivalents (GAE)/100 g (Barhi cv) and 4.65 mg GAE/100 g (Soughi cv). The most abundant fatty acids of the date seed oils were oleic, lauric, myristic, palmitic and stearic acids. Ca, Mg, K and P contents of date seeds were found at the high concentrations.
