Chemical composition, sugars, minerals, amino acids, fatty acids, antinutrtional substances and organoleptic evaluation of date seeds were determined before and after roasting and compared with commercial coffee. from the obtained results, it was observed that, there were no significant differences in chemical composition of the three date seeds varieties, the Sewi date seeds have the highest value of antioxidants and they recorded least amount of anti-nutritional factors (phytate). Therefore Sewi date seeds were selected to technological application. The obtained results revealed that date seeds have high nutritional value and contain high content of total carbohydrates, fiber, protein, antioxidants, oil and low content of anti-nutritional substances.
