Abstract
Date seeds are consider the most locally available agricultural waste produced annually in large quantities in Egypt. Therefore, this investigation was carried out to study the possibility of using date seeds of three verities of palm date namely Siwy, Aglany and Amhat, for preparation a coffee caffeine-free drink, antimicrobial agent in some foods and cacao replacer in cake.
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. Results showed also that date seeds were acceptable as a coffee replacer (25% roasted date seeds) as evaluated organoleptically comparing with commercial coffee. Also, bakery product fortified with date seeds powder was prepared and the product had good sensory properties and high nutritive value.
