It is essential to investigate nutritional values of Phoenix dactylifera fruit in dried powder form and to find out any toxicological changes during processing of this dried powder drink.Method: Dried date powder was prepared from fresh fruit by drying it and its nutritional value and toxicological studies were carried out. The acute oral toxicity study of date powder was conducted on wistar strain rats by oral route in a dose of 0.5g/kg body weight and 0.1g/kg body weight.Result: The results of biochemical analysis of dehydrated date powder exhibited that it possesses high energy value of 311 Kcal, carbohydrate 70.5%, dietary fiber 7.3%, fat content 2.1%, protein 2.6%, and mineral content 2.2%. Whereas, total sugar was found to be as 63.2% and moisture content 2.3%. The test drink showed no sign of toxicity or death during the whole observation period (fourteen days) in rats.
