Abstract
Objective: Phoenix dactylifera fruit widely used in Muslim countries.They have religious attachment to it and also it had many health benefits. 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. No group of animal showed any unusual change in behavior or in locomotors activity. The macroscopic studies of vital organs i.e. heart, liver, spleen, lungs and kidneys exhibited that they were normal.Conclusion: As a result of these studies it can be concluded that from processing of fresh fruit to dried powder along with its nutritional and toxicological studies no hazardous material like toxins were produced. So it can be used safely.Bangladesh Journal of Medical Science Vol.17(2) 2018 p.263-269
Highlights
It is well reported that a human body need a variety of essential vitamins and minerals to carry out important roles to keep it well
In the light of these facts a drink was formulated from P. dactylifera fruit to utilize it in our daily diet to provide more essential nutrients to body as it can perform its daily activities without getting tired or stressed
The results of nutritional analysis indicate that the formulated date powder having high energy value of 311 Kcal, carbohydrate 70.5%, dietary fibre 7.3%, fat content 2.1%, protein 2.6%, and mineral content 2.2%
Summary
It is well reported that a human body need a variety of essential vitamins and minerals to carry out important roles to keep it well. After the completion of dehydration process, the chopped dates were converted into solid mass having a brown color At this stage 15-16 Kg dried solid mass was ground in a Pin Grinder to obtain 100-120 mesh size powder, this powder was further dried in a Fluidized Bed Dryer at 50oC for 30-35 minutes where 4-5 % moisture contents were removed. 40 ml of 10% clarified sample solutions were taken in 50 ml conical flask and 05 ml of concentrated Hydrochloric acid was added and the content was incubated at 55-60 ̊C for exactly 10 minutes. The results of biochemical analysis of dehydrated date powder having 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%.
