Abstract
In this study, fruits of date (Phoenix dactylifera L.) varieties were analyzed to assess their nutritional characteristics. Mineral profile analysis of twenty-one date varieties grown in Pakistan was performed. The results of mineral profile analysis proved that dates were a good source of minerals like potassium, calcium, iron and magnesium, but were deficient in sodium content and hence are very suitable fruit for hypertensive people. Sugar profile analysis showed that the maximum glucose content was recorded in Zaidy (44.44%) and fructose content in Karblain (33.21%) and the maximum sucrose percentage was found in Hillavi (6.99%). Vitamin (B-1, B-2, and B-3) analyses revealed that vitamin B-1 was not present in detectable amount in the date varieties. The highest concentration of vitamin B-2 was detected in Khopra (0.031 mg per 100g), while the highest concentration of vitamin B-3 was verified in Zaidy (2.73 mg per 100g). The range of the total phenolic contents ranged from 142.52 +/- 0.64 to 298.02 +/- 0.95 mg gallic acid equivalent per 100 g on fresh fruit weight basis. All date varieties proved to be a good source of phenolic compounds, therefore, they possess high antioxidant capacity. It was concluded that Dhakki, Hillavi and Aseel Sindh varieties might suit well for diet because of their good nutritional properties.
