Abstract

The physical properties, chemical composition, mineral constituents and amino acid profile of five Sudanese date fruit cultivars; Gondaila, Pittamuda, Barakawi, Wadlegai and Wadkhateib were studied. The main physical testing approaches revealed that Gondaila, Pittamuda and Barakawi possessed larger fruit volume, surface area and weight than Wadlegai and Wadkhateib cultivars. Further, the degree of fruits sphericity obtained showed that Wadlegai and Wadkhateib were more round in shape than the other three cultivars. The chemical analysis results revealed that the moisture content Gondaila, Pittamuda and Barakawi was lower than in the two Mishrigi cultivars; Wadlegai and Wadkhateib. The fruits contained high levels of total sugars; they also contained considerable amounts of fiber and tannins. However, they possessed low amounts of proteins and fats. The studied date cultivars also possessed a number of essential amino acids and minerals.

Keywords: Palm dates, cultivars, physio-chemical, nutritional quality.
