Abstract

The chemical analysis of fruits from twelve varieties of date palm (Phoenix dactylifera) which are widely consumed in the United Arab Emirates was undertaken, and figures showed that glucose and fructose increase rapidly with maturation from Kimri through Khalal and Rutab to Tamr. Total sugars may represent over 50% of the fresh weight at Tamr, and these values, together with low moisture contents, encourage resistance to fungal spoilage after harvest. Minerals accumulated in the fruits as well, and the date could be an important source of potassium for regular consumers.
