The total sugars in the mesocarp of the date palm fruit is between 70 and 80%. Approximately 60% of the dry weight of the mesocarp at the Khalal and early Rutab stages of fruit development is sucrose. High-yielding varieties of date palm have fruit yield potentials of 12.0 tons/ha, equivalent to an estimated production of 7.2 tons/ha of sucrose if the fruit is harvested at the stage of maximum sucrose accumulation. The estimated sucrose production from the date palm compares very favourably with the world average of 6.6 tons/ha for canesugar and the beet sugar average of 5.6 tons/ha for Europe. The relatively high sugar content of the fruit suggests that the date palm may have an important agro-industrial future as a potential source for refined sugar.
