Based on the sugar content dates are generally classified into two categories [1,2]:
Cane sugar varieties and invert sugar varieties. The sugar content in Cane Sugar Varieties is mainly sucrose while the sugar content in Invert Sugar Varieties is free Glucose and free Fructose. In most varieties, the sugar content is almost entirely of the inverted form (glucose or fructose), but a few varieties mainly contain cane sugar (sucrose).
Based on moisture content ripened dates are generally classified into three categories:
Fresh: with 18% to 35% moisture.
Semi Dried: with 15% to 18% moisture.
Dried: with less than 15% moisture.
