Abstract
Process for treating relatively light-colored dates grown domestically to impart thereto the relatively darker appearance, the flavor, the soft-chewy texture and the shelf-stability of imported dates grown in the Middle East region. The process involves steaming domestic dates at a temperature of at least 175.degree. F. and for a period of time which is sufficient to darken the domestic dates throughout to substantially the same darkness as that of imparted dates. The steamed domestic dates are then dried to provide shelf-stable, treated dates. At no time before or during the process is a liquefied composition containing water and an effective amount of at least one saccharide sugar sweetening agent applied to or contacted with the domestic dates. The size and shape of the shelf-stable, treated dates are substantially the same as the size and shape of the starting domestic dates. Domestic dates are generally of the sucrose-type dates, whereas the imported dates are generally of the inverted-sugar type dates.
