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 applying to the domestic dates a coating of a liquefied composition containing water and an effective amount of at least one saccharide sugar sweetening agent. The saccharide-coated domestic dates are steamed at a temperature and for a period of time which are sufficient to darken the coated domestic dates throughout to substantially the same darkness as that of imported dates. The steamed, coated domestic dates are dried to provide shelf-stable, treated 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.
