ABSTRACT:
A method for the production of an anhydrous powdered dextrose containing large amounts of anhydrous crystals of .beta.-form dextrose, characterized by concentrating aqueous solutions of dextrose, or aqueous solutions containing dextrose up to a sugar concentration of 90 to 98%, adding anhydrous crystals of .beta.-dextrose or powdered dextrose containing large amounts of anhydrous .beta.-dextrose as seed crystals to this concentrate at temperatures above 60.degree. C., maintaining the temperature above 60.degree. C., and while stirring gently, eliminating the free water by vacuum dehydration from the time of formation of microcrystals by adequately reducing the pressure.
