Abstract
Abstract A dry, granulated, free-flowing product containing a mixture of fructose and glucose, e.g. invert sugar, is prepared by first combining a fructose and glucose solution having a high dry solids content with an essentially dry, crystalline mass comprising a mixture of fructose and glucose. The admixture of solution and crystalline mass are then agitated in a relatively dry atmosphere, i.e., less than about 30 percent relative humidity, at a temperature from about 20*C to about 50*C to form the dry, granulated, free-flowing product.
