Abstract: An edible dry-powder formulation of a film coating for pharmaceuticals and confectioneries using gum acacia as a low-cost film former is provided. A cellulosic polymer such as hydroxypropyl methylcellulose is used in addition to the gum acacia. A plasticizer such as propylene glycol is also added. The resulting formulation is a dry, free flowing powder that can be put into solution and applied to a tablet or other substrate without an extended waiting period. The resulting film coating is clear, shiny, durable and extremely economical. Because the formulation is a dry powder, it has along shelf life and low shipping costs.

Abstract: The invention is a process for recrystallizing sugar. The invention involves admixing a first quantity of a powdered sugar and a second quantity of an adjuvant, such as an invert sugar, to provide a sugar blend. The sugar blend has up to about 3 percent moisture. The invention then involves mixing the sugar blend with a high shear extruding means at a temperature between about 220.degree. F. and about 300.degree. F. with a residence time in the extruding means of between about 0.5 second and about 12 seconds. The invention includes the product of a combined phase recrystallized sugar.
