Abstract
A dry powder edible film coating composition for use in pharmaceuticals, confectionery and food, comprising a dry mixture including powdered particles of a film forming non-toxic polymer, powdered edible pigment particles, and an edible polymer plasticizer, said dry mixture being solvent free. A method of making a dry powder edible film coating composition of powdered pigment particles for use in pharmaceuticals, confectionery and food, comprising the steps of mixing a powder of a film forming polymer and powdered pigment particles in a blender to form a polymer-pigment mix, and adding the plasticizer to the blender containing the polymer-pigment mix and mixing until the combined mix is blended to form the dry powder edible film coating composition.
