Abstract
The present invention pertains to a method for preparing a stable sweetening agent delivery system which comprises the steps of (A) providing the following ingredients in percentages by weight of the sweetening agent delivery system (a) at least one solid natural or artificial high intensity sweetening agent present in an amount from about 0.01% to about 50%, (b) an emulsifying agent present in an amount from about 0.5% to about 20%, and (c) polyvinyl acetate present in an amount from about 40% to about 93% and having a molecular weight range from about 2,000 to about 14,000, and (B) coating the sweetening agent with a polyvinyl acetate matrix coating and granulating the coated sweetening agent by a method which comprises the steps (a) melting and blending the polyvinyl acetate with the emulsifying agent and mixing the sweetening agent therein to form a homogeneous mixture in a heated mixing bowl containing a discharge valve in a Double Planetary Mixer, (b) transferring the mixing bowl containing the homogeneous mixture to a Direct Discharge System containing a hydraulic discharge platen, adapted to fit inside the mixing bowl, and hydraulically discharging the mixture from the mixing bowl through the discharge valve into an air and water cooled Hot Melt Granulator, (c) granulating the mixture into particles in the Hot Melt Granulator, (d) cooling and transferring the particles from the Hot Melt Granulator to an Oscillating Granulator by passing the particles through a Cyclone, and (e) granulating the particles in the Oscillating Granulator to a final desired particle size.
