ABSTRACT:
An improved method of combining active ingredients with polyvinyl acetate for use in chewing gum results in significantly less degradation of the active ingredients. After the polyvinyl acetate and one or more active ingredients have been mixed together in an extruder, the mixture is extruded through a die to form a sheet-like extrudate. The sheet like extrudate is then cooled using a series of three chilled compression rolls. The extrudate is pinched between adjacent chilled compression rolls and both surfaces of the extrudate maintain contact with at least one of the chilled compression rolls for a period of time. The extrudate is thereby cooled swiftly and thoroughly, resulting in reduced degradation of the active ingredients.
