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.

Gradual release structures for the release of active agents in chewing gum and a process for making such structures are provided. The gradual release structures are formed by extrusion techniques and comprise an active agent and a wall material.

Gradual release structures for chewing gum

A method of manufacturing a chewing gum is disclosed wherein a first mixing step mixing an amount of either a low fat gum base or a non-tack gum base having a premix temperature of about 200.degree.-240.degree. F., an amount of HFO gum base having a temperature of about 60.degree.-80.degree. F. and a portion of the bulking agents are mixed until homogenous. In a final mixing step, the resulting gum base blend is mixed with an amount of flavor and the remaining portion of the bulking agent.

Gradual release structures for the release of active agents in chewing gum and a process for making such structures are provided. The gradual release structures are formed by extrusion techniques through slot dies and comprise an active agent and a wall material.

An improved method of encapsulating an active ingredient for use in chewing gum involves extruding a blend of polyvinyl acetate, an active ingredient and salt. The invention also includes an encapsulated active ingredient prepared according to the improved method, and a chewing gum which contains the encapsulated active ingredient of the invention.

Use of salt to improve extrusion encapsulation of chewing gum ingredients

A method of sparging off-notes from mint flavors using nitrogen is provided. The method comprises passing nitrogen through a mint flavor for a sufficient time at sufficient pressure until off-notes are eliminated. A method of preparing oral compositions, including chewing gum, comprising nitrogen sparged mint flavor is also provided.
