A method for producing a coated chewing gum with a controlled release of an active agent, as well as the chewing gum so produced, is obtained by physically modifying an active agent's properties by coating and drying. An active agent is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated active agent is then co-dried and particle sized to produce a release-modified active agent. When incorporated into a chewing gum coating, these particles release into the mouth but mask bitter and other off-tastes in the mouth, and are readily ingested.
A method of producing a coated chewing gum product containing a physically-modified active agent in order to modify the release of the active agent in the mouth of an individual comprising the steps of:
The method of claim 2 wherein the active agent is mixed with a polymer as the encapsulating agent and the resulting mixture is extruded into fine fibers in such a way as to encapsulate the active agent in order to modify the release of the active agent in the chewing gum coating.
A method of producing a coated chewing gum product containing a physically-modified active agent in order to modify the release of the active agent comprising the steps of:
A method of producing a coated chewing gum product containing a physically-modified active agent in order to delay the release of the active agent in the mouth of an individual comprising the steps of:
