The active ingredient, such as the artificial sweetener aspartame, is blended into the encapsulating composition as, for example, by melt blend which can then be cooled to a solid and ground into particulate. The encapsulated active ingredient can then be used in a composition for ingestion by a human in the form of, for example, a chewing gum with extended shelf life and highly controlled release of the active ingredient.Field of SearchNORMALLY NONINGESTIBLE CHEWABLE MATERIAL OR PROCESS OF PREPARATIONLow-adhesive type Packaged, structurally defined, or coated Dry flake, dry granular, or dry particulate material Encapsulated, or coated triglyceridic material Triglyceridic material film former Sugar or carbohydrate containing Noncarbohydrate sweetener or composition containing same | |
