The present invention is a chewing gum base composition which includes an elastomer and a resin prepared in the absence of rosin esters and terpene components which includes an elastomer component raised to a compatibilization temperature for addition of a compatibilization component. The composition includes a high melting point wax compatibilization component added under low shear mixing conditions at a temperature sufficient to masticate the elastomer for forming a substantially homogeneous mass with the resin component. The compatibilization component is capable of effectuating dissociation of the elastomer under the conditions of temperature and mixing for forming the substantially homogeneous mass. Finally, a resin component is added also under low shear mixing conditions and mildly elevated temperatures until a substantially homogenous gum base mass is formed.

Chewing gum composition and method of making same

An ingestible gel confectionary delivery system which includes a pectin gel component in an amount sufficient to form a gel confectionary unit, and an edible insoluble solid in an amount sufficient to strengthen the internal pectin gel network and to bind internal moisture sufficiently to enhance mold removal capabilities. Preferably the delivery system also includes a further active ingredient such as a drug, medicament, or nutritional supplement. The product and method of the present invention also includes a composition in which the gel delivery system can be molded directly in the receptacle which is used to dispense the confectionary unit to the consumer. This significantly enhances the manufacture of product prepared in accordance with the invention.

Pectin delivery system

A drug delivery system comprising a core material comprising a drug, and a hydrophobic matrix coating the core. The coating delays hydration of the drug and masks the taste of the drug. The coating comprises an emulsifier, an edible fatty acid or wax and a glyceride. The delivery system can be incorporated into various food products, pharmaceutical preparations and proprietary products.

Novel drug delivery system for expectorants

Novel drug delivery system for mineral supplements

The present invention is method and composition for protecting an active ingredient and providing controlled release therefor, especially in a chewing gum composition, which includes a high molecular weight polyvinyl acetate blended with a hydrophobic plasticizer which forms a film with the high molecular weight polyvinyl acetate in the absence of an added solvent therefor. 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.

Encapsulation composition for use with chewing gum and edible products

Novel drug delivery system for antitussives

The present invention comprises a chewing gum composition having extended sweetness release including a chewing gum base, an extended release encapsulated sweetening agent in a coating material including a hydrophobic polymer and a hydrophobic plasticizer. The chewing gum composition has sweeteness release of up to 30 minutes during mastication.
