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.
