Abstract
Abstract A flavored chewing gum is provided which contains a water-insoluble chalk-free gum base, a slowly or poorly extractable or poorly water-soluble sweetener in particulate form, such as the free acid form of saccharin or free cyclamic acid, and optionally, a slowly or poorly extractable or poorly water-soluble food acid in particulate form, for example, fumaric acid, dispersed in the gum base. The particulate sweetener and food acid (where present) undergo controlled release from the gum base for relatively long periods during which time the chewing gum delivers a sweet taste unaccompanied by a metallic or bitter after-taste.
