Delayed release in chewing gum of an active ingredient, such as a sweetener or a food acid, is provided by encapsulating solid particles of the active ingredient in a polydiorganosiloxane. The resulting polydiorganosiloxane-encapsulated active ingredient includes a continuous phase with the polydiorganosiloxane and a disperse phase with the solid particles of the active ingredient. When incorporated into a chewing gum, the polydiorganosiloxane-encapsulated active ingredient provides a more delayed release than conventional poly(vinyl acetate)-encapsulated active ingredients.
