Abstract
Abstract Controlled release flavor compositions are disclosed which comprise flavor particles having an outer coating of a physiologically inert, water-softenable and swellable material. The flavor particles are formed from an intimate dispersion of flavor acetal or ketal in physiologically inert polymeric binders. The flavor acetals or ketals comprise the reaction product of a flavor aldehyde or flavor ketone and a polyhydroxy compound such as glycerine. The release of flavor in these compositions has three levels of control. These are: (1) hydrolysis of the flavor acetal or ketal; (2) diffusion through the polymeric matrix; and, (3) diffusion through the outer coating surrounding the flavor particle. Controlled release flavor compositions, as described herein, are particularly useful in chewing gums.
