Gradual release structures for the release of active agents in chewing gum and a process for making such structures are provided. The gradual release structures are formed by meltspinning techniques and comprise an active agent and a wall material. The invention provides for a chewing gum which comprises: a gum base; a water soluble bulk portion; and, a gradual release structure formed by melt spinning a mixture of active agent and spinnable polymeric wall material, having more than zero but less than 55 percent by weight active agent, into a fiber, and cutting the fiber. <IMAGE> |
