  • Patent number: 5284659
    Abstract: A confectionery compressed tablet designed to dissolve in the oral cavity and containing a flavor ingredient intimately bound with a bioadhesive is disclosed. The flavor and bioadhesive composition provide a unique mouthfeel so that as the confection dissolves in the oral cavity, a coating of flavor adheres to the moist areas of the oral cavity. There is also provided a confectionery compressed tablet characterized by a single product body with discrete phases contained therein which act to provide timed release of at least one flavor ingredient sequentially. A flavor and bioadhesive mixture can be prepared with a hydrophilic delivery system providing rapid initial delivery of the flavor and unique mouthfeel or as a part of a hydrophobic delivery system providing extended periods of flavor delivery and unique mouthfeel. There is also provided a process for preparing confectionery compressed tablets containing the unique flavor delivery system and mouthfeel.
