Abstract
An oral pouch product includes an immobilized flavorant comprising one or more flavorants and an immobilizing matrix disposed around the flavorants and containing slightly water soluble β-cyclodextrin, gum Arabic, and/or a starch. In addition, a method for preparing the oral pouch product is described, which includes (a) preparing an immobilized flavorant by mixing a flavorant and one or more matrix-forming materials comprising slightly water soluble β-cyclodextrin, gum Arabic, and/or a starch in a solvent to form a mixture; optionally heating the mixture; and drying the mixture to form a dried immobilized flavorant; and (b) incorporating the dried immobilized flavorant into an oral pouch product.
Claims26
An oral pouch product designed for insertion in the oral cavity for the sustained release of flavorant, comprising:
- a porous pouch wrapper;
- an inner filling material in particulate form, comprising an immobilized flavorant composition, comprising:
- one or more flavorants;
- and
- an immobilizing matrix disposed around the one or more flavorants and comprising slightly water soluble underivatized β-cyclodextrin, wherein said one or more flavorants is capable of being released from said immobilizing matrix over an extended period of time when said oral pouch product is in contact with saliva within the mouth thereby yielding the gradual delivery of said one or more flavorants.
