Abstract

The present invention is directed to an encapsulated material for use in chewable compositions. The encapsulated material is formed by blending an encapsulating solution with essential oils or other hydrophobic or amphipathic compounds flavoring solution to form a homogenous coating solution. The homogenous coating solution is contacted with a substrate to provide a flavored composition.

Claims

1. A chewing tobacco and/or snuff composition comprising tobacco encapsulated with an encapsulating material, wherein the encapsulating material is a homogenous blend of an encapsulating solution and essential oils or other hydrophobic or amphipathic compounds,

wherein the encapsulating solution comprises a blend of a hydroxyl containing compound and a dextran or dextran derivative.

2. A chewing tobacco and/or snuff composition according to claim 1 wherein the encapsulating solution comprises a blend of a hydroxyl containing compounds effective for use in spray coatings and a dextran or dextran derivative.

3. A chewing tobacco and/or snuff composition according to claim 1 wherein the hydroxyl containing compound is selected from the group consisting of hydroxy propyl methylcellulose, sucrose, gelatin, modified, unaltered starched, and mixtures thereof.

4. A chewing tobacco and/or snuff composition according to claim 3 wherein the hydroxyl containing compound is sucrose.

5. A chewing tobacco and/or snuff composition according to claim 1 wherein the dextran derivative is maltodextran.

6. A chewing tobacco and/or snuff composition according to claim 1 wherein the encapsulating solution has a solids content of 60 weight percent or less.

7. A chewing tobacco and/or snuff composition according to claim 1 wherein the encapsulating solution has at least about 5 weight percent hydroxyl containing compound and at least about 5 weight percent dextran or dextran derivative.

8. A chewing tobacco and/or snuff composition according to claim 1 wherein the essential oils or other hydrophobic or amphipathic compounds are blended with an emulsifying agent.

9. A chewing tobacco and/or snuff composition according to claim 8 wherein the essential oil is a mint oil from any species of the genus Mentha.

10. A chewing tobacco and/or snuff composition according to claim 9 wherein the essential oil is spearmint.

11. A chewing tobacco and/or snuff composition according to claim 9 wherein the essential oil is peppermint.
