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 encapsulated materials.

2. A chewing tobacco and/or snuff composition according to claim 1 wherein the encapsulated material is formed by blending an encapsulating solution with an essential oils or other hydrophobic or amphipathic compounds.

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

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

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

6. A chewing tobacco and/or snuff composition according to claim 3 wherein the dextran derivative is maltodextran.

7. A chewing tobacco and/or snuff composition according to claim 3 wherein the encapsulating solution has a solids content of 60 weight percent or less.

8. A chewing tobacco and/or snuff composition according to claim 3 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.

9. A chewing tobacco and/or snuff composition according to claim 2 wherein the essential oils or other hydrophobic or amphipathic compounds are blended with an emulsifying agent.

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

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

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

13. A process for preparing a flavored chewing tobacco and/or snuff composition comprising contacting tobacco with a homogenous coating solution, wherein the homogenous coating solution comprises encapsulated materials.

14. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 13 wherein the encapsulating solution comprises a blend of a hydroxyl containing compounds effective for use in spray coatings and a dextran or dextran derivative.

15. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 14 wherein the hydroxyl containing compound is selected from the group consisting of hydroxy propyl methylcellulose, sucrose, gelatin, modified, unaltered starched, and mixtures thereof.

16. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 15 wherein the hydroxyl containing compound is sucrose.

17. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 14 wherein the dextran derivative is maltodextran.

18. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 14 wherein the encapsulating solution has a solids content of 60 weight percent or less.

19. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 14 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.

20. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 13 wherein the essential oils or other hydrophobic or amphipathic compounds are blended with an emulsifying agent.

21. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 20 wherein the essential oil is a mint oil from any species of the genus Mentha.

22. A process for preparing a flavored chewing tobacco tobacco and/or snuff composition according to claim 21 wherein the essential oil is spearmint.

23. A process for preparing a flavored chewing tobacco and/or snuff composition according to claim 21 wherein the essential oil is peppermint.

24. A substrate comprising encapsulated materials, wherein the encapsulated material is formed by blending an encapsulating solution with a essential oils or other hydrophobic or amphipathic compounds.

25. A substrate according to claim 24 wherein the encapsulating solution comprises a blend of a hydroxyl containing compounds effective for use in spray coatings and a dextran or dextran derivative.

26. A substrate according to claim 25 wherein the hydroxyl containing compound is selected from the group consisting of hydroxy propyl methylcellulose, sucrose, gelatin, modified, unaltered starched, and mixtures thereof.

27. A substrate according to claim 26 wherein the hydroxyl containing compound is sucrose.

28. A substrate according to claim 25 wherein the dextran derivative is maltodextran.
