Abstract

The invention provides a tobacco composition for use in a smoking article or a smokeless tobacco composition that comprises an extract derived from a component of a plant of the Nicotiana species. The invention also provides smoking articles and smokeless tobacco compositions that include the extracts described herein, and methods for preparing extracts derived from a component of a plant of the Nicotiana species for addition to a tobacco composition.

Claims

1. A flavorful tobacco composition for use in a tobacco product in the form of an extract derived from tobacco material comprising at least 90 percent by dry weight of stalk, root, or stalk and root of a plant of the Nicotiana species, wherein the extract comprises at least one compound selected from vanillin and syringaldehyde.

2. The tobacco composition of claim 1, wherein the extract is in powder form.

3. The tobacco composition of claim 1, wherein the extract is contained within a casing formulation or a top dressing formulation adapted for application to a tobacco material.

4. The tobacco composition of claim 1, wherein the extract is derived from the stalk of a plant of the Nicotiana species.

5. The tobacco composition of claim 1, wherein the extract is derived from the root of a plant of the Nicotiana species.

6. The tobacco composition of claim 1, wherein the extract comprises both material derived from the stalk and material derived from the root of a plant of the Nicotiana species.

7. The tobacco composition of claim 1, wherein the extract further comprises one or more compounds selected from the group consisting of C2 pyrazines, C3 pyrazines, acetic acid, dihydro-2-methyl-3-furanone, furanethanolacetate, furanmethanol, maltol, 3-hydroxypyridine, 5-methylfurfural, hexanal, pentylfuran, nonanal, decanal, menthol, 3-methylpentanoic acid, 2-hydroxy-3-methyl-2-cyclopenten-1-one, 3-hydroxypyridine, and 2,6-dimethoxyphenol.

8. The tobacco composition of claim 1, wherein the extract is in liquid form.

9. The tobacco composition of claim 1, wherein the extract is derived from a flue-cured stalk of a plant of the Nicotiana species.

10. The tobacco composition of claim 1, wherein the extract comprises syringaldehyde.

11. A tobacco product comprising a flavorful tobacco composition in the form of an extract derived from tobacco material comprising at least 90% by dry weight of stalk, root, or stalk and root of a plant of the Nicotiana species, wherein the extract comprises at least one compound selected from vanillin and syringaldehyde.

12. The tobacco product of claim 11, further comprising a tobacco material or a non-tobacco plant material as a carrier for the extract.

13. The tobacco product of claim 11, wherein the tobacco product is in the form of a smokeless tobacco composition.

14. The tobacco product of claim 13, wherein the form of the smokeless tobacco composition is selected from the group consisting of moist snuff, dry snuff, chewing tobacco, tobacco-containing gums, and dissolvable or meltable tobacco products.

15. The tobacco product of claim 11, wherein the tobacco product is in the form of a smoking article.

16. The tobacco product of claim 15, wherein the smoking article comprises a casing formulation or a top dressing comprising the extract.

17. The tobacco product of claim 11, wherein the tobacco product is in the form of an aerosol-generating device configured for non-combustion of plant material.

18. The tobacco product of claim 11, wherein the extract comprises material derived from the stalk of a plant of the Nicotiana species.

19. The tobacco product of claim 11, wherein the extract comprises material derived from the root of a plant of the Nicotiana species.

20. The tobacco product of claim 11, wherein the extract comprises both material derived from the stalk and material derived from the root of a plant of the Nicotiana species.

21. The tobacco product of claim 11, wherein the extract further comprises one or more compounds selected from the group consisting of C2 pyrazines, C3 pyrazines, acetic acid, dihydro-2-methyl-3-furanone, furanethanolacetate, furanmethanol, maltol, 3-hydroxypyridine, 5-methylfurfural, hexanal, pentylfuran, nonanal, decanal, menthol, 3-methylpentanoic acid, 2-hydroxy-3-methyl-2-cyclopenten-1-one, 3-hydroxypyridine, and 2,6-dimethoxyphenol.

22. The tobacco product of claim 11, wherein the extract comprises syringaldehyde.
