Abstract

A method of preparing a smoke-treated tobacco material is provided, the method including the steps of: (i) subjecting a tobacco material to smoke to give a smoke-treated tobacco material with modified taste characteristics; and (ii) incorporating the smoke-treated tobacco material into a smokeless tobacco product. The invention also provides a smokeless tobacco product incorporating a smoke-treated tobacco material. The smokeless tobacco product may be, for example, a moist snuff tobacco product.

First claim

What is claimed:

1. A method of preparing a flavorful smokeless tobacco product, comprising:
(i) producing smoke from a wood material selected from oak, beech, alder, hickory, mesquite, acacia, ash, birch, pecan, walnut, almond, maple, olive, cottonwood, lilac, apple, crabapple, pear, cherry, plum, and combinations thereof,
wherein the producing comprises applying friction to the wood material;

(ii) subjecting a tobacco material to the smoke to give a smoke-treated tobacco material with modified taste characteristics; and
(iii) incorporating the smoke-treated tobacco material into a smokeless tobacco product.

2. The method of claim 1 , wherein the tobacco material comprises solid tobacco material selected from the group consisting of lamina and stems.

3. The method of claim 1 , wherein the tobacco material comprises cured tobacco material.

4. The method of claim 1 , wherein the tobacco material comprises dark air cured tobacco.

5. The method of claim 1 , further comprising curing the tobacco material, wherein the subjecting is done during the curing step.

6. The method of claim 1 , wherein the subjecting is done at a temperature around 25° C. or below.

7. The method of claim 1 , wherein the subjecting is done at a temperature around 25° C. or above.

8. The method of claim 1 , further comprising mixing the smoke-treated tobacco material with a second tobacco material prior to the incorporating step.

9. The method of claim 8 , wherein the second tobacco material is not a smoke-treated tobacco material.

10. The method of claim 1 , further comprising grinding the smoke-treated tobacco material so as to provide it in particulate form.

11. The method of claim 1 , wherein the smokeless tobacco product further comprises one or more additional components selected from the group consisting of flavorants, fillers, binders, pH adjusters, buffering agents, colorants, disintegration aids, antioxidants, humectants, and preservatives.

12. The method of claim 1 , wherein the smokeless tobacco product is in the form of moist snuff.

13. The method of claim 1 , wherein the smokeless tobacco product comprises the smoke-treated tobacco material contained within a sealed pouch.

14. The method of claim 1 , wherein the smoke-treated tobacco material has a lower concentration of benzo(a)pyrene than that present in a comparable amount of dark fire cured tobacco that has not been subjected to step (ii).

15. A method of preparing a flavorful smokeless tobacco product, comprising:
(i) subjecting a tobacco material to smoke to give a smoke-treated tobacco material with modified taste characteristics,
wherein the subjecting comprises atomizing or vaporizing liquid smoke; and

(ii) incorporating the smoke-treated tobacco material into a smokeless tobacco product.

16. The method of claim 15 , wherein the tobacco material comprises dark air cured tobacco.

17. A method of preparing a flavorful smokeless tobacco product, comprising:
(i) subjecting a tobacco material to smoke to give a smoke-treated tobacco material with modified taste characteristics;
(ii) fermenting the smoke-treated tobacco material, wherein the subjecting is done during the fermenting step; and
(iii) incorporating the fermented smoke-treated tobacco material into a smokeless tobacco product.

18. The method of claim 17 , wherein the tobacco material comprises dark air cured tobacco.
