Abstract

The present disclosure provides protein-enriched, tobacco-containing products, suitable for use as oral formulations. Products of the present disclosure typically include at least one tobacco material (e.g., a particulate tobacco material or a tobacco-derived extract), at least one protein-enriched material (e.g., a tobacco-derived protein-enriched material), and at least one sugar alcohol.

First claim

What is claimed is:

1. A protein-enriched smokeless tobacco product comprising:
a tobacco material;
a protein-enriched, tobacco-derived material in an amount of at least about 2 percent by dry weight; and
one or more sugar alcohols in an amount of at least about 10 percent by dry weight,
wherein the protein-enriched, tobacco-derived material comprises at least about 60 percent tobacco-derived protein by dry weight, wherein the product is chewable, and wherein the product is a single layer product comprising a mixture of the tobacco material, the protein-enriched tobacco-derived material, and the one or more sugar alcohols.

2. The protein-enriched smokeless tobacco product of claim 1 , wherein the protein-enriched, tobacco-derived material comprises at least about 80 percent tobacco-derived protein by dry weight.

3. The protein-enriched smokeless tobacco product of claim 2 , wherein at least about 50 percent of the tobacco-derived protein by dry weight is RuBisCO.

4. The protein-enriched smokeless tobacco product of claim 2 , wherein at least about 80 percent of the tobacco-derived protein by dry weight is RuBisCO.

5. The protein-enriched smokeless tobacco product of claim 2 , wherein at least about 50 percent of the tobacco-derived protein by dry weight is F2 proteins.

6. The protein-enriched smokeless tobacco product of claim 1 , wherein the tobacco material comprises particulate tobacco.

7. The protein-enriched smokeless tobacco product of claim 6 , wherein the particulate tobacco comprises a mixture of flue-cured and sun-cured tobacco.

8. The protein-enriched smokeless tobacco product of claim 6 , wherein the particulate tobacco is present in an amount of at least about 10 percent by dry weight.

9. The protein-enriched smokeless tobacco product of claim 1 , wherein the tobacco material comprises a tobacco extract.

10. The protein-enriched smokeless tobacco product of claim 1 , wherein the one or more sugar alcohols are selected from the group consisting of erythritol, arabitol, ribitol, isomalt, maltitol, dulcitol, iditol, mannitol, xylitol, lactitol, sorbitol, and combinations thereof.

11. The protein-enriched smokeless tobacco product of claim 1 , further comprising a natural gum binder in an amount of between about 2 percent and about 10 percent by dry weight.

12. The protein-enriched smokeless tobacco composition of claim 11 , wherein the natural gum binder component is selected from the group consisting of gum arabic, xanthan gum, guar gum, ghatti gum, gum tragacanth, karaya gum, locust bean gum, gellan gum, and combinations thereof.

13. The protein-enriched smokeless tobacco product of claim 1 , further comprising a binder in an amount of between about 5 percent and about 20 percent by dry weight.

14. The protein-enriched smokeless tobacco product of claim 13 , wherein the binder comprises pregelatinized rice starch.

15. The protein-enriched smokeless tobacco product of claim 1 , further comprising one or more fillers in an amount of between about 5 percent and about 20 percent by dry weight.

16. The protein-enriched smokeless tobacco product of claim 15 , wherein the one or more fillers comprise a polysaccharide filler, a starch filler, or a combination thereof.

17. The protein-enriched smokeless tobacco product of claim 15 , wherein the one or more fillers are selected from the group consisting of rice flour, maltodextrin, calcium carbonate, and combinations thereof.

18. The protein-enriched smokeless tobacco product of claim 1 , further comprising an additive selected from the group consisting of flavorants, sweeteners, emulsifiers, disintegration aids, humectants, buffering agents, salts, and combinations thereof.

19. The protein-enriched smokeless tobacco product of claim 1 , wherein the composition further comprises glycerin.

20. The protein-enriched smokeless tobacco product of claim 1 , comprising:
at least about 20 dry weight percent of the tobacco material, wherein the tobacco material comprises particulate tobacco;
and
between about 5 percent and about 20 dry weight percent of a filler, wherein the filler comprises a combination of a polysaccharide filler and a starch filler, and
wherein the tobacco-derived protein comprises at least about 80% by dry weight RuBisCO.

21. The protein-enriched smokeless tobacco product of claim 1 , comprising:
at least about 20 dry weight percent of the tobacco material, wherein the tobacco material comprises particulate tobacco;
at least about 2 dry weight percent of a natural gum binder; and
at least about 10 dry weight percent of a binder other than a natural gum binder,
wherein the tobacco-derived protein comprises at least about 80% by dry weight RuBisCO.

22. The protein-enriched smokeless tobacco product of claim 1 , comprising:
at least about 20 dry weight percent of the tobacco material, wherein the tobacco material comprises particulate tobacco; and
between about 5 percent and about 20 percent by dry weight of a filler, wherein the filler comprises a combination of a polysaccharide filler and a starch filler,
at least about 2 dry weight percent of a natural gum binder; and
at least about 10 dry weight percent of a binder other than a natural gum binder,
wherein the tobacco-derived protein comprises at least about 80% by dry weight RuBisCO.

23. A method of preparing a protein-enriched smokeless tobacco product, comprising:
combining a dry mixture comprising a tobacco material, a protein-enriched, tobacco-derived material; and one or more sugar alcohols, wherein the protein-enriched, tobacco-derived material comprises at least about 60 percent tobacco-derived protein by dry weight, with a wet mixture comprising salt and flavorants to give a combined mixture; and
extruding the combined mixture to give a protein-enriched smokeless tobacco product comprising the protein-enriched, tobacco-derived material in an amount of at least about 2 percent by dry weight and the one or more sugar alcohols in an amount of at least about 10 percent by dry weight,
wherein the product is chewable, and wherein the product is a single layer product comprising a mixture of the tobacco material, the protein-enriched, tobacco-derived material, and the one or more sugar alcohols.
