Abstract

A meltable smokeless tobacco composition configured for insertion into the mouth of a user is provided. The smokeless tobacco composition includes a tobacco material and a lipid having a melting point of about 36° C. to about 45° C. An associated process is also provided. The process includes melting a lipid having a melting point of about 36° C. to about 45° C. to form a molten lipid composition, mixing a tobacco material with the molten lipid composition to form a molten smokeless tobacco composition, and cooling the molten smokeless tobacco composition to form a solidified smokeless tobacco composition.

Claims

1. A process for preparing a meltable smokeless tobacco composition configured for insertion into the mouth of a user, comprising:

melting a lipid having a melting point of about 36°

C. to about 45°

C. to form a molten lipid composition;

preparing a spray-dried or freeze-dried mixture of tobacco extract and a second particulate material by mixing an aqueous tobacco extract with an amount of the second particulate material sufficient to provide a mixture with a solids content of at least about 18 weight percent, and thereafter subjecting the mixture to spray-drying or freeze-drying to form a dry particulate material;

mixing the spray-dried or freeze-dried mixture with the molten lipid composition to form a molten smokeless tobacco composition; and

cooling the molten smokeless tobacco composition to form a solidified smokeless tobacco composition.

2. The process of claim 1, wherein the second particulate material is a filler or binder material.

3. The process of claim 1, wherein the second particulate material is selected from the group consisting of maltodextrin, cyclodextrin, and natural gums.

4. The process of claim 1, wherein the weight ratio of tobacco extract to second particulate material in the dry particulate material is about 7:

1 to about 1;

1.

5. The process of claim 1, wherein the weight ratio of tobacco extract to second particulate material in the dry particulate material is about 5:

1 to about 2;

1.

6. The process of claim 1, further comprising the step of adding a sugar alcohol to the molten smokeless tobacco composition.

7. The process of claim 6, wherein the solidified smokeless tobacco composition comprises at least about 30 dry weight percent of the lipid and at least about 20 dry weight percent of the sugar alcohol.

8. The process of claim 1, wherein the lipid has a melting point of about 38°

C. to about 41°

C.

9. The process of claim 1, wherein the lipid is an animal or plant derived fat, wax, or oil.

10. The process of claim 1, wherein the lipid is a plant-derived fat comprising a plurality of saturated or unsaturated fatty acid chains having a carbon length of about 14 to about 20 carbon atoms.

11. The process of claim 1, wherein the lipid comprises a blend of palm kernel oil and palm oil.

12. The process of claim 1, further comprising the step of adding a salt to the tobacco extract-containing mixture prior to the mixing step.

13. The process of claim 1, further comprising the step of adding an additional component to the molten smokeless tobacco composition, the additional component being selected from the group consisting of flavorants, binders, fillers, disintegration aids, humectants, and mixtures thereof.

14. The process of claim 1, further comprising the step of depositing the molten smokeless tobacco composition in a mold so as to form the molten smokeless tobacco composition into a predetermined shape.
