Abstract

An oral tobacco product includes a body that is wholly receivable in an oral cavity. The body includes a mouth-stable polymer matrix and tobacco fibers embedded in the mouth-stable polymer matrix. The oral tobacco product can be formed by extruding a mixture of mouth-stable polymer and tobacco fibers.

Claims

1. An oral tobacco product, comprising:

a body that is wholly receivable in an oral cavity, the body including, a fiber-polymer matrix including,

a mouth-stable polymer matrix including polyurethane in an amount greater than or equal to about 60 weight percent; and

tobacco fibers in an amount greater than or equal to about 10 weight percent, the tobacco fibers being embedded in the mouth-stable polymer matrix; and

an additive absorbed in the fiber-polymer matrix, the additive configured to be released from the body when the body is received within the oral cavity and exposed to saliva, and the tobacco fibers forming channels extending from one surface of the oral tobacco product to an opposite surface of the oral tobacco product in the fiber-polymer matrix.

2. The oral tobacco product of claim 1, further comprising:

a plasticizer dispersed in the fiber-polymer matrix.

3. The oral tobacco product of claim 2, wherein the plasticizer includes propylene glycol, glycerin, vegetable oil, triglycerides, or any combination thereof.

4. The oral tobacco product of claim 1, further comprising:

a sweetener dispersed in the body.

a supplemental additive including minerals, vitamins, dietary supplements, nutraceuticals, energizing agents, soothing agents, amino acids, chemesthetic agents, antioxidants, botanicals, teeth whitening agents, therapeutic agents, or any combination thereof, wherein the supplemental additive is dispersed in the body or the tobacco fibers such that the supplemental additive is released when the body is held within a mouth of an adult tobacco consumer.

8. The oral tobacco product of claim 1, further comprising:

a flavorant dispersed in the body, such that the flavorant is released when the body is held within a mouth of an adult tobacco consumer.

9. The oral tobacco product of claim 8, wherein the flavorant includes licorice, wintergreen, cherry and berry type flavorants, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cinnamon, cardamon, apium graveolens, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, Japanese mint, cassia, caraway, cognac, jasmine, chamomile, menthol, ylang-ylang, sage, fennel, pimenta, ginger, anise, coriander, coffee, mint oils from a species of the genus Mentha, or any combination thereof.

10. The oral tobacco product of claim 1, further comprising:

an antioxidant.

11. The oral tobacco product of claim 10, wherein the oral tobacco product includes the antioxidant in an amount ranging from about 0.01 weight percent to about 5.0 weight percent.

12. The oral tobacco product of claim 10, wherein the antioxidant includes ascorbyl palmitate, BHT, ascorbic acid, sodium ascorbate, monosterol citrate, tocopherols, propyl gallate, tertiary butylhydroquinone (TBHQ), butylated hydroxyanisole (BHA), Vitamin E, or any combination thereof.

13. The oral tobacco product of claim 1, further comprising:

a soluble fiber.

14. The oral tobacco product of claim 13, wherein the soluble fiber includes maltodextrin.

15. The oral tobacco product of claim 1, wherein the body has a compressibility @ 250 N ranging from about 45% to about 95%.

16. The oral tobacco product of claim 1, wherein the body has a compressibility @ 425 N ranging from about 60% to about 99%.

17. The oral tobacco product of claim 1, wherein the body has a percentage of springiness of greater than or equal to about 20%.

18. The oral tobacco product of claim 1, wherein the body is shield shaped.

19. The oral tobacco product of claim 1, wherein the body has a diameter ranging from about 5 to about 25 millimeters and a thickness ranging from about 1 to about 10 millimeters.

20. The oral tobacco product of claim 1, further comprising:

non-tobacco cellulosic fibers.

21. The oral tobacco product of claim 1, further comprising:

a flavorant dispersed in the tobacco fibers such that the flavorant is released when the body is held within a mouth of an adult tobacco consumer.
