14. 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.

15. The protein-enriched smokeless tobacco product of claim 1, wherein the one or more sugar alcohols are present in an amount of from about 10 percent to about 50 percent by dry weight.

16. The protein-enriched smokeless tobacco product of claim 1, wherein the one or more sugar alcohols are present in an amount of from about 10 percent by weight to about 30 percent by weight.

17. 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.

18. The protein-enriched smokeless tobacco composition of claim 17, 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.

19. 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.

20. The protein-enriched smokeless tobacco product of claim 19, wherein the binder comprises pregelatinized rice starch.

21. 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.
