J. Reynolds Tobacco Company - Inventors: John-Paul Mua; Eric Taylor Hunt - Web page: https://patentgrep.com/patent/US20130152953A1 ## CPC - A24B 15/18: Treatment of tobacco products or tobacco substitutes - A24B 13/00: Tobacco for pipes, for cigars, e.g. cigar inserts, or for cigarettes; Chewing tobacco; Snuff (reconstituted tobacco products A24B3/14) - A24B: MANUFACTURE OR PREPARATION OF TOBACCO FOR SMOKING OR CHEWING; TOBACCO; SNUFF ## Abstract The invention provides a smokeless tobacco composition adapted for oral use, the composition including a tobacco material and an effervescent material. The effervescent material includes a sugar material containing an entrapped gaseous component, such that release of the entrapped gaseous component occurs upon dissolution of the sugar material in the oral cavity. The invention also provides a method for making a smokeless tobacco composition that involves mixing a tobacco material with an effervescent material, the mixing step including either admixing a granulated composition comprising a tobacco material with a gasified sugar material in particulate form, or forming a gasified sugar material in situ by mixing a water source with a molten composition comprising a tobacco material and a sugar alcohol. ## Claims ### Claim 1 A smokeless tobacco composition adapted for introduction into the oral cavity, comprising: (a) a tobacco material; and (b) an
