Publication number: 20210337857Abstract: The invention provides a tobacco product including a flavorful tobacco composition in the form of an extract of a fire-cured tobacco material. Exemplary tobacco products include smoking articles, smokeless tobacco compositions, and aerosol-generating devices that do not burn tobacco. The invention also provides a process for preparing a smokeless tobacco composition, the method including: mixing a fire-cured tobacco material having a first benzo[a]pyrene concentration with water to produce an aqueous slurry; maintaining the slurry for a time and at a temperature sufficient to form a fire-cured tobacco extract, the aqueous fire-cured tobacco extract exhibiting a second benzo[a]pyrene concentration lower than the first benzo[a]pyrene concentration; separating the aqueous fire-cured tobacco extract from a residual pulp material, and mixing the aqueous fire-cured tobacco extract with a tobacco or non-tobacco plant material to form a smokeless tobacco composition.Type: ApplicationFiled: June 18, 2021Publication date: November 4, 2021Inventors: Crystal Dawn Hege Byrd, William Monroe Coleman, III, Michael Francis Dube, Anthony Richard Gerardi, Eric Taylor Hunt, Darrell Eugene Holton, JR., Charles Bradford Rhoades, JR., Jack Gray Flinchum, JR., Dwayne William Beeson, Jeremy Barrett Mabe

Patent number: 10561168Abstract: The invention provides a tobacco composition for use in a smoking article or a smokeless tobacco composition that includes an additive derived from a flower of the Nicotiana species. The additive can be a flower isolate derived from a flower of the Nicotiana species. In certain embodiments, the flower isolate is in the form of an extract from a flower of the Nicotiana species or in the form of a chemically transformed flower isolate, the chemical transformation being selected from acid/base reaction, hydrolysis, thermal treatment, and enzymatic treatment, the chemical transformation releasing at least a portion of a glycosidically bound compound in the flower of the Nicotiana species. The invention also provides smoking articles and smokeless tobacco compositions that include the flower additives described herein, and methods for preparing an additive derived from a flower of the Nicotiana species for addition to a tobacco composition.Type: GrantFiled: October 6, 2017Date of Patent: February 18, 2020Assignee: R.J.
