摘要： 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.
