Abstract: A filtered cigarette possesses at least one breakable capsule in its filter element. The filter element can possess a central cavity extending from the cigarette tobacco rod towards the middle of the filter element. The central cavity may be defined by an inner filter portion. The inner filter portion can be surrounded by an outer filter portion comprised of filter tow material that is generally permeable to the smoke generated by the cigarette. At least one breakable capsule is disposed in the central cavity of the filter element. The breakable capsules are spherical in shape, and are composed of a gelatin outer shell that encloses a payload of triglycerides and flavoring agents. The breakable capsules are adapted to rupture in response to pressure applied by the smoker to the outside region of the filter element.

Abstract: 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.
