A method of forming a carbon material from the stalk or roots of a plant of thespecies is provided herein, wherein the method includes i) receiving a tobacco material comprising at least one of a stalk material and a root material of a harvested plant of thespecies; and ii) pyrolyzing the tobacco material to remove volatiles and to form a tobacco-derived carbon material. Optionally, the method can further include activating the tobacco-derived carbon material. The tobacco-derived carbon material can be incorporated into a tobacco product. A carbon material derived from pyrolyzing a tobacco material in the form of at least one of a tobacco stalk material and a tobacco root material of a harvested plant of thespecies is also provided herein.

Tobacco-derived carbon material

A device and method for delivering a therapeutic drug to a patient in the form of an aerosol includes a heat generating chamber and an aerosol forming chamber separated by a heat conductor. A heating element is disposed within the heat generating chamber in heat conducting relation with the heat conductor. A substrate having a therapeutic drug and an aerosol forming agent deposited thereon is disposed within the aerosol forming chamber in heat conducting relation with the heat conductor. The heating element ignites a fuel source consisting essentially of a combustible liquefied gas to generate heat that is conducted to the heat conductor and then to the substrate via the heat conductor. The heat generated by the heating element activates the aerosol forming agent to volatilize the therapeutic drug into an aerosol drug contained within the aerosol forming chamber and made available to be inhaled by the patient.

A reconstituted tobacco material incorporates an exogenous tocopherol or derivative thereof, such as in the amount of at least about 0.1 weight percent. A tobacco blend can be formed by combining reconstituted tobacco material incorporating such an additive with one or more additional tobacco materials, such as burley tobacco, Oriental tobacco, and flue-cured tobacco. A smoking article, such as a cigarette, contains such a reconstituted tobacco, as part of the smokable material, as part of tobacco paper wrapping material, or as part of a reconstituted tobacco-containing filter element. The invention also provides a method of forming reconstituted tobacco material wherein a tocopherol or derivative thereof is added to the tobacco material, either by adding the tocopherol to an aqueous extract or water insoluble pulp formed during the reconstituted tobacco process or by adding the tocopherol to the solid reconstituted tobacco sheet after the aqueous extract and pulp are recombined.

Reconstituted tobaccos containing additive materials

A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with a burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. A preferred aerosol forming material is glycerin. An outer paper wrapper circumscribes the length of the smokable rod, and another paper wrapping material also can circumscribe the inner core material. In use, one end of the smokable rod is lit, and the tobacco cut filler of the inner core burns to yield tobacco smoke. The outer material smolders, and hence thermal decomposition products of the outer tobacco material and volatilized aerosol forming material are produced. Alternatively, a smokable rod can be provided by positioning the tobacco cut filler in the outer annular region, and by constructing the inner core portion using the tobacco material treated with aerosol forming material and a burn suppressing agent.

Smokable rod for a cigarette

A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. A longitudinally extending inner core of tobacco cut filler is positioned within a smokable rod. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with a burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. In use, one end of the smokable rod is lit, and the tobacco cut filler of the inner core burns to yield tobacco smoke. The outer material smolders, and hence thermal decomposition products of the outer tobacco material and volatilized aerosol forming material are produced. When the opposite end of the smokable rod is drawn upon, an aerosol composed of tobacco smoke, thermal decomposition products of tobacco, and volatilized aerosol forming material, is provided.

A method for chemically modifying a tobacco material during a curing process involves treating the tobacco material in a curing enclosure at a temperature and for a time sufficient to produce cured tobacco. The method also involves contacting the tobacco material with a chemical reagent before and/or during the time period that the tobacco material is cured so that the chemical reagent can interact with the tobacco material, thus resulting in further change in the chemical nature of the cured tobacco material. An exemplary chemical reagent is an ammonia source, which can be applied to a tobacco material in a variety of ways, including by spraying an aqueous ammonia source onto the tobacco or by introducing gaseous ammonia into the curing enclosure during the curing process.

Processes for producing flavorful and aromatic compounds from tobacco material are provided. The processes involve providing a tobacco suspension comprising finely ground tobacco material, and subjecting the tobacco suspension to heat treatment in an enclosed, pressure controlled, and generally inert environment at a temperature of at least 140&deg; C.

Method of providing flavorful and aromatic tobacco suspension

Improved flavorful and aromatic tobacco materials and a method for producing flavorful and aromatic components from all natural tobacco materials are provided. A first tobacco material is contacted with a second tobacco material to form a tobacco blend. The first tobacco material has a higher content of nitrogen source and a lower content of sugar source than the second tobacco material. The moisture content in the first and second materials of the tobacco blend is increased to at least about 20%. The tobacco blend having an increased moisture content is then subjected to heat treatment in a substantially atmospheric environment for a time and under conditions sufficient to generate flavorful and aromatic substances in said first and second tobacco materials.

A low-density filler material for cigarettes from either a low-density tobacco composition or an extruded grain or starch composition. The low-density tobacco composition and a method of making the low-density tobacco composition by extruding a mixture of tobacco and flour or tobacco and starch under conditions whereby the solvent in the extruded mixture flashes into vapor upon release from the extrusion head. The low-density tobacco composition is formed without the aid of an added binder. The low-density flour or starch material and a method of making it by extruding flour or starch with a filler material such as calcium carbonate under conditions whereby the solvent in the extruded mixture flashes into vapor upon extrusion through the orifice die. The extruded composition can then be cut and used in place of cut tobacco filler.

The process of the present invention involves extracting components from a tobacco material or other plant material using a solvent having an aqueous character to provide separately an aqueous tobacco extract and a water insoluble tobacco portion. The insoluble tobacco portion is refined and a slurry is produced. The slurry is formed into a predetermined shape, e.g., a formed web. The formed web can be pressed to reduce the moisture content. The tobacco material preferably has a moisture content of at least about 50 percent by weight. The material is contacted with an aqueous mixture of an aerosol precursor material. The ratio of liquid having an aqueous character to aerosol precursor material is typically from about 25 to 75 percent by weight. Immediately after the introduction of the aerosol precursor material, the web is dried at a preselected temperature so that the aerosol precursor material is dispersed evenly throughout the web.

Tobacco reconstitution process

A cigarette has a blend of tobacco materials and a filter element provided from a non-woven thermoplastic material. The non-woven material comprises polyester or polypropylene fibers. The non-woven material is in intimate contact with a high molecular weight material (e.g., an emulsifier or another polymeric material). As such the filter material is coated with another polymeric material. The coated non-woven material can be in intimate contact with an acidic material (e.g., lactic acid) or a basic material (e.g., sodium hydroxide). Certain cigarettes can have relatively high nicotine smokable blends and filter elements having the coated non-woven filter material in intimate contact with an acidic material. Certain other cigarettes can have relatively low nicotine smokable blends and filter elements having the coated non-woven filter material in intimate contact with a basic material. Certain other cigarettes can be 'ultra low tar' cigarettes including filter elements having the coated non-woven filter material in intimate contact with a basic material.
