Abstract: A method of preparing a tobacco material for use in a smoking article is provided, including (i) mixing a tobacco material, water, and an additive selected from the group consisting of lysine, glycine, histidine, alanine, methionine, glutamic acid, aspartic acid, proline, phenylalanine, valine, arginine, di- and trivalent cations, asparaginase, saccharides, phenolic compounds, reducing agents, compounds having a free thiol group, oxidizing agents, oxidation catalysts, plant extracts, and combinations thereof; (ii) heating the mixture; and (iii) incorporating the heat-treated mixture into a smoking article as a smokable material. A smoking article in the form of a cigarette is also provided that includes a tobacco material pre-treated to inhibit reaction of asparagine to form acrylamide in mainstream smoke. Upon smoking, the smoking article is characterized by an acrylamide content of mainstream smoke that is reduced relative to an untreated control smoking article.

Abstract: A method for preventing packing of tobacco in a tobacco hopper is provided. The method comprises the steps of providing a feed screw with a plurality of pins extending from an outer diameter of the feed screw and providing an agitator with a plurality of pins extending from an outer diameter of said outer diameter. The feed screw and said agitator screws are rotated in opposite directions to move tobacco through the hopper.

Abstract: A composition intended to be employed for therapeutic purposes incorporates a source of nicotine and at least one levulinate moiety. Representative forms of nicotine include free base (e.g., as a mixture of nicotine and microcrystalline cellulose), a nicotine salt (e.g., as nicotine bitartrate) or nicotine polacrilex. The levulinate moiety can have the form of an acid (e.g., levulinic acid), a levulinate salt (e.g., sodium levulinate), or an ester of levulinic acid (e.g., methyl levulinate or ethyl levulinate). The composition can incorporate nicotine and levulinic acid in a salt form (e.g., nicotine levulinate). The composition can be composed of at least two forms of nicotine, and one of the forms of nicotine is in the form of nicotine levulinate. The composition is useful for treatment of central nervous system conditions, diseases, and disorders, and as a nicotine replacement therapy.

Abstract: The invention provides a process for preparing a tobacco composition suitable for use as a smokeless tobacco composition, including: providing a moist tobacco material; heating the moist tobacco to a temperature of at least about 85° C. for a time sufficient to pasteurize the tobacco material while maintaining the moisture content at a relatively constant level; adding an amount of a base and water to the moist tobacco material sufficient to raise the pH of the slurry to at least about 8.7 and raise the moisture content to at least about 40% by weight, thereby forming a pH-adjusted moist tobacco material; and continuing to heat the pH-adjusted moist tobacco material to a temperature of at least about 55° C. for a time sufficient for the pH of the moist tobacco material to drop to less than about 8.5 while maintaining the moisture content at a relatively constant level.

Abstract: 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.
