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 smokeless tobacco product includes a powdered or granular smokeless tobacco formulation that is contained within a moisture-permeable packet or pouch. The smokeless tobacco formulation may include finely ground particles of tobacco in powder-like form and other ingredients such as sweeteners, binders, colorants, pH adjusters, fillers, flavoring ingredients, disintegration aids, antioxidants and preservatives. The tobacco formulation may have a dry or moist form. The container has the form of a pouch or bag, such as is the type commonly used for the manufacture of snus products. The container preferably contains at least one capsule, such as a spherical breakable capsule. The container is intended to be placed in the mouth of the tobacco user, such that the tobacco formulation within the container may be enjoyed by the user. After the tobacco user is finished using the smokeless tobacco product, the container is removed from the user's mouth for disposal.

Abstract: A method of thermally processing a tobacco material is provided, the method including the steps of (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, to form a moist tobacco mixture; (ii) heating the moist tobacco mixture at a temperature of at least about 60° C. to form a heat-treated tobacco mixture; and (iii) incorporating the heat-treated tobacco mixture into a tobacco product.

Abstract: A smokeless tobacco product configured for insertion into the mouth of a user of the product is provided, the tobacco product including a water-permeable pouch containing a tobacco formulation, the tobacco formulation including a tobacco material and a plurality of microcapsules dispersed within the tobacco material, the plurality of microcapsules including an outer shell encapsulating an internal payload. The internal payload may include an additive such as water, flavorants, binders, colorants, pH adjusters, buffering agents, fillers, disintegration aids, humectants, antioxidants, oral care ingredients, preservatives, additives derived from herbal or botanical sources, and mixtures thereof. Microencapsulated flavorants include tobacco-containing flavorants, such as tobacco extracts or a particulate tobacco material, sweeteners (e.g., sweeteners containing neotame), and vanillin (optionally in a complexed form).

Abstract: The invention provides a process for preparing a tobacco composition suitable for use as a smokeless tobacco composition, the process including: providing a slurry comprising water and a tobacco material, the slurry comprising at least about 75% by weight water, based on the total weight of the slurry; heating the slurry to a temperature of at least about 60° C. for a time sufficient to pasteurize the tobacco material; adding an amount of a base to the slurry sufficient to raise the pH of the slurry to at least about 8.5, thereby forming a pH-adjusted slurry; and continuing to heat the pH-adjusted slurry to a temperature of at least about 60° C. for a time sufficient for the pH of the slurry to drop at least about 0.5 pH unit following the adding step.
