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. Heat-treated tobacco composition prepared according to the method are also provided, such as heat-treated smokeless tobacco composition comprising a tobacco material, water, flavorant, binder, and filler, the heat-treated smokeless tobacco composition having an acrylamide content of less than about 2000 ppb.
