Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed: 1. A method of preparing a tobacco material for use in a smoking article, comprising: (i) mixing a tobacco material, water, a buffering agent that buffers within a pH range of about 6 to about 10 and an additive capable of inhibiting reaction of asparagine to form acrylamide upon heating or burning of the tobacco material, thereby forming a moist tobacco mixture, wherein the additive is asparaginase; (ii) heating the moist tobacco mixture to form a heat-treated…
