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: An improved pouching machine is provided. The improved pouching machine comprises a feed hopper with a first and a second end and a feed screw with a plurality of pins extending from the circumference. The feed screw is connected to a first shaft and the first shaft is connected to a motor to rotate the first shaft. An agitator screw is positioned adjacent to the feed screw and has a plurality of pins extending from the circumference. The agitator screw is connected to a second shaft.

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 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.

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.

Abstract: A system and method for evaluating an inventory management strategy combines multiple management strategies in a single inventory management system. The system analyzes the inventory portfolio on an item-by-item basis to assign the most suitable management strategy for that item. The inventory management system provides a high level of flexibility for the users to define input parameters to ensure a desired level of customer satisfaction. Additionally, it determines whether the inventory items are forecastable before predicting future demands.
