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.
