Disclosed is a stabilized substrate composition for smoking articles, particularly cigarettes. In general, the stabilized substrate composition comprises an admixture of a binder and an aerosol forming material which plasticizes the binder, together with optional fillers and/or base materials. In the stabilized substrate compositions of the present invention the relative amounts of binder and aerosol former depend particularly on the situation in which the substrate composition is used. In general, the ratio of aerosol former to binder is between about 3:1 and about 40:1. When the stabilized composition is used on a base material such as tobacco cut filler, the ratio of aerosol former to binder should be at least about 15:1, and preferably is from about 25-35:1, with a maximum ratio of about 40:1. If the composition is formed into a cast sheet, the minimum ratio is about 3:1, the preferred ratio is about 8:1, and the maximum ratio is about 10:1. When the stabilized mixture is printed on a sheet or web substrate, the ratio of aerosol former to binder is generally about 6:1, the maximum ratio is about 10:1, and the minimum ratio is about 3:1.

Substrate material for smoking articles

The present invention relates to a method for providing a reconstituted tobacco material. The process includes contacting tobacco material with a liquid having an aqueous character to provide a mixture (slurry). The slurry is then contacted with a pectin release agent. The tobacco material having released tobacco pectins is then formed into a predetermined shape. The formed slurry having released tobacco pectins is subjected to conditions sufficient to crosslink the released tobacco pectins (e.g., contacting with a crosslinking agent). The formed slurry having crosslinked tobacco pectins is dried to provide a reconstituted tobacco material.

Method for providing a reconstituted tobacco material

The present invention relates to a method for providing a reconstituted tobacco material. The method includes contacting tobacco material dispersed in a liquid having an aqueous character with a humectant or binding agent or both under high shear mixing conditions at a temperature of at least about 35.degree. C. to provide a mixture. The mixture is then contacted with a pectin release agent, preferably at a pH of about 5 to about 9, while maintaining the high shear mixing conditions to provide a tobacco material having released tobacco pectins. Preferably, the tobacco material having released tobacco pectins is then formed into a predetermined shape and subjected to conditions sufficient to cause the released tobacco pectins to undergo crosslinking.
