Material for Inclusion in a Smoking Article

Abstract

The invention relates to inclusion of one or more sugars or isolated sugars in a smoking article.

1 . A method of reducing the level of one or more tobacco specific nitrosamines (TSNAs) generated by a smoking article in use, comprising applying one or more sugars to smokeable material for incorporation into the smoking article. 
     
     
         2 . Use of one or more sugars to reduce the level of one or more tobacco specific nitrosamines (TSNAs) in mainstream smoke generated upon use of a smoking article, wherein the one or more sugars are applied to smokeable material for incorporation into the smoking article. 
     
     
         3 . A method as claimed in  claim 1 , or a use as claimed in  claim 2 , wherein the one or more sugars comprise one or more of: arabinose, rhamnose, galactose, glucuronic acid, allose, altrose, glucose, mannose, gulose, idose, talose, psicose, fructose, sucrose, sorbose, tagatose, lyxose, ribose, ribulose, xylose, xylulose, invert sugar and derivatives thereof, including monosaccharide and disaccharide derivatives. 
     
     
         4 . A method as claimed in  claim 1  or  claim 3 , or a use as claimed in  claim 2  or  claim 3 , wherein the one or more sugars are applied as a solution or in particulate form. 
     
     
         5 . A method as claimed in any of  claims 1 ,  3  or  4 , or a use as claimed in any of  claims 2 - 4 , wherein the smokeable material comprises tobacco. 
     
     
         6 . A method or a use as claimed in  claim 5 , wherein the one or more sugars are applied to the tobacco. 
     
     
         7 . A method as claimed in any of  claims 1 ,  3 ,  4 ,  5  or  6 , or a use as claimed in any of  claims 2 - 6 , wherein the one or more sugars are applied to the smokeable material in an amount of about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9% or about 10% (w/w). 
     
     
         8 . A method as claimed in any of  claims 1 ,  3 ,  4 ,  5 ,  6  or  7 , or a use as claimed in any of  claims 2 - 7 , wherein the level of one or more TSNAs is reduced by at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40% or at least about 45% compared to a control smoking article. 
     
     
         9 . A smokeable material for inclusion in a smoking article, the material comprising tobacco, and one or more isolated sugars selected from the group consisting of: arabinose, rhamnose, glucuronic acid, allose, altrose, gulose, idose, talose, psicose, sorbose, tagatose, lyxose, ribose, ribulose, xylulose and derivatives thereof, including monosaccharide and disaccharide derivatives. 
     
     
         10 . A smokeable material as claimed in  claim 9 , wherein the one or more isolated sugars are applied to the tobacco. 
     
     
         11 . A smokeable material as claimed in  claim 10 , wherein the one or more isolated sugars are applied to the tobacco as a solution or in particulate form. 
     
     
         12 . A smokeable material as claimed in any of  claims 9 - 11 , wherein the smokeable material comprises about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9% or about 10% of the one or more isolated sugars (w/w). 
     
     
         13 . A smokeable sheet material for inclusion in a smoking article, the sheet material comprising a filler and one or more isolated sugars selected from the group consisting of arabinose, rhamnose, glucuronic acid, allose, altrose, gulose, idose, talose, psicose, sorbose, tagatose, lyxose, ribose, ribulose, xylulose and derivatives thereof, including monosaccharide and disaccharide derivatives. 
     
     
         14 . A smokeable sheet material as claimed in  claim 13 , wherein the filler comprises one or more of a binder, a diluent and a filling agent. 
     
     
         15 . A method of preparing a sheet of smokeable material for inclusion in a smoking article, wherein the method comprises preparing, casting and drying a solution or slurry comprising a filler and one or more isolated sugars. 
     
     
         16 . A smokeable material as claimed in any of  claims 9 - 12 , or a smokeable sheet material as claimed in any of  claims 13  or  14 , wherein the level of one or more TSNAs in smoke generated upon use of the smoking article into which the smokeable material or smokeable sheet material is incorporated is reduced compared to a control smoking article. 
     
     
         17 . A smoking article comprising a smokeable material according to any of  claims 9 - 12 , or a smokeable sheet material according to any of  claims 13  or  14 . 
     
     
         18 . A smoking article as claimed in  claim 17 , having a reduced level of one or more TSNAs in the mainstream smoke generated upon use of the article.
