Abstract
A method for reducing the tobacco specific nitrosamines (TSNAs) in tobacco and tobacco smoke is provided. The tobacco is combined with a solvent to form a soluble extracts fraction and an insoluble residue fraction. The soluble extracts fraction is contacted with a nitrosamine-reducing material to provide a soluble extracts fraction having a reduced level of TSNAs. The nitrosamine-reducing material may comprise a sepiolite. The insoluble residue fraction is contacted with an alkali extractant to provide an insoluble residue fraction having a reduced level of TSNAs. The alkali extractant may comprise a hydroxide. The soluble extracts fraction having a reduced level of TSNAs and insoluble residue fraction having a reduced level of TSNAs may be recombined to form a reconstituted tobacco product having a reduced level of TSNAs. The TSNAs may be reduced by at least about 30%, such as at least about 40%, such as at least about 50%.
