Abstract
Methods of modifying the tobacco-specific nitrosamine content of a tobacco material are described herein. One exemplary method comprises contacting a tobacco material with a composition comprising salt, sugar, enzyme, lactic acid bacteria, yeast, or a combination thereof to reduce the total bacterial content; curing the tobacco material; and fermenting the tobacco material in the presence of one or more microorganisms. The method can provide a fermented tobacco material having a tobacco-specific nitrosamine content that is reduced relative to a fermented tobacco material that has not been subjected to the disclosed method steps. In certain embodiments, the tobacco-specific nitrosamine content of the fermented tobacco material is no more than that of the cured tobacco material. Tobacco-containing products including such treated tobacco materials are also provided.
