Abstract

See full text

The invention relates to method of treating a material containing nicotine and at least one nitrosamine to reduce the quantity of nitrosamine therein and to methods of producing a tobacco extract with reduced nitrosamine content. The methods comprise contacting tobacco with a solvent to produce a liquid phase tobacco extract containing nitrosamines and treating the liquid phase tobacco extract to decompose the nitrosamines in the liquid phase. The liquid phase extract may then be treated to reduce nitrosamine decomposition products therein. The invention also relates to tobacco material produced using these methods and to tobacco products incorporating such tobacco material.
