Abstract

THE INVENTION RELATES TO A METHOD OF TREATING TOBACCO TO REDUCE OR ELIMINATE NITROSAMINES THEREFROM. THE METHOD COMPRISES THE USE OF A SUPERCRITICAL FLUID EXTRACTION MEDIUM AT ELEVATED TEMPERATURE AND PRESSURE TO SELECTIVELY REMOVE NITROSAMINES COMPARED WITH NICOTINE REMOVAL. THE NITROSAMINE CONTENT FOR ALL TOBACCO TYPES CAN BE REDUCED.FIG 1
