METHODS FOR FORMING AEROSOL-GENERATING SUBSTRATES HAVING A REDUCED AMOUNT OF TOBACCO-SPECIFIC NITROSAMINES

摘要

There is provided a method of forming an aerosol generating base comprising providing a liquid nicotine source containing at least one tobacco specific nitrosamine, mixing the liquid nicotine source with a solvent and at least one aerosol forming agent to form an aerosol generating Forming a substrate, and irradiating the aerosol generating substrate with ultraviolet light to reduce the amount of at least one tobacco specific nitrosamine. There is also provided a method of forming an aerosol generating base comprising providing a tobacco slurry containing at least one tobacco specific nitrosamine, irradiating the tobacco slurry with ultraviolet light to increase the amount of at least one tobacco specific nitrosamine And drying the tobacco slurry to form an aerosol generating base.
