Smoking composition comprising flavour precursor

Abstract

A smoking composition comprises an aerosol-forming substrate and a flavour precursor compound. Upon heating, the precursor compound releases a thiol-containing flavour compound or intermediate that enhances the flavour experience of the aerosol-forming substrate when used in a smoking article. The smoking article may include tobacco and may be configured to heat, but not combust, the tobacco.

1 . (canceled) 
     
     
         2 . A smoking article comprising:
 an aerosol forming substrate comprising tobacco;   a heating element configured to heat, but not combust, the aerosol forming substrate;   a flavour precursor compound added to the aerosol forming substrate, wherein the flavour precursor compound releases a thiol-containing flavour compound upon heating of the aerosol forming substrate by the heating element,   wherein heating of the aerosol forming substrate and the flavour precursor compound results in the production of furfurylthiol.   
     
     
         3 . A smoking article according to  claim 2 , wherein the flavour precursor compound is configured to release the flavour compound at a temperature of from about 200° C. to about 450° C. 
     
     
         4 . A smoking article according to  claim 3 , further comprising nicotine or a source of nicotine.
