Tobacco filling for non-combustion-type heating smoking article

Abstract

The present invention provides a tobacco raw material having a good inhalation flavor and a method for manufacturing same. Provided is a tobacco raw material in which the ratio of the weight of extracts obtained by extraction using n-hexane as a solvent to the weight of extracts obtained by further extraction using water as a solvent after the abovementioned extraction is a water-extracted weight/hexane-extracted weight ratio of 0-1.5.

What is claimed is: 
     
         1 . A tobacco filler for a non-combustion smoking article comprising a shredded tobacco, and a liquid that generates aerosol, wherein
 the tobacco filler contains an acid that has a first acid dissociation constant of 4.0 to 6.0 inclusive and a boiling point of 366° C. to 600° C. inclusive.   
     
     
         2 . The tobacco filler according to  claim 1 , wherein the acid is at least one selected from the group consisting of ascorbic acid, isoascorbic acid, heneicosanoic acid, lignoceric acid, octacosanoic acid and nonadecanoic acid. 
     
     
         3 . The tobacco filler according to  claim 1 , wherein the tobacco filler containing the acid at 0.25% by mass to 10% by mass inclusive of the whole tobacco filler. 
     
     
         4 . The tobacco filler according to  claim 1 , wherein the liquid that generates aerosol contains propylene glycol (PG).
