Production method for tobacco flavored liquid, tobacco flavored liquid, reconstituted tobacco material, and flavor inhaler

Abstract

Provided is a production method for a tobacco flavored liquid for use in a flavor inhaler that generates aerosols, said production method comprising: heating a tobacco material to vaporize a flavor component from the tobacco material; dissolving, in a first liquid as an aerosol source, a gas containing the flavor component to obtain a flavor component-containing liquid; and distilling the flavor component-containing liquid at a temperature lower than the boiling point of the first liquid to obtain a tobacco flavored liquid.

What is claimed is: 
     
         1 . A production method for a tobacco flavored liquid for use in an aerosol-generating flavor inhaler, the method comprising:
 heating a tobacco material to vaporize flavor components from the tobacco material;   dissolving a gas containing the flavor components in a first liquid which serves as an aerosol source to obtain a flavor component-containing liquid; and   distilling the flavor component-containing liquid at a temperature below a boiling point of the first liquid to obtain the tobacco flavored liquid.   
     
     
         2 . The method according to  claim 1 , wherein the distilling is conducted at a temperature higher than 100° C. 
     
     
         3 . The method according to  claim 1 , wherein the distilling is conducted at a temperature equal to or above the boiling point of the first liquid minus 40° C. 
     
     
         4 . The method according to  claim 1 , wherein the first liquid is propylene glycol, glycerin, or a mixture of propylene glycol and glycerin. 
     
     
         5 . The method according to  claim 4 , wherein the distilling is conducted at a temperature in a range of 150 to 180° C. 
     
     
         6 . The method according to  claim 1 , further comprising adding a second liquid which serves as an aerosol source to the tobacco material before the heating. 
     
     
         7 . The method according to  claim 6 , wherein the second liquid is propylene glycol, glycerin, or a mixture of propylene glycol and glycerin. 
     
     
         8 . The method according to  claim 1 , wherein the heating is conducted at a temperature of 150 to 400° C. 
     
     
         9 . The tobacco flavored liquid obtainable by the method according to  claim 1 . 
     
     
         10 . A flavor inhaler comprising the tobacco flavored liquid according to  claim 9 . 
     
     
         11 . A flavor inhaler comprising the tobacco flavored liquid according to  claim 9  and an atomization unit for atomizing the tobacco flavored liquid. 
     
     
         12 . A reconstituted tobacco material comprising:
 the tobacco flavored liquid obtainable by the method according to  claim 1 ; and   a post-heating tobacco material obtainable at the time of obtaining the gas containing the flavor components in the method according to  claim 1 .   
     
     
         13 . A flavor inhaler comprising the reconstituted tobacco material according to  claim 12 .
