Tobacco extract composition and production method therefor

Abstract

A production method for a tobacco extract composition, comprising: a heating step for heating a tobacco starting material such that the temperature of the starting material is 100-270° C.; and a recovery step for recovering volatile components generated in the heating step.

1 . A production method for producing a tobacco extract composition, comprising:
 a heating step of heating a tobacco raw material so that a temperature of the raw material becomes 100 to 270° C.; and   a recovery step of recovering volatile components generated in the heating step.   
     
     
         2 . The production method according to  claim 1 , wherein the temperature is 200 to 250° C. 
     
     
         3 . The production method according to  claim 1 , wherein a particle size of the tobacco raw material measured in accordance with ASTM E11-95 is 0.5 to 2 mm. 
     
     
         4 . The production method according to  claim 1 , wherein the tobacco raw material is selected from burley tobacco, flue-cured tobacco, or a combination of burley tobacco and flue-cured tobacco. 
     
     
         5 . The production method according to  claim 1 , wherein

       where D 1  is a diameter of a pipe from which the volatile components are discharged in the heating step, and D 2  is a diameter of a pipe into which the volatile components are introduced in the recovery step. 
     
     
         6 . A tobacco extract composition produced by using the production method according to  claim 1 . 
     
     
         7 . The tobacco extract composition according to  claim 6 , wherein, when a concentration of a polyol component is 15 to 35% by weight, a turbidity (OD660) of the tobacco extract composition measured by using a spectrophotometer is 0.90 to 1.80.
