Reconstituted tobacco for non-combustion-heating-type flavor inhaler and method for manufacturing same, non-combustion-heating-type flavor inhaler, and non-combustion-heating-type flavor inhaling system

Abstract

Provided is a reconstituted tobacco enabling control of power consumption per one non-combustion-heating-type flavor inhaler during use. The reconstituted tobacco for a non-combustion-heating-type flavor inhaler contains a tobacco material and a tobacco component, wherein the tobacco material has a maximum absorbance of 0.40 or more in the wavelength range of 3200 to 3600 cm−1 in a FT-IR analysis, and the specific heat of the tobacco material is 5 mJ/mg·° C. or less.

1 . A reconstituted tobacco for a non-combustion-heating-type flavor inhaler, the reconstituted tobacco comprising a tobacco material and a tobacco component,
 wherein the tobacco material has a maximum absorbance of 0.40 or more at wavelengths from 3200 to 3600 cm −1  in FT-IR analysis, and   the tobacco material has a specific heat of 5 mJ/mg·° C. or less.   
     
     
         2 . The reconstituted tobacco according to  claim 1 , wherein an amount of water absorption when the tobacco material is immersed in water at 23° C. for 900 seconds is from 4.0 to 6.0 g/g. 
     
     
         3 . The reconstituted tobacco according to  claim 1 , wherein the tobacco material has an angle of repose of 400 or less. 
     
     
         4 . The reconstituted tobacco according to  claim 1  comprising a tobacco extract obtained by extracting the tobacco component from a tobacco raw material. 
     
     
         5 . The reconstituted tobacco according to  claim 1 , further comprising a binder. 
     
     
         6 . The reconstituted tobacco according to  claim 1 , further comprising a fiber material. 
     
     
         7 . The reconstituted tobacco according to  claim 1 , wherein the reconstituted tobacco is a reconstituted tobacco in sheet form, or a reconstituted tobacco in a form of sheet shreds obtained by shredding the reconstituted tobacco in sheet form. 
     
     
         8 . A non-combustion-heating-type flavor inhaler comprising a tobacco-containing segment filled with the reconstituted tobacco according to  claim 1 . 
     
     
         9 . A non-combustion-heating-type flavor inhaling system comprising:
 the non-combustion-heating-type flavor inhaler according to claim  8 ; and   a heating device that heats the tobacco-containing segment.   
     
     
         10 . A method for manufacturing the reconstituted tobacco according to  claim 1 , the method comprising:
 a step of extracting a tobacco component from a tobacco raw material to obtain a tobacco extract and a tobacco residue;   a step of subjecting the tobacco residue to an alkaline digestion treatment and then adjusting pH to 4.0 to 6.5; and   a step of adding the tobacco extract back to the tobacco residue after pH adjustment.   
     
     
         11 . The method according to  claim 10 , wherein the alkaline digestion treatment involves adding an alkali metal hydroxide to the tobacco residue and heating the tobacco residue at 130 to 230° C. for 5 minutes to 6 hours.
