METHOD FOR PRODUCING A HEAT-IRREVERSIBLY COAGULATED GLUCAN SHEET CONTAINING A LEAF TOBACCO EXTRACT AND METHOD FOR PRODUCING A TOBACCO FLAVOR-GENERATING MEDIUM USING A HEAT-IRREVERSIBLY COAGULATED GLUCAN SHEET

摘要

A leaf tobacco extract or a concentrate thereof is used as a dispersion medium, which is mixed with powder of a heat-irreversibly coagulating glucan and a dispersion interference-preventing agent including an organic acid. The resultant mixture is stirred to disperse the powder of glucan into the dispersion medium, thereby preparing a slurry having an increased viscosity. This slurry is formed into a sheet, which is then heated and coagulated.
