Abstract
A method for producing a non-combustion type tobacco sheet includes contacting a tobacco raw material with water to separate them into an aqueous extract and an insoluble tobacco residue, selectively reducing anions contained in the aqueous extract to provide a low-anion liquid, adding an acid to the low-anion liquid to provide a neutralized liquid, and blending pulp to the insoluble tobacco residue to prepare a mixture from which a sheet is made, followed by adding the neutralized liquid to the sheet to provide a tobacco sheet.
