Abstract:
A method for producing a heat-irreversibly coagulated glucan sheet, comprising the steps of:(a) providing a dispersion medium of an aqueous leaf tobacco extract prepared from 20 to 200 parts by weight of leaf tobacco in 1000 parts by weight of water or its concentrate concentrated by 1 to 70% by weight; (b) providing powder of heat-irreversibly coagulating glucan in a concentration of from 1 to 20% by weight of said extract or concentrate; (c) providing a dispersion interference-preventing agent comprising an organic acid in an amount of 30% by weight or less of said extract or concentrate; (d) preparing a mixture by adding said powder of the glucan and said dispersion interference-preventing agent to said dispersion medium; (e) stirring said mixture to disperse the powder of said glucan into said dispersion medium, thereby forming a slurry having an increased viscosity; (f) forming said slurry into a sheet form; and (g) heating and coagulating the resultant sheet formed body.
