METHOD FOR PRODUCING SUGAR, SUGAR, AND DEVICE FOR PRODUCING SUGAR
Document Type and Number:
WIPO Patent Application WO/2012/128300
Kind Code:
A1
Abstract:
Provided are a method for producing a sugar at a high productivity using a cellulose-based biomass as a starting material, a sugar obtained by the production method, and a device for producing the sugar. The method according to the present invention for producing a sugar using a cellulose-based biomass as a starting material is characterized by comprising: a mixing step for obtaining a mixture which contains the cellulose-based biomass, a hydrophilic polymer and water; a dividing step for applying a shear force to the mixture to divide the cellulose-based biomass; a saccharifying step for saccharifying the divided cellulose-based biomass with a cellulose-digesting enzyme; a first separation step for adding an inorganic salt to the mixture having been treated in the saccharifying step and thus separating the mixture into a sugar solution and a first residue; and a reusing step for adding at least a portion of the first residue to the mixture in the aforesaid mixing step.
