METHOD FOR SUGAR SOLUTION PRODUCTION Russian patent published in 2016 - IPC C13K1/04 C12P19/14 

FIELD: food industry.

SUBSTANCE: according to the proposed method for production of liquid sugar using cellulose-containing biomass as raw material there is a hydrolysis of cellulose-containing biomass for producing an aqueous solution of sugar and its filtering through an ultrafilter membrane. Membrane has a threshold of molecular weight cutoff from 600 to 2,000 to remove fermentation inhibitors onto the permeate side and collect sugar liquid from the side of supply. Fermentation inhibitors contain one or more substances selected from a group consisting of cumaric acid, ferulic acid and 2,3-dihydrobenzofuran.

EFFECT: method ensures production of sugar liquid with minimum content of fermentation inhibitors.
