FIELD: technological processes.
SUBSTANCE: process for the production of sugars from biomass including at least one polysaccharide. Method comprises putting a biomass in contact with an aqueous solution of at least one organic acid having from 1 to 6 carbon atoms, preferably from 1 to 3 carbon atoms. pH of said aqueous solution being ranging from 0.6 to 1.6, preferably ranging from 0.9 to 1.3.
EFFECT: invention makes it possible to increase yield of sugars from biomass with simultaneous low formation of by-products, for example furfural or hydroxymethylfurfural.
