FIELD: food industry.
SUBSTANCE: method includes the process of hydrolysis of hydrolysable cellulose contained in vegetal raw material and production of glucose in an organic solvent wherein a complex acid catalyst is dissolved and the process of saccharide extraction by way of the reaction mixture separation (after the hydrolysis process completion) into a liquid fraction including the complex acid catalyst and the organic solvent and a solid fraction including saccharide. The organic solvent is represented by an alcohol with 6-10 carbon atoms.
EFFECT: reduction of the quantity of the complex acid applied as the cellulose hydrolysis catalyst, increase of the process energy efficiency factor.
