A method of producing a sugar liquid includes: (A) reacting mannanase with a liquid component obtained by hydrolysis treatment of woody biomass to obtain a saccharified liquid; and (B) filtering the saccharified liquid in Step (A) through a microfiltration membrane and/or ultrafiltration membrane to collect a sugar liquid from a permeate side.

Method of producing sugar liquid

A method of producing a sugar liquid includes a step of filtering a saccharified liquid derived from cellulose-containing biomass, through a nanofiltration membrane and/or reverse osmosis membrane; and a two-step washing step of washing the nanofiltration membrane and/or reverse osmosis membrane after the filtration, with an acid washing liquid and then with an alkali washing liquid; is provided. The method of producing a sugar liquid in which a cellulose-derived sugar liquid is processed through a nanofiltration membrane and/or reverse osmosis membrane is/are effectively washed in a contaminated separation membrane(s).

Method of producing sugar solution

A device that produces a sugar solution from cellulose-containing biomass includes: a horizontal reaction tank that includes a stirring shaft provided along a horizontal direction in the horizontal reaction tank and a stirring blade provided to the stirring shaft, the horizontal reaction tank being configured to obtain a saccharified slurry by reacting the cellulose-containing biomass with a saccharification enzyme by stirring the cellulose-containing biomass and the saccharification enzyme; a vertical reaction tank configured to obtain a saccharified liquid by saccharifying the saccharified slurry; a saccharified slurry feed line that connects the horizontal reaction tank and the vertical reaction tank; and a warming part provided around the horizontal reaction tank or on a wall surface of the horizontal reaction tank and heats the horizontal reaction tank.

Device that produces sugar solution and method of producing sugar solution

A method of producing a sugar liquid includes filtering a cellulose-derived sugar liquid through one or more separation membranes selected from the group consisting of an ultrafiltration membrane, a nanofiltration membrane and a reverse osmosis membrane and washing the separation membrane(s) after filtration with washing water containing an alkaline substance and an aromatic compound at 10&#xb0; C. or more and less than 50&#xb0; C.

A method for producing a purified soybean oligosaccharide liquid according to the present invention is a method for producing a purified soybean oligosaccharide liquid from a soybean and/or a processed soybean product, comprising: the step (1) of mixing the soybean and/or the processed soybean product with a water-containing polar organic solvent that contains a polar organic solvent and water and then removing a generated precipitate to obtain a soybean oligosaccharide liquid that contains the water-containing polar organic solvent; the step (2) of removing the polar organic solvent from the soybean oligosaccharide liquid to obtain a soybean oligosaccharide suspension; the step (3) of mixing the soybean oligosaccharide suspension with cellulase to obtain a cellulase-treated soybean oligosaccharide suspension; and the step (4) of subjecting the cellulase-treated soybean oligosaccharide suspension to solid-liquid separation to obtain a purified soybean oligosaccharide liquid.
