Method for producing purified soybean oligosaccharide solution

摘要

A process for producing a purified soybean oligosaccharide solution according to the present invention is a process for producing a purified soybean oligosaccharide solution from soybean and / or soybean processed matter, which comprises soybean and / or soybean processed matter, a polar organic solvent and water (1) a step of obtaining a soybean oligosaccharide liquid containing a water-containing polar organic solvent by removing the produced precipitate after mixing with a water-containing polar organic solvent, a step (1) of removing the polar organic solvent from the soybean oligosaccharide liquid , A step (2) of obtaining a soybean oligosaccharide suspension, a step (3) of mixing cellulase with the soybean oligosaccharide suspension to obtain a cellulase-treated soybean oligosaccharide suspension, And a step (4) of obtaining a purified soybean oligosaccharide solution by solid-liquid separation of the sugar suspension.
