Document Type and Number:
Japanese Patent JP7141774
Kind Code:
B2
Abstract:
Provided is a method for preparing poplar xylooligosaccharide by means of a bio-enzyme in cooperation with physicochemical purification, comprising: subjecting a pre-hydrolyzed solution of poplar in hot water to a centrifugal treatment, then subjecting a supernate therefrom to successive treatments with calcium hydroxide, laccase in cooperation with xylanase and activated carbon adsorption, so as to obtain the xylooligosaccharide purified liquid.
