Title:
METHOD OF PRODUCING SACCHARIDE COMPOSITIONS STARTING WITH BIOMASS
Document Type and Number:
WIPO Patent Application WO/2007/026817
Kind Code:
A1
Abstract:
A method of producing three types of saccharide compositions respectively containing hemicellulose type oligosaccharides, cellulose type oligosaccharides and glucoses, characterized by comprising the steps of successively treating a solid biomass (in particular, a woody biomass) with two or more acid-treatment solutions having different acid concentrations, separating the liquid reaction mixture obtained by each of the treatment steps into the supernatant and the solid matters, treating the thus separated solid matters in the subsequent acid-treatment step, and repeating the procedures in the above steps to thereby separate and recover saccharide compositions of different types by the individual treatment steps.
