ISOLATION OF OLIGOSACCHARIDES FROM BIOMASS

摘要

A process for isolating substantially pure oligosaccharide from an aqueous solution of oligosaccharide such as the aqueous extract of biomass by purifying the oligosaccharide in solution, preferably by bleaching, and then separating the oligosaccharide from associated aqueous extract components, preferably by ultrafiltration. The process may be advantageously utilized to produce macromolecular polysaccharides with a well defined molecular weight distribution and with known characteristics, such as water or alkaline solubility.
