CambiaLabs IP – Preparation of Cellobiuronic Acid from Polysaccharide

A preferred embodiment of the method includes hydrolyzing gellan gum with a protic acid under reaction conditions that convert at least 95 wt% of the gellan gum to a hydrolysate comprised of cellobiuronic acid and monosaccharides and isolating a separated fraction of the hydrolysate where cellobiuronic acid comprises at least a 95 wt% of saccharides in the separated fraction. Cellobiuronic acid may be prepared by hydrolysis of gellan gum. The method may further include isolation of a separated fraction of the hydrolysate where the separated fraction comprises cellobiuronic acid. Issued in the United States as Patent Number 6,268,493. Issued in Australia as Patent Number 764652.
