Cellobiuronic acid may be prepared by hydrolysis of gellan. The method provides embodiments expressed in terms of amounts of cellobiuronic acid produced, amounts of gellan gum hydrolyzed and amounts of cellobiuronic acid present in fractions of a hydrolysate The method may further include isolation of a separated fraction of the hydrolysate where the separated fraction comprises cellobiuronic acid. 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.
