Latest Patents

Masatoshi Sano holds a patent for a process titled "Process for producing highly pure rhamnose from gum arabic." This patent outlines a method that involves partially hydrolyzing gum arabic in an aqueous solution of a mineral acid, followed by neutralization and condensation of the hydrolyzate. The process results in an aqueous solution containing 40 to 70% by weight of organic substances. By adding a polar organic solvent, Sano's method precipitates an insolubilized substance, which is then removed to yield a solution rich in monosaccharides. The final steps involve using strongly cationic ion-exchanging resin-chromatography and activated carbon to obtain highly pure rhamnose.
