摘要： Disclosed herein is a process for producing highly pure rhamnose from gum arabic, which the process comprises after partially hydrolyzing gum arabic in an aqueous solution of a mineral acid, neutralyzing and condensing the liquid hydrolyzate, thereby obtaining an aqueous solution containing from 40 to 70% by weight of organic substances, adding a polar organic solvent in an amount of from 5 to 20 times by volume of the amount of the aqueous solution, thereby precipitating an insolubilized substance, removing the insolubilized substance from a mixture of the aqueous solution and the polar organic solvent, removing the polar organic solvent from the mixture, thereby obtaining an aqueous solution containing monosaccharides formed by the hydrolysis of gum arabic, and subjecting the thus obtained aqueous solution to strongly cationic ion-exchanging resin-chromatography and then to a method of adsorption and separation by using activated carbon, thereby obtaining the highly pure rhamnose from the aqueous solution.
