  • Corn fiber for the production of advanced chemicals and materials: separation of monosaccharides and methods thereof
    Patent number: 6352845
    Abstract: In one aspect, the invention provides methods of obtaining at least one monosaccharide from corn fiber the method comprises the steps of: (a) heating an aqueous mixture of corn fiber and a liquid; (b) contacting the mixture of step (a) with a protease enzyme, thereby providing a proteolyzed corn fiber and a liquid; (c) separating the liquid from the proteolyzed corn fiber; (d) contacting the proteolyzed corn fiber at least once with an alkaline extractant, thereby providing an insoluble cellulose material and a liquid comprising arabinoxylan; (e) separating the insoluble cellulose material from the liquid comprising arabinoxylan; (f) reducing the volume of the liquid comprising arabinoxylan by removing excess alkaline extractant, thereby providing a concentrated liquid comprising from about 10 to about 50% solids, wherein the solids comprise arabinoxylan; and (g) hydrolyzing the arabinoxylan from step (f) in the presence of a catalyst and a solvent, thereby providing a mixture comprising at least one monosacc
