Abstract:
A method of obtaining at least one monosaccharide from corn fiber, comprising 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 monosaccharide, wherein both steps (d) and (e) are conducted at or above about 60Â° C., thereby providing a derivatizable cellulose material.
