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