Abstract

In one aspect, the invention provides a method of extracting arabinoxylan 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 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; 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. In a further aspect, the invention provides methods of preparing novel arabinoxylan esters and ethers. Still further, the invention provides novel arabinoxylan esters and ethers.
