Method for treatment of corn hulls
First Claim
1. A method for treating corn hulls to obtain a cellulose fraction, a hemicellulose fraction and a noncarbohydrate fraction comprising treating corn hulls with a sufficient amount of alkali to hydrolyze the corn hulls to affect liberation of the hemicellulose fraction so that it may be solubilized in water and to solubilize the noncarbohydrate fraction, recovering a hemicellulose fraction, an organic solvent extract of the noncarbohydrate fraction and an insoluble residue comprising the cellulose fraction.

Abstract
Corn hulls are subjected to a treatment to obtain three fractions therefrom comprising a cellulosic fraction, a hemicellulose fraction and a noncarbohydrate fraction. The noncarbohydrate fraction is characterized as being an organic solvent extract comprising at least about 15 percent of the dry weight of the corn hulls and containing above about 10 percent by weight ferulic acid.
