1. A method for preparing a purified hemicellulose composition comprising:

providing a lignocellulosic biomass;

combining the lignocellulosic biomass with water;

activating the lignocellulosic biomass and water using conditions comprising a temperature and a pressure to form an activated cellulose stream;

washing the activated cellulose stream to form a washed activated cellulose stream and a soluble extract, wherein the soluble extract comprises hemicellulose; and

purifying the soluble extract to obtain a hemicellulose composition comprising:

(a) about 82% to about 92% by dry weight of xylan, wherein said xylan comprises about 70% to about 99% of arabinoxylan;

(b) about 8% to about 9% by dry weight of xylo-oligosaccharide; and
