Abstract
A method including: (a) selectively reacting a first sugar in a mixture which includes at least one second sugar to form a product mixture comprising a product of said first sugar; (b) separating said product of said first sugar from said product mixture; and (c) separating at least one of said at least one second sugar from said product mixture.
Claims22
A lignocellulosic hydrolysate comprising:
- (a) at least 60% xylose by weight relative to total sugar concentration;
