1. A lignocellulosic composition comprising (on a dry matter basis) cellulose, at least 7.4% by weight hemicellulose, and lignin, wherein said lignocellulosic composition is a solid, and further wherein said lignocellulosic composition comprises:
- (i) lipophilic material at less than 5000 PPM;
(ii) ash at less than 2000 PPM or Ca at less than 2000 PPM;
(iii) pectin at less than 10,000 PPM;
(iv) furfural at less than 2000 PPM; and
(v) at least 10 PPM of a marker selected from the group consisting of;
hydroxy-methyl furfural, products of furfural condensation, products of hydroxy-methyl furfural condensation, color compounds derived from sugar caramelization, levulinic acid, acetic acid, methanol, galacturonic acid, glycerol, organically bound sulfur and acetone.

Abstract
A method comprising: (a) providing a lignocellulosic substrate; (b) contacting said lignocellulosic substrate with an extractant comprising a water-soluble organic solvent to form an extracted substrate and a miscella; (c) removing miscella from said extracted substrate; and (d) hydrolyzing said extracted substrate using a chemically catalyzed process.
