Abstract
A method comprising: (a) providing a partially processed sucrose crop product containing at least 2% optionally at least 5% of the sucrose content of said crop at harvest on a dry solids basis, cellulose and lignin; (b) hydrolyzing said partially processed crop product with HCl to produce an acid hydrolyzate stream and a lignin stream; and (c) de-acidifying said hydrolyzate stream to produce a de-acidified sugar solution and an HCl recovery stream. Additional, methods, systems and sugar mixtures are also disclosed.

A method comprising
- (a) providing a partially processed sucrose crop product containing at least 2%, optionally at least 5% of the sucrose content of said crop at harvest on a dry solids basis, cellulose and lignin;
- (b) hydrolyzing said partially processed crop product with an acid to produce an acid hydrolyzate stream and a lignin stream;
- and
- (c) de-acidifying said hydrolyzate stream in the presence of an S1 solvent to produce a de-acidified sugar solution and an acid recovery stream.
A system comprising:
- (a) a sucrose extraction module adapted to separate sucrose from a received crop to produce a partially processed crop product containing residual sucrose and a raw juice comprising sucrose;
- (b) a hydrolysis module which receives said partially processed crop and brings it into contact with a concentrated acid to produce an acid hydrolyzate and residual lignin;
- and
- (c) an acid recovery module which receives said acid hydrolyzate and separates it to produce an acid recovery stream and a de-acidified hydrolyzate.
A hydrolysate mixture of sugars characterized by a ratio of fructose to mannose of at least 0.4.
A hydrolysate mixture of sugars characterized by a ratio of fructose to xylose of at least 0.4.
A hydrolysate mixture of sugars characterized by a ratio of fructose to galactose of at least 0.3.
A hydrolysate mixture of sugars characterized by a ratio of fructose to arabinose of at least 1.0.
