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) processing a crop containing a content of sucrose at harvest to produce a partially processed sucrose crop product containing at least 2% 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 acid to produce an acid hydrolyzate stream and a lignin stream;
- and
- (c) de-acidifying said hydrolyzate stream to produce a de-acidified sugar solution, the de-acidifying comprising extracting said hydrolyzate stream with a first extractant comprising a first solvent to produce an acid-carrying first extract and the de-acidified sugar solution.
