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 hydrolysate mixture of sugars characterized by a ratio of fructose to mannose of at least 0.4, wherein said hydrolysate mixture further comprises hydroxymethylfurfural.
A hydrolysate mixture of sugars characterized by a ratio of fructose to xylose of at least 0.4, wherein said hydrolysate mixture further comprises hydroxymethylfurfural.
A hydrolysate mixture of sugars characterized by a ratio of fructose to galactose of at least 0.3, wherein said hydrolysate mixture further comprises hydroxymethylfurfural.
A hydrolysate mixture of sugars characterized by a ratio of fructose to arabinose of at least 1.0, wherein said hydrolysate mixture further comprises hydroxymethylfurfural.
A hydrolysate mixture of sugars characterized by a ratio of fructose to total monomeric sugars of at least 0.023, wherein said hydrolysate mixture further comprises hydroxymethylfurfural.
An acid hydrolysate mixture of sugars characterized by a ratio of fructose to mannose of at least 0.4, wherein the acid hydrolysate mixture of sugars was produced by contacting a partially processed crop with an acid.
