Abstract
A sugar mixture comprising: monosaccharides; oligosaccharides in a ratio ≧0.06 to total saccharides; disaccharides in a ratio to total saccharides ≧0.05; pentose in a ratio to total saccharides ≧0.05; at least one alpha-bonded di-glucose; and at least one beta-bonded di-glucose. Also disclosed are methods to make and/or use such mixtures.
Claims27
A de-acidified and de-salted sugar mixture, the de-acidified and de-salted sugar mixture comprising monosaccharide hydrolysates;
- (i) higher oligosaccharide hydrolysates comprising three or more sugar units;
- (ii) a ratio of disaccharide hydrolysates to total saccharides of ≧0.05 on a weight by weight basis;
- (iii) a ratio of pentose to total saccharides of ≧0.05 on a weight by weight basis;
- (iv) at least one alpha-bonded di-glucose;
- (v) at least one beta-bonded di-glucose;
- and
- (vi) a mineral acid to carbohydrate ratio of less than 0.01 on a weight by weight basis.
A de-acidified and de-salted sugar mixture, the de-acidified and de-salted sugar mixture comprising monosaccharide hydrolysates and oligosaccharide hydrolysates, wherein the oligosaccharide hydrolysates to total carbohydrate in the de-acidified and de-salted sugar mixture has a ratio of less than 0.15 on a weight by weight basis;
- wherein the de-acidified and de-salted sugar mixture is further characterized by having:
- (i) higher oligosaccharide hydrolysates comprising three or more sugar units;
- (ii) a ratio of disaccharide hydrolysates to total saccharides of ≧0.05 on a weight by weight basis;
- (iii) a ratio of pentose to total saccharides of ≧0.05 on a weight by weight basis;
- (iv) at least one alpha-bonded di-glucose;
- (v) at least one beta-bonded di-glucose;
- and
- (vi) sulfuric acid to carbohydrate ratio of less than 0.01 on a weight by weight basis.
