Abstract

A method including: (a) selectively reacting a first sugar in a mixture which includes at least one second sugar to form a product mixture comprising a product of said first sugar; (b) separating said product of said first sugar from said product mixture; and (c) separating at least one of said at least one second sugar from said product mixture.

Claims

1. A sugar composition comprising:

(a) glucose;

(b) at least one additional monomeric sugar;

(c) an alpha-bonded diglucose or a beta-bonded diglucose; and

(d) an oligosaccharide comprising a xylose-containing oligomer.

2. The sugar composition of claim 1, wherein:

the at least one additional monomeric sugar is xylose;

the alpha-bonded diglucose is maltose, isomaltose, trehalose, or a combination thereof; and

the beta-bonded diglucose is gentiobiose, sophorose, cellobiose, or a combination thereof.

3. The sugar composition of claim 2, comprising:

(a) 0.001%-5%, based on the total weight of the composition, of glucose;

(b) 0.01%-20%, based on the total weight of the composition, of xylose;

(c) at least 1000 PPM, based on the total weight of the composition, of the alpha-bonded or beta-bonded diglucose; and

(d) 0.001%-10%, based on the total weight of the composition, of the oligosaccharide.

4. A sugar composition comprising:

(a) a first sugar, wherein the first sugar is glucose; and

(b) a second sugar, wherein the second sugar comprises a mixture of a pentose, a disaccharide, and an oligosaccharide,

wherein;

the pentose is xylose, xylulose, lyxose, ribulose, arabinose, or a combination thereof;

the disaccharide is trehalose, gentiobiose, kojibiose, nigerose, sophorose, laminarobiose, or a combination thereof; and

the oligosaccharide is a xylose-containing oligomer.

5. The sugar composition of claim 4, comprising:

(a) 0.01%-20%, based on the total weight of the composition, of xylose;

(b) 0.001%-40%, based on the total weight of the composition, of the oligosaccharide;

(c) 0.001%-5%, based on the total weight of the composition, of glucose; and

(d) at least 1000 PPM, based on the total weight of the composition, of the alpha-bonded or beta-bonded diglucose.

6. A sugar composition comprising:

(a) 0.01%-20%, based on the total weight of the composition, of xylose;

(b) 0.001%-10%, based on the total weight of the composition, of oligosaccharide, wherein the oligosaccharide comprises a xylose-containing oligomer;

(c) 0.001%-5%, based on the total weight of the composition, of glucose; and

(d) at least 1000 PPM, based on the total weight of the composition, of alpha-bonded or beta-bonded diglucose.
