An isoamylase having improved heat resistance and an industrial method for producing maltose from starch. The isoamylase is an isoamylase consisting of the amino acid sequence represented by SEQ ID NO: 1 or an isoamylase resulting from deletion, substitution, or insertion of one to several amino acid residues in the amino acid sequence represented by SEQ ID NO: 1, wherein at least valine at amino acid number 515 and methionine at amino acid number 570 are mutated to other amino acids.

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.

Disclosed is a method for preparing a mixture of malto-oligosaccharides. Generally, a dry-milled corn fraction, such as a corn flour from which germ and fiber have been removed, is subjected to hydrolysis, typically catalyzed with acid or an enzyme such as an -amylase enzyme, under conditions suitable to form a mixture of malto-oligosaccharides. A gluten fraction is removed and the enzyme is inactivated, such as with heat. The mixture of malto-oligosaccharides then may be recovered from remaining solids and purified.

The invention relates to a process for separating one or more carbohydrate from a composition wherein separating is done through radial chromatography. Preferably, the invention relates to a process for separating at least two carbohydrates from a composition wherein separating is done through radial chromatography, and wherein each of the at least two carbohydrates are collected in a purified form. The present invention relates to the use of radial chromatography for the separation of one or more carbohydrate from a composition and obtaining the one or more carbohydrate in a purified form.
