Abstract
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 α-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.
Claims19
A method comprising:
- providing a corn fraction, said corn fraction having been prepared from a dry-milled corn product;
- subjecting said corn fraction to hydrolysis under conditions suitable to result in a mixture of malto-oligosaccharides;
- and
- recovering said mixture of malto-oligosaccharides, the mixture recovered having a DE of at most 70.
A method comprising:
- dry milling corn to form a corn product:
- separating germ and fiber to result in a corn fraction from which at least substantially all of said germ and fiber had been removed;
- subjecting said corn fraction to enzymatically catalyzed hydrolysis under conditions suitable to result in a mixture of malto-oligosaccharides;
- inactivating said α-amylase enzyme;
- recovering said malto-oligosaccharide mixture from remaining solids, said malto-oligosaccharide mixture having a DE of at most 70;
- and
- purifying said malto-oligosaccharide mixture.
A mixture of malto-oligosaccharides prepared by a method comprising:
- providing a corn fraction, said corn fraction having been prepared from a dry-milled corn product;
- subjecting said corn fraction to hydrolysis under conditions suitable to result in a mixture of malto-oligosaccharides;
- and
- recovering said mixture of malto-oligosaccharides, the mixture recovered having a DE of at most 70.
