Patent ID: 7670811

Claim:
A process of elongating the chain length of isomalto-oligosaccharides, wherein said process comprises: (a) enzymatically converting a malto-oligosaccharide syrup with one or more isomalto-oligosaccharide-producing enzymes into a carbohydrate syrup containing isomalto-oligosaccharides; (b) preparing a solution containing the isomalto-oligosaccharides by adding sucrose to the carbohydrate syrup from (a), wherein the ratio by volume (v/v) of isomalto-oligosaccharides in the carbohydrate syrup from (a) to sucrose in said solution is in the range of from about 50:50 (v/v) to about 30:70 (v/v); (c) adding at least one glucansucrase to said carbohydrate syrup or to said solution in (b); and (d) in the presence of said glucansucrase, reacting the sucrose with the isomalto-oligosaccharides in the solution, thereby producing a syrupy mixture wherein said syrupy mixture contains isomalto-oligosaccharides having an elongated chain length.
