| abstract |
The present invention relates to a method for preparing enzymatically highly branched-amylose and amylopectin cluster. Alpha-glucanotransferase or branching enzyme hydrolyzes the linkage of the segment between amylopectin clusters in starch, producing amylopectin cluster, and simultaneously branching enzyme attaches the branched side-chain to amylose, producing branched amylose, and subsequently treating the amylopectin cluster or branched amylose with maltogenic amylase for cleaving long side chain into short side chain and for transferring glucose to the side chain, generating highly branched amylopectin cluster, highly branched amylose or branched oligosaccharide from starch effectively. |
