Cluster Dextrin® (Highly Branched Cyclic Dextrin) is a new type of dextrin that is produced from amylopectin via a cyclization reaction of a branching enzyme (BE, 1,4-α-D-glucan: 1,4-α-D-glucan 6-α-D-(1,4-α-D-glucano)-transferase, EC 2.4.1.18). Ezaki Glico has successfully achieved industrial production of Cluster Dextrin® by applying its unique technology in enzymology. Glico has taken out substance and production patents for this product in Japan, the USA, and Europe. In addition, Glico obtained Self Affirmed GRAS (Generally Recognized as Safe) status for Cluster Dextrin® in July 2008.
