A method to prepare syrups with a high degree of conver-sion

摘要

A method for production of high conversion syrup wherein a liquefied starch is hydrolyzed with an alpha -amylase covalently immobilized inside a carrier substance. Use of the novel immobilized alpha -amylase provides a single step reaction wherein the liquefied starch solution is converted into a high conversion syrup through the action of a single enzyme. Preferred alpha -amylases are acid stable alpha -amylases derived from Aspergillus and a well suited acid stable alpha -amylase is derived from Aspergillus niger strain DSM 2761.
