Immobilized maltogenic alpha-amylase and its use in manufacture of a syrup rich in maltose

摘要

Immobilized maltogenic alpha -amylase is new and comprises being adsorbed onto particles onto a porous support. Independent claims are also included for the following: (1) a process for the manufacture of a maltose rich syrup comprising: (a) liquefying starch milk; (b) saccharifying the starch milk liquefied in the presence of a beta -amylase and at least a debranching enzyme e.g. pullulanases and isoamylases; (c) contacting the liquefied and saccharified starch milk with an immobilized maltogenic alpha -amylase to obtain the maltose rich syrup; (2) a process for the manufacture of a maltose rich syrup comprising steps (a) and (b) and further comprising: (i) molecular filtering the starch milk to recover a maltose enriched fraction and a maltose depleted fraction; (ii) contacting the maltose enriched fraction with an immobilized maltogenic alpha -amylase to obtain a maltose rich syrup; (3) a process for the manufacture of crystallized maltose comprising crystallizing the maltose rich syrup; (4) a process for the manufacture of a maltitol by hydrogenation of the maltose rich syrup; and (5) a manufacture process of crystallized maltitol by crystallizing the maltitol rich syrup.
