Process for producing a syrup rich in maltose

摘要

A process for the manufacture of a maltose rich syrup is new and comprises liquefying and saccharifying a starch milk in the presence of beta -amylase and at lest one debranching enzyme e.g. pullulanases and/or isoamylases, filtering the solution and recovering the maltose and glucose enriched fractions and contacting the maltose rich solution with a maltogenic alpha -amylase to obtain the maltose rich syrup. Independent claims are also included for the following: (1) manufacture of a maltose rich syrup comprising: (a) liquefaction of a starch milk; (b) saccharification of the starch milk in the presence of a beta -amylase; (c) filtering the starch milk to recover maltose and glucose and maltose enriched fractions; (d) contacting the maltose rich fraction with a maltogenic alpha -amylase and at least one debranching enzyme e.g. pullulanases and/or isoamylases for obtaining the maltose rich syrup; and (2) the manufacture of crystallized maltose comprising crystallizing maltose rich syrup.
