Abstract:
A method of producing a maltose syrup, comprising the steps of:(a) subjecting a liquefied starch solution to saccharification, which comprises more than one enzymatic saccharification stage, in the presence of a maltogenic alpha-amylase, and a fungal alpha-amylase;(b) subjecting the saccharification liquor from one of the saccharification stages to a microfiltration step;(c) subjecting the permeate of the microfiltration step to an ultrafiltration step;(d) re-circulating the retentate from the ultrafiltration step to a saccharification stage of step (a) wherein the content of maltose in the reaction mixture in the saccharification stage equals the content of maltose in the retentate; and(e) recovering the permeate of the ultrafiltration step which comprises maltose.
