Abstract
The invention concerns a process for the manufacture of a starch hydrolysate with high dextrose content comprising the stages of: PA1 (a) liquefying a starch milk with the aid of an .alpha.-amylase so as to obtain a liquefied starch milk; PA1 (b) saccharifying the liquefied starch milk, with the aid of a glucogenic enzyme, to obtain a raw saccharified hydrolysate having a maximum content of 80% by weight, and preferably 75% by weight; PA1 (c) microfiltering the raw saccharified hydrolysate so as to collect a microfiltration permeate and a microfiltration retentate; PA1 (d) separating the microfiltration permeate by nanofiltration over membranes so as to collect a nanofiltration permeate constituting said starch hydrolysate with high dextrose content and a nanofiltration retentate.
