| 摘要 |
The invention concerns a process for the manufacture of a starch hydrolysate with high dextrose content comprising the stages of:(a) liquefying a starch milk with the aid of an alpha-amylase so as to obtain a liquefied starch milk;(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;(c) microfiltering the raw saccharified hydrolysate so as to collect a microfiltration permeate and a microfiltration retentate;(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.
