Abstract
A nanofilter membrane is used to filter the outflow of a food processing stream which begins with a starch slurry and ends with a glucose syrup which in its preferred form is about 95% dextrose and 5% di- and trisaccharides. The nanofilter membrane is able to pass the dextrose while retaining the di- and trisaccharides. As a result, the invention is able to produce substantially pure dextrose, with purity in a range which is well over 99%.
