ABSTRACT:
The separation of mono- or disaccharides such as glucose or maltose from polysaccharides such as starch may be effected by passing a mixture of these saccharides through an ultra-filtration membrane whereby the glucose or maltose is separated from the starch. The ultra-filtration membranes which are employed for this purpose will comprise a cross-linked polyurethane composited on a support. As an example of the type of membrane which may be employed, an amine-modified polyepihalohydrin such as epichlorohydrin which has been cross-linked with toluene diisocyanate is composited on a polysulfone. This type of ultra-filtration membrane will permit the use of a relatively high flux with a good separation efficiency.
