Abstract
Dextrose and dextrins are obtained from protein-containing starch products by subjecting the starch product to an incomplete or complete acid or enzymatic hydrolysis or a combination of both types of hydrolysis and then circulating the hydrolysate containing a low viscosity sugar solution and water-soluble high molecular proteins through an ultrafilter to separate the proteins from the sugar solution whereupon the dextrose or, in case of incomplete hydrolysis, the dextrins are recovered from the filtrate obtained in the ultrafilter.
Claims12
A process for obtaining dextrose and dextrins from a protein-containing starch product comprising
- subjecting the starch product to an incomplete or complete acid or enzymatic hydrolysis or a combination of both types of hydrolysis, then circulating the hydrolyzate containing a low viscosity sugar solution and water soluble high molecular proteins through an ultrafilter to separate the proteins from the sugar solution.
- and separately recovering the high molecular soluble protein from the filtrate of the ultrafiltration followed by subjecting it to spray-drying to obtain a high protein product useful as human food or animal feed,
- while recovering the dextrose or, in case of incomplete hydrolysis, the dextrins from the sugar solution obtained as the filter residue.
