Whey protein concentrate, its preparation and its use

摘要

The invention pertains to process for manufacturing whey protein concentrate (WPC) from whey, said process involving (a) providing acidified whey; (b) increasing the pH of said acidified whey using one or more carbonate salt(s), preceded and/or followed by ultrafiltration, and (c) subjecting the ultraf&idigr;ltered carbonate-containing whey to spray drying. A WPC is provided having improved functional properties, particularly increased gel strength and reduced salt sensitivity (i.e. meaning that the functional properties of the WPC are affected by salt to a lesser extent).
