Zusammenfassung:Methods of making undenatured pre-acidified whey protein isolates and protein-fortified beverages incorporating such undenatured pre-acidified whey protein isolates are described. Methods include ultrafiltering a liquid whey composition into a liquid whey protein retentate and a liquid whey permeate, and microfiltering the liquid whey protein retentate into a microfiltered whey protein retentate and a microfiltered whey protein permeate. Methods include reducing a pH of the microfiltered whey protein permeate to a pH of less than 3.8, forming a reduced pH whey protein permeate, and ultrafiltering and diafiltrating the reduced pH whey protein permeate into the undenatured pre-acidified whey protein isolate. Methods include optionally nanofiltering the undenatured pre-acidified whey protein isolate.
