<p>A method of preparing a milk protein isolate by ultrafiltration of a milk derivative containing dissolved milk proteins, comprising ultrafiltration of a non-preheated or at most low pasteurized skim milk or mixture of skim milk and a whey containing solution at a pH ranging from 3 to 4, followed by diafiltration of the retentate, then increasing the pH to a value substantially within the neutral range, at which pH ultrafiltration is continued until a solids content in the retentate of at least 15% and in particular about 20%.</p> |
