ABSTRACT:
A process for the selective and quantitative elimination of lactoglobulins from a starting material containing whey proteins, wherein the starting material is brought into contact with a strongly basic type anion exchanger, the pH of the starting material being between 4 and 6 when the ash content of the starting material is between 0 and at most 1% by weight, and between 6 and 8 when the ash content is between more than 1% and 3% by weight, so as to retain the lactoglobulins selectively and quantitatively on the anion exchanger, the anion exchanger on which the lactoglobulins are retained is separated from the remainder of the starting material and the remainder, free from lactoglobulins, is collected.
