Abstract
This invention is directed to a process for producing an immunoglobulin enriched whey protein fraction from whey protein solutions. More particularly, it relates to the production of a whey protein fraction enriched in immunoglobulin, and optionally a whey protein isolate, using a cation exchanger under selected conditions. The selected conditions require overloading the cation exchanger with potentially absorbable protein which causes the exchanger to adsorb preferentially whey proteins other than immunoglobulin. The invention is also directed to the products produced by the process of the invention.
