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 adsorbable 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.
Cette invention concerne un procédé de production d'une fraction enrichie en immunoglobulines à partir de solutions de protéines de petit lait. Plus spécifiquement, cette invention concerne la production d'une fraction protéinique de petit lait enrichie en immunoglobulines, et éventuellement un isolat de protéines de petit lait, au moyen d'un échangeur cationique dans des conditions choisies. Ces conditions nécessitent la surcharge de l'échangeur cationique avec des protéines à potentiel adsorbable qui provoquent l'adsorption par l'échangeur des protéines de petit lait de préférence aux immunoglobulines. L'invention concerne également les produits obtenus par ce procédé.
