Abstract
The present invention relates to a process for producing a substantially pure &kgr;-casein macropeptide fraction having nutraceutical properties by contacting whey with an anion exchanger to yield a bound whey protein fraction enriched in &kgr;-casein macropeptide fraction and an unbound whey protein fraction depleted in &kgr;-casein macropeptide; and contacting the bound whey protein fraction enriched in &kgr;-casein macropeptide fraction with an adsorbent, specifically an immobilized metal affinity adsorbent, to separate out the substantially pure &kgr;-casein macropeptide fraction.
