Title: Production of substantially pure kappa casein macropeptide

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