| 摘要 |
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. |
