Process for producing bovine lactoferrin in high purity

摘要: A process for producing bovine lactoferrin in high purity form raw milk-materials containing skim milk or whey originated cow's which comprises: adsoption step wherein said materials are contacted, at a temperature between 0°-60° C., with weakly acidic cation-exchanger includes carboxymethyl groups as ion exchanging and has haemoglobin adsorption property more than 3.5 g/100 ml; rinsing exchanger is washed water to remove substances other those adsorbed exchanger; desorption the desorbed therefrom solution of one salts thereby yield highly purified without deterirating materials. Said can be carried out single stage produce 80% total proteins recovered, two attain 98% purity.
