Patent ID: 8603560

Claim:
A milk protein fraction, having the following characteristics: a protein content of greater than 90%, a mineral salt content of less than 1%, a fat content of less than 1%, a lactose content of less than 1%, a moisture content of less than 5%, a lactoferrin content of between 2% and 80%, a solution of the milk protein fraction with a concentration of 2% has a pH of between 6 and 7.5, a UV-visible spectrophotometric purity defined by an 0.06≦OD 412 /OD 280 ratio<0.15, contains between 1% and 90% of proteins having an isoelectric point greater than or equal to 8, the percentages being given by weight relative to the weight of dry matter content of the milk fraction, and wherein the milk protein fraction has a lactoperoxydase activity greater than or equal to 120 ABTS units per mg.
