Abstract
The present invention pertains to a method for isolating osteopontin from a milk-derived feed containing caseino macropeptide and/or free beta casein, such as e.g. a feed based on milk serum or sweet whey. Particularly, the present method involves the use of a narrow window of pH and specific conductance of the milk-derived feed, which surprisingly has proven to provide a very efficient isolation of osteopontin from chemically complex feeds.
