This invention concerns a method for extracting at least one protein pres ent in milk, the said protein showing an affinity for calcium ions in comple xes or free, in the said milk. It comprises the following steps: a) freeing the protein by precipitating the calcium compounds obtained by contact of th e milk with a soluble salt, whose anion is chosen for its capacity to form t he said insoluble calcium compounds in such a medium, in order to thus obtai n a liquid phases that is enriched with the protein, b) separation of the en riched liquid phase into the protein precipitate with the calcium compound, the said liquid phase being moreover separated into a lipid phase and a non- lipid aqueous phase comprising the protein and c) collection of the aqueous non-lipid phase comprising the protein.
