PROBLEM TO BE SOLVED: To provide a method for extracting at least one protein present in milk, the protein showing an affinity for calcium ions in complexes or free, in the milk.SOLUTION: A method for extracting a protein includes the steps of (a) freeing the protein by precipitating calcium compounds obtained by contact of a milk with a soluble salt, whose anion is chosen for its capacity to form the insoluble calcium compounds in such a medium, in order to thus obtain a liquid phase that is enriched with the protein, (b) separating the protein-enriched liquid phase from the calcium compound precipitate, the liquid phase being moreover separated into a lipid phase and a non-lipid aqueous phase containing the protein, and (c) collecting the aqueous non-lipid phase containing the protein. |
