PURPOSE:To prepare a salt, consisting essentially of cacium, and having a good absorption rate of calcium, by acidifying a solution of a milky raw material, removing th resultant coagulum from the solution, and treating the resultant mother liquor with an alkali. CONSTITUTION:A solution of cow's milk or another milky raw material is acidified with an acid or subjected to the lactic acid fermentation to 3.0-5.5pH, preferably 4.0-5.0pH, and the resultant coagulum is removed to give a mother liquor. An alkali is then added to the mother liquor and neutralized at 5.0- 8.0pH, preferably 6.0-7.0pH, to precipitate and separate the resultant salt, which is further concentrated or dried. |
