A novel method is described for selectively precipitating casein fractions from skimmed milk or caseinates by the addition of calcium salt at alkaline pH. In particular, the invention describes a process with allows casein to be fractionated to yield two fractions of alphas-casein and beta-casein and, for the first time, preparation of material highly enriched in kappa-casein. The kappa-casein can be further processed to manufacture pure CMP, which can be used as nutrition for sufferers of the metabolic disease phenyalketonuria. |
