METHODS OF EXTRACTING CASEIN FRACTIONS FROM MILK AND CASEINATES AND PRODUCTION OF NOVEL PRODUCTS

摘要

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 alpha s-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.
