Abstract

ABSTRACT Sodium phytate was added to milk with and without the addition of Fe or Zn and the solubility of the endogenous Ca and added Fe or Zn was not affected. However, when these experiments were repeated with a model system containing CaCl 2 at the same calcium concentration as milk, the addition of Na phytate caused a significant precipitation of each of these minerals. These results suggest that milk exerts a protective effect on the phytate induced precipitation of these minerals and thus their potential bioavailability.
