title: [Effect of thermolability of milk proteins on ion distribution in two-phase system of skimmed milk-water-salt].
abstract: Significant increases in concentrations of bivalent metals (Ca2+, Mg2+, and Cd2+) in the protein phase were observed after acidification (pH 4.7) of skimmed milk preheated at 95 degrees C for 90 min. The increase was caused by denaturation of milk whey proteins and formation of protein-protein and protein-carbohydrate aggregates. Preheating did not influence the distribution of nitrate ions in the two-phase system.
