Composition and Properties of Submicellar Casein Complexes in Colloidal Phosphate-Free Skimmilk

Abstract

Colloidal phosphate-free milks prepared from raw or heated (80 C for 30 min) skimmilk by adjustment to pH 4.9 or addition of ethylenediaminetetraacetate followed by dialysis were similar in total and dialyzable nitrogen, calcium, and phosphate. A small amount of inorganic phosphate was not dialyzable and 20 to 25% of the original skimmilk nondialyzable calcium was retained.
