Preparation and Suspension Stability of a New Calcium-Fortifier

Abstract:

A new calcium-fortifier（Ca-MPC） prepared from milk protein concentration（MPC） powders and insoluble calcium salts was characterized by confocal laser scanning microscopes and ζ-potential. It was confirmed as the complex of protein and calcium particles. The formation of Ca-MPC was driven by the weak molecular interactions. The differential interaction between protein and calcium particles was further investigated. An improvement on the suspension stability of Ca-MPC was observed when dispersed either in DI-water or protein solution，implying the industrial application as a good resource of calcium-fortifier.
