Nanocarriers, Films and Composites Based on Milk Proteins

The dominant milk proteins, caseins are similar in structure and found in milk as nanoparticles called micelle. Casein micelles (300-600 nm) are composed of several thousand molecules, bonded via calcium phosphate nanoclusters. All other proteins present in milk are grouped together and termed whey proteins. The primary whey protein in cow milk is β-lactoglobulin. Here we firstly review the chemistry of caseins and whey proteins including presented models and theories for the structure of casein micelles.
