Partial replacement of NaCN with WPC also enhanced flocculation or flocs network causing larger particle size of droplets. Due to different molecular structure and different aggregation behavior, the adsorbed layer of caseinate (flexible proteins) and whey proteins (globular proteins) on the droplets would exhibit different arrangements in terms of the thickness and density of the adsorbed layer as well as the distance between the hydrophilic residues, or between the hydrophilic residue and hydrophobic residue
