Sodium caseinate is a protein made from casein that acts as an emulsifier. It is composed of protein, fat, calcium, sodium, lactose and others. Sodium caseinate works as an emulsifier because casein molecules have both hydrophilic and hydrophobic groups that can attract to water and fatty substances to achieve emulsification.
