Proteins constitute one of the most important groups of emulsifying agents used in foods; they stabilize the oil droplets against coalescence as well as reduce the oil–water interfacial tension and in this way contribute to the formation of oil droplets. The requirement for a protein to exhibit satisfactory emulsifying properties is the ability of the molecules to adsorb rapidly at the newly created oil–water interfaces during the process of emulsification and to undergo conformational change and rearrangement at the interface, followed by formation of a cohesive film with viscoelastic properties as a result of intermolecular interactions,
