Assessment of interfacial and foaming properties of bovine sodium caseinate glycated with galactose

► SC glycoconjugates have a high elastic character and cohesion of the interfacial film. ► SC glycoconjugates show interfacial features suitable to stabilize the foam at pH 5. ► Glycation of SC with galactose is an efficient method to improve foaming properties. ► Glycation of SC may extend its applicability range as a foaming agent in acidic foods.
