The aim of this study was to elucidate the mechanism by which protein molecules become denatured in foam. It was found that damage to the protein is mainly due to surface denaturation at the gas-liquid interface. A fraction of the molecules adsorbed do not refold to their native state when they desorb. The degree of denaturation was found to correlate directly with the interfacial exposure, which, for mobile or partially mobile interfaces, is increased by drainage. Experiments with two differ...Expand abstract
