摘要: The foaming and emulsifying properties of lupin seed protein isolate (LSPI) were investigated following structure modification by heating and/or dithiothreitol (DTT) addition. Heat-treatment solution resulted in an increase both foamability foam-stabilization ability while disulfide bond reduction DTT brought about improvement the capacity only. Additionally, heat-treated LSPI solutions exhibited markedly improved emulsification emulsion-stabilization properties. Disulfide reduction, on other hand, to stabilize emulsions against creaming influence its solubility surface-adsorption has also been studied order elucidate structure/functionality relationship protein.
