Enhanced acidic stability of O/W emulsions by synergistic interactions between okara protein and carboxymethyl cellulose

The application of okara protein (OP) in emulsions is yet to be fully explored. The present work aims to investigate the effects of carboxymethyl cellulose (CMC) - OP complexes on the emulsion properties and emulsion stability. CMC (0–5 g/kg) was introduced to electrostatically interact with the OP (10 g/kg) at pH 4.0, and then O/W emulsions (1:9, g/g) were prepared by the complexes and systematically characterized. As the CMC concentration...
