The demand for plant proteins has increased significantly due to consumer's concern for sustainability and various health benefits, although their wider utilisation is still limited. This review provides an update of recent literatures to produce and characterise plant-protein-derived peptides, for applications in food emulsions. The hydrolysis duration, pH value, temperature, type of enzyme and degree of hydrolysis (DH) affect functional properties such as emulsifying capabilities and antioxidant activities of plant peptides. Moderate pH and a well-controlled DH lead to improved emulsification capability of the peptides. A comparison of emulsifying-activity index, emulsion-stability index and antioxidant capacity of peptides from different plant sources is presented as well. All rights reserved, Elsevier.
