... plant proteins have higher under cultivation grounds while the cost of production is lower than microbial origins. Thus, plant proteins are preferred to be used in food formulations. The problem concerning plant proteins is their grassy and bean-like odor and flavor. Further, these proteins have weaker functional properties (emulsifying, emulsion stability, foamability, and foam stability) in comparison with animal proteins. Thereby, it is suggested to be modified with physical, chemical, and enzymatic methods.
