• The gel particles of TUEP and UEP became smaller under ultrasonic treatment. • Ultrasonic treatment can improve the hardness and WHC of TUEP and UEP. • The improvement effect of TP assisted ultrasound is better than that of ultrasound. • Ultrasonic treatment is very effective method for modifying egg white protein gel.
Egg white protein (EWP) was one of the high‐quality protein sources and widely used in the food industries because of excellent emulsifying, gelling, and foaming properties. Polysaccharides as a natural biological macromolecule have been used to improve the functional properties of EWP. The electrostatic interaction was the main driving force between EWP and polysaccharides. However, protein‐polysaccharides complexes were susceptible to environmental factors including pH, ionic strength, polymer ratio, and temperature. In this paper, the functional properties of EWP were summarized. More importantly, the effects of polysaccharides on the functional properties of EWP were highlighted and reviewed referring to emulsifying, foaming, and gelling properties. The impact of environmental factors on the protein‐polysaccharides interaction were also discussed. This paper leaded to enrich research systems of protein‐polysaccharides interaction and provided information for the development of new egg white‐derived foods.
