Special Issue Information

Dear Colleagues,

This Special Issue focuses on the modification and functional enhancement of egg-derived proteins. Egg proteins are widely used in the food and food-related industries due to their excellent nutritional value and functional properties. However, to meet the diverse demands of modern applications, various modification techniques have been developed.

We welcome original research and review articles that explore the following aspects:

  • Novel modification methods for egg proteins, including physical, chemical, and enzymatic modifications.
  • Investigation of the relationship between modification and enhanced functional properties, such as solubility, emulsifying ability, foaming properties, and gelation.
  • The applications of modified egg proteins in food products, such as bakery, dairy, meat products, and functional foods.
  • Enhancement of egg protein functions through the addition of active substances such as flavonoids and polyphenols.
  • Understanding the mechanisms underlying the modification and functional enhancement at the molecular level.

This Special Issue aims to provide a platform for researchers and industry professionals to share their latest findings and promote the development and application of modified egg-derived proteins in the food field.

Meringue has limited the use of meringue for personalization because of its thermally unstable system. Citric acid (CA) enhancement of egg white protein (EWP) foaming properties is proposed for the preparation of 3D-printed meringues. The results showed that CA increased the viscosity, exposure of hydrophobic groups (79.8% increase), and free sulfhydryl content (from 5 µmol/g to 34.8 µmol/g) of the EWP, thereby increasing the foaminess (from 50% to 178.2%). CA treatment increased the rates of adsorption, stretching, and orientation of EWP at the air–water interface to form multiple layers, resulting in a delay in foam thinning. The secondary structure of CA-treated EWP remained intact, and the exposure of amino acid residues in the tertiary structure increased with the expansion of the hydrophobic region. CA-treated EWP-prepared protein creams had a suitable viscosity (from 233.4 Pa·s to 1007 Pa·s at 0.1 s−1), shear thinning, structural restorability, and elasticity, which ensured good fidelity of their printed samples. Experiments involving 3D printing of CA-treated EWP showed that CA could significantly enhance the 3D printing fidelity of EWP. Our study could provide new ideas for the development of customizable 3D-printed foam food products. Full article
