To enhance the stability and sterilizability of chitosan-based coatings and expand the application of specific nanoparticles into food preservation, Ag/TiO₂ composites are synthesized to functionalize chitosan coatings for egg preservation. The eggshell morphology, weight loss, Haugh unit and albumen pH are used to characterize the preservation performance of the coatings.
