Sustainable Bio-Based Chitosan/Shellac–Spinel Nanocomposite Coatings for Postharvest Preservation of Tomatoes and Cucumbers
Sustainable coatings based on biodegradable biopolymers can reduce postharvest losses and extend the shelf life of fresh produce. This study evaluated chitosan/shellac coatings reinforced with CoAl2O4 or CuAl2O4 spinel nanoparticles as laboratory-scale postharvest coatings for tomatoes and cucumbers. The coating system...
