Descripción

Microbial decay limits the storage, quality and trade of mangoes (Mangifera indica). We developed an active chitosan coating containing zinc oxide nanoparticles (ZnO-NPs) and Eucalyptus radiata essential oil (EEO) to inhibit decay and preserve postharvest quality of mango. Chitosan (cationic) can disrupt microbial membranes; ZnO-NPs act mainly via reactive-oxygen-species generation and Zn2+ interactions; EEO (rich in oxygenated monoterpenes) perturbs lipid bilayers, offering complementary antimicrobial actions.
