Mandarin oranges are susceptible to senescence and decay, primarily due to postharvest quality loss and fungal infections. This study aim to develop edible and active coatings using carnauba and shellac incorporated with carvacrol nanoemulsion (CNE), and to examine the synergistic effects of the coating on the quality parameters and shelf-life of the mandarin oranges during ambient storage. Nanoemulsion of carvacrol with average droplet size of 348.8 nm was prepared, showing a polydispersity index value of 0.211, showed excellent antifungal activities. Five coating formulations were developed and applied on the mandarin oranges. The coating containing 2 %,
