Edible coatings have been demonstrated to preserve highly perishable fruits to reduce food loss, address chronic undernourishment, minimize health concerns, and improve environmental sustainability. However, existing biobased edible coatings face limitations in functionality and oxygen permeation control, hindering their effectiveness in preserving fruits. In this study, we have developed a multi-functional biobased conformal coating using a dipping process incorporating nanocellulose, bee wax, and curcumin. This innovative coating effectively extends the shelf life of fresh fruits by restraining cellular metabolism, minimizing water loss, and preventing microbial contamination. To tailor oxygen permeation, we have proposed a universal coating thickness power law with high accuracy, along with fruit oxygen barrier lines/bands, ensuring the best preservation performance. Our coating is transparent, washable, and biodegradable while also possessing excellent mechanical strength, antibacterial properties, and antioxidant capabilities.
