? 2022 Elsevier B.V.Oregano essential oil (OEO) has great antioxidant and antifungal potential as a natural bioinhibitor, which is limited by its volatility and instability. In this study, OEO was loaded onto mesoporous nanosilica (MNS) to prolong the efficacy of biological inhibitors and then oxidized esterified tapioca starch (OETS) was used as a film-forming matrix to develop bio-nanocomposites for packaging by the casting method. Transmission electron microscopy (TEM), fourier transform infrared (FT-IR), and thermogravimetric analysis (TGA) were used to analyze the loading effect of nanoparticles. Then, the microstructure, physical, barrier, antioxidant and antifungal properties of the active films containing OEO–MNS were evaluated and compared with those of the OETS-based film. The results showed that the presence of OEO–MNS endowed the film with antioxidant, antifungal, and ultraviolet-blocking properties, as well as improved tensile strength (TS) and water resistance. Specifically, the best performance was obtained for the OETS-based film containing 0.9% OEO–MNS with a uniform nanoparticle distribution. Meanwhile, the TS of the active films reached up to 6.97 MPa, which was about 236% higher than that of the pure OETS-based films. In addition, the film incorporating 1.5% OEO–MNS had the highest antioxidant capacity and excellent antifungal activity. The prepared multifunctional nanocomposite films containing essential oil have promising applications in the field of active packaging.
