Abstract Petroleum-based polymers are still widely used for food packaging applications. Thereby, the continuous use of these nondegradable materials especially in the food industry cause a severe global risk to human health and environment. To this end, researchers have been focusing on the development of ecofriendly packaging materials from natural resources. However, the films produced from natural biopolymers have inferior properties compared to the synthetic polymers. To tackle this issue, the packaging based on bionanocomposites has recently been emerged in the food packaging technologies. Moreover, after the COVID-19 pandemic appearing, the fabricating active and intelligent packaging materials has become the highest demand for catering to market needs in order to ensure the food safety and food quality. By 2030, perhaps active and intelligent packaging will completely replace traditional packaging itself. Therefore, the aim of this work was to prepare and develop ecofriendly materials based on bio-polymeric nanocomposites for sustainable food packaging applications. In the present study, bioplastic films were developed from biomaterials with two types of nanofiller namely (i) novel biosynthesized metal oxide nanoparticles (MgO NPs) using Boswellia serrata gum (BSG) (ii) Functionalization of synthesized GO by natural antimicrobial gum rosin (RO) and dapsone (DAP) to be used in active and/or intelligent food packaging applications. Specifically, the first part of this study was focused on biosynthesis of MgO NPs for improving the properties of the PVA/Gelatin nanocomposites for smart food packaging applications. |
