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.
