Packaging of food products is one of the most important stages of the food supply chain. Nano-size materials for packing food substances with appropriate properties result in better packaging performance and longer food shelf-life. In this review, the application of ZnO nano-size in active packaging of foods is discussed to identify gaps in applications for food packaging and safety. First, the crystal structures and morphologies of modified ZnO nanoparticles (ZnO NPs) are presented, and their s
A series of PLA/ZnO bionanocomposite films were prepared by introducing positively surface charged zinc oxide nanoparticles (ZnO NPs) into biodegradable poly(lactic acid) (PLA) by the solvent casting method, and their physical properties and antibacterial activities were evaluated. The physical properties and antibacterial efficiencies of the bionanocomposite films were strongly dependent on the ZnO NPs content. The bionanocomposite films with over 3% ZnO NPs exhibited a rough surface, poor disp
Abstract Relatively high aspect ratio exfoliated graphite ( EFG ) particles with an average size of 7.4 µm and a nanometer sized thickness of 30–50 nm were successfully prepared by thermal treatment at 1050 °C and subsequent ultrasonication for application as a filler to improve the physical properties of eco‐friendly poly(propylene carbonate) ( PPC ). A series of poly(propylene carbonate)/exfoliated graphite ( PPC / EFG ) nanocomposite films with different EFG contents were prepared via a solut
Ethylene biosynthesis from fresh produce could accelerate the ripening and reduce the postharvest life under conducive conditions. Ethylene scavenging systems, an active packaging, serve to prolong the shelf life of fresh produce and prevent deterioration caused by ethylene. This review provides an overview of ethylene scavenging mechanisms such as chemical oxidizing, ethylene receptor blocking, ethylene adsorption, and ethylene photocatalytic oxidizing. Particularly, the scope of this study is
The global environmental issues caused by plastic incineration are continuously increasing, along with the demand for polyethylene terephthalate (PET)—27 million metric tons of PET was demanded in 2020. Therefore, PET recycling has emerged as the core of the global circular economy. In particular, PET recycling methods are categorized into two pathways: mechanical and chemical recycling, wherein mechanical recycling is more efficient than chemical recycling. However, PET undergoes heat-induced d
