“…The overall migration of PLA/ZnO nanocomposite films in food simulations includes PLA matrix, ATBC, and nano‐ZnO. Overall migration is affected by polymer type and the food simulant 26 . The overall migration value of PLA, PLA‐1, PLA‐3, PLA‐5, PLA‐7, PLA‐9, and PLA‐15 to 10% ( v /v) ethanol and isooctane is shown in Figure 2.…”

In this study, polylactic acid (PLA) films with different nano-ZnO concentration (0, 1, 3, 5, 7, 9, and 15%wt) were obtained by casting method. Overall migration values and specific migration values were studied in different food simulants (10% [v/v] ethanol and isooctane). The results demonstrated that overall migration of the composite films and specific migration of Zn 2+ was higher in 10% (v/v) ethanol solution than in isooctane solution. The release of Zn 2+ was affected by the percentage of nano-ZnO in the composite films and food simulants. The migration of Zn in this study was mainly caused by polymer softening and degradation leading to the dissolution of Zn. Scanning electron microscope analysis indicated that with the migration of Zn 2+ , the structure of the composite films changed greatly. Differential scanning calorimeter analysis indicated that the thermal stability was decreased and the glass transition temperature and crystallization temperature were reduced.

“…Most of the materials used in food packaging industry are synthetic polymers obtained from petrochemical products, which cause serious environmental problems due to their non-degradability [7]. In the field of active packaging, biodegradable and natural biopolymers (such as polysaccharides and proteins) have attracted more and more attention [8,9].…”

In this study, lychee (Litchi chinensis Sonn.) pericarp powder was added to chitosan (CHS) matrix to develop active packaging films, and their structure, physicochemical, antibacterial, antioxidant, and functional properties were investigated. FT-IR results showed that intermolecular hydrogen bonds were formed between CHS and polyphenols in lychee pericarp powder (LPP), and the intermolecular interaction interfered with the assembly of CHS into semi-crystal structure, which reduced the crystallinity of CHS film. Incorporation of LPP significantly reduced water vapor permeability, water solubility, swelling degree, and elongation at break of CHS film (p < 0.05). However, UV-visible light barrier, tensile strength, and antibacterial and antioxidant properties of CHS films were increased by LPP incorporation. CHS-LPP film remarkably lowered the weight loss, firmness, titratable acidity, and total soluble solids of fresh-cut apple after five days storage. CHS-LPP film packaging effectively inhibited the browning of fresh-cut apple and the reduction of polyphenol content in apple juice caused by polyphenol oxidase (PPO)-mediated oxidation during storage. Therefore, CHS-LPP films have great potential as food packaging material to ensure the quality and extend the shelf life of food products.

“…Since 2006, the FDA has been working to identify sources of nanomaterials, estimating the environmental impact of nanomaterials and their risks on human, animal, and plant health (Jeevanandam et al, 2018). The FDA constituted a Nanotechnology Task Force in 2006, which is charged with developing supervisory approaches to nano-based products that will ensure safety and efficacy and also help in beneficial technological innovation (Zabihzadeh Khajavi et al, 2019). The FDA, the EU, and other international regulatory authorities provide detailed guidance and information to evaluate the safety of NPs applied in food packaging, and also on the development of standardized procedures to analyze the risk of NPs on human health and on the environment (Kumar et al, 2022).…”

Nanotechnology emerged as a revolutionary technology in various fields of applied sciences, such as biomedical engineering and food technology. The pivotal roles of nanocompounds have been explored in various fields, such as food protection, preservation, and enhancement of shelf life. In this sequence, metallic nanoparticles (MNPs) are proven to be useful in developing products with antimicrobial activity and subsequently improve the shelf life of agrifoods. The major application of MNPs has been observed in the packaging industry due to the combining ability of biopolymers with MNPs. In recent years, various metal nanoparticles have been explored to formulate various active food packaging materials. However, the method of production and the need for risk evaluation are still a topic of discussion among researchers around the world. In general, MNPs are synthesized by various chemical and physical means, which may pose variable health risks. To overcome such issues, the green synthesis of MNPs using microbial and plant extracts has been proposed by various researchers. In this review, we aimed at exploring the green synthesis of MNPs, their properties and characterization, various ways of utilizing MNPs to extend their shelf life, and, most importantly, the risk associated with these along with their quality and safety considerations.
