Nanotechnology has provided new opportunities for the food industry with its applications in food packaging. The addition of nanoparticles, such as clay, silver and copper, can improve the mechanical and antimicrobial properties of food packaging. However, nanoparticles may have an adverse impact on human health. This has led to legislative and regulatory concerns. The inhibitory effects of nano packaging on different microorganisms, such as Salmonella, , and molds, have been studied. Nanoparticles, like other materials, may have a diverse set of properties that need to be determined. In this review, different features of silver, clay and copper nanoparticles, such as their anti-microbial, cell toxicity, genetic toxicity, mechanical properties, and migration, are critically evaluated in the case of food packaging. Specifically, the viewpoints of WHO, FDA, and ESFA, concerning the nano-silver application in food packaging, are discussed as well.

Electronic address:
Multifunctional pH-responsive films were fabricated via layer-by-layer deposition of gelatin, chitosan, and carboxymethyl cellulose (CMC), incorporating selenium nanoparticles (SeNPs) and beetroot extract (BTE), to monitor and preserve beef freshness. SeNPs were synthesized and characterized via various techniques. BTE exhibited promising functional properties, and films demonstrated a significant color transition from red to yellow across pH 2-14.

This work pioneered an innovative visible light-powered, self-cascading peroxide antimicrobial packaging system (RPFe-CS), featuring a photodynamic enhancement effect achieved through the demand-oriented design of riboflavin sodium phosphate and Fe coordination complexes (RPFe) fillers with photodynamic and peroxidase activities, and the ingenious selection of slightly acidic chitosan (CS) film matrix. In this system, the photo-responsive properties of RPFe particles not only generate the •O, •OH, and O required for photodynamic sterilization, but also the produced HO serves as a necessary substrate for peroxidase to exert its bactericidal effect, endowing the packaging system with a "self-production and self-marketing" cascade process. The RPFe-CS film achieved efficient eradication to bacteria and fungi reaching up to 99.

The escalating environmental impact of non-biodegradable plastic waste has intensified global efforts to seek sustainable alternatives, with biodegradable polymers from renewable sources emerging as a promising solution. This manuscript provides the current perspectives, challenges, and opportunities within the field of sustainable and biodegradable packaging. Despite a significant market presence of conventional non-biodegradable petrochemical-based plastics, there is a growing trend towards the adoption of bio-based polymers from renewable resources driven by environmental sustainability and regulatory measures.
