Role of AuNPs in Active Food Packaging Improvement: A Review

Abstract

There is a worldwide concern about food loss due to reduced shelf life among food science researchers. Hence, it seems that any techniques contributing to improved food packaging are most welcome in the food sector. It has been demonstrated that the administration of nanotechnology-based techniques such as metal-based nanoparticles can fade away the unresolved obstacles in shortened shelf life and environmental concerns. Along with substantial signs of progress in nanoscience, there is a great interest in the usage of green synthesis-based methods for gold nanoparticles as the most advantageous metals, when compared to conventional chemistry-based methods. Interestingly, those aforementioned methods have significant potential to simplify targeted administration of gold nanoparticles due to a large surface-volume ratio, and diminished biohazards, aimed at increasing stability, and induction of anti-microbial or antioxidant properties. However, it is necessary to consider the hazards of gold nanoparticles including migration for food packaging purposes.

Unveiling the Future: Nanotechnology's Role in Advanced Food Packaging

“…These novel packaging methods have not only improved the consumer experience but also fostered more efficient supply chains, catering to the growing demands of the contemporary food industry (Pushparaj et al 2022). In essence, the integration of nanotechnology within the food and beverage sector, coupled with advancements in packaging techniques, signifies a pivotal shift toward sustainable and consumer-centric practices, underlining the industry's commitment to ensuring the longevity and quality of food products in an ever-evolving market landscape (Ahari et al 2022).…”
