Role of AuNPs in Active Food Packaging Improvement: A Review

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.

Automated summary

There is a growing concern among food science researchers about food loss due to reduced shelf life. Improved food packaging techniques, especially those based on nanotechnology, are highly welcomed in the food industry. Nanotechnology-based techniques, such as metal-based nanoparticles, have shown potential in addressing the challenges of shortened shelf life and environmental concerns. Green synthesis-based methods for gold nanoparticles have gained great interest due to their advantages over conventional chemistry-based methods. These methods simplify the administration of gold nanoparticles and offer increased stability and anti-microbial or antioxidant properties. However, the potential hazards, including migration, of gold nanoparticles in food packaging need to be considered.
