The food sustainability and safety issues are one of the biggest challenges that are faced by the developing countries as a result of the growing human population. Applications of nanotechnology enable a straightforward, alternative, and dependable technology for such issues. Various metal nanoparticles (NPs) have been shown in multiples research over the years to exhibit antibacterial and barrier capabilities, hence revolutionizing the packaging of various processed and fresh commodities. Additionally, improved outlook of metal nanomaterials has risen the availability of nanotechnology-based food items. Such an advancement in nanotechnology may provide a variety of solutions for issues associated with foods, their storage, shelf-life and may offer sustained economic, commercial and health benefits. Silver nano-particles (Ag NPs) in particular has a significant impact on sustainability and active & intelligent packaging due to their tunable physico-chemical, biological and enhanced biocidal properties. However, the challenges in assessing the safety of nanofoods and nano-packaging should be addressed in such a way so that socio-environmental interests are not compromised. Thus, this article presents a review, to provide scope of Ag NPs in food technology along with the recent advancements in food packaging industry.
