Abstract
In this era, where food safety and sustainability are paramount concerns, the utilization of zinc oxide (ZnO) nanoparticles (NPs) is a promising solution to enhance the safety, quality, and sustainability of food products. ZnO NPs in the food industry have evolved significantly over time, reflecting advancements in synthesizing methods, antimicrobial activities, and risk assessment considerations for human health and the environment. This comprehensive review delves into the historical trajectory, current applications, and prospects of ZnO NPs in food-related contexts. Synthesizing methods, ranging from solvothermal and solgel techniques to laser ablation and microfluidic reactors, have facilitated the production of ZnO NPs with tailored properties suited for diverse food applications. The remarkable antimicrobial activity of ZnO NPs against a wide spectrum of pathogens has garnered attention for their potential to enhance food safety and extend shelf-life. Furthermore, comprehensive risk assessment methodologies have been employed to evaluate the potential impacts of ZnO NPs on human health and the environment, regarding toxicity, migration, and ecological implications. By navigating the intricate interplay between synthesis methods, antimicrobial efficacy, inhibitory mechanisms, and risk assessment protocols, by elucidating the multifaceted role of ZnO NPs in shaping the past, present, and future of the food industry, this review offers valuable insights and promising avenues for researchers, policymakers, and industry stakeholders to enhance food safety, quality, and sustainability.
