Magnesium oxide nanoparticles: A review of antimicrobial activity and food safety

Bacterial contamination reduces the shelf-life of foods and presents serious risks to human health. Nanotechnology has important applications in food safety and quality control. Nano-inorganic metal oxides have shown the potential to reduce bacterial contamination of foods. Magnesium oxide (MgO) is an inorganic compound widely used in everyday applications. MgO is currently intruduced as a generally recognized as safe material by the Food and Drug Administration and is used as food additives. Many studies have shown that MgO NPs have good antibacterial activity. Therefore, this review focuses on antibacterial activity and antibacterial mechanisms of MgO NP and its application in food safety.
