 Nanotechnology has been used extensively in the food industry to improve the quality and safety of food products. It can be used to modify the physical properties of food particles such as particle size, shape, and surface charge, as well as to deliver nutritional supplements and sensory enhancers. Additionally, nanoparticles can be used to protect food from contaminants and extend its shelf life. Furthermore, nanotechnology can be used to develop smart food packaging that monitors the quality of stored foods.
