Nanostructures like silver nanoparticles and nanoclay are being used in food packaging to keep food fresh for longer and protect it from harmful microorganisms. These tiny materials help extend the shelf life of food products without changing their taste or quality. Silver nanoparticles, in particular, have antimicrobial and antioxidant properties that make them effective in preserving food. By incorporating these nanostructures into packaging materials, food can stay safe to eat and ready-to-eat for a longer period. This technology is a promising way to improve food quality and safety while reducing food waste.
