Nanotechnology is a newly emerging novel food packaging technique, which can increase the shelf life of foods, minimize the spoilage, ensure the food safety, repair the tears in packaging, reduce the problem of food shortage, and finally improve the health of the people. Food packages embedded with nanoparticles can alert the consumer about the safety of product. It can release preservatives to extend shelf life of food in package. Currently, food packaging and monitoring are a major focus of food industry related nanotechnology research.
