The application of nanotechnology in the food industry is caused by the need to ensure food security, increase the life expectancy and quality of life of the people. Nanotechnology is used in food processing (nano additives, anticaking agent, gelating agent, nanocarriers) and food packaging (smart packaging, active packaging, improved packaging) [1]. 
Nanotechnology in food processing can improve the quality and taste of food. Nano encapsulation techniques are used to preserve smell. Through, encapsulating cyanidin-3-O-glucoside (C3G) molecules within the inner cavity of apo recombinant soybean seed H-2 subunit ferritin (rH-2) improved the thermal stability and photostability [2]. Nanoemulsions may be used to enhance water-dispersion and bioavailability. TiO2 and SiO2 nanoparticles may be used as food additives.
Food packaging based on nanotechnology has a number of advantages, namely, increased mechanical strength and antibacterial properties. Because some nanoparticles, such as silver, copper, chitosan and metal oxide nanoparticles, have antibacterial properties. And the applications of ZnO-NPs packaging in food systems concentrate on its antibacterial effect, and they are used to prolong the fresh food products’ shelf-life [3].
Thus, the use of nanotechnology in the food industry can improve the nutritional characteristics of food, increase strength and other technical characteristics of food packaging.
