Nanotechnology has emerged as a technological advancement that can improve and change the food technology, with the potential to increase productivity and food security. Nanotechnology applications in food industry include: encapsulation and delivery of substances in targeted sites, increasing the flavor, introducing antibacterial nanoparticles into food, prolonging shelf life, sensing contamination, improved food storage, tracking, tracing and brand protection. Nano food processing and products can change the color, flavor, or sensory characteristics; they also change the nutritional functionality, remove chemicals or pathogens from food. Nano food packaging materials may extend food life due to high barrier packaging, improve food safety, alert consumers that food is contaminated or spoiled, repair tears in packaging, and even release preservatives to extend the life of the food in the package. Nanoencapsulation improves stability of certain food compounds. Nutraceutical compounds provide health benefits for consumers . also, nanocomposites improve barrier properties for the food .the technology is growing and requires more research.
