Abstract
Food nanotechnology is among the newest emerging technologies. This technology has very good treatments in the food industry in terms of food processing such as packaging, safety, and quality control. Nanotechnology plays an important role in the development of an ideal system for the proper encapsulation, safety, and delivery of nutraceuticals and functional foods. There are many advantages of using nanotechnology in the food industry. Some of these can be listed as an antimicrobial effect, increasing the heat resistance of food, increasing the shelf life of food, improved agricultural production, and perceiving food spoilage. On the other hand, nanomaterials and nanoparticles have risks in terms of toxicity and safety. By unconsciously consuming nanofoods, people also take in biopermanent nanoparticles, which can cause many ailments such as immune system disorders. In this review, the importance of nanotechnology in the field of nanofood, the widely used nanoemulsion technique in nanofood production and safety of nanofoods are discussed.
