Nanotechnology has been used to treat illnesses for a long time. It has been successfully employed as a means of drug discovery. However, it's used in food preservation is yet to become commonplace. Through this review paper, the authors wish to throw light on the application of nanoparticles in the preservation of food, to improve food color, texture as well as flavor. We also explore the use of nanotechnology in the encapsulation of the foodstuffs as a means of preservation. The article includes details about the usage of nanoparticles in the nutraceutical industry as well as its usefulness as a nanosensor. The purpose of the paper is to make use of nanotechnology in the food industry a well-known application of nanoparticles. It will be useful for professionals working in the food industry or entrepreneurs who wish to venture into the field of food preservation. Scientists may use the information and data provided in the paper to further their research.
