Nano-food is the economic prospective of the food industry

For a decade, there has been tremendous interest in studying and advancing the food business using nanotechnology. Nano food aims to produce food items that are more nutritious, tasty, and cost-effective while also being safer. It has also reduced the amount of food that spoils. Using nanotechnology, an effective colloidal system for the correct encapsulation, safety, and distribution of nutraceuticals and functional meals has been developed in more significant portions. The use of nanotechnology in food is gaining popularity and offers the food business a vast array of opportunities. The improvement of plastic material barriers, the incorporation of active components that can deliver functional attributes beyond conventional active packaging, and the sensing and signalling of pertinent information are the three basic categories of nanotechnology applications and functionalities currently used in the development of food packaging. Nanotechnology-based food packaging materials have the potential to improve food safety, lengthen the shelf life of foods, patch tears in packaging, and even release preservatives to prolong the shelf life of the food inside the container. Nanotechnology applications in the food sector can provide more robust flavours and colours, increase barrier characteristics, and increase safety by detecting microorganisms in packaging.
