Abstract

Natural polymers are non-toxic, affordable, and abundantly accessible; hence they're often used in edible coatings. Covering vegetables with edible coatings that include antimicrobials, browning inhibitors, and nutraceuticals is a unique way to increase their nutritional value. Natural polymers are non-toxic, affordable, and abundantly accessible; hence they're often used in edible coatings. Covering vegetables with edible coatings that include antimicrobials, browning inhibitors, and nutraceuticals is a unique way to increase their nutritional value. Most edible coatings employ non-toxic, inexpensive, readily accessible natural polymers. Using biodegradable synthetic polymers and liquid and solid lipids, nano systems may be built at room temperature. To minimise food waste, edible food packaging utilises high-quality, low-impact packaging materials. Dairy consumer goods are among the industries targeted by the attack. Polymer nanocomposites, a kind of nano reinforcement, may act as a small gas barrier by increasing the difficulty of passing through the material. To put it simply, we now have the ability to accurately estimate the shelf life of our products thanks to developments in packaging technology, as well as biodegradable packaging and several other advantages. Packaging nanotechnology applications are categorised by their principal function. In conclusion, biodegradable synthetic polymers and liquid and solid lipids may also be used to create nano systems at ambient temperature. It is argued that recent advances in the usage of nano systems such nanoparticles, nanotubes, composites, and emulsions, are reviewed critically in this study. For food preservation purposes, nano dispersions may be supported by polymers, although the main focus of this article was on providing information on nano systems and how they can be used in various food substrates.
