Abstract: Chitosan is the second-most abundant natural biopolymer that possess excellent nontoxic, antimicrobial, biocompatible and biodegradable properties and has been used as a protective finish in food industry because of its proven antimicrobial activity. Various nanocomposites of chitosan exhibited better antimicrobial performance than Native chitosan biopolymer. This article seeks to review extensively the use of nano fillers like metal ions metal oxides, referred to as chitosan nanoparticles, for significant improvement or better use of antimicrobial properties of chitosan in food industry with the help of nanotechnology to increase the shelf life of fruits and vegetables. The article also studies in detail the extended properties of the target, methods of application, its effect and the microorganisms inhibited in the process
