New packaging materials are an emerging field in the food industry. Poor thermal, mechanical, chemical, and physical properties of biopolymers, and also their inherent permeability to gases and vapor have increased this interest. Biopolymeric materials (matrix) require fillers, which can react/interact with available matrix in order to provide new formulations with improved properties. Many studies have shown the potential use of metal nanoparticles in biopolymeric packaging and edible coatings for improving their properties. The current review summarizes the characterization of bio-nanocomposite films and edible coatings incorporated with metal nanoparticles on the shelf life and quality of tropical fruits, berries, climacteric/non-climacteric fruits and vegetables. It also provides a brief description of some advantages of bio-nanocomposite films and edible coatings applied to fruits and vegetables such as decreasing the color changes, respiration rate, weight loss and extended shelf life, delaying ripening and being environmentally friendly. The results of recent reports provide a better understanding of the impact of metal nanoparticles incorporated in biopolymers on the shelf life and the quality of fruits and vegetables.
