Recent times have witnessed a growing demand for sustainable technology for food preservation that can retain its freshness, promises lower contents of additives and preservatives, safe consumption, eco-friendly milder processing technologies and eco-friendlier packaging solutions. Application of Biopolymers has served as the most sustainable and viable option to its synthetic counterparts. These biopolymers have been incorporated to develop biodegradable packaging like edible films and coatings owing to their biological origin. Nanoemulsion technology offers a leap forward to upgrade the features of conventional biodegradable packaging items. The present review discusses various trends and perspectives of nanoemulsion technology in post-harvest preservation for enhancing the shelf life of fresh fruits and vegetables. It investigates the interconnectedness between food preservation techniques, biodegradable packaging materials made from biopolymers, and nanoemulsions. It further addresses the preservation challenges post-harvest and underscores the limitations of conventional preservation methods, advocating for eco-friendly alternatives with a specific focus on the potential of nanoemulsions in enhancing food safety and quality. This review elaborates on the composition, formulation techniques, nanoemulsion products and role of nanoemulsions in the management of foodborne pathogens. Furthermore, it examines the potential health hazards linked to the use of nanoemulsions and stresses the significance of a regulatory framework for food safety. In conclusion, this review offers insights into the promising prospects of using nanoemulsions in food preservation.
