Technical Abstract: The fabrication of active packaging materials based on natural polymers is increasing in recent years. Electrohydrodynamic processing has drawn attention in food packaging due to its potential in fabricating materials with advanced structural and functional properties. These materials have the significant capability in enhancing the food's quality, safety, and shelf life. Through electrospinning and electrospraying, fibers and particles are encapsulated with bioactive compounds for active packaging applications. Understanding the principle behind electrohydrodynamics provides fundamentals in modulating the material's physicochemical properties based on the operating parameters. This review aims to provide a deep understanding of electrospraying and electrospinning, along with their advantages, from food packaging perspectives. The natural polymers suitable for developing active packaging films and coatings through electrohydrodynamics is intensely focused. The critical properties of the packaging system are discussed with characterization techniques. Furthermore, the limitations and prospects for natural polymers and electrohydrodynamic processing in active packaging are summarized.
