Electrospinning of Nanofibers Incorporated with Essential Oils: Applications in Food

Nowadays, modern food preservation techniques have emerged in the last decade. Recently, a combination of nanotechnology and active packaging has allowed the incorporation of bioactive compounds, such as essential oils, into nanoscale electrospun fibers. This phenomenon provides a new horizon in food safety and preservation. The incorporation of essential oils into electrospun nanofibers can extend the duration of antimicrobial and antioxidant activity of essential oils, which subsequently leads to longer shelf life, better preservation, and superior quality of food. In the current paper, the essential oils incorporated into nanofibers have been reviewed. The fabrication of nanofibers is usually carried out using different substances by applying various manufacturing methods, including needleless and needle-based electrospinning techniques. In this study, an emphasis on the antioxidant and antibacterial effects of electrospun nanofibers loaded with essential oils and their application in food models has been laid. Nevertheless, other challenges associated with using nanofibers incorporated with essential oils, such as their impact on organoleptic properties, cytotoxicity, and durability, have been discussed to achieve a holistic view of applying the electrospinning techniques in the food industry.
