ABSTRACT
Electrospinning is a physical process that enables the straightforward production of nanofibers by subjecting polymer solutions to high electric fields. The polymeric nanofibers obtained are considered as outstanding nanomaterials for a broad range of technological purposes. In this regard, electrospun nanofibers have been used with success to develop packaging materials with improved performance properties, resulting in promising edible films and coatings. Materials based on electrospun nanofibers have exhibited potential applications as novel active packaging materials, especially by their feature as carrier of active agents in an encapsulation system. This chapter presents the electrospinning process for the elaboration of nanofibrous materials, the different types of polymers considered as electrospinnable materials intended for food packaging applications, and their uses as encapsulating materials for the delivery of active ingredients. Moreover, performance characterization techniques, methods for antimicrobial studies, as well as potential application of electrospun nanofibers in food preservation are also approached. Finally, future trends regarding the use of this novel and emerging technology are analyzed, and main concluding remarks are presented.
