The electrospinning technique produced zein fibers under the conditions and parameters established by Antunes et al. [36]. Firstly, the collector was covered with aluminum foil for the monolayer film; after, the collector was covered with chitosan-based film for the multilayer system. The distance between the collector and the needle was fixed for all samples at 10 cm. The process was carried out at a temperature of 23 ± 2 °C, controlled by an air conditioner and a dehumidifier with a relative humidity of 45 ± 2%.
