The preparation and characterization of bioactive fibers made from pulps of cherry and Surinam cherry, and a polymeric matrix of Eudragit® L100 using electrospinning technique was investigated. The chemical characterization of the pulps obtained from cherry and Surinam cherry revealed that they are good sources of vitamin C (721.34 mg/100 g and 25.23 mg/100 g), carotenoids (3,138.5 µg/100 g and 14,015.5 µg/100 g) and phenolic compounds (784.89 GAE/100 g and 285.84 GAE/100 g. Their encapsulation in ultrafine fibers of Eudragit® L100 by electrospinning was successfully achieved. The morphology of the fibers was observed using scanning electron microscopy (SEM). The fibers obtained had dimensions in the microscale range. The images showed that the best preparation conditions to generate uniform and homogenous fibers involved Eudragit® L100 at a concentration of 15% together with the addition of 3% pulp while applying 15 kV and 20 kV voltages.
