[EN] The present work studies the functional properties of active biodegradable starch films with encapsulation of Carvacrol (CA) by the Electrospinning (ES) technique. For this, starch films were obtained by melt mixing to obtain the pellet and compression molding using a hydraulic press to obtain the films. On these films, a solution of the biodegradable polymer Polycaprolactone (PCL) with and without Carvacrol was electro-deposited by means of ES and with different times of electro-deposition to obtain the different formulations with which to work in the subsequent tests. Thus, 5 formulations were obtained, two of them with only PCL and starch, at ES duration of 60 and 90 minutes, SP1S and SP2S respectively and two formulations incorporating Carvacrol for the same times, SP (CA1) S and SP (CA2) S, respectively. A control film was also obtained for the tests based on only starch (SS). Once the films were obtained incorporating of the active components, they were thermo-sealed in a hydraulic press in order to obtain the multilayer material. The fibers generated by ES were analyzed in terms of their kinetics of release of the active compound in different food simulants with different polarities. The fibers showed a higher rate of release in the less polar simulants, D1 (ethanol 50%) and D2 (Isooctane) (related to fatty foods) and, on the other hand, in these simulants an almost complete release of the CA was noted, due mainly to the affinity of monoterpene with these nonpolar substances. The starch films carrying electrospun fibers were studied in terms of their optical properties, oxygen barrier, water vapor barrier property, moisture content and mechanical properties. With the addition of the electro-deposited layer of PCL and CA, a reduction of water vapor permeability values against the starch-only film was observed, due to the hydrophobic nature of these two compounds in the films. Regarding oxygen permeability, the presence of PCL did not significantly modify this property that was already exhibited by the thermoplastic starch. With regard to the optical properties, the multilayers have brightness values less than 40 which can be considered matt, have an average lightness (L) and a slightly yellow hue (h). Regarding the mechanical properties, the presence of the PCL layer generated a decrease in the rigidity and breaking strength of the multilayers. The extensibility was affected with the presence of the layers containing the CA, observing less elasticity, perhaps due to the migration of the active, with weakening effect, in the starch layer.
