Abstract :
[en] tThe aim of this work was to evaluate physicochemical properties of chitosan-based films with differentfractions of arabinoxylans (AXs). Five fractions composed by AXs or mixtures of AXs and arabino-xylo-oligosaccharides (AXOS) obtained through three different processes were added to chitosan-based films.These films were obtained by solvent casting and characterized in terms of water vapor permeability(WVP), opacity, thickness, moisture content and mechanical properties (i.e., tensile strength – TS andelongation at break – EB), being the chemical interactions evaluated by FTIR.Moisture content values ranged between 20 and 30% for all five studied films being the lowest valueobserved for chitosan films with the fraction F1 of AX/AXOS (21.1%). The films with incorporation of F3a,F3b and F4 AXs fraction were more opaque (>10%) than the other studied films. Regarding mechanicalproperties CH films presented EB and TS values of 31.26% and 8.25 MPa, respectively, both these valuesremain statistically equal with the incorporation of AX/AXOS except for films containing the fractionF1 and F2. For films with the F2 fraction were obtained higher values of EB (41.31%) while for CH filmscontaining the F1 fraction the TS values (13.07 MPa) increased.In conclusion, wheat bran AXs can be successfully incorporated into chitosan-based edible films pro-viding, together with chitosan, an extra functional value to films, due their health benefits.
