N2 - In this work, the study of the effect of the incorporation of aqueous extract of mango skin (EPM) on the properties of biodegradable films made from potato starch is presented and its potential to be used as active packaging is presented. The EPM was added in the gelatinization process in concentrations of 5, 10 and 15% wt. The properties of the manufactured films were characterized using Scanning Electron Microscopy (SEM), FTIR Spectroscopy, water absorption kinetics and Stress-Strain curves. SEM micrographs show a formation with a smoother surface, without voids or cracks in EPM films. The FTIR analyzes confirm the formation of starch bioplastic by the presence of the functional groups O-H, C-H, C-O and O = H. On the other hand, it is confirmed that by adding EPM an increase in the stiffness of the films is achieved, but a decrease in elasticity, however, the ability to absorb water is not affected. This work highlights the benefits of the use of agricultural residues and its potential for the manufacture of materials that could be used in the food industry as active packaging.
