Original Paper


In this work, gelatin extracted from chromed leather waste (CLW) was used with cornstarch and glycerol to produce polymeric films. These films were compared with commercial gelatin ones. Gelatin from CLW presented a more pronounced plasticizer behavior than commercial gelatin. It may have occurred due to its lower molar mass, due to the presence of free amino acids from the partial degradation of the protein polypeptide chain during CLW gelatin extraction, and/or due to the presence of high salts content. The high drying temperature (40 °C) made the drying process faster than the starch retrogradation process. It resulted in the reduction of films crystallinity and tensile strength, and in the increase of elongation at break. It also increased equilibrium moisture content, as indicated by water sorption isotherms. FTIR spectra indicated that the absorption bands of cornstarch and CLW gelatin films are the same ones found for films of these materials when not combined, which indicates the presence of a system with phase separation.
