Manufaktura metodoen eta saretze-erreakzioaren eragina gelatinazko materialen propietateetan

Abstract

Concerns about the usage and disposal of plastics have promoted the development of alternative materials to address a more sustainable use of resources. In recent years, in the specific field of proteins' research, the interest in gelatin-based materials has increased. With the aim of promoting proteins' market viability, gelatin films, scaffolds and biocomposites were prepared by solvent casting, freeze-drying and extrusion-injection techniques, respectively.  Furthermore, in order to reduce the water sensitivity of gelatin, materials were crosslinked with lactose, promoting the Maillard reaction by means of a heating process (105 °C, 24 h). Fourier transform infrared (FTIR) spectroscopy was used to confirm the interactions between gelatin and lactose. The values of water uptake capacity and the structures observed by SEM showed the effect of the crosslinking reaction and manufacture process on the gelatin-based materials' properties.
