Sustainable development of crosslinked protein and peptide-based films from rapeseed meal to innovative elastic materials

vailability of proteins from agricultural by-products and their filmproperties fostered the interest in natural biopolymers as a renewablealternative to petrol-based plastics for the preparation of bioplastic. A sustainable approach is proposed herein to the develop cross-linked peptide-based films from rapeseed meal protein. We set up anovel highly efficient extraction method yielding a protein-enrichedextract. The process is reproducible, scalable, and eco-friendly, with agreat potential for industrial applications. Utilizing this protein/peptide mixture, films were obtained through pression molding
