 PhD in Biotechnology, Universidade Católica Portuguesa (FP6 Marie Curie Actions)  Master Degree in Chemical Engineering, Universitá degli Studi di Salerno, Italy

 Valorisation of agro-food waste through the recovery of high-added value compounds  Food Safety and Food Security  Food Processing Engineering  International research projects (17 countries)  Academy to industry knowledge transfer

 Recovery of the structural fibrous proteins collagen, elastin and keratin, and respective hydrolysates and small peptides from animal waste, and  application in biomaterials, pharmaceutics, cosmetics and food  Add commercial value to a waste material currently underutilized in fine chemistry  Contribute to the sustainability of the agro-food sector  Reduce impact of waste on the environment

• Respective protopeptide in the form of α-helix having specific amino acids

heptad motifs and responsible for a spontaneous self-assembly into tridimensional networks

• Functional biopolymers which allow conceiving formulations for the bio-based

industry (medicine, pharmaceutics, cosmetics and food)

• The hydrolysis through enzymes, chemicals or thermal treatment, gives rise to

biologically active peptides (2-30 amino acids residues) which can modulate numerous physiological pathways

…some examples of application…

Collagen from cortical BONES Elastin from LIGAMENTS Keratin from FEATHERS Morphology of the fibres (Electron Microscopy at INRA, QuaPA) and supramolecular structure

Higher amount but easier management, low impact and low to zero costs of disposal

Million Tons/year

Protein-containing waste Polysaccharide-containing waste Lower amount but difficult management, slower degradation and very high costs of disposal (25–70 EUR/ton) On average, 1/3 of food is currently wasted worldwide
