AB Conventional plastics can be substituted for protein-based bioplastics due to their natural origin and their biodegradability.Nevertheless, their properties are inferior to those obtained for synthetic plastics. The chemical crosslinking of these bioplasticswith aldehydes could improve their properties to compete in the actual market. Thus, the main goal of this articlewas to assess the influence of the incorporation of aldehydes with different aliphatic chain length on the physicochemical(crosslinking degree, colour and transparency), mechanical (flexural and tensile behaviour) and functional (water uptakecapacity and biodegradability) properties of protein-based bioplastics. In this sense, pea protein, a by-product of foodindustry, was used as raw material, processing it by injection moulding to obtain the bioplastics. Formaldehyde, glyoxal andglutaraldehyde were the aldehydes used as crosslinking agents. The results show the rise of the mechanical properties withthe incorporation of the aldehydes, depending on the degree of crosslinking they generate. All this also causes a consequentloss of the water uptake capacity and an increase in biodegradability time. In conclusion, this work opens a new alternativeto develop sustainable bioplastics that can be used in the market.
