abstract = {Replacing conventional plastics with other products obtained from biobased and biodegradable raw materials is an increasingly studied solution. In this line, the development of protein-based bioplastics is a promising alternative. However, for
some applications, such as packaging it would be necessary to improve their properties by including an additional stage to
crosslink the protein chains during the production of bioplastics. Therefore, pea protein-based bioplastics crosslinked with
genipin, a natural non-toxic chemical crosslinking agent, are evaluated in this study. The bioplastics are obtained via injection moulding and genipin, is included in the initial formulation. Specifcally, the concentration of genipin and the efects
on the protein blends with genipin over days are evaluated. The evolution of the reaction is followed by the colour change
of the blend, together with thermal analyses and infrared spectroscopy. Results showed the evolution of the crosslinking in
the blends resulted in conformational changes that resulted in the modifcation of the initial yellowish colour to a blueish
system. Respect their bioplastics, more deformable systems with a lower water absorption capability are obtained by using
genipin as crosslinking agent},
