ABSTRACT: The work carried out here opens another perspective in the valorization
of sweet potatoes produced in Congo
Brazzaville other than those proposed by BOULA and all. We have shown in
this work that the hydrophilic property of starch which limits the production
of starch-based bioplastics can be inhibited by using the effects of photonic
incandescence. Indeed, light significantly impacts the bioplastic matrix
causing a decrease of the sites likely to bind water molecules. However, it
would be desirable to apply rheology for a better follow-up of this
cross-linking phenomenon. The synthesized retrograde bioplastic having
undergone a photonic stress shows better physical properties to be used as
packaging and thus to answer the environmental protection.
