Processing conditions used to elaborate maize derived bioplastics later exposed to CO₂ supercritical foaming conditions.

Plasticizers: Peg400: polyethylene-glycol 400; uf: urea/formamide; sg: sorbitol and glycerol mixture (1.4:1 wt/wt). Bioplastics: TPZ: thermoplasticized zein; TPS: thermoplasticized starch; TPBMx: thermoplasticized blue maize (x is a suffix that indicate extrusion temperature); TPmBM: thermoplasticized chemically modified blue maize (as described in materials and methods); Mix[TPSy+TPZ]a: thermoplasticized Blends of TPS and TPZ (80:20 wt/wt). The y subindex indicates the plasticizer used to produce TPS. aBlends were produced using the close mode compounding described in materials and methods.
