Corn byproducts have potential for use as bioplastics, as proteins can be functionalized. DDGS is a less expensive material compared to CGM, but is lower in protein, higher in fiber. Blends of DDGS/CGM were extrusion processed, then examined for moisture adsorption behavior. Equilibrium moisture contents ranged from 0% to 50%. Nonlinear modeling was used to determine effects of relative humidity and blend ratio.
