Fundamental studies on water-washing of the corn ethanol coproduct (DDGS) and its characterization for biocomposite applications

► The enhancement in thermal stability of DDGS after water-washing was characterized. ► Unlike washing time, the effect of water-to-DDGS ratio was statistically significant. ► Washed DDGS retained the components important for its potential biocomposite usage. ► Tensile properties of washed DDGS biocomposite were superior to unwashed one.
