Abstract:
The invention provides methods and compositions for recovering oil from stillage. The method comprises the addition of a surfactant and a microparticle comprising hydrophilic silica to a grain to ethanol stillage. The methods and compositions of the present invention release oil trapped in solid aggregates, increasing the total amount of oil extracted from the stillage.
