Abstract
Compositions for increasing corn oil recovery and embodiments of methods for using the composition for corn oil separation are described. The composition(s) incorporate an admixture that includes a polymer selected from a polyglycol ester, a polyethyleneoxide-polypropyleneoxide block copolymer, a poloxamine, or a mixture thereof. The methods include admixing the compositions with a process stream for, for example, the extraction of oil from milled corn and residues from a fermentation step, including stillage (e.g., thin stillage or mid stillage), distiller's wet grain, distiller's dry grain and distiller's dry grains with solubles.
