Methods and composition are provided for recovering oil from an oil containing mixture or emulsion. The invention is particularly applicable for recovery of oil from corn in a corn to oil process. The process and compositions comprise a combination of two non-ionic surfactants i) and ii). The non-ionic surfactant i) is a non-ionic surfactant comprising a polyol derived from a sorbitol, a sorbitan, or isosorbide. The non-ionic surfactant ii) is an ester of a) polyethylene glycol and b) a fatty acid. In accordance with the methods, the combination of surfactants i) and ii) is brought into contact with a process stream mixture existing in a corn to ethanol process.
A method for recovering oil in a corn to ethanol process wherein oil and solids are present in a process stream mixture, said method comprising adding to said process stream mixture an oil separation aid, said oil separation aid comprising i) a non-ionic surfactant comprising a polyol derived from a sorbitol, a sorbitan, or isosorbide and ii) a non-ionic surfactant selected from the group consisting of polyethylene glycol (PEG) dioleate, PEG dilaurate, PEG dipalmitate, PEG distearate, PEG monooleate, PEG monolaurate, PEG monopalmitate, and PEG monostearate.
Corn oil separation enhancement composition comprising components i) and ii) wherein i) is an alkoxylated sorbitan alkylate and ii) is a non-ionic surfactant selected from the group consisting of polyethyleneglycol (PEG) dioleate, PEG dilaurate, PEG dipalmitate, PEG distearate, PEG monooleate, PEG monolaurate, PEG monopalmitate, and PEG monostearate.
