Abstract
The present disclosure describes methods for reducing the content of minerals, metals, ions, and/or other undesirable contaminants in vegetable oil, such as corn oil, obtained from fermentation of ground vegetable material. In one aspect, the methods herein produce distiller's corn oil having low amounts of minerals, metals, ions, and/or other contaminants rendering the corn oil more suitable for various further uses, such as biofuel production, with little to no additional refining.

A method of recovering vegetable oil from fermentation of ground vegetable material where the recovered vegetable oil has a reduction in minerals, metals, ions and/or other contaminates, the method comprising:
- fermenting a sugar obtained from ground vegetable material to produce a fermentation product including ethanol and a byproduct thereof that includes one or more of water, residual ground vegetable material, and vegetable oil;
- separating a process stream from the byproduct and wherein the process stream includes a portion of the vegetable oil;
- and
- adding a demulsifier to the process stream and recovering the vegetable oil from the process stream or recovering the vegetable oil from another stream obtained from the process stream.
