Abstract
The invention is a corn product removal process that successfully extracts oil and zein from dry-milled corn. Oils and zein are extracted from corn using ethanol. Corn solids are separated from the ethanol, oil and zein mixture produced in the step of extracting. Thereafter, the ethanol, oil and zein mixture are membrane filtered to restrain zein from the mixture and pass an oil and ethanol mixture. At least one of zein or oil is then selected to be separated for an output corn product.
