ABSTRACT:
A corn product removal process for removing zein and/or oil from dry-milled corn. Oils and/or zein are extracted from corn using ethanol. Corn solids are separated from the ethanol, oil and zein mixture produced by extracting. Thereafter, the ethanol, oil and zein mixture is membrane filtered to restrain zein from the mixture and pass an oil and ethanol mixture. The zein and/or oil may be concentrated and purified.
