Aqueous extraction of corn oil after fermentation in the dry grind ethanol process. In: Farr, W., Proctor, A., editors. Green Oil Processing. Urbana, IL: AOCS Press. p. 53-70. Interpretive Summary: Technical Abstract: Corn oil is a popular vegetable oil in the US and in many other countries. Among all of the vegetable oils, corn oil ranks tenth in terms of annual worldwide production. Most commercial corn oil is obtained from corn germ that is a by-product of the wet milling industry. In recent years a new process was developed to produce corn oil in a dry grind ethanol plant, after fermentation using a combination of heating and centrifugation. It is estimated that this process is currently being used in at least 45 of the ~200 corn dry grind ethanol plants currently in operation in the US. Using this new process, about 576 million pounds of corn oil was produced in the US in 2010, which represents about 23%, relative to the 2400 million pounds of commercial corn oil (from germ) produced in the US in 2010. |
