摘要： Methods for producing oil from distillers corn oil having high free fatty acid content are provided. In the method, distiller's corn oil is treated with a mixture including an alcohol to result in a low-free fatty acid oily phase and an alcohol phase. The mixture may also include an alkali. The alcohol may be a monohydric alcohol and an aqueous alcohol, such as an aqueous alcohol having a concentration of at least about 15% alcohol-by-weight. The low-free fatty acid phase may include oil and at least one impurity. The low-free fatty acid phase may be cooled, and the oil may be separated from the at least one impurity using membrane filtration.
