  • Publication number: 20160272920
    Abstract: Methods for producing oil from fats and oils having high free fatty acid content are provided. In the method, fats and oils are 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. Fats and oils amenable to such a method may include, but are not limited to, waste fats, waste oils, high acid grease, high acid tallow, sorghum heat oil, and corn oil, such as corn oil produced at an ethanol production plant.

  • Publication number: 20160229793
    Abstract: The present invention provides methods of processing lipid materials such as soapstock, wet gums and dry gums. Enzymes are utilized to catalyze hydrolysis of the lipids materials to recover fatty acids. Addition of organic acids and/or polyols improved yield of fatty acids and reduced formation of emulsion. Lipid materials can be formulated with other agricultural products as new value-added animal feed products. Further, a process for concentrating nitrogenous compounds such as choline, inositol, ethanolamine and serine from phospholipid materials obtained as byproducts from vegetable oil refining is provided. The process involves performing hydrolysis of the gum based products in the presence of an alcoholic solvent and acid catalyst. Post hydrolysis, gums breakdown to oil and water phases which are further separated and concentrated. These concentrated products may be further fractionated to concentrate individual nitrogenous compounds.
