    Abstract: This invention is directed to a process for separating a first triglyceride comprising a docosahexaenoic acid residue from a second triglyceride. The process comprises introducing a feed mixture comprising the first triglyceride and the second triglyceride into a chromatographic separation zone, and then isolating a fraction of the feed mixture in the separation zone that has a mass ratio of the first triglyceride to the second triglyceride that is greater than in the feed mixture. The separation zone comprises a stationary phase which comprises metal ions that are capable of coordinating with a double bond of a fatty acid residue of the first triglyceride to form a metal complex with the fatty acid residue.

    Abstract: The invention provides a process for fractionation of compounds which in essentially non-polar solvents form mixed or co-micelles and hence cannot normally be fractionated by membrane filtration. By dissolving a mixture of such compounds in a solvent system in which selective micelles formation occurs, and contacting the solution under pressure with a semipermeable membrane to separate the mixture into a permeate and a retentate, fractionation of the compound mixture can be achieved, i.e. a fraction enriched in one of said compounds can be recovered from the permeate and/or the retentate by removing solvent therefrom. The new process is in particular useful for fractionating phosphatides-containing mixtures into a fraction enriched in phosphatidyl choline by ultrafiltration of a solution of the mixture in a solvent system comprising an essentially non-polar solvent and a polar solvent, e.g. hexane-ethanol, etc., through a semipermeable membrane, and recovering a fraction enriched in phosphatidyl choline from the permeate. A fraction enriched in phosphatidyl inositol can be recovered from the retentate.

    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.
