  • Process for separating a triglyceride comprising a docosahexaenoic acid residue from a mixture of triglycerides
    Patent number: 6399803
    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.
