Abstract:
The present invention provides a chromatographic separation process for recovering a polyunsaturated fatty acid (PUFA) product from a feed mixture, which comprises: (a) purifying the feed mixture in a first chromatographic separation step using an eluent a mixture of water and a first organic solvent, to obtain an intermediate product; and (b) purifying the intermediate product in a second chromatographic separation step using as eluent a mixture of water and a second organic solvent, to obtain the PUFA product, wherein the second organic solvent is different from the first organic solvent and has a polarity index which differs from the polarity index of the first organic solvent by between 0.1 and 2.0, wherein the PUFA product is other than alpha-linolenic acid (ALA), gamma-linolenic acid (GLA), linoleic acid, an ALA mono- di- or triglyceride, a GLA mono- di- or triglyceride, a linoleic acid mono- di- or triglyceride, an ALA C 1 -C 4  alkyl ester, a GLA C 1 -C 4  alkyl ester or a linoleic acid C 1 -C 4  alkyl ester or a mixture thereof.

Claim (Index 1):
A chromatographic separation process for recovering a polyunsaturated fatty acid (PUFA) product from a feed mixture, which comprises:\n (a) purifying the feed mixture in a first chromatographic separation step using as eluent a mixture of water and a first organic solvent, to obtain an intermediate product; and (b) purifying the intermediate product in a second chromatographic separation step using as eluent a mixture of water and a second organic solvent, to obtain the PUFA product, wherein the second organic solvent is different from the first organic solvent, and wherein the first chromatographic separation step comprises introducing the feed mixture into a stationary bed chromatography apparatus and the second chromatographic separation step comprises introducing the intermediate product into a simulated or actual moving bed chromatography apparatus.
