| abstract |
The invention relates to a method for the purification of a first polyunsaturated fatty acid, from an initial mixture, where this initial mixture comprises at least a second fatty acid, in addition to the first polyunsaturated fatty acid, wherein the The method comprises: - at least one stage of liquid phase chromatographic separation of the first polyunsaturated fatty acid and the second fatty acid, which serves as a means to recover, on the one hand, a stream enriched in the first polyunsaturated fatty acid and, on the other hand, a stream enriched in the second fatty acid; - a processing step to treat the enriched stream in the first polyunsaturated fatty acid, which leads to a reduction in the peroxide value and / or the anisidine value of this stream. The invention also relates to a system suitably adapted for the implementation of said method. |
