  • DHA ENRICHMENT PROCESS
    Publication number: 20110124728
    Abstract: The present invention relates to a continuous process of DHA enrichment of a solution of fatty acids or derivatives thereof comprising less than 50% of DHA relative to the total fatty acids of the solution or to derivatives thereof, wherein the process comprises the steps of (a) simultaneous countercurrent injection, into a fractionation column, of the flow of the solution of fatty acids or of derivatives thereof and of a flow of supercritical CO2 at a temperature of less than or equal to 70° C. and at a pressure of between 100×105 Pa and 160×105 Pa, wherein the level of supercritical CO2 is between 30 and 70, and (b) recovery of the residue comprising at least 50% of DHA relative to the total fatty acids of the residue or to derivatives thereof, wherein the DHA yield is greater than or equal to 60%.
