Method of enrichment highly purified stearidonic acid form from echium oil

摘要

The present invention relates to (1) a process for the primary esterification reaction of a fatty acid of echinomic acid, lauryl alcohol, candida lucer lipase, and distilled water to obtain an esterification reaction product fraction and residual stearidonate- Producing a fatty acid fraction; (2) separating the remaining fatty acid fraction of the stearidonic acid-containing enchi- rone oil; And (3) Secondary esterification reaction is carried out by mixing the residual fatty acid fraction of the echinomic acid-containing stearidonic acid, ethanol and liposomes RM IM to obtain an esterification reaction product fraction and an enriched stearidic acid-enriched oil / RTI (4) a step of separating the remaining fatty acid fraction of the echinomic oil in which the stearidonic acid is concentrated, and a method of recovering stearidonic acid from the echinomic oil.
