METHOD OF DHA ENRICHMENT USING PRESSURIZED CARBON DIOXIDE

摘要

The present invention relates to a method of obtaining fatty acids with a concentrated DHA comprising: a) a step of converting oil containing DHA into fatty acids; b) a step of manufacturing a mixed solution of the fatty acids obtained in step a) and ethanol; c) a step of adjusting an initial moisture content of the mixed solution at a range of 0-5 wt%; d) a step of adding 2.5-10 wt% of enzymes to the mixed solution obtained in step c); e) a step of injecting carbon dioxides at a pressure of 2.8-13.8 MPa into a reactor; f) a step of performing a reaction for 2-24 hours while performing stirring; and g) a step of obtaining reactants by lowering pressure to atmospheric pressure while slowly exhausting carbon dioxide from the reactor.
