| Abstract: | Arachidonic Acid is being taken into account as a kind of human essential fatty acid.AASCO from fermentation was taken as experimental material of richness condition of supercritical CO 2 extraction.This paper studied the influence of extraction condition(temperature,pressure)and separation condition(temperature,pressure)on the richness rate.The optical technique way was determined and the basis for batch process were provided. |
