The extraction of some organic substances from freezed-dried mackerel powder was performed using supercritical carbon dioxide (SC–CO<SUB>2</SUB>) at 4.9–24.5 MPa and 313 K in a fixed-bed flow extractor. It was found that the rate of extraction was enhanced by raising the pressure. The overall yield of the SC–CO<SUB>2</SUB> extraction was comparable to that of a hot-hexane-extraction from the same material. The SC–CO<SUB>2</SUB> extraction produced glycerides of pharmacologic significance such as icosapentaenoic acid (IPA) and docosahexaenoic acid (DHA) from mackerel. In addition, a kinetic model for extraction with supercritical fluids is described, and is applied to correlate our results obtained in the SC–CO<SUB>2</SUB> extraction of mackerel. This model could express the transport within the solid in the supercritical fluid extraction process.
