Supercritical carbon dioxide (SC-CO2)was employed to extract omega-3 rich oil from Sacha inchi seeds and partially defatted cake. For ground seeds, the supercritical extraction was carried out at temperatures of 40, 50 and 60 ◦C and pressures of 300 and 400 bar, and for the cold pressed partially
defatted cake, the extraction was carried out with 300 bar at 40 ◦C and with 400 bar at 60 ◦C. The
global extraction yields (X0), oil solubility, fatty acid composition of the oil and tocopherol content were
determined. The seed samples used in this work contained 54.3% oil, of which 50.5% was linoleinc acid
(-3). The maximum extraction recovery for the seeds as 92% at 400 bar and 60 ◦C, but on one occasion a
recovery of 99.1% oil was obtained when cold pressed extraction was employed, followed by supercritical
extraction at 400 bar and 60 ◦C. A high tocopherol content of about 2–3 g/kg of oil was obtained.
