The supercritical extraction was carried out at a temperature of 60 °C, pressure range of 400-500 bars and CO2 flow of 40-80 g/min. The maximum recovery was 58% in 180 min, favored by increasing the residence time of CO2 in the extraction tank. Subsequently, the process was evaluated at pilot scale reaching a maximum recovery of 60% in 105 min, with a temperature of 60 °C, pressure of 450 bars and CO2 flow of 1270 g/min. The fatty acid composition of the oil was not affected for an extraction period of 30-120 min. The Sacha inchi oil was fractionated with supercritical CO2 to obtain an omega-3 concentrate oil without finding a considerable increase in the proportion of this compound, due to the narrow range in the carbon number of fatty acids present in the oil (16-18 carbons), making it difficult for selective separation. © 2017 CSIC.enghttps://v2.sherpa.ac.uk/id/publication/issn/0017-3495articleCarbonExtractionFatty acidsSupercritical fluid extractionExtraction tanksFatty acid compositionLinolenic acidsOmega-3Sacha inchiSelective separationSupercritical COSupercritical extractionCarbon dioxide2021-03-23Triana-Maldonado, D.M.Torijano-Gutiérrez, S.A.Giraldo-Estrada, C.10.3989/gya.0786161
