SUMMARY:Sacha inchi (Plukenetia volubilis L.) seeds were employed for oil extraction with supercritical CO 2 at laboratory scale. The supercritical extraction was carried out at a temperature of 60 °C, pressure range of 400-500 bars and CO 2 flow of 40-80 g/min. The maximum recovery was 58% in 180 min, favored by increasing the residence time of CO 2 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 CO 2 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 CO 2 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. KEYWORDS: a -linolenic acid; Omega-3; Sacha inchi; Supercritical extractionRESUMEN: Extracción con CO 2 supercrítico de aceite y un concentrado de omega-3 a partir de Sacha inchi (Plukenetia volubilis L.) proveniente de Antioquia, Colombia. Semillas de Sacha inchi fueron empleadas para la extracción de su aceite con CO 2 supercrítico a escala de laboratorio, a una temperatura de 60 °C, entre 400-500 bares de presión y un flujo de CO 2 entre 40-80 g/min, obteniendose una recuperación máxima del 58% en 180 min favorecida por el aumento en el tiempo de residencia del CO 2 en el tanque de extracción. Posteriormente, se evaluó el proceso a escala piloto, alcanzando una recuperación máxima del 60% en 105 min de extracción, a una temperatura de 60 °C, presión de 450 bares y flujo de CO 2 de 1270 g/min, sin afectar la composición de los ácidos grasos del aceite durante un periodo de extracción entre 30-120 min. El aceite de Sacha inchi fue fraccionado con CO 2 supercrítico para la obtención de un aceite concentrado de omega-3, sin encontrar aumento considerable en la proporción de este compuesto debido al estrecho rango en el número de carbonos (16-18 carbonos) de los ácidos grasos presentes en el aceite, lo que dificulta su separación selectiva.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
