Resumen

En el presente estudio se llevó a cabo la extracción con dióxido de carbono supercrítico (CO₂) de aceites de semillas de Simarouba gluaca en diversas condiciones de presión (300–500 bar), temperatura (50–70 °C) y el caudal de CO₂ (10–30 g·min^-1). La condición de extracción para obtener el máximo rendimiento de aceite se obtuvo a una presión de 500 bares, una temperatura de 70 °C y un caudal de CO₂ de 30 g·min^-1. Al aceite extraido se determinó sus propiedades fisicoquímicas y se comparó con las del aceite extraído con disolvente convencional. Una observación interesante es la reducción significativa del contenido de fósforo (8,4 mg·kg^-1) del aceite extraído utilizando CO₂ supercrítico en comparación con el del aceite extraído con disolvente (97 mg·kg^-1). Además, el contenido de tocoferol total en el aceite extraído supercríticamente (135,6 mg·kg^-1) fué más elevado que el extracto con disolvente (111 mg·kg^-1). El resto de las propiedades físico-químicas de dos aceites extraídos de forma diferente se equipararon entre sí. Los resultados indicaron los posibles beneficios de la extracción con CO₂ supercrítico sobre la extracción con disolvente del aceite de semilla Simarouba gluaca.
