Extraction of passion fruit seed oil using supercritical CO₂: a study of mass transfer and rheological property by Bayesian inference

Abstract

SUMMARYExtraction of passion fruit seed oil using supercritical CO 2 : a study of mass transfer and rheological property by Bayesian inferenceThe extraction of oil from passion fruit seeds using supercritical CO 2 was studied. Experimental data were obtained for extraction conducted at 15, 20 and 25 MPa; at temperatures of 40 and 50 °C with CO 2 flow rates of 1.5 and 3.0 mL min -1 . An increase in the pressure, temperature and CO 2 flow rate increased the yield. The maximum extraction yield obtained was 18.5%. The mass transfer coefficients for passion fruit oil were found to be 8.496 3 10-5 s-1 at 25 MPa, 50 °C and 3 mL s -1 CO 2 flow rate. Dilatant fluid behavior was observed in all tests of the rheological study. KEY-WORDS:Bayesian inference -Passion fruit -Seed oil -Supercritical CO 2 .

Study of supercritical CO2 extraction of tamarillo (Cyphomandra Betacea) seed oil containing high added value compounds

“…On the other hand, pressures around 35 MPa produced a higher extraction yield at 60°C, due to the existence of a “ crossover point ” close to 27.5 MPa, above which, the oil yield increased with the pressure and temperature, predominating the impact of the temperature over the vapor pressure of the solute and consequently on the overall performance . This is consistent with crossover phenomenon reported in the extraction with SC‐CO2 of pomegranate seed oil , nuts , and in the case of extracts from tamarillo epicarp , passion fruit seed oil , and peach seed oil .…”

“…Tamarillo seed oil obtained with SC‐CO2 presented a saturated fatty acid content of 11.80, 16.18% monounsaturated fatty acid content, and 72.05% polyunsaturated fatty acid content, which is similar to those reported in other studies . The high polyunsaturated content is due principally to its linoleic content, as in passion fruit seed oil (72.7%) and grape seed oil (70–78%) . Linoleic acid is characterized as an essential polyunsaturated fatty acid.…”

“…On an experimental level, the maximum oil yield achieved was 17.41% at 38.1 MPa and 50°C, whereas the oil soxhlet (n‐hexane) extract yield 24.05%. Similar yields for were obtained using other sources, such as tomatoes (17.3%) , and passion fruit seeds (18.5%) extracted with SC‐CO2. A higher extraction yield for soxhlet (n‐hexane) than SC‐CO2 was observed.…”

“…The extraction with SC‐CO2 was conducted in a range of 20–38.1 MPa and 40 and 64°C (Table ), 30 g CO 2 .min 1 , solvent/feed ratio (S/F = 22.5 g CO 2 /g seed) and 150 min. The extraction conditions were determined based on various studies conducted regarding the extraction of fruit seed oils .…”

Efecto de la Presión y la Temperatura de Extracción con CO2 Supercrítico Sobre el Rendimiento y Composición de Aceite de Semillas de Guayaba (Psidium guajava)

“…Sin embargo las proporciones encontradas por Castro-Vargas et al (2011), para los demás ácidos grasos difieren a los de este estudio, encontrando un alto porcentaje en ácido esteárico (41,22 %), seguido de ácido palmítico (4,17 %) y ácido oleico (2,84 %). El perfil de ácidos grasos encontrado para aceite de semillas de guayaba en este estudio, es similar al perfil del aceite de semillas de maracuyá reportado por otros investigadores (Liu et al, 2009;Cerón et al, 2012;Cardoso de oliveira et al, 2013).…”
