Supercritical extraction of sunflower oil: A central
Supercritical carbon dioxide (SC-CO 2) extraction of sunflower seed for the production of vegetable oil is investigated and compared to conventional methods.The effects of extracting variables, namely pressure, temperatures, particle size, SC-CO 2 flow rate and co-solvent, on SC-CO 2 extraction are investigated. The maximum yield for sunflower oil is found to be about 54.37 wt%, and is
Extraction of sunflower oil from sunflower seeds (Heliantus annuus L.) using supercritical CO 2 was studied.The shrinking core model was applied to the modeling of the packed-bed extraction process. The experimental data were obtained for extraction conducted at the pressures of 20, 30, 40, 50 and 60 MPa; the temperatures of 313, 333 and 353 K, the CO 2 flow rates of 1–4, and 6 cm 3 CO 2 min
Extraction of Oil from Canola Seeds With Supercritical
Supercritical carbon dioxide (SC-CO2) extraction of oil from seed is an alternative process to solvent extraction, hydro distillation and steam distillation because of certain advantage of SC-CO2 with low critical temperature. The extraction of vegetable oils using supercritical carbon dioxide has been studied as a potential alternative to the
Baümler et al. (2016) reported the extraction of oil-insoluble compounds such as sugars, among others, in the extraction with ethanol of sunflower oil from collet and Toda et al. (2016) analyzed
Extraction of sunflower (Heliantus annuus L.) oil
The highest extraction yields of 100 and 87% were obtained in runs 2 and 4, respectively, at a pressure of 25 MPa for both. An increased extraction of sunflower oil with high CO 2 pressure was also reported by Salgin et al. .This effect is due to the increased oil solubility in the solvent with increased pressure, leading to an enhanced extraction yield,.
In this work experimental results of sunflower seed oil extraction using supercritical CO 2 are presented, together with the outcome obtained by applying to the same data a theoretical model recently developed and further improved here.. We performed extraction tests utilizing a supercritical extraction equipment having a volumetric capability of 100 ml; the seeds were milled to obtain
Supercritical fluid extraction of sunflower seed oil
Abstract. The effect of ethanol addition to supercritical carbon dioxide (SC-CO 2), up to 20%, on sunflower seed oil extraction over the range of 150 to 350 bars and 42 to 80°C was studied.A nonrecirculating-made bench-scale system was used as extraction equipment.
A continuous process for the extraction of sunflower oil using supercritical CO 2, featuring multiple extractors, one oil separator and three cascaded CO 2 recovery vessels operating at different pressures, was devised and studied. For every single equipment of the plant making up the process a
Extraction of passion fruit seed oil using supercritical
The 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%.
Supercritical fluid extraction has been widely employed in the extraction of high purity substances. In this study, we used the technology to obtain oil from seeds from a variety of grapes, from vinification residues generated in the Southern region of the state of Rio Grande do Sul, Brazil.
