Extractions were carried out at different pressure, temperature and flow rate to analyze the influence of these variables on the extraction kinetics and the oil quality obtained. Extraction curves are initially linear with a slope close to the oil solubility value in supercritical CO2. Based on these results a mathematical model was successfully applied to describe the extraction curves. Characterization of supercritical crude corn oil was performed by determining some physical parameters such as refraction index, density and color. Additionally, the fatty acid composition, neutral lipids, the content of tocopherols, acid index, peroxide value, antioxidant capacity and the oxidative stability were determined in the corn oil extracted. Fatty acid composition was compared with that for crude germ oil and no significant differences between the oils extracted by both methods were found. Oxidative stability test using the Rancimat showed that supercritical CO2 extracted corn oil is less protected against oxidation than n-hexane extracted oils. application/pdf eng Elsevier The Journal of Supercritical Fluids. 2012, V. 72, p. 270–277 http://dx.doi.org/10.1016/j.supflu.2012.10.001 Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Supercritical fluid extraction Corn germ oil Tocopherol Sovová’s model Food Chemical engineering Alimentos Ingeniería química Supercritical fluid extraction of corn germ oil: Study of the influence of process parameters on the extraction yield and oil quality info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion CC-LICENSE license_rdf license_rdf application/rdf+xml; charset=utf-8 805 https://riubu.ubu.es/bitstream/10259/4338/8/license_rdf 4460e5956bc1d1639be9ae6146a50347 MD5 8 THUMBNAIL Rebolleda-JSF_2012.pdf.jpg Rebolleda-JSF_2012.pdf.jpg IM Thumbnail image/jpeg 4023 https://riubu.ubu.es/bitstream/10259/4338/7/Rebolleda-JSF_2012.pdf.jpg ec5c6d24f9fe45f1663acc69651f5377 MD5 7 ORIGINAL Rebolleda-JSF_2012.pdf Rebolleda-JSF_2012.pdf application/pdf 296410 https://riubu.ubu.es/bitstream/10259/4338/1/Rebolleda-JSF_2012.pdf c450f8c38debd2afceb83104f4663aa4 MD5 1 LICENSE license.txt license.txt text/plain; charset=utf-8 998 https://riubu.ubu.es/bitstream/10259/4338/5/license.txt aa90105e1c90a1b4fe810649aa967b7d MD5 5 TEXT Rebolleda-JSF_2012.pdf.txt Rebolleda-JSF_2012.pdf.txt Extracted text text/plain 44985 https://riubu.ubu.es/bitstream/10259/4338/6/Rebolleda-JSF_2012.pdf.txt 01dac135e379bb891ef5e7a599207b86 MD5 6 10259/4338 oai:riubu.ubu.es:10259/4338 2022-04-29 14:02:45.748 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
