“…In general, the study of modeling SC-CO 2 extraction and rheological behavior have been carried out by a frequentist approach, adjusting nonlinear models, which aim to synthesize pieces of information into parameter estimates to be interpreted (Papamichail et al, 2000;Reverchon 1997;Souza et al, 2008;Meziane et al, 2006;Fiori, 2007;Han et al, 2009;Ixtaina et al, 2010;Corso et al, 2010;Saxena et al, R.

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 .

“…Ramesh et al (1995) emphasize that drying or toasting processes optimize the extraction of oil from oilseeds and may affect the physical-chemical properties of the oil. Saxena et al (2011) reported that the color of the oil extracted with ethanol solvent is a little bit darker than the color of oil extracted with hexane. Works that compare the extraction methods using biorenewable solvent and traditional fossil solvent (hexane) or pressing methods can be found in the literature by Brossard-González et al (2010), Ribeiro et al (2010), Ferreira-Dias et al (2003 and Drumond et al (2006).…”

“…N-hexane can contain from 45 to 70% n-hexanes, as well as methylcyclopentane, 3-methylpentane, 2-methylpentane and cyclonhexane (Hammond et al, 2005;Wakelyn and Wan, 2006). Saxena et al (2011) reported in a study, when comparing the yields of cottonseeds solvent extraction using hexane and ethanol at different temperatures, that higher efficiency was obtained using the renewable source ethanol as a solvent at higher temperatures. Brossard-González et al (2010), when performing extraction with two different solvents (ethanol and hexane) and by pressing of physic nut seeds, concluded that extraction with ethanol as a solvent enabled higher yield when compared to pressing and no difference was found in the composition of the oil when using ethanol and hexane as solvents.…”

The selection of species that accumulate oil with potential for biofuel production has favored advancements in the scientific and technological domains within the Brazilian biofuel program. The equipments and methods used for such selection have always prosecuted the objective of increasing oil extraction. The aim of this paper was to evaluate the yield of oil extracted from five vegetable species -castor oil plant (Ricinus communis), physic nut (Jatropha curcas), soybean (Glycine max), groundnut (Arachis hypogaea L.), and crambe (Crambe abyssinica) with two different moisture contents and using two different solvents, hexane and ethanol. The experimental design was factorial (5 × 2 × 2), in which grains of each of the five vegetable species in two different moisture contents were used for oil extraction. It can be concluded from this study that grain moisture content and solvent type had great influence in determining oil yield; and that hexane extraction was most efficient. J. curcas had the greatest increase of oil yield with 30.70% when performing extraction with grain moisture. The smallest differences between the solvents were found in the species R. communis with 12% of higher efficiency with hexane extraction.

“…Considering the studies that aim to describe the mechanisms and kinetics of the extraction processes, many researchers propose a second-order reaction kinetics for the solid-liquid extraction (Saxena et al, 2011). This kinetic model is obtained from the mass rate transfer balance and it is integrated as represented by the following equation.…”

This study reports experimental kinetic data and modeling for the extraction of oil from kiwifruit seeds by ultrasound-assisted extraction (UAE) with ethanol. The fatty acid profi le, tocopherol and total lipids content in the oil obtained were determined. The variables temperature and ultrasonic power were investigated based on the oil extraction yields using a central composite experimental design. The overall yields obtained were compared to conventional Soxhlet extraction with n-hexane and with ethanol. The extractions presented high extraction rates with overall yield ranged between 19 and 33%, and the extraction yields increased with the temperature. The fatty acid profi le showed a high content of omega-3 fatty acids (63.20%) and the Vitamin E content was 14.97 ± 0.38 mg/100 g oil, with ɤ-tocopherol constituting 49% of the total tocopherol. A secondorder kinetic model was applied to describe the ultrasound extraction process under diff erent conditions. The numerical results were compared with the experimental extraction yields and presented a good correlation. The extraction technique investigated was found to be suitable for extraction of oil from kiwifruit seeds, in which the great potential of kiwifruit oil obtained from UAE was demonstrated.
