Response surface methodology was used to determine the effects of solvent flow rate (2, 3 and 4 g/min), pressure (30, 37.5 and 45 MPa), temperature (40, 50 and 60 degrees C), and co-solvent concentration (0, 1.5 and 3 wt% ethanol) on oil yield of apricot (Prunus armeniaca L.) kernel oil in supercritical carbon dioxide (SC-CO2). All the parameters had significant effects on oil yield as well as the interactions between solvent flow rate and pressure, and between pressure and temperature. Oil yield increased with increased parameters. The oil yield was represented by a second-degree polynomial equation. The maximum oil yield from the response surface equation was obtained as 0.26 g/g kernel for 15 min extraction of 5 g apricot kernel particles (particle diameter < 0.850 mm) with 4g/min solvent flow rate containing 3 wt% ethanol at 45 MPa and 60 degrees C. The response surface equation predicted the experimental oil yield with a 10% error. The fatty acid compositions of apricot kernel oils extracted with SC-CO2 and hexane were similar.

Response surfaces of hazelnut oil yield in supercritical carbon dioxide Ozkal, SG; Yener, Meryem Esra; Salgin, U; Mehmetoglu, U (Springer Science and Business Media LLC, 2005-01-01) Response Surface Methodology was used to determine the effects of solvent flow rate (1, 3 and 5 g/ min), pressure (300, 375 and 450 bar) and temperature (40, 50 and 60 degreesC) on hazelnut oil yield in supercritical carbon dioxide (SC-CO2). Oil yield was represented by a second order response surface equation (R-2 = 0.997) using Box-Bhenken design of experiments. Oil yield increased with increasing SC-CO2 flow rate, pressure and temperature. The maximum oil yield was predicted from the response surface equ...
Supercritical carbon dioxide extraction of hazelnut oil Ozkal, SG; Salgin, U; Yener, Meryem Esra (2005-07-01) Solubility of hazelnut oil in supercritical carbon dioxide (SC-CO2) was determined at 15-60MPa, and 40-60 degrees C. The crossover pressure of hazelnut oil was between 15 and 30MPa. The solubility increased with pressure, but increased with temperature above the crossover pressure. Hazelnut particles (1-2 mm) were extracted at 30-60MPa, and 40-60 degrees C with SC-CO2 flow rate of 2 ml/min. Extraction occurred in two periods. The released oil on the surface of particles was extracted in the fast extraction ...
Supercritical carbon dioxide extraction of flaxseed oil: Effect of extraction parameters and mass transfer modeling ÖZKAL, SAMİ GÖKHAN; Yener, Meryem Esra (2016-06-01) Supercritical carbon dioxide (SC-CO2) extraction of flaxseed oil was performed and effects of process parameters including particle size (mean particle diameter <0.85-0.92 mm), solvent flow rate (2-4 g/min), pressure (40-60 MPa) and temperature (50-70 degrees C) were investigated. The broken and intact cells (BIC) model was used for mass transfer modeling of the extraction of flaxseed oil with SC-CO2 successfully. Extraction of flaxseed oil was divided into two periods as first (fast) and second (slow) extr...
Mass transfer modeling of apricot kernel oil extraction with supercritical carbon dioxide Ozkal, SG; Yener, Meryem Esra; Bayindirli, L (2005-09-01) Effects of process parameters on extraction of apricot (Prunus armeniaca L.) kernel oil with supercritical carbon dioxide (SC-CO2) were investigated. The parameters included particle size (mean particle diameter < 0.425-1.5 mm), solvent flow rate (1-5 g/min), pressure (300-600 bar), temperature (40-70 degrees C) and co-solvent concentration (up to 3.0 wt.% ethanol). The model of broken and intact cells represented the apricot kernel oil extraction well. Grinding was necessary to release the oil from intact ...
Subcritical (carbon dioxide plus ethanol) extraction of polyphenols from apple and peach pomaces, and determination of the antioxidant activities of the extracts Adil, I. Hasbay; Cetin, H. I.; Yener, Meryem Esra; Bayındırlı, Alev (2007-11-01) The effects of pressure (20-60 MPa), temperature (40-60 degrees C), ethanol concentration (14-20 wt.%) and extraction time (10-40 min) on subcritical (CO(2) + ethanol) extraction of polyphenols from apple and peach pomaces (moisture content congruent to 14%, particle size = 0.638 mm) were determined. All variables increased total phenolic contents (TPC) and antiradical efficiencies (AE) of the extracts significantly (p <= 0.05). The optimum pressure and temperature were 54.6-57 MPa and 55.7-58.4 degrees C f...
