The scale-up of the supercritical fluid extraction (SFE) process for grape (Vitis vinifera L.) seed was studied from laboratory (0.29 L) to pilot scale (5.15 at 35 MPa and 313 K. criterion adopted consisted maintaining a constant solvent feed ratio (S/F), successfully used predict approximate behavior SFE 17-fold scale-up. Linoleic acid major component extract; palmitic, stearic oleic acids were also detected. economic evaluation showed that it is viable establish plant in Brazil processing...
The increasing global levels of anthropogenic greenhouse gases (GHGs), especially CO2 emissions, have caused environmental problems that impact humanity and the ecosystems. Therefore, gas capture storage are a feasible solution to this issue. Some aqueous amine solutions, such as monoethanolamine (MEA), been used GHGs, but they not environment friendly. Research on greener solvents for task led deep eutectic (DESs) novel option. This review explores applications different DESs; compares...
This work is focused on the use of supercritical carbon dioxide to inactivate pathogenic Escherichia coli. For this purpose, experimental design methodology was employed evaluate effects pressure (8–28 MPa), depressurization rate (1–11 MPa min−1) and cycling (1–5 cycles) microorganism inactivation using static-synthetic method in a variable-volume reactor. The number cycles system showed significant influence E. coli with CO2, indicating that increase improve efficiency. Microbial followed...
This work reports new vapor pressure data of soybean oil, castor and their fatty acid ethyl ester mixtures (FAEE) obtained from an enzyme-catalyzed reaction. Vapor measurements were carried out in a temperature range (290 to 355 K) using static method having differential transducer with precision 5 Pa. Degassing was performed inside the equilibrium cell by freezing thawing samples under moderate vacuum (about 50 kPa). For vegetable oils, values varied (0.19 2.16) kPa, whereas for FAEE...
In this paper, a non-conventional approach of modeling phase equilibrium was applied. An alternative tool, the artificial neural network (ANN) technique has been used for estimating transition pressures two ternary systems at high (CO2 + Biodiesel Methanol) and Ethanol). Temperatures, molar ratios, compositions were utilized as input variables ranges 303.15 to 343.15 K, 4.30 15.62 MPa 0.4 0.99, respectively. The databases taken from literature split into training, validating, testing data....
The present work reports liquid−liquid equilibrium data for the systems containing refined rice bran oil + anhydrous ethanol water hexane at (298.15 ± 0.2) K with mass fractions of (4.14, 9.84, and 14.79) % in (313.15 a fraction 4.40 ethanol. instrumental technique near-infrared spectroscopy allied to multivariate calibration (in this work, termed "NIR method") was used determination phase compositions. To avoid separation sampling system 313.15 K, samples were diluted tetrahydrofuran....
Abstract Studies show that propolis has antimicrobial, antifungal, antiviral, anti-inflammatory, antioxidant, antitumor, and immunomodulatory properties, may protect against diseases such as diabetes, cardiovascular disease, cancer. We aimed to extract compounds of brown with hydroalcoholic solvents evaluate their cytotoxic activity on tumor non-tumor cells by MTT test. tested the solute:solvent ratio (ethanol:water) extraction time in a Shaker incubator (710 rpm) before conducting central...
Abstract The aim of this work was to refine expeller‐pressed crude canola oil by pilot scale liquid–liquid extraction with hydrated ethanol as solvent. Quality indices were determined, and shelf life estimated in the accelerated test. projection performed based on results scale. experimental device operates a batch process 89.6% yield deacidification an average 4.4 contacts per assay. In process, without bleaching deodorization steps, physicochemical parameters according Codex Alimentarius...
Abstract Averrhoa carambola L. presents in its composition diversity of nutrients and vitamins. The present study aimed to extract water fat-soluble compounds from this fruit at different stages maturation (green mature), perform the physical-chemical characterization as well evaluate cytotoxicity against hepatoma cells Rattus norvegicus (HTC). physicochemical results showed that pH molar acidity is influenced by state. presented high percentage moisture, while total minerals (ash) increased...
