This study was primarily focused on the supercritical fluid extraction (SFE) of cherry seed oil and the optimization of the process using sequential extraction kinetics modeling and artificial neural networks (ANN). The SFE study was organized according to Box-Behnken design of experiment, with additional runs. Pressure, temperature and flow rate were chosen as independent variables. Five well known empirical kinetic models and three mass-transfer kinetics models based on the Sovová’s solution of SFE equations were successfully applied for kinetics modeling. The developed mass-transfer models exhibited better fit of experimental data, according to the calculated statistical tests (R2, SSE and AARD). The initial slope of the SFE curve was evaluated as an output variable in the ANN optimization. The obtained results suggested that it is advisable to lead SFE process at an increased pressure and CO2 flow rate with lower temperature and particle size values to reach a maximal initial slope.

AbstractStudy ascertained the recovery of β-carotene from enzyme-treated (enzyme load of 167 U/g) pericarp of ripe bitter melon using supercritical fluid extraction (SFE) technique. Effect of different pressure (ranged from 150–450 bar), carbon dioxide (CO2) flow rates (ranged from 15 to 55 ml/min), temperatures (from 50 to 90 °C), and extraction periods (from 45–225 minutes) were observed on the extraction efficiency of β-carotene. Results showed that extraction pressure (X1) among extraction parameters had the most significant (p < 0.05) effect on extraction efficiency of the β-carotene followed by allowed extraction time (X4), CO2 flow rate (X2) and the temperature of the extraction (X3). The maximum yield of 90.12% of β-carotene from lyophilized enzymatic pretreated ripe bitter melon pericarp was achieved at the pressure of approx. 390 bar, flow rate of 35 mL/min, temperature at 70 °C and extraction time of 190 min, respectively. Based on the accelerated storage study the 70% retention shelf life of the β-carotene into extract was estimated up to 2.27 months at 10 °C and up to 3.21 months at 5 °C.

Supercritical fluid extraction (SFE) is one of the relatively new efficient separation method for the extraction of essential oils from different plant materials. The new products, extracts, can be used as a good base for the production of pharmaceutical drugs and additives in the perfume, cosmetic, and food industries. The aim of this work was to analyze the supercritical carbon dioxide extraction (SC-CO2) of oils from the selected spice plant materials. In this paper the process parameters such as pressure, temperature, solvent flow rate, size of grinding materials, and ratio of the co-solvent were presented for the selected spice plant materials: black pepper, caraway, celery, cinnamon, clove, coriander, daphne, fennel, ginger, hyssop, juniper, lavender, oregano, pennyroyal, red pepper, safflower, sage, turmeric, and vanilla. The values of operating conditions were: pressure from 7.5 to 68 MPa, temperature from 293 to 363 K, solvent flow rate from 0.003 to 30.0 kg/h, and diameter of grinding material from 0.17 to 3.90 mm. The global yield and quality of the extracts all of the plant material investigated, as well as the possibility of their application in the food, cosmetics and pharmaceutical industries were analyzed. The composition of the extracts was wery complex, and in every case the extract was composed of more than 200 components. All the compounds from the CO2 extracts were classified in the following groups: monoterpene, sesquiterpene, oxygenated monoterpene, and oxygenated sesquiterpene and other hydrocarbon groups. In some of the systems investigated the different mathematical models (Sovová, Hong), which have taken from the literature, were used to correlate the experimental data.

Supercritical fluid extraction (SFE) of lycopene from freeze-dried tomato pomace(peels and seeds) with CO2 was explored. The effect of different technical parameters, such as temperature (40°C, 50°C, 60°C), pressure (35MPa, 40MPa, 45MPa) and particle size (three degree index), on the extraction yield and the content of lycopene in extracts was determined with statistical analysis.The product obtained by supercritical CO2 extraction at over 35MPa contained the highest concentration of lycopene, while the product rich in β-carotene and lutein was obtained at below 30MPa.The product obtained by supercritical CO2 extraction at 40MPa and 60°C contains the highest concentration lycopene of 32.52±1.02g/100g dry material.

Background: Mariposa Christia Vespertilionis (L.) (MCV) Bakh. f. is a plant, commonly known as Mariposa or ‘butterfly wing’ due to the shape and color of its leaves which is similar to a butterfly. MCV has been known to be used as a treatment for many diseases such as tuberculosis, bronchitis, inflamed tonsils, colds, muscle weakness and poor blood circulation. Methods: Supercritical Fluid Extraction (SFE) is the latest equipment that can be used for the extraction of MCV leaves. SFE is the process of separating one component from another by using supercritical fluids as the extraction media. SFE is widely used in extraction due to its environmental friendly process compared to conventional extraction technique. Objective: The aim of this study was to obtain the most optimum conditions in terms of temperature, pressure and particle size in achieving the highest amount of yield in the MCV plant extract. Thus the manipulated parameters for this study were Temperature (T), Pressure (P) and Particle Size (S) where the ranges used were: temperature, T (°C): 30, 40, 50, 60, 70, pressure, P (bar): 150, 200, 250, 300, 350, and particle Size, S: 63 µm, 125 µm, 250 µm, 500 µm and 1 mm. Results: To obtain the optimum condition of yield, Response Surface Methodology (RSM) was used. For the RSM design of experiment, 20 samples were run throughout this experiment. Conclusion: The optimum parameter values generated from the RSM were 39°C for temperature, 202 bars for the pressure and 500 μm for the particle size with the yield of 7.9 %. Actual validation runs were carried out and the percentage error was 14 %.
