“…The final NPV is calculated as positive (1.05×10 7 US$ after 10 years) and the required period to recuperate the initial investment (payback) is 6.2 years, i.e., 8.42 years if the construction period is considered. Consequently, even under different design and operating conditions the NPV and payback period values are in accordance with the results found in similar works ( Kayathi et al, 2020 , 2021 ). Overall, the studied extractive process may be considered economically feasible since the operating conditions and process performance are maintained.…”

“…Studying different types of solvents to evaluate the extraction and subsequent recovery of the compounds of interest is very important, since the chemical characteristics of each solvent act on the matrix, recovering more or less compounds according to their characteristics, such as ionic strength, matrix composition, hydrogen-bond interactions or channel effect. It was supported by using supercritical fluid extraction (Jesus et al, 2010;Kayathi et al, 2021), deep eutectic solvente (Niawanti & Zullaikah, 2017;Zullaikah et al, 2019) or with conventional solventes (Wangdee & Onsaard, 2018;Daisuk & Shotipruk, 2020;Phan et al, 2020). Daisuk & Shotipruk (2020) developed an effective procedure for the recovery of γ-oryzanol through calciuminduced precipitation (Ca) of the raw material of RBO (RBOS), a by-product of the RBO industry, where one of the studied variables was the type of solvent used in extraction (chloroform, DCM, acetone, ethyl acetate, furfural, isopropanol, hexane, ethanol and methanol).…”

SummaryThe aim of this work was to develop an extraction method to recover γ‐oryzanol and tocopherols from the distillation residue of the fatty acids generated during the neutralisation step of the rice bran oil refining process. The phytochemicals extraction was performed with different solvents (chloroform, methanol, methyl ethyl ketone and acetone) at a ratio of 10:1 v/w (solvent: sample), by agitating the mixture for 10 min at room temperature (20 °C ± 2 °C), then stored at −18 °C for 15 h. The γ‐oryzanol and tocopherol content in the extracted fractions were concentrated and quantified using reverse phase high‐performance liquid chromatography coupled with UV–vis and fluorescence detector, respectively. It was observed that only one step of extraction with methanol resulted in an increased concentration of tocopherols for about six times, with a recovery of 51.50%. However, using two stages of extraction, the mixture of methanol and methyl ethyl ketone (1:1, v/v) allowed the recovery of 92.15% of tocopherols and 84.12% of γ‐oryzanol, increasing the initial concentration of these phytochemicals in about three times. These results show that there is a great possibility of these phytochemicals recovery from the distillation residue from fatty acid recovery.

“…Extraction using SC-CO 2 is a valuable tools, empowered by overcoming the destitute solvent nature of CO 2 through increased additives [67][68][69][70]. SC-CO 2 extraction has pulled in impressive consideration in recent years as a hopeful elective to ordinary solvent extraction it offers a number of benefits, counting an absence of solvent remainder and better conservation of aromatic compounds [71][72][73][74][75]. Various studies have been conducted to determine the suitability of extracting bioactive compounds using SC-CO 2 process.…”

Supercritical carbon dioxide (SC‐CO2) is CO2 that is stored beyond its critical point of 7.4 MPa and 31.1 °C. Given the request for consumption of a green solvent for the environment, SC‐CO2 is widely utilized in chemical, food, and pharmaceutical industries. To design material and drug production processes using supercritical fluid (SCF) technology, knowledge of their solubility is important. Temperature and pressure are the main factors in the study of solubility. Solubility data are then evaluated using equation of state, semi‐empirical, and intelligence models to establish suitable correlations. SC‐CO2 is one of the most important materials used in SCFs to study solubility. Another application of SC‐CO2 is in the field of material extraction to reduce the consumption of organic solvents. Nanoparticles production in drug industry is another advantage of SC‐CO2. Micro and nanoparticles can be produced using SCF techniques. In this review, the applications of SC‐CO2 in drug solubility, extraction of valuable materials, and nanoparticles production for pharmaceutical processes are reported and discussed. Finally, the main challenges are explained.
