“…Within the PGSS process, the polymer suspension and CO 2 is stacked into the high-pressure cell, which is warmed and pressurized to SC-CO 2 conditions to reach phase equilibrium. PGSS appears a few benefits for the encapsulation of bioactives where both the divider material and the bioactive are dissolvable in CO 2 at its supercritical state [130][131][132][133].…”

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.

“…The same formulation prepared for the spray chilling was used to produce SLMs by Particles from Gas Saturated Solutions (PGSS), following the methodology described by Klettenhammer et al (2022) with small changes. In addition, a control formulation formed only by the carrier materials was produced to obtain a comparison parameter.…”

“…For example, Fadini et al (2018) used lipid carriers as an outer layer in spray drying particles to deliver sh oil, masking the taste and decreasing the solubility of the particles in water. Klettenhammer et al (2022) used puri ed sun ower wax to encapsulate linseed oil enriched with carrot pomace extract. Spray chilling is an example of microencapsulation technique to obtain solid lipid microparticles.…”

“…The powder presented a very poor owability, with a Carr Index of 48.9 ± 0.2. Klettenhammer et al (2022) founded Carr index values between 12.5 and 25.1 for the linseed oil encapsulated by PGSS with different pressure conditions (10-30 MPa) and sun ower wax (85°C) as wall-material. They observed that particles produced using 10 MPa presented the best ow property with a Carr index of 12.5 ± 0.25%.…”

In this study, cinnamon and paprika oleoresins were encapsulated by two technologies, respectively, spray chilling and particles from gas saturated solutions. Both technologies used palm oil as wall materials. The physical characteristics of the microparticles were compared as well as the oleoresins release behavior in high and low-fat simulated food media. The spray chilling microparticles had an average diameter of 143.7 ± 1.5 µm, spherical shape, smooth surface and passable flow property. In contrast, microparticles obtained by PGSS showed an average diameter of 105.7 ± 0.6 µm, irregular shape, porous surface, poor flow property but higher encapsulation efficiency. In evaluating the compounds released in a simulated food medium, the spray chilling particles delivered 30.7%, while PGSS reached 23.1% after one hour. Both microparticles fitted better to Kosmeyer-Peppas (R2 = 0.98 and 0.96 for spray chilling and PGSS) and Peppas-Sahlin models (R2 = 0.98 and 0.97 for spray chilling and PGSS). However, spray chilling microparticles showed a diffusion mechanism while for PGSS ones erosion was the main mechanism. Despite the different physical characteristics, both microparticles proved to be possible facilitators in delivering oleoresins in food products.

“…In this context, the application of green-based processes-ultrasound-assisted extraction (UAE) with supercritical carbon dioxide-assisted encapsulation-is a potential tool to design and produce natural ingredients from fruit by-product fractions with completely new specifications. This approach follows the principles of Green Chemistry and the Circular and Bioeconomy concept by using discarded biomass to create new or more advanced (semi)products [9][10][11]. UAE, regarded as a non-conventional technology, stands out as a promising alternative for extracting bioactive compounds from plants.…”

The aim of this study was to develop, for the first time, anthocyanin-enriched fractions from black raspberry pomace (BRP) using ultrasound-assisted extraction (UAE) via sonotrode and the Particles from Gas-Saturated Solutions (PGSS) process. UAEs with different amplitudes and sonication times were evaluated and showed relevant effects on the yields of target analytes. The raspberry pomace extracts were formulated in a powder form by PGSS using glyceryl monostearate as a carrier at different extract-to-carrier ratios of 1:11, 1:5, and 1:3. The effects of all variables were evaluated in terms of extraction yield, total phenolic content, and encapsulation yield. UAE was strongly affected by amplitude, and the highest amplitude (100%) provided the best results for extraction yield and total phenolics. HPLC of UAE extracts and powders was utilized for quantification of polyphenol compounds, showing cyanidin-3-rutinoside as a main compound, followed by cyanidin-3-glucoside, rutin, ellagic acid, and gallic acid. These results show that these time-efficient and high-performance techniques enable the production of natural fractions from industrial BRP with acceptable characteristics to be used for the development of nutraceuticals and different food formulations.
