“…In another study, the same extraction conditions were applied to extract phytosterol from H. rhamnoides seeds. 78 The optimum pressure and temperature for -sitosterol extraction were 28 MPa and 60 ∘ C for fresh sample, and 60 MPa and 60 ∘ C for stored sample. The yield of -sitosterol from storage seed was lower than that of fresh seed.…”

“…At high temperature, the phytosterol yield was lower since the density of the solvent was dominant over vapor pressure of the solute. In another study, the same extraction conditions were applied to extract phytosterol from H. rhamnoides seeds . The optimum pressure and temperature for β‐sitosterol extraction were 28 MPa and 60 °C for fresh sample, and 60 MPa and 60 °C for stored sample.…”

Phytosterols provide important health benefits: in particular, the lowering of cholesterol. From environmental and commercial points of view, the most appropriate technique has been searched for extracting phytosterols from plant matrices. As a green technology, supercritical fluid extraction (SFE) using carbon dioxide (CO2) is widely used to extract bioactive compounds from different plant matrices. Several studies have been performed to extract phytosterols using supercritical CO2 (SC-CO2) and this technology has clearly offered potential advantages over conventional extraction methods. However, the efficiency of SFE technology fully relies on the processing parameters, chemistry of interest compounds, nature of the plant matrices and expertise of handling. This review covers SFE technology with particular reference to phytosterol extraction using SC-CO2. Moreover, the chemistry of phytosterols, properties of supercritical fluids (SFs) and the applied experimental designs have been discussed for better understanding of phytosterol solubility in SC-CO2.

“…The most widely used supercritical solvent in the food industry is carbon dioxide (CD 2 ), which promotes high extraction efficiency, atoxicity, reduced generation of waste chemicals and high-quality of extracted material (Passos et al, 2010;Sovová, 2012, Sovová et al, 2010. Therefore, the objective of this research was to comparatively analyze the oil quality extracted from two tucumã varieties from the states of Amazonas (Astrocaryum aculeatum) and Pará (Astrocaryum vulgare), obtained using supercritical carbon dioxide.…”

The vast Amazon region has considerable territorial peculiarities and plant species diversity, sometimes from the same botanical family, which can exhibit significant differences in physicochemical properties. From this diversity, two species stand outAmazonas tucumã (Astrocaryum aculeatum Meyer) and Pará tucumã (Astrocaryum vulgare Mart.). The research focus is to analyze, comparatively, these oleaginous fruits, their similarities, particularities and potentials regarding the oil quality extracted from two tucumã varieties from the states of Amazonas and Pará, obtained using supercritical carbon dioxide, under different extraction parameters. The results demonstrate the biometric particularities of each species, highlighting the Amazon fruit, which also showed higher oil yield using supercritical CD 2 extraction. The fatty acid quality and profile aspects of the oils show their unsaturated predominance, considering carotenoid content and how the extraction temperature can influence the nutritional quality of the oils. The statistical analyses indicated that the Amazon tucumã oil is superior to the Pará tucumã oil. However, in terms of added value both oils have potential applications in various industrial segments.Keywords: Tucumã; oil; supercritical. Practical Application:The temperature elevation applied to obtain of the tucumã oils, interfere on the quantity and quality of their unsaturation profile, directly influencing the nutritional quality of these oil. With regards to quantitatively unsaturated fatty acids, as well as total carotenes.

“…Applying a supercritical fluid as an extracting solvent, especially carbon dioxide (CO 2 ), in the supercritical fluid extraction has advantages due to its non-corrosive nature, its non-toxicity and non-flammability properties, and to the fact that it is easily removed from the extracted product. The operation conditions can be controlled reducing the costs with compression (Temelli, 2009;Sovová et al, 2010;Rubio-Rodríguez et al, 2008;Sovová, 2012;Santos et al, 2012).…”

These researches aimed determine the quality parameters, the nutritional profile, and the thermogravimetric and oxidative behavior of Muruci (Byrsonima crassifolia L.) oil obtained by supercritical CO 2 extraction. The results showed an average oil yield of 5.50%. The acidity and peroxide values show good quality and conservation standards, according to the Brazilian legislation. The fatty acid profile indicates a predominance of unsaturated fatty acids with levels above 60%, highlighting the presence of fatty acids omega-6 and omega-9. The thermogravimetric curves showed oil stability at temperatures around 200 °C and exothermic peaks characteristic of mass loss close to 250 °C. The data of oxidative induction time determined by the Rancimat method showed thermal oxidative stability of 20.85 h for the oil obtained. The Fourier transform infrared (FTIR) spectroscopic profile evidenced chemical compounds with predominantly unsaturated structures, confirming its fatty acid profile. Based on the results of the oil analysis, it is possible to recognize the potential of this species in terms of nutritional, functional, and thermo-oxidative stability aspects.
