“…According to Aydi et al. [ 17 ] the yield of Tunisian Pistacia lentiscus leaf oil using the supercritical CO 2 extraction technique varied between 0.093% and 0.285%. It is well known that the quantity of the yield from supercritical CO 2 extraction is affected by several operating conditions such as the CO 2 pressure, CO 2 mass flow rate, time of extraction, and average particle size.…”

Plant materials have been used in different fields such as therapeutics, cosmetics, and energy for ages. Several studies have investigated seeds, whether common or not, in order to ensure a better valuation of natural resources. Among these, Pistacia atlantica Desf. has been the subject of several works on its characterization and valorization. Among the current trends in sustainable development and environmental protection, valorizing natural wild plants via green chemistry has become prevalent. One of these plants, Pistacia atlantica Desf., is a tree that grows in arid and semi‐arid areas, notably in Tunisia, and produces seeds rich in oil. In this study extracting the oil from its seeds is tried by three methods (supercritical carbon dioxide (CO2), pressure, and hexane), and the efficiency of these extraction processes is compared in order to obtain the best yield and maximize its valorization in a variety of industrial fields. The obtained oil is found to be rich in polyunsaturated fatty acids, namely linoleic and oleic acids, with a similar acidic composition among all extraction methods. The tocopherol composition of the oil is determined using high performance liquid chromatography. The total polyphenol content is determined using the Folin‐Ciocalteu colorimetric analysis method. The results show that the seed oil of Pistacia atlantica Desf. extracted by supercritical CO2 gives the highest extraction yield (25%) and the lowest acidity and peroxide values with a high degree of oxidation at 232 and 270 nm. This method also gives the highest content of alpha, gamma, and delta tocopherol as well as total phenolic content compared to the other extraction methods. The composition of chlorophylls and carotenes in the seed oil of Pistacia atlantica Desf. is determined. Besides, the analysis of the sterol composition reveals that β‐sitosterol is still prevailing. Among all the tested extracts, the supercritical CO2 extract demonstrates the best antioxidant performance against the tested radicals. The oil extracted by supercritical carbon dioxide (CO2) is of a higher quality compared to that extracted by pressure and by hexane. Practical applications: The Pistacia atlantica Desf. oil exhibits interesting physicochemical and biological characteristics. The type of extraction affects the quality of the major and minor components in the seeds. However, the supercritical CO2 method produces a better oil quality with the presence of antioxidants such as tocopherols and polyphenols. In fact, it is found that the oil extracted by the three methods has an important sterolic profile with the predominance of β‐sitosterol. According to the classification of vegetable oils, unsaturated fatty acids of atlas pistachio oil can be categorized as oleo linoleic oil, which enhances its nutritional value. Having these characteristics, the use of this oil can be considered in agrifood products.

“…[158] Aydi et al reported that the lowest production costs for Pistacia lentiscus oil extracted using SC-CO 2 were obtained at the higher volume of production. [159] Johner and team calculated the payback time to be shorter than one year, for pequi oil using SC-CO 2. This is interesting in terms of rapid recovery of initial investment.…”

Supercritical carbon dioxide (SC-CO 2 ) extraction is projected as one of the most viable alternatives to conventional hexane extraction due to its density-dependent solvent power, low viscosity, moderately high diffusion coefficient, and low-temperature operative conditions. Demands for retention of bioactive compounds in oils like wheat germ oil, rice bran oil, almond oil, etc., are increasing and that can be easily met up by this alternative solvent. Solvent extraction of oils rich in polyunsaturated fatty acid, like flaxseed oil, microbial oil, etc., is highly sensitive. Prolonged heating during removal of solvent often leads to degradation of essential fatty acids. As the phase change is done by changing the pressure, the use of SC-CO 2 overcomes such issues. It is quite evident that degumming, one of the processing steps in refining of vegetable oils, will not be required if SC-CO 2 is used for extraction. Moreover, in some other cases, bioactive compounds will be retained in the de-fatted meal and can be recovered with better purity. All these factors will add to the overall economy. A detailed review of the application of SC-CO 2 for the extraction of vegetable oils-the initial reports, current status, and future prospectsis presented in this paper. Practical applications:In recent years, the oils and fats industry has gone through several technological advancements and the most important of them was shifting to physical refining process from highly polluting chemical process. The industry may see another major change in the extraction process in the near future. Hexane has been enlisted as a hazardous air pollutant as per the Clean Air Act, 1990. Recent reports show that hexane may have some role even in ozone layer depletion. Scientists are looking forward to alternatives. SC-CO 2 has emerged as one of the most suitable alternatives. The large capital investment required for the installation of SC-CO 2 -based extraction plants was a major drawback. However, ready availability of critical machineries and advancements in terms of automation has brought down the capital expenditure significantly. The utilization of superior quality by-products generated by the process of SC-CO 2 extraction may be an added advantage for the overall economy of the process.

“…SCE uses supercritical carbon dioxide generated at critical conditions of 38 °C and 73.8 bar to extract a wide range of bioactive compounds, with the ability to preserve thermolabile compounds which can undergo degradation at high temperatures, since intensive heating is not required in this method (Nejad‐Sadeghi et al ., 2015). The carbon dioxide pressure, carbon dioxide mass flow rate, extraction time and particle size are considered four vital variables affecting the efficiency of SCE (Aydi et al ., 2020).…”

Summary Berberis species are known for their functional and nutraceutical properties. For example, different Berberis species have shown a wide range of pharmacological activities and they have been used in food industries as additives, preservatives and antioxidants. The functional property of any herb is influenced by many factors including the extraction process of its active components. Consequently, new extraction methodologies have been investigated to increase the efficiency of extracting bioactive compounds. In this review, we examine all the recent extraction techniques and advanced technologies that have been applied for the extraction of phytochemicals from different Berberis species. The five following techniques have been included for this purpose: ultrasound‐, microwave‐, pulsed electric field‐assisted, supercritical carbon dioxide and subcritical water extraction. These techniques have been used to extract phenolics, flavonoids, anthocyanins and berberine from different parts of various Berberis species which include B. vulgaris, B. jaeschkeana, B. aristata, B. integerrima, B. dasystachya and B. koreana. Microwave‐assisted extraction (MAE) has been well studied, optimised and evaluated. Yet, the present research considering other techniques are limited, and require further investigation and optimisation. In addition, the application of green solvents such as natural deep eutectic solvents could be considered in further developing MAE.
