“…At a given temperature, increasing the pressure is known to increase the solvent density of supercritical fluids which in turn improves its solvating power. On the other hand, the opposite holds true for temperature (Leila et al, 2022). This is the reason for the reduction of CC at temperatures beyond 60 ℃.…”

“…The surface plot predicts that maximum GY can be achieved at higher levels of temperature and extraction period; the linear effect of both these parameters was highly significant (p<0.0001). Higher temperature increases solute volatility, enhances solubility, and improves extraction efficiency; however, this can also lower the density of SC-CO2 and reduce its solvating power (Leila et al, 2022). Thus, it is important to arrive at a temperature that will increase the solute volatility without compromising the density of SC-CO2.…”

Capsaicin (CC), the dominant pungent compound in hot chilies, is widely used as a flavouring agent, preservative, active compound in packaging film and functional foods. Capsicum chinense cv Bhut Jolokia is one of the richest sources of CC, yet scarcely studied. The present investigation aimed to optimize a clean and green method for extracting CC through supercritical fluid extraction (SFE) method. Low-grade, culled, and discarded fruits were used for the extraction, and process was optimized through central composite design of RSM. The optimized extraction condition, 68.31 ℃/347.98 bars/102.50 min, resulted in maximum CC content (367.14 ± 1.12 mg/g) and oleoresin yield (7.23 ± 2.15 %) in a shorter extraction time (< 2 h). Accelerated thermal stability study suggested first-order degradation kinetics of CC at temperatures from 80 to 140 ℃. The activation energy (kJ/mol) of the reaction was 71.86, while Q10 for 80 to 100 ℃, 100 to 120, and 120 to 140 were 0.0548, 0.0574, and 0.1456, respectively. Valorisation of Bhut Jolokia for targeting an oleoresin with maximum CC opens a new window for its commercial exploitation in food industry. Furthermore, the study opens avenues for exploration of SFE-based extraction as clean, and sustainable method with reduced carbon footing.

“…However, increasing pressure above a certain level could result in a higher solubility of waxes and other hydrocarbons besides essential oil components. Meanwhile, increased temperature at constant pressure decrease the CO 2 density, and reduce the extraction yield though it increases the vapor pressure of the EO [51,52]. The SFE temperature is used in the range 35-50°C to avoid degradation of thermolabile compounds.…”

Essential Oils - Advances in Extractions and Biological Applications

View full text Add to dashboard Cite

Essential oils are formed by a complex matrix of substances that are biosynthesized in the secondary metabolism of plants. Nowadays, different ecofriendly extraction techniques (e.g., ultrasound-, microwave-, enzyme-assisted extraction, and supercritical fluid by CO2, etc.) have been adopted to obtain essential oils. These techniques provide unique quality of essentials oils or extracts from aromatic plants in a short time with high energy savings. Essential oils not only impart aroma, but also possess antimicrobial and antioxidant activities. Health limitations in the use of synthetic additives have drawn researchers’ attention towards essential oils as safe natural preservatives. Therefore, this chapter summarizes novel technologies to recover essential oils or extracts. In addition, it focuses on application of essential oils and their constituents as green preservatives to retard microbial growth and oxidative spoilage.

“…Among the green technologies, supercritical fluid extraction (SFE) using carbon dioxide (CO 2 ) is suitable for thermally labile substances, is very safe to use, and allows the elimination of hazardous substances [16]. CO 2 is a green solvent that is easy to remove from products and is a nonozone-depleting, nontoxic, and nonflammable solvent [17]. CO 2 was used to recover oil or antioxidant phenolic compounds from SCG [18] and other matrices, such as basil leaves [19], citrus peels [20], and walnut husks [21].…”

Spent coffee grounds (SCG) contain bioactive compounds. In this work, given the increasing demand to valorize waste and use green technologies, SCG were submitted to extraction by carbon dioxide (CO2) in supercritical and liquid conditions. The extraction parameters were varied to obtain the maximum yield with the maximum antioxidant activity. The use of supercritical and liquid CO2 with 5% ethanol for 1 h provided yields (15 and 16%, respectively) comparable to those obtained by control methods for 5 h and extracts with high total polyphenolic contents (970 and 857 mg GAE/100 g oil, respectively). It also provided extracts with DPPH (3089 and 3136 μmol TE/100 g oil, respectively) and FRAP (4383 and 4324 μmol TE/100 g oil, respectively) antioxidant activity levels higher than those of hexane extracts (372 and 2758 μmol TE/100 g oil, respectively) and comparable to those of ethanol (3492 and 4408 μmol TE/100 g oil, respectively). The SCG extracts exhibited linoleic, palmitic, oleic, and stearic acids (predominant fatty acids) and furans and phenols (predominant volatile organic compounds). They were also characterized by caffeine and individual phenolic acids (chlorogenic, caffeic, ferulic, and 3,4-dihydroxybenzoic acids) with well-known antioxidant and antimicrobial properties; therefore, they could be used in the cosmetic, pharmaceutical, and food sectors.
