“…However, it has been found that the effect of the increase in pressure (1e35 MPa) in extractions which employ pressurized liquids may be insignificant without the combination of other factors such as temperature (Osorio-Tob on, Carvalho, Rostagno, Petenate, & Meireles, 2014). CE extraction yield was higher than ScCO 2 , this behavior was reported in several studies (Barreto et al, 2008;Moura et al, 2012), which also obtained yields for the conventional processes higher than supercritical extraction. However, this conventional overall performance does not differentiate between extraction of functional and non-functional compounds.…”

“…Additionally, due to the fact that supercritical extraction yields are benefited by the increase of density of the solvent and the vapor pressure of the solute as reported by Moura, Prado, Meireles, and Pereira (2012), who obtained high extraction yield at 30 MPa and temperatures between 35 C and 55 C. It was presumed that extraction at 30 MPa/40 C would be ideal for supercritical extraction of mango peel.…”

“…In comparing Soxhlet extraction method to the other methods discussed in this study, it resulted in the highest extraction level because using large amount of solvent (150 ml), which led to a greater solvent/sample ratio and also using long extraction time (Bruno and Ely 1991; Moura et al . 2012).…”

In this work, three extraction methods: Soxhlet, microwave irradiation and ultrasonic irradiation for extraction of lipids from spent coffee grounds were carried out using n‐hexane and petroleum benzene as solvent. Also, supercritical fluid extraction (SFE) using CO2 under different conditions was used for comparison. Different methods of extraction with organic solvents showed significant differences in the extraction yields. However, no significant differences were found when a given method (e.g., microwave irradiation) was applied using different organic solvents. On the other hand, different extraction conditions from the various runs of SFE resulted in significantly different extraction yields, all of which were higher than those of the other extraction methods using organic solvents except the Soxhlet extraction. No significant differences were observed in the fatty acid compositions of the extracted oils using organic solvents. However, the fatty acid compositions of the oils extracted under different conditions of SFE indicated significant differences among several fatty acids. PRACTICAL APPLICATIONS Supercritical fluid extraction (SFE) can be applied as a green technology to the oil extraction of spent coffee grounds (SCGs), as a waste product of the coffee industry, demonstrated in this work. Extraction using supercritical carbon dioxide is a feasible food processing unit operation, and no regulatory hurdles. The extraction yield of oil from SCGs was obtained at 98.14% relative to the Soxhlet extraction. This trend demonstrates that SFE can be a potential candidate for oil production from the waste product of the coffee industry.
