Given the great interest in utilizing CO 2 as the solvent for oil extraction, this research selected supercritical CO 2 extraction for oil extraction from spent coffee grounds. Additionally, our laboratory has a pilot-scale supercritical CO 2 extractor with a large reactor volume (5 l). Thus, it has the potential to produce up to several times
3.2 Microwave-assisted extraction (MAE) method 3.2.1 Varying duration. Results in Table 1 show the increase in percentage oil extracted for each experimental run. It is important to note that the ‘Extraction Duration’ is presented with an additional 2.5 min to account for the ‘warm-up’ phase and these total durations are used for energy consumption calculations.
Optimization of coffee oil extraction from spent coffee
Thus, as coffee oil containing less than 1 wt% FFA content was extracted from DSCG when hexane was used, hexane should be chosen in terms of achieving the highest yield and a higher quality of extracted oil.

Supercritical carbon dioxide (SCCO2) extraction was applied for recovering non-polar compounds in spent coffee grounds (SCGs) before enzymatic hydrolysis was performed. The SCCO2 extracted oil yield of 11.93 wt% was observed at 30 MPa and 50 °C. The detectable volatile compounds in SCGs oil were aldehydes and flavor compounds classified as furans. Although the degree of hydrolysis of SCGs
Spent coffee ground oil as a valuable source of epoxides
A CEM EDGE extractor (CEM Corporation, Matthews, NC) was used for large-scale oil extraction. For each run, 5.5 g of freeze-dried SCG were placed in each CEM extraction thimble then heated to 140 °C and held for 5 min in the presence of petroleum ether, with the pressure increasing up to 120 psi.
Highlights We studied the effect of solvents on spent coffee grounds oil extraction. The effect of reaction conditions on the conversion of the oil to methyl ester. The highest extraction yield obtained when using hexane as a solvent. The properties of the extracted oils vary depending on the extraction solvent. The conversion is enhanced by increasing MeOH–KOH/FFA ratio, time and temperature.
Effect of Solvent Extraction Parameters on the Recovery of
Spent coffee grounds (SCG) are a potentially valuable source of lipids for sustainable production of biofuels. However, there are several feedstock properties and solvent extraction parameters that can impact on the oil yield and quality, potentially reducing the possible environmental benefits of deriving oils from this waste stream. This study presents results of laboratory and pilot plant
The lipid fraction of the coffee bean. K. Speer I. Kölling-speer. Agricultural and Food Sciences, Environmental Science. 2006. TLDR. The influences of typical processes like roasting and steaming on selected lipid components as well as the effects of the storage of green coffee beans under different conditions will be described.

Optimization of Coffee Oil Extraction from Defective Beans
As a result, different oil yields with different key volatile aroma compounds concentrations were obtained and it was found that the optimum conditions for extraction were a temperature of 50 °C, pressure of 30 MPa, and ethanol (g) to roasted coffee (g) ratio of 1:1 to obtain 6.50% (w/w) coffee oil yield. Key volatile aroma compounds
The coffee oil extraction was carried out using n-hexane as the solvent. Heating and ultrasonication were included in the oil extraction phase of the experimental work to reduce the duration of chemical reactions. The maximum yield of coffee oil extraction that could be achieved was 8.9% with 66% solvent recovery.
