“…The increased solvent density improves the interaction between the molecules of the solvent SC CO 2 , the co-solvent EtOH and the polyphenol content. The consequent increase in density elevates the diffusivity and solubility [ 36 ].…”

“…Typically, an increase in the solvent flow rate increases the extraction capacity by reducing the external resistance to mass transfer and increasing the chances of intermolecular interactions between the solvent and the solutes (Essien et al, 2020;Molino et al, 2020). Ruslan et al (2018) recovered a higher catechin content (565.38 ppm) from betel nuts at the highest flow rate studied (4 mL/min). However, as noted in a previous study (Ruslan et al, 2015), very high solvent flow rates can substantially reduce extraction yield due to insufficient contact time between the compounds and the extraction fluid (Essien et al, 2020).…”

“…Catechin yield extracted from betel nuts (ground to d p of 177 mm) by SC-CO 2 has been at 565 ppm (mg kg -1 ) (analyzed by HPLC) at optimized conditions of 70 °C, 30 MPa, 5 % methanol as modifier, and a flow rate of 4 mL min -1 of CO 2 [32]. In another study, extraction of catechin from peanut skin by SC-CO 2 yielded 208.73 mg catechin per g sample (HPLC analy-sis) at the extraction conditions of 70 °C, 30 MPa, 180 min, 5 % co-solvent (ethanol), flow rate 3 mL min -1 for CO 2 .…”
