PLE was accomplished at 100 C and 10 MPa, on the basis of a previous work. The influence of pressure (15–30 MPa) and temperature (50 C and 70 C) on the SAS precipitation process was experimentally studied in terms of precipitation yield, concentration of key bioactive compounds (caffeine and monomeric catechins) and total content of phenols of the precipitates. Additionally, a comparison using a different organic solvent (ethanol) for the extraction and precipitation steps is reported.
