| Zusammenfassung: | Supercritical CO2 (scCO2) extraction of valuable chemicals from food, biomass, and residues thereof has recently been recognized as a sustainable process. In this study, we present a new design of an attenuated total reflection infrared (ATR-IR) spectroscopic cell for monitoring the extraction of fatty acid from almonds under scCO2 conditions. The newly designed ATR-IR cell allows in situ monitoring of changes of the composition of the almonds during the scCO2 extraction process at a pressure of up to 450 bar. Extracted components can be spectroscopically followed at a time resolution of 30 s. This allows fast and facile optimization of scCO2 conditions such as temperature, pressure, and extraction time. |
