Extraction, enzyme-based
extraction, supercritical Low environmental
fluid extraction impact
Supercritical fluid extraction (SFE)
SFE employees carbon dioxide (CO2) at its supercritical conditions (T 31°C, 73 atm)
as extractor fluid ensuring a safe, not expensive and eco-friendly extractions.
Selective (co-solvent)
No degradation of thermolabile substances
Key parameters: temperature, pressure, particle size of substrate
that can influence the yield of extraction
WP1: extraction of lipids from CS
No literature data reported the application of SFE on CS, only on spent coffee ground
Several extractions were carried out properly matching temperature and pressure, 15mL/min .
The SF extractor is present at Department of Environmental Science and Policy of the University of
Milan
