The supercritical fluid extraction of chlorophyll and carotenoids from marine algae
Fucus Vesiculosus and Laminaria Digitata with carbon dioxide is studied. Carotenoids
can be completely extracted by pure CO2 during 20 min at 250 atm and 80 °C. To obtain
extracts with high content of chlorophylls, the addition of 10—15% vol. ethanol (polar
co-solvent), or prolonged extraction (50—90 min) at ethanol concentration < 5% vol.
are required.
