Callaghan Innovation scientists discuss issues and future perspectives for the processing and production of high value lipids using supercritical fluids. Examples include seed oils, marine neutral lipid extracts and polyunsaturated omega-3 fatty acid concentrates, carotenoid-rich extracts, and phospholipid-rich extracts. 

They look at the use of ultra-high pressures for CO2 extraction, the use of propane and dimethyl ether as an alternative extraction solvent, and semi-preparative supercritical chromatography to produce omega-3 concentrates.
