Supercritical CO2 extraction of lipids and astaxanthin from Brazilian redspotted shrimp waste (Farfantepenaeus paulensis)

▶ Recovery of 64% of lipid. ▶ Recovery of 39% of astaxanthin. ▶ The oil is fractionated with scCO2 and DHA was easier to fractionate than EPA. ▶ Pressure and temperature had only a slight effect on the lipid extraction yield. ▶ Pressure and temperature had a significant effect on the astaxanthin extraction yield.
