The pronounced increase in the lipid yields of both configurations
upon pressure ramping demonstrated how a sudden shift
in the fluid solvation power could trigger the solubilisation of lipid
fractions which were insoluble at reduced pressure. The first pressure
change (after 80 min for higher-pressure extraction and after
40 min for lower-pressure extraction) was only carried out when
the lipid yield at the original pressure had reached an asymptote
