SFE provides a rapid and quantitative method for extracting essential oils.

the hydrodistillation extracts were light yellow, while the SFE extracts were dark green indicating the extraction of chlorophyll along with the essential oils.

you can find more differences in the attached file

Nor Azah Mohamad Ali

SFE will mostly produce extracts rather than oils, but sometimes you may get oils with the right parameters. You may be able to increase the percentage of certain chemical compounds, higher yields with SFE compared to normal distillation.
