During the process of aqueous extraction of phenolic compounds, I got a mucilage that must be separated from the extract that I would like to study. Thank you for your help.
You can precipitate the mucilage with ethanol at a low temperature, similar to the methodology of article

Specifically in this part:
The supernatant was again precipitated with the addition of cold absolute ethanol to a final concentration of 80% (v/v) and kept at 4 °C overnight. The resulting precipitation was vacuum concentrated and freeze dried, yielding Grifola frondosa heteropolysaccharide (GFP).
