- Lyophilization (Freeze Drying): This method is used to remove water from the extract without the need for high temperatures, preserving heat-sensitive compounds.

3. Procedure:
- For evaporation, heat the liquid gently while stirring to promote even evaporation and prevent overheating of the extract.
- Monitor the temperature and the volume of the liquid to determine when the desired concentration is reached.
- For lyophilization, freeze the liquid and then reduce the pressure to allow the ice to sublimate directly into water vapor.

4. Tips for Concentration:
- Be cautious not to overheat the extract, as this can degrade sensitive compounds.
- Use a clean and dry environment to prevent contamination during concentration.

Quality Considerations

- Ensure that the filtration and concentration process does not introduce new contaminants or degrade the quality of the extract.
- Monitor the temperature and pressure carefully, especially during evaporation and lyophilization, to avoid damaging the active components.

Safety Measures
