Extraction makes it possible to obtain macerated oils, aqueous extracts, hydro-alcoholic extracts, hydroglycerine extracts and even glycolic extracts.
Plant extraction is a process which aims to extract certain components from plants. This operation separates solids from liquids. In other words, the plant, the solid body, is immersed in a solvent which may be oil, water, alcohol or a mixture of several solvents. The desired plant compounds are then solubilised and captured in the solvent. As a result, we obtain the desired extract.
Extraction by brings together two major processes: Maceration: static process at room temperature or hot with slow infusion Leaching: dynamic process with the continuous circulation of a fluid to deplete the plant Then, at the end of the extraction operation, the plant and solvent are separated by decantation or pressing. The extract obtained is then filtered. Filtration can range from simple clarification of the extract to so-called sterilising filtration, depending on particular needs. The extract can also be pasteurised to eliminate microorganisms and the risk of bacterial contamination.  It is also possible to concentrate the extracts by removing a portion of the solvent.
