Licorice extraction processes
Licorice extract is typically made by boiling the dried root of the Glycyrrhiza glabra plant in water and then evaporating the liquid to obtain a concentrated extract.
The following is a general process for making licorice extract:
• Harvesting and Drying: The roots of the Glycyrrhiza glabra plant are harvested and cleaned, and then dried in the sun or using artificial heat.
• Grinding: The dried roots are ground into small pieces or a fine powder to increase the surface area and help with the extraction process.
• Extraction: The ground licorice root is then boiled in water or a mixture of water and alcohol, depending on the desired concentration of the extract. The boiling process extracts the active compounds, including glycyrrhizin, from the licorice root.
• Filtration: After boiling, the liquid is filtered to remove any solid particles and impurities.
• Concentration: The filtered liquid is then evaporated under vacuum at low temperature to concentrate the extract.
• Storage: The concentrated licorice extract is then stored in an airtight container until ready for use.
It is important to note that licorice extract can vary in concentration depending on the desired use and application. Additionally, some manufacturers may use additional processing steps or additives to improve the flavor or texture of the extract. As with any natural product, it is important to purchase licorice extract from a reputable source to ensure quality and safety.
