The soaking time, temperature, and solvent concentration should be controlled according to the process requirements to fully extract the active ingredients from the licorice roots.
  3. Filtration and Concentration: The soaked liquid is filtered to remove solid impurities, then concentrated to remove most of the water, yielding a concentrated solution.
  4. Precipitation and Separation: The concentrated solution undergoes appropriate treatment for precipitation and separation, removing insoluble substances and impurities.
  5. Refining: The separated extraction liquid is refined using various techniques to eliminate remaining solvents and impurities, enhancing the purity of the extract.
  6. Drying: The refined extract is dried, typically using spray drying or vacuum drying methods, converting it into a powdered form.
  7. Quality Inspection and Packaging: The dried licorice extract undergoes quality testing, including appearance, ingredient concentration, and microbial indicators, to ensure compliance with product standards. Finally, compliant extracts are packaged using sealed materials to ensure quality and shelf life.

This outlines the general production process of licorice extract, where stringent control of operational conditions and parameters is necessary to meet quality and purity standards and comply with relevant production regulations.

Licorice Extract Source Plant Introduction, Distribution, and Growth Environment

The source plant for licorice extract is licorice (scientific name: Glycyrrhiza), a perennial herb belonging to the Fabaceae family, known for its medicinal and edible value.

Licorice is primarily distributed across Asia, Europe, and North America, mainly thriving in temperate and subtropical regions along riverbanks, grasslands, and slopes. Licorice prefers sunny, loose, well-drained soil environments, showing adaptability to various soil types with a pH of 5.5-8.5, but it does not thrive in highly saline-alkaline or waterlogged areas. The plants typically reach heights of about 30-120 cm, with a root system that extends several meters deep, allowing them to survive in arid conditions; their long growth period results in roots rich in medicinal components.

Licorice is a drought-resistant plant with strong adaptability and a long growing season, generally sprouting in spring and maturing in fall. During growth, it typically requires ample sunlight and adequate moisture, but it is sensitive to cold and frost damage.

As an important medicinal plant, its roots are rich in glycyrrhizin, glycyrrhizic acid, and licorice saponins, widely used in traditional Chinese medicine, pharmaceutical preparations, and as food additives. Its roots, rhizomes, and root bark all possess medicinal value, making it a significant ingredient in traditional medicine and a natural drug resource. Due to its rich active ingredients and widespread growth, licorice is valued globally, and it has been cultivated to meet commercial demands, especially in regions like China, Iran, and Turkey, where licorice farming is significant, becoming one of the major economic crops.

Licorice Extract Processing and Storage

The processing of licorice extract typically includes several steps: first, licorice is pre-processed, including washing and slicing, followed by soaking or extraction to obtain the licorice extract; then, through filtration, concentration, and refining processes, impurities and solvents are removed to enhance the purity of the extract; finally, the extract undergoes drying to produce a powdered final product. During storage, licorice extract should be kept in a cool, dry place, away from direct sunlight and high temperatures, avoiding moisture, and sealed to extend its shelf life.
