Production Process of Sage Extract

The production process of sage extract typically involves the following main steps:

  1. Raw Material Preparation: Fresh sage plants are collected, usually using the whole herb or leaves as the primary material, cleaned, and treated to remove soil, impurities, and stems.
  2. Rough Extraction: The cleaned sage material is crushed or ground and then soaked in an appropriate solvent (such as ethanol, water, or acetone) for rough extraction, allowing the active components to dissolve in the solvent.
  3. Solvent Evaporation and Concentration: The rough extract undergoes solvent evaporation and concentration to remove excess solvent and moisture, resulting in concentrated sage extract.
  4. Separation and Purification: The concentrated extract is separated and purified using typical methods like filtration, cooling crystallization, and thin-layer chromatography to enhance product purity and activity.
  5. Drying and Pulverizing: The purified sage extract is dried using methods such as spray drying or vacuum drying, creating a powder form for easy packaging and use.
  6. Quality Testing: The final sage extract undergoes quality testing, including active ingredient content, microbial testing, and heavy metal testing, ensuring compliance with relevant standards and regulations.
  7. Packaging and Storage: Finally, the sage extract meeting quality standards is packaged in sealed aluminum bags or plastic containers and stored in a cool, dry place, avoiding direct sunlight to maintain product stability and effectiveness of the active ingredients.

The entire production process requires strict control of operations and parameters to ensure the quality and safety of the final product. Simultaneously, the production must comply with relevant regulations and standards to meet market demands.
