  2. Extraction Process: The extraction usually employs a solvent extraction method. The shelled seeds are crushed or chopped and then placed in extraction equipment with a solvent (like ethanol or water) for soaking. During this process, the solvent dissolves the active components from the seeds.
  3. Concentration and Separation: After a specified soaking time, the extract is concentrated, increasing the concentration of active components in the solution. Following this, solid particles and impurities are removed through filtration or centrifugation to obtain a concentrated Torreya grandis extract.
  4. Drying and Milling: The resulting concentrated extract is dried, often using spray drying or vacuum evaporation, to eliminate the solvent and produce a solid Torreya grandis extract. The extract is then milled into a powdered form.
  5. Quality Inspection and Packaging: The Torreya grandis extract undergoes quality testing, including checks on appearance, component content, and microbial levels. Once it meets specifications, it is packaged, commonly in aluminum foil bags or plastic drums, to ensure quality and shelf life.
  6. Storage: The packaged Torreya grandis extract is stored in a dry, cool, and ventilated area, avoiding direct sunlight and humidity to maintain stability and quality.
