Walnut Shell Extract Production Process

The production process of walnut shell extract typically includes the following steps:

  1. Collection and Cleaning: Fresh walnut shells are collected and cleaned to remove surface impurities, ensuring the raw material is clean and hygienic.
  2. Grinding and Crushing: The clean walnut shells are ground and crushed to increase extraction efficiency. Mechanical grinding or crushing methods are often employed to produce powder or granules.
  3. Solvent Extraction: The ground walnut shell samples are mixed with an appropriate solvent (such as ethanol or water) for extraction. Under suitable temperature and time conditions, effective components within the walnut shells dissolve into the solvent.
  4. Filtration and Concentration: After extraction, the extract is filtered to remove residues and impurities. Techniques like evaporation or vacuum concentration are used to remove the solvent, yielding a concentrated walnut shell extract.
  5. Drying and Grinding: The concentrated extract is dried to eliminate any residual moisture to reach the desired water content. Then, it is ground into a fine powder.
  6. Testing and Packaging: The final product undergoes quality testing to ensure it meets relevant standards and regulations. It is then packaged, typically in plastic bags, aluminum foil bags, or sealed containers, to ensure product quality and stability.
  7. Storage and Transportation: Finally, the packaged walnut shell extract is stored in a dry, cool, and ventilated area, avoiding direct sunlight and humid conditions to prolong its shelf life. Care is taken during transportation to prevent vibration and collision, ensuring product integrity and stability.

Walnut Shell Extract Source Plant Introduction, Distribution, and Growing Environment

The source plant of walnut shell extract is the walnut tree, scientifically known as Juglans regia. This tree belongs to the Juglandaceae family and is a common, large deciduous tree mainly distributed in temperate regions of Asia, Europe, and North America. Below is a detailed description of the walnut tree, including its introduction, distribution, and growing environment:

  1. Plant Introduction:
  • The walnut tree is a large tree, reaching heights of over 25 meters, with a stout trunk and gray-brown bark, exhibiting a distinct texture. Its leaves are compound, composed of 5-9 leaflets arranged pinnately, elongated and narrow with serrated edges.
  • The flowers of the walnut tree are unisexual, with male and female flowers growing separately on the same tree, typically blooming in spring. The fruit is a drupe with a leathery outer shell containing the walnut kernel that we commonly see.
  1. Distribution:
  • The walnut tree is native to Central Asia, predominantly found in regions such as Iran, Turkey, and Greece and has gradually been introduced to Europe, North America, and elsewhere.
  • In China, walnut trees are primarily found in the Yangtze River basin, Yellow River basin, Liao River basin, especially in areas like Shaanxi, Gansu, and Shanxi, which are known for high walnut production.
  1. Growing Environment:
  • The walnut tree thrives in warm and humid climates, with an optimal temperature range of 15°C to 25°C and an annual rainfall of over 600 millimeters. While it is not strict regarding soil requirements, it prefers deep, fertile, well-drained sandy loam.
  • The walnut tree requires ample sunlight, as sufficient sunlight promotes fruit development and ripening.

In summary, the walnut tree is the primary source of walnut shell extract, mainly distributed in temperate regions of Asia, Europe, and North America, with a preference for warm, humid, and well-lit environments. In such conditions, walnut trees flourish and produce nutrient-rich nuts with medicinal value for consumption and extraction of beneficial components.

Walnut Shell Extract Processing and Storage

The processing of walnut shell extract includes several key steps: First is material handling, which involves cleaning and drying the collected walnut shells; next, the extraction process uses appropriate solvents (such as ethanol or water) for leaching and extraction; then, concentration and filtration processes refine the extract; finally, drying and grinding yield the finished walnut shell extract.

For storage, walnut shell extract should be kept in a cool, dry, and ventilated environment, away from direct sunlight and high temperatures, to prevent moisture ingress, mold, or spoilage. It should be stored in sealed containers to avoid contact with air and humidity. Regularly check the product's appearance and smell to ensure quality and safety.
