Production Process of Black Walnut Extract

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

  1. Raw Material Collection and Preparation: Fresh black walnut fruits and bark are collected as extraction materials. The fruits should be mature but not rotten, and the bark should be healthy. Collected materials must be cleaned and pre-processed to remove impurities.
  2. Extraction Process: The cleaned black walnut fruits and bark are crushed or chopped and then placed into extraction equipment. Water or organic solvent extraction methods are usually employed, using boiling or soaking to extract the target components, such as tannins and flavonoids.
  3. Filtration and Concentration: The extraction liquid needs to be filtered to remove residues and solid particles. Then, through the concentration process, moisture is evaporated from the extraction liquid, resulting in a dense liquid or solid extract.
  4. Drying and Grinding: The concentrated extract may be semi-solid or solid and requires drying to reduce moisture content, enhancing stability and shelf life. After drying, the extract is ground into a powder or granular form for subsequent packaging and use.
  5. Packaging and Storage: Finally, the black walnut extract is packaged in appropriate specifications, such as bags or bottles. During packaging, measures should be taken to prevent moisture, light, and oxidation to maintain the extract's stability and quality. After packaging, the extract should be stored in a dry, cool, and light-protected environment to prolong its shelf life.

The entire production process requires strict control over operational conditions to ensure the extract's quality and safety, complying with relevant production standards and regulations to ensure the product's compliance and reliability.
