Production Process of Cassava Leaf Extract

The production process of Cassava Leaf Extract typically includes the following main steps:

  1. Harvesting and Cleaning: Fresh cassava leaves are harvested and thoroughly cleaned to remove surface impurities, dirt, and pesticide residues.
  2. Chopping and Processing: The cleaned cassava leaves are chopped into appropriate-sized pieces and then treated by soaking in hot water or steaming to break down cell structures and release the active components.
  3. Solvent Extraction: The processed cassava leaf pieces are placed in a solvent for extraction, with common solvents including water, ethanol, or acetone. During extraction, the solvent dissolves nutrients and active substances from the leaves.
  4. Filtration and Concentration: The extract is filtered to remove solid residues and then concentrated through evaporation or reduced pressure, allowing the solvent to be recovered and the extract to reach the desired concentration.
  5. Purification and Drying: The concentrated cassava leaf extract undergoes purification to remove impurities and increase product purity. Finally, spray drying or vacuum drying methods are employed to convert the extract into a powder form, making it easier to store and transport.
  6. Packaging and Storage: The Cassava Leaf Extract is then packaged and stored under appropriate conditions, avoiding direct sunlight, high temperatures, and humidity to maintain its stability and active components.

Through these production steps, high-quality Cassava Leaf Extract is obtained for use in pharmaceuticals, food, and cosmetics.
