Lemon Verbena Extract Production Process

The production process of Lemon Verbena Extract typically involves the following steps:

  1. Raw Material Collection and Preparation: Fresh Lemon Verbena leaves are collected as raw materials. The picked leaves should be fresh, free from pests and diseases, and harvested at the right time to ensure quality and composition. After harvesting, the leaves must be cleaned and dried evenly.
  2. Extraction Process: The dried Lemon Verbena leaves are crushed into a powdered form. Suitable extracting solvents (such as ethanol or water) are then used to extract the target components to form an extractive solution. The extraction can employ methods like room temperature infusion or heat reflux extraction to fully extract the desired compounds.

Separation techniques (like extraction or thin-layer chromatography) are then used on the concentrated liquid to obtain the purity of the target components.
  4. Filtration and Purification: The separated liquid undergoes filtration to remove impurities and solid particles, enhancing product purity. Additional purification methods (like crystallization or freeze separation) may also be employed to further increase the product's purity.
  5. Drying and Grinding: The purified extract is dried to remove residual moisture, resulting in a dry extract. Then, the dry extract is ground or granulated for easy packaging and application.
  6. Quality Inspection and Packaging: The extract undergoes quality inspection, assessing its composition and microbial standards to ensure it meets relevant criteria. Finally, extracts that meet quality standards are packaged using appropriate materials to ensure product stability and safety.
