Raw material procurement and screening
Plant-based ingredients are sourced from certified organic farms and collection sites.
A multi-level screening process is implemented, including checking the growing conditions of the plants, harvest time and freshness of the ingredients.
Use physical and visual inspection methods to exclude non-target material such as stumps, weeds or damaged plant parts.
Cleaning and Preparing
Use filtered and sterilized water for cleaning to ensure that the surface of the raw materials is free of dust, soil and other contaminants.
Dry the raw materials using natural air drying or gentle heating until the surface moisture is completely evaporated.
Ensure that the raw materials are not exposed to direct sunlight during the drying process to maintain their natural composition.
Crush
Select appropriate crushing equipment based on the type of raw materials and required particle size.
Use a single-sample, single-machine strategy to avoid cross-contamination.
After crushing, the machine is thoroughly cleaned to ensure purity for the next batch.
Extract
Select the appropriate extraction method according to the polarity of the target component, such as water extraction, alcohol extraction, or subcritical or supercritical extraction.
Control extraction conditions (such as temperature, time, solid-liquid ratio) to maximize extraction efficiency.
During the extraction process, samples are taken regularly and preliminary analyzes are performed to ensure the extraction effect.
Separation and Filtration
Use a filter membrane of at least 200 mesh for preliminary filtration to remove large particulate matter.
Suspended particles are further removed through efficient separation technologies such as centrifugation or membrane filtration.
Ensure the continuity and efficiency of the filtration process and avoid prolonged exposure of the extraction liquid.
Purification and enrichment
Use a macroporous adsorption resin for purification and select a resin suitable for the target compound.
Optimize elution conditions (such as eluent type, concentration, pH value) to improve purification efficiency.
During the recrystallization process, the material-to-liquid ratio, temperature and solvent are controlled to obtain high-purity extracts.
Condensed
A negative pressure evaporation system is used to control the temperature below 80°C to protect heat-sensitive ingredients.
Monitor relative density and solution concentration to ensure product consistency.
Samples are taken and analyzed regularly during the concentration process to assess retention of active ingredients.
Dry
Use appropriate drying techniques (such as spray drying or freeze drying) depending on the properties of the extract.
Control the drying temperature and humidity to ensure the quality and stability of the extract.
The dried product should have consistent moisture content and physical properties.
Quality inspection
Extracts are subjected to comprehensive chemical and microbiological testing, including HPLC, GC and mass spectrometry analysis.
Detect heavy metals, residual solvents and other possible contaminants.
Ensure each batch of products meets international quality standards and regulations.
Packaging
Use packaging materials that meet food grade or pharmaceutical grade standards.
Packed in a dust-free, controlled environment to prevent contamination.
Packaging design should ensure product stability and shelf life during transportation and storage.
Store
Store products in a controlled temperature and humidity environment to extend shelf life.
Track batches and expiration dates with an advanced inventory management system.
Regularly check storage conditions to ensure product purity and quality.
