Raw material sourcing and identity verification → cleaning → extraction with water / ethanol → filtration and concentration → purification → spray drying → milling and sieving → laboratory testing → packaging and batch traceability.
Each batch is tested for active marker content, heavy metals, microbiological parameters and pesticide residues, and can be supplied with a batch-specific Certificate of Analysis. Production follows ISO / GMP-compliant quality systems, and third-party laboratory reports are available on request.
Because the extract contains volatile components, store it in a sealed container in a cool, dry place away from direct sunlight, heat and strong odours.
Marker specifications, extract ratio, particle size, packaging and labelling can be customized. OEM and private label services are available — please contact us for samples and quotation details.
