aged ginseng extract

Aged ginseng extract isn't a commodity item. Root age, processing region, and solvent ratio all shift the final profile. At Huacheng Biotech, the process starts with whole roots from Changbai Mountain growers who hold material for 5–6 years before digging. Delaying harvest means more labor overhead for the farmer, so negotiating volume early keeps pricing in the budget range. Once the roots arrive, our extraction line uses an ethanol‑water gradient optimized for Rg1 and Re solubility, then low‑temperature concentration to avoid caramelization. The resulting powder passes through 80 mesh and typically lands around 3–5% total ginsenosides by UV, with a Rb1/Rg1 ratio near 1.2–1.6 depending on lot. Buyers who need tighter ratios can request a custom blend from two validated lots. Each shipment includes a third‑party micro test and a private HPLC chromatogram; we store these by batch so you can compare lots. Huacheng holds FDA, HACCP, GMP, CE, and BRC certifications, and the whole chain—from farm extraction to final milling—stays under our audit. For supplement contract manufacturers and private label brands, that combination of technical traceability and bulk pricing turns aged ginseng from a niche ingredient into something you can scale.
