china purified stevia leaf extract

Huacheng Biotech manages steviol glycosides from seedlings to finished product. Partner farms in Hunan and Jiangxi follow standardized harvest and drying windows, supplying stable, high-glycoside leaves. In the factory, multi-stage counter-current extraction, ceramic membrane filtration, and ion-exchange resin produce a purified extract. It can then be standardized to more than 90% total glycosides or to a single Reb A level from 60% to 98%. Every batch is tested for microbiology, heavy metals, pesticides, and solvent residues, with the report supplied in the shipment. FDA registration, HACCP, GMP, CE, and BRC are maintained through annual audits and site inspections. The documentation supports formulas exported to the EU, North America, and Southeast Asia without creating a second compliance burden. Vertical integration also keeps kilogram- and ton-scale pricing competitive. Vacuum foil bags and fiberboard drums are available, and orders can normally be confirmed within 48 hours.
