china sweet tea extract factory

Hunan Huacheng Biotech runs a sweet tea extract factory structured around a full industry chain, from leaf sourcing to final extract. The facility sits in Hunan province, where Rubus suavissimus grows locally, shortening transport time and preserving leaf freshness. Raw material is handled through solvent extraction and membrane filtration, followed by spray drying into a fine powder. Standard specs range from 10% to 80% rubusoside, tested by HPLC. Because the plant houses its own testing lab, every lot is checked for heavy metals, pesticides, and microbial limits before release. Certification stack includes FDA registration, HACCP, GMP, CE, and BRC, which means audits cover production flow, cleaning validation, and paperwork consistency. Capacity sits in the hundreds of metric tons per year, so lead times stay predictable even for container-sized orders. The factory also runs a parallel monk fruit extract line, sharing purification infrastructure, which helps keep overhead low across products. For developers working on zero-calorie beverages, sugar-free confectionery, or herbal blends, the extract blends smoothly without bitter aftertaste. Custom sieving from 60 to 120 mesh is available to match mixing behavior in dry blends. Packaging defaults to 25 kg fiber drums with double PE liners, and inner vacuum packing adds shelf-life buffer during ocean freight. Documentation support includes a full CofA, MSDS, and a non-GMO statement. If your project needs rubberusoside ratios verified by a third party, we coordinate with Eurofins or SGS at your expense. All records are archived for five years, which simplifies annual vendor audits on your side. Pricing tiers follow volume brackets, and we provide a landed cost estimate inclusive of freight and duties for your port once you share annual forecast numbers.
