china sweet tea extract

The Huacheng Biotech sweet tea extract is derived from the leaves of Rubus suavissimus, a perennial shrub native to Guizhou and Guangxi provinces. The key sweet component, rubusoside, is a diterpene glycoside with a sweetness intensity roughly 200 times that of sucrose. Our standard extract is offered at 80%–95% rubusoside purity, but we also supply lower concentrations for cost-sensitive projects. The powder is off-white to light yellow, fully water-soluble, and stable under typical food processing conditions—pasteurization, UHT, and acidic beverages up to pH 3. Because rubusoside has no fermentable carbohydrates, it fits clean-label and sugar-free positioning while delivering clean sweetness without the bitter or licorice notes sometimes found with stevia. Huacheng’s industry chain begins with long-term grower agreements covering over 500 hectares of certified farmland. Raw leaves are harvested between May and September, then dried and stored in climate-controlled warehouses before extraction. The extraction line uses only water and ethanol, followed by ion exchange resin purification, concentration, and spray drying. The facility operates under ISO 22000 food safety management and is audited annually for BRC, GMP, HACCP, and FDA compliance. This scale and integration let us offer China sweet tea extract at a budget-friendly price point while meeting the documentation demands of multinational buyers. Whether you need a single drum for prototyping or a full container load, the same batch-level quality applies. Every shipment comes with a certificate of analysis covering appearance, rubusoside assay (HPLC), loss on drying, ash, heavy metals (Pb, As, Cd, Hg), residual pesticides, and microbiological counts. We also provide stability data and formulation support if you are adapting an existing recipe to replace artificial sweeteners or high-intensity sweeteners that may not align with consumer preferences.
