sweet tea leaf extract

Sweet tea leaf extract's main sweet component is rubusoside, a steviol glycoside analogue with a clean sweetness profile and slight delay but no lingering bitterness when used correctly. As a technical supplier, Huacheng Biotech usually provides it as a pale white to off-white powder, water-soluble at room temperature up to around 20% w/v, and heat-stable at typical pasteurization temperatures. Typical specification: rubusoside content by HPLC ≥90%, loss on drying ≤5%, ash ≤0.5%, and standard heavy-metal limits compliant with FDA and EU regulations. Our extraction process uses water and ethanol only—no harsh solvents—which keeps the extract eligible for clean-label applications. We manage the entire chain, from sourcing the dried leaves in Hunan mountain areas to final spray-dried powder in our ISO-certified facility. This vertical integration is why we can offer prices that often beat brokers without sacrificing consistency. Certifications on file include FDA registration, HACCP, GMP, and BRC, so the paperwork for your quality audit is already in order. Applications span dairy alternatives, flavored waters, mouthwash, and bakery where partial sugar reduction is the goal. Because rubusoside can enhance fruit flavors, it's also used in fruit preparations and syrups. If you need organic or specific particle sizes, we can accommodate with MOQs that are usually lower than market average, since we run small-scale pilot batches regularly. For product developers, we can share sensory data and recommended usage levels—typically starting at 0.01–0.05% in final product, adjusted for synergy with other bulk sweeteners like erythritol.
