High-purity botanical extractions and customized fruit juice powders manufactured in compliance with international food and supplement parameters.
Pu Er Tea Extract is a concentrated, bio-enhanced botanical extract derived from the post-fermented leaves of the ancient large-leaf tea tree, Camellia sinensis var. assamica, native exclusively to the unique geological conditions of Yunnan Province, China. Unlike typical green or black teas, Pu Er tea undergoes an extended, microbially driven solid-state fermentation process (facilitated by clean strains such as Aspergillus niger, yeasts, and other beneficial bacteria). This slow biochemical transformation dramatically alters its phytochemistry profile. Catechins, epigallocatechin gallate (EGCG), and typical tea monomer polyphenols undergo deep enzymatic and non-enzymatic polymerization, converting into complex bioactive compounds known as theabrownins, thearubigins, and theaflavins, while stabilizing metabolic-supportive gallic acid and L-theanine.
For B2B formulators, food scientists, and global nutraceutical manufacturers, standardizing these active fractions represents the difference between a simple food ingredient and a highly functional dietary compound. Scientific studies reveal that theabrownins—the dominant dark pigment in fermented Pu Er tea—play a fundamental role in activating AMPK pathways, supporting healthy blood lipid levels, and modulation of the gut microbiota (particularly by adjusting the Bacteroidetes-to-Firmicutes ratio). Achieving high purity, consistent solubility, and exact standardization requires deep biochemical expertise, state-of-the-art industrial processing plants, and robust verification mechanisms.
Standardized to deliver up to 40% Theabrownins, 30% total Polyphenols, and optimized gallic acid profiles for direct metabolic efficacy.
Specially processed for cold-water instant solubility with zero sediment or cloudiness, perfect for clean-label RTD beverages.
Strictly monitored to meet demanding EU & US FDA regulations for heavy metals, solvent residue limits, and pesticide levels.
Established as a pioneer in the plant extraction industry, Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has served as a premier manufacturer and exporter of botanical active ingredients for more than 20 years. Combining multi-disciplinary research and development, industrial extraction facilities, and international trade capabilities, we supply high-specification ingredients to formulation laboratories worldwide.
TRB operates three distinct processing plants: one focused entirely on high-purity herbal extracts (including our advanced Pu Er Tea Extract lines), a dedicated bee products factory, and a specialized facility for animal-derived extracts. Our commitment to strict processing standards is demonstrated by our comprehensive suite of global quality certifications:
Through our commitment to clean processing, TRB was awarded the 2026 Global Biotechnology and Life Sciences Award — "Best Global Herbal Extract Provider 2026".

Why sourcing from a dedicated Chinese factory is essential to guarantee botanical authenticity, cost efficiency, and raw material traceability.
From raw agricultural harvesting to refined extraction, the Chinese supply chain provides unique structural advantages that cannot be replicated elsewhere:
Genuine Pu Er tea is legally protected as a geographical indication product. The large-leaf varietal Camellia sinensis var. assamica requires the specific red soils, high elevations, and warm, humid microclimates of Yunnan Province. Sourcing from a factory with direct Yunnan sourcing networks ensures authentic raw materials containing the targeted microbial fermentation precursors.
Our processing lines utilize low-temperature vacuum extraction, membrane concentration, and high-efficiency spray drying. This maintains the thermal stability of sensitive polymers like theabrownins and prevents oxidation. The resulting powder features rapid, residue-free dissolution in both hot and cold liquids.
With an annual extraction capacity reaching thousands of metric tons, Chinese manufacturers benefit from integrated supply logistics, stabilizing bulk raw material prices. Sourcing directly from our factory eliminates intermediaries, offering substantial cost savings for large-scale formulation orders.

How cross-border buyers and brand formulators are using Pu Er Tea Extract to address clean-label, functional food, and nootropic trends.
Consumer demand is shifting toward botanical extracts with clinical validation, clean labels, and versatile flavor profiles. Pu Er Tea Extract meets these needs across several industries:
Its natural astringency, rich amber hue, and rapid solubility make it an ideal base for ready-to-drink functional beverages. It blends well with functional sweeteners, citrus powders, and sparkling prebiotic waters.
Designed for capsules, tablets, and powdered meal replacements, Pu Er tea extracts support lipid metabolism and blood sugar regulation. Formulators regularly combine it with L-Carnitine, Green Coffee Bean Extract, and Konjac Glucomannan.
TRB specializes in anti-aging, brain health, and longevity research. Our Pu Er Tea Extract naturally contains synergistic L-Theanine and small quantities of caffeine, promoting alert focus without the energy crashes typical of synthetic stimulants.
Navigating global compliance is a primary challenge for ingredient sourcing. Different regions enforce strict limits on residues, making generic agricultural products unsuitable for distribution in international markets.
Our analytical laboratories perform validation testing on every raw material lot before processing:
Technical and logistical questions regarding the sourcing, chemical stability, and customization of bulk Pu Er Tea Extract.
A1: Green tea is unfermented and rich in monomeric catechins (primarily EGCG), while black tea is oxidized, yielding monomeric theaflavins. Pu Er tea undergoes microbial post-fermentation, polymerizing these simple catechins into complex, high-molecular-weight theabrownins. This unique molecular structure is responsible for Pu Er's distinct support for metabolic pathways and gut health.
A2: We source our raw tea leaves from partner cultivation sites in Yunnan that monitor pesticide applications. Each incoming batch is tested for over 500 pesticide residues, including Glyphosate and Fipronil. We only process raw materials that meet strict EU and US EPA pesticide residue limits.
A3: Yes. Our Pu Er Tea Extract is processed through microfiltration and membrane concentration steps to remove insoluble starches and structural fibers. The final powder is fully soluble in cold water (15°C) without creating cloudiness or sediment, and it maintains stability in acidic liquid systems (pH 3.0–5.5).
A4: Yes. We offer decaffeination services using food-grade solvents or supercritical CO2 extraction, reducing caffeine levels to under 1.0%. We can also adjust extraction parameters to optimize levels of target active ingredients, such as specific concentrations of theabrownins or polyphenols.
A5: Our standard export packaging is 25 kg fiber drums lined with dual-layer food-grade polyethylene bags. Our standard MOQ is 25 kg (one drum), though sample orders are available for verification testing. Under proper storage conditions (cool, dry environment, out of direct sunlight), the extract has a shelf life of 24 months.
A6: Our factories operate under quality management systems certified by GMP, ISO 9001, ISO 22000, and HACCP. We also maintain Halal, Kosher, and USDA Organic certifications, along with US FDA registrations to simplify global customs clearance.
