In modern industrial applications, chemical antioxidants like BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are facing intense consumer and regulatory pushback. Green Tea Polyphenols, with their potent radical-scavenging properties, offer a direct, clean-label substitution. The primary active component, Epigallocatechin Gallate (EGCG), represents a multi-functional therapeutic profile acting as a cellular protective shield, lipid stabilizer, and natural preservative. However, industrial formulation requires deep understanding of pH stability, temperature parameters, and structural discoloration. UniCare's technical support works closely with clients to bypass these physical hurdles, delivering stabilized, non-hygroscopic, and decaffeinated formulations optimized for specific end-use matrices.
Rooted in science, committed to sustainable innovation and long-term partnership.
Intelligent engineering designed to handle large-scale demand with micro-level quality control.
UniCare operates the most advanced extraction facility in China.

Our systems guarantee repeatable parameters, minimizing batch-to-batch variations in moisture, density, and active content.
Our structural production highlights include dynamic countercurrent extraction loops, a specialized acetone-solvent pathway compliant with EU GMP standards, and six dedicated 20-ton industrial fermentation vessels optimized for enzymatic biotransformation processes.
Our infrastructure operates under rigorous sanitary and quality guidelines enforced by national pharmaceutical GMP.
Our Ginkgo Biloba and Green Tea platforms conform to strict European monographs, simplifying regulatory clearance.
Real-time telemetry tracks and records temperature, solvent density, and flow rates to ensure product uniformity.
Equipped with industry-leading physical partition columns and industrial spray dryers to protect thermo-sensitive actives.
High-volume processing capacity ensures continuous, stable supplies for global supplement and food brands.
Featuring annular dynamic countercurrent (10T & 15T) and multi-functional lines to maximize bioactive yields.
Analytical precision, physical security, and absolute biological traceability.
Our dedicated central laboratory functions under ISO 17025 (CNAS) parameters. We address critical safety concerns within the botanical industry, specifically targeting organic solvent residues, heavy metals, Polycyclic Aromatic Hydrocarbons (PAHs), and pesticide residues (in alignment with EC 396/2005 regulations). Our lab houses top-tier chromatography and spectrometry setups to deliver verified Certificate of Analysis (CoA) reports for every lot.

Innovating at the intersection of molecular biology and sustainable agriculture.
By reinvesting 10% of net profits back into research, UniCare explores enzymatic biotransformations. In partnership with the Beijing University of Chemical Technology, we scale up novel biotechnologies that enhance bioavailability and remove unwanted components like caffeine without degrading the target antioxidant polyphenols.
Our joint projects focus on biocatalysis pathways to produce high-value derivatives for premium cosmetic and dietary supplement applications.
Quality begins in the soil. UniCare maintains dedicated cultivation bases for Ginkgo Leaf, Epimedium, Olive Leaf, and Green Tea. Each crop cycle conforms to Good Agricultural and Collection Practices (GACP).
Our crop management systems map pesticide and soil conditions, allowing us to trace each extraction lot back to the specific harvest zone. This rigorous approach keeps contaminants and pesticide residues exceptionally low.
Exploring the next frontier of phytochemistry: Bio-availability, Eco-friendly Solvents, and Target Formulations.
Standard green tea polyphenols exhibit relatively low intestinal absorption due to rapid metabolism and poor membrane permeability. UniCare’s current research focuses on micro-encapsulation, liposomal carriers, and self-emulsifying drug delivery systems (SEDDS) to shield the molecules and significantly improve their absorption profiles in dietary supplement formats.
We are transitioning our manufacturing lines toward subcritical water extraction and carbon dioxide (CO2) supercritical fluid processing. These technologies eliminate organic solvents entirely, resulting in high-purity, environmentally friendly extracts that align with global ESG expectations.
Across regional markets, application demands vary. In North America, the focus is on sports nutrition, demanding high-purity, decaffeinated EGCG powder with excellent water solubility. In the European Union, compliance with tight pesticide regulations is paramount. In Asia-Pacific, green tea polyphenols are widely used in anti-aging cosmetic formulations, requiring high-stability, decolorized forms to prevent product browning. UniCare offers tailor-made versions of our extracts to address these specific regional and industry requirements.
Industrial insights and technical clarification from our technical team.
Green tea polyphenols consist mainly of catechins: Epigallocatechin Gallate (EGCG), Epigallocatechin (EGC), Epicatechin Gallate (ECG), and Epicatechin (EC). EGCG is the most abundant and studied component, responsible for the majority of the extract’s antioxidant and metabolic support properties.
We use selective adsorption resins and partition solvent technology to reduce caffeine levels to below 1.0%, and even below 0.5% for specialized applications, without damaging the delicate molecular structures of the primary catechins.
Yes, all raw materials are harvested from our GACP-monitored planting bases. Each batch is analyzed using GC-MS/MS systems to confirm full compliance with European Regulation (EC) No 396/2005 guidelines before export.
Our partner factories hold complete international quality management system certifications, including EU GMP, China GMP, CEP (Certificate of Suitability to the monographs of the European Pharmacopoeia), ISO 9001, ISO 22000, and HACCP.
We pack our high-purity polyphenols in vacuum-sealed, double-layer food-grade polyethylene bags inside heavy-duty fiber drums. In addition, we can introduce protective nitrogen flushing and dry-barrier agents for highly hygroscopic grades.
Yes, our production lines can be set to produce specific ratios of EGCG (from 40% up to 98% purity), as well as customized levels of total tea polyphenols, catechins, or customized particle size ranges to match your formula requirements.
