ODM Purple Cabbage Extract PowderThe global market for catechins, specifically Epigallocatechin Gallate (EGCG), has transitioned from simple beverage additives to high-precision pharmaceutical intermediates. As chronic metabolic conditions rise globally, the demand for high-purity, standardized catechin OEM manufacturing has reached an industrial inflection point.
Unlike generic extract suppliers, our factories focus on Molecular Integrity Preservation. We don't just extract; we refine using chromatography-grade processes to ensure that bio-activity levels exceed standard industry benchmarks by up to 15%.
We provide cross-industry solutions ranging from water-soluble catechin monomers for functional beverages to micro-encapsulated powders for dietary supplements, ensuring maximum bioavailability and shelf-life stability.
Benefiting from the solid foundation provided by its parent company, Xi'an Tianben Bioengineering Co., Ltd., Botanical Cube Inc. focuses on researching, developing, producing and selling healthy natural ingredients. With more than two decades of industry experience, it has become a leader in the field, specializing in providing high-quality plant extracts and customized solutions to global customers. Services meet the needs of industries including herbal medicine, health foods, dietary supplements, food and beverages, daily chemicals and cosmetics.
Our operations are supported by three companies - Xi'an Tianben Bioengineering Co., Ltd., Botanical Cube Inc. and Shaanxi Tianben Kangyuan Biotechnology Co., Ltd. - which together operate 3 production bases covering more than 100 acres and process more than 3,000 tons of plant raw materials each year. The product range includes more than 200 plant extracts.
As a leading OEM manufacturer, we are moving beyond traditional extraction. Our 2025-2030 roadmap focuses on the synergy of phytochemistry and biotechnology.
Utilizing subcritical water extraction (SWE) to eliminate residual solvents (Ethanol/Methanol), ensuring 100% "Clean Label" compliance for EU and North American markets.
Developing liposomal catechin powders that improve intestinal absorption by 400%, overcoming the traditional low bioavailability of polyphenol molecules.
Patented spray-drying techniques that prevent catechin oxidation at room temperature, extending the shelf-life of finished OEM products to 36 months.
Real-time HPLC monitoring during the manufacturing cycle to ensure batch-to-batch consistency of Epicatechin (EC) and Epicatechin Gallate (ECG) ratios.
Our first factory was established in 2012 in Sanyuan City, Xi'an, four years after our company was founded. At that time, our production experience was still in its early stages, and we faced many challenges as we worked to refine our processes. However, we remained committed to continuous improvement, investing heavily in technology, training, and quality control to strengthen our capabilities.
Powder collection, crushing and sieving, mixing and drying processes are all performed in a Class 100,000 cleanroom environment. Our operators strictly follow hygiene protocols and wear sterile gowns, masks and gloves to maintain product purity and safety.
Full support for EU Novel Food dossiers. We ensure catechin levels comply with the latest EFSA safety limits regarding daily intake of green tea extracts, preventing regulatory bottlenecks for our European partners.
Our wholesale manufacturing processes adhere to cGMP (Current Good Manufacturing Practices). We provide detailed COA (Certificate of Analysis) with HPLC, GC-MS, and ICP-MS testing for heavy metals and pesticides.
Localized support for Japanese and Korean markets, where high-purity monomeric catechins are preferred for "Foods with Function Claims" (FFC) and specific health use labels.
Cold-water-soluble (CWS) catechin powders with zero turbidity and neutral taste profile, ideal for RTD (Ready-to-Drink) tea and wellness shots.
Topical-grade catechins with standardized EGCG content for anti-aging and UV-protection formulations in high-end skincare serums.
Pharma-grade purity (>98%) for use in metabolic syndrome research and medical-grade nutritional supplements.
Natural antioxidant application using catechin’s ability to prevent lipid oxidation in meat and bakery products, replacing synthetic BHT/BHA.
