English English As an established global OEM/ODM green tea extract supplier and manufacturer, BKYULA Biotech integrates advanced hydro-ethanolic extraction with resin adsorption purification. We guarantee rigorous phytochemical profiling by validated High-Performance Liquid Chromatography (HPLC) to meet stringent global pharmacopeia standards (USP, EP, FCC).
| Standardized Grade | Total Polyphenols | Epigallocatechin Gallate (EGCG) | Caffeine Profile | Primary Industrial Application |
|---|---|---|---|---|
| HPLC Grade Ultra-Pure EGCG | ≥ 98.0% (UV) | ≥ 94.0% – 98.0% (HPLC) | Decaffeinated (≤ 0.5%) | Nutraceutical Capsules, Oncology Research, Anti-Glycation Skincare |
| Standard Beverage Clarified | ≥ 50.0% – 70.0% | ≥ 30.0% – 40.0% | Natural (4.0% – 7.0%) | RTD Functional Teas, Clear Energy Beverages, Isotonic Drinks |
| Decaffeinated Polyphenol 90 | ≥ 90.0% (UV) | ≥ 45.0% – 50.0% | Decaffeinated (≤ 0.5% – 1.0%) | Weight Management Blends, Nighttime Metabolic Health Tablets |
| Fermented Natural L-Theanine | N/A (Amino Complex) | N/A | Zero (≤ 0.1%) | Nootropic Formulations, Stress Resilience Powders, Sleep Hydration |
| High Catechins Antioxidant | ≥ 80.0% (UV) | ≥ 50.0% Total Catechins | Controlled (≤ 3.0%) | Clean-Label Food Preservatives, Dietary Antioxidant Synergies |
Global regulatory bodies and health-conscious consumers demand water-based and supercritical CO₂ decaffeination techniques over chlorinated chemical solvents (like ethyl acetate or methylene chloride). Modern B2B buyers prioritize pesticide-free green tea extracts with residual solvent limits compliant with EU and FDA pharmacopeial thresholds (≤ 0.1% caffeine without active catechin degradation).
Native EGCG suffers from rapid gastrointestinal degradation and poor enterocyte permeation. Forward-looking brands increasingly procure micro-encapsulated green tea extracts and phospholipid-complexed polyphenols (Green Tea Phytosomes). These novel dispersion technologies achieve up to 3x higher systemic bioavailability for metabolic and cardiovascular end products.
Traditional green tea extract suffers from astringent bitterness and sediment clouding upon chilling. Advanced OEM/ODM clients require debittered, high-clarity polyphenols engineered specifically for ready-to-drink (RTD) cans, functional sparkling waters, and effervescent tablet sticks that dissolve crystal clear at 4°C without sedimentation.
Our production facilities in Xi'an, Shaanxi, are fully audited and verified onsite by the SGS Group. Operating under cGMP, ISO 9001:2015, ISO 22000, and HACCP standards, every batch conforms to verified clean-room protocols, ensuring zero cross-contamination and global food-grade safety.
We operate independent in-house chromatography laboratories equipped with dual HPLC systems, UV-Vis spectrophotometers, and gas chromatographs. Every export lot comes accompanied by a comprehensive Certificate of Analysis (COA) specifying botanical origin, active compounds, heavy metals (<10ppm), residual solvents, and pesticide scans.
Beyond bulk raw powders, BKYULA Biotech engineers finished dosage solutions: custom mesh sizing (80 to 200 mesh), customized agglomerated instant granules, multi-ingredient synergistic blends (e.g., Green Tea + Ashwagandha + ACV), softgels, two-piece hard capsules, and automated private-label pouching.
For standardized catalog powders (such as EGCG 50%, Polyphenols 98%), our standard minimum order quantity starts from 1 kg for trial formulation testing. Bulk commercial runs begin at 25 kg fiber drums. For custom contract tableting, capsule encapsulation, or custom mesh milling, the MOQ is 50 kg to 100 kg depending on formula complexity.
We mandate High-Performance Liquid Chromatography (HPLC) coupled with Diode Array Detection (DAD) based on the USP monograph protocol for precise quantitation of individual catechins (-EGCG, -ECG, -EGC, -EC). Total polyphenols are cross-verified via UV-Vis spectrophotometry using gallic acid equivalents (GAE).
Our extraction lines utilize green hydro-ethanolic solutions without aromatic hydrocarbons. We monitor batches via GC-MS for residual solvents in accordance with USP <467> and EP limits. Total PAH4 (benzo[a]pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene) are strictly maintained under 10 ppb to comply with current EU Food Safety Commission regulations.
BKYULA Biotech exports directly under EXW, FOB, CFR, CIF, CIP, and full door-to-door DDP terms across North America, the EU, South America, and Southeast Asia. Every export shipment includes an authentic commercial invoice, packing list, batch COA, Certificate of Origin, Non-GMO declaration, BSE/TSE-free certification, and allergen statement.
