Green Tea Extract EGCG: The B2B Procurement Blueprint for Assay Accuracy, EFSA Compliance, and Global Supply Reliability

UV spectrophotometry measures total absorbance at specific wavelengths (typically 278 nm), detecting all phenolic hydroxyl structures indiscriminately. This captures unwanted tannins, degraded polyphenolic fractions, and gallic acid, routinely overestimating EGCG concentrations by 15% to 30%. In contrast, Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) physically separates individual catechins—including (-)-EGCG, (-)-ECG, (-)-EGC, and (-)-EC—through specialized stationary phases, quantifying each against an authentic analytical reference standard. For regulatory compliance and consistent formulation, always specify HPLC testing.

Following EFSA safety recommendations regarding daily intake thresholds for green tea catechins (recommending consumer supplements stay below 800 mg EGCG per day), brands require precise active compound percentages on raw material CoAs. SV Botanica manufactures precisely calibrated grades (from 50% to 98% EGCG) alongside low caffeine profiles (<0.5%). This provides product formulators with verified metrics to establish safe daily serving sizes while fulfilling all regulatory documentation needs in Europe and worldwide.

We adhere to green, non-toxic manufacturing processes. Our extraction columns use exclusively USP/EP-compliant hydro-ethanolic solutions (water and pharmaceutical-grade grain ethanol). We avoid toxic industrial solvents like methanol, hexane, acetone, or chlorinated hydrocarbons. Residual ethanol levels consistently fall well below 5,000 ppm, easily passing strict USP <467> and Ph. Eur. 5.4 Class 3 limits.

Ethylene Oxide (ETO) is strictly avoided across our facilities—we never apply ionizing radiation or gas-sterilization techniques. For EU-bound consignments, representative samples are evaluated at accredited third-party laboratories using LC-MS/MS and GC-MS/MS. Our screening covers 500+ active compounds under Regulation (EC) No 396/2005 alongside 2-chloroethanol testing (below <0.02 mg/kg), ensuring consignments clear border inspections smoothly.

Our standard Minimum Order Quantity (MOQ) for commercial production is 25 kg. Packaging consists of tamper-evident, food-grade double polyethylene inner bags placed within heavy-duty, moisture-barrier fiber drums containing food-safe desiccants. When kept unopened in cool, dark, and dry conditions below 25°C, our standardised EGCG powders maintain analytical stability for 36 months.

Yes. While our standard grade is calibrated to an 80-mesh powder (ideal for capsule filling and blending), we also manufacture customized 100 to 120-mesh micronized powders for direct tableting, as well as de-bittered, cold-water-soluble extracts engineered for crystal-clear RTD beverages and powdered drink stick-packs.
