Extraction Technology: Solvent-Free Triple-Stage Filtration
💬 Technical Insight
"For dietary supplement manufacturers, batch-to-batch consistency in antioxidant potency is often more critical than peak purity numbers. Our three-stage membrane microfiltration and resin adsorption process is calibrated to maintain a stable catechin-to-total-polyphenol ratio across production batches, which directly supports consistent finished product potency claims."
— Blue Eye Bio R&D Team
The solvent-free aqueous extraction process avoids the residual ethanol or ethyl acetate concerns associated with conventional methods, making this grade particularly suitable for supplement brands marketing toward clean-label and solvent-free positioning claims.
Formulation Guidance: Encapsulation & Tablet Compression
Tea polyphenols present specific technical considerations when formulated into solid dosage forms:
- Hygroscopicity Management: As a naturally hygroscopic powder, storage in low-humidity environments (RH <60%) during processing is recommended to prevent caking and flowability issues during encapsulation.
- Flowability Enhancement: Co-processing with silicon dioxide (0.5%-1.0%) as a flow aid is commonly used to improve powder flow characteristics for automated capsule filling lines.
- Tablet Compression: For direct compression tablet formats, particle size uniformity (100% through 80 mesh) supports consistent tablet hardness and reduces capping/lamination defects.
- Bitterness Masking: For chewable or effervescent formats, co-formulation with natural sweeteners or flavor-masking agents is recommended to offset the inherent astringency of high-concentration catechins.
Regulatory & Quality Compliance
📋 Compliance Statement: Pesticide residue levels are tested and verified to comply with EU EC 396/2005 Maximum Residue Level (MRL) requirements. Heavy metal content (total <10ppm, lead <1ppm) is verified via ICP-MS testing in accordance with international pharmacopoeia standards. Every production batch is accompanied by an HPLC purity chromatogram and a Certificate of Analysis (COA).
Blue Eye Bio operates under a cGMP-certified manufacturing system, with product lines further certified to ISO, Kosher, and Halal standards, enabling seamless compliance across North American, European, and Middle Eastern export markets.
