Best Fisetin Strawberries Factories & Exporters

Chemically, the active compound fisetin (CAS 528-48-3) is identical regardless of source plant. However, strawberries naturally hold only ~160 µg/g fisetin, making a direct 98% strawberry extract commercially prohibitive (requiring tons of fresh fruit per kilogram of active). Most industrial suppliers utilize Cotinus coggygria or bio-fermented precursors to achieve affordable 98% purity, while using genuine strawberry juice powders or standard strawberry extracts (0.5%–5%) for holistic label claims. We supply both pure active material and authentic strawberry fruit matrices.

Our manufacturing partners hold validated certifications including cGMP, EU-GMP, CEP, ISO 9001, ISO 22000, and HACCP. Certification documentation, audit reports, allergen statements, Non-GMO verifications, and BSE/TSE declarations are provided during vendor qualification.

Each batch is subjected to high-resolution HPLC or UHPLC alongside UV-Vis spectra comparison and Thin Layer Chromatography (TLC). We routinely test for common flavonoid adulterants (e.g., synthetically boosted quercetin or luteolin analogs). Independent third-party verification through Eurofins, NSF, or SGS is readily coordinated on a lot-by-lot basis.

Standard packaging comprises 25 kg cardboard export drums with dual food-grade polyethylene interior bags. When stored in sealed containers protected from light, moisture, and high heat, the typical shelf-life stability is 24 to 36 months from manufacture date.

Yes. We offer micronization down to 80 mesh, 100 mesh, or 200 mesh (< 75 µm), alongside granulation processing for direct compression (DC grade) tablets to ensure smooth hopper flow and uniform capsule filling.
