  • Alcohol-Water Extraction — Optimized ratio for high yield of Oleuropein while preserving heat-sensitive actives.
  • Low-Temperature Processing — Protects hydroxytyrosol and other antioxidant phenolics from thermal degradation.

2. Purification & Standardization

  • Filtration & Concentration — Removes insoluble fibers and chlorophyll impurities.
  • HPLC Standardization — Oleuropein content precisely adjusted to 20% or 40% by HPLC.
  • Heavy Metal & Pesticide Control — Every lot tested to meet USP, FCC and EU standards.

3. Drying Technologies

  • Spray Drying — Produces a fine, free-flowing powder with uniform particle size and excellent solubility.
  • Vacuum Drying Option — Available for heat-sensitive custom grades on request.
  • Stable Packaging — Sealed aluminum bags to protect against moisture, light and oxidation.
