Gardenia Blue

  • Active Ingredient: Genipin-peptide polymer.
  • Color Value : Ranges from E8 to E150 depending on concentration.
  • Appearance: Dark blue to navy fine powder or viscous liquid.
  • Solubility100% water-soluble; also soluble in ethanol and propylene glycol but insoluble in most organic solvents.
  • Stability:
    • pH Stability: Stable between pH 4.0 and 8.0. Unlike many natural blues, it maintains a consistent hue without shifting to purple in acidic environments.
    • Thermal Stability: Highly resistant to heat, maintaining color up to 80°C to 100°C, making it suitable for baking and UHT processing.
    • Light Sensitivity: Sensitive to intense light; formulations should prioritize opaque packaging for long-term shelf life.

Functions & Market Benefits

  • Synthetic Blue Replacement: Serves as a direct, clean-label alternative to synthetic dyes like Brilliant Blue FCF (Blue No. 1).
  • Low Sensory Impact: Advanced extraction results in a pigment that is largely tasteless and odorless, ensuring it does not interfere with the flavor of food or beverages.
  • Health Benefits: Beyond its color, the extract contains iridoid glycosides like geniposide, which have been studied for antioxidant, anti-inflammatory, and liver-supportive properties.
  • Superior to Spirulina: Offers significantly better heat and acid stability than Spirulina-derived phycocyanin, expanding its use in carbonated drinks and gummies.
