Our Production Process

Algalif’s unique, enclosed photobioreactor cultivation system and its proprietary three-phase cultivation process, help ensure optimal growth of the microalgae and high yield of pure astaxanthin from Haematococcus pluvialis.

Three-phase Cultivation 

  • In the Green Phase, the algae biomass is cultivated under optimal growth conditions using pure Icelandic water and high-quality nutrients to make the algal cells grow and multiply.
  • In the Starvation Phase, the algae culture is exposed to stress conditions to induce astaxanthin synthesis.
  • When a high amount of astaxanthin is accumulated, the Red Phase starts. The algae culture is harvested for downstream processing.
  • The algal biomass is then dehydrated, and the algal cells are cracked. Astaxanthin is recovered using solvent-free supercritical CO2 extraction, and standardized with high-oleic sunflower oil to produce a high-quality oleoresin.
