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.
