The microalgae biomass for the production of astaxanthin can be produced in various systems. We use closed glass systems for production at our location. These tubes have already proven themselves in other productions and offer various advantages. Compared to open systems (e.g. open ponds), they are less susceptible to contamination. In addition, individual parameters such as pH value, CO2 and O2 content can be better adjusted. Thanks to their optimized, transparent design, higher growth rates and increased astaxanthin levels can be achieved.
After the production, the algae biomass is harvested and processed. The cells are gently separated from the suspension, dehydrated by a spray drying process and the astaxanthin extracted without solvents. This process leaves no residue. The resulting high-purity oleoresin, a fatty astaxanthine extract, serves as a raw material for the production of the final nutritional supplement.
