Another important milestone towards Omega-3 derived from microalgae

Just like nature all around us at the beginning of this sunny summer, our Nannochloropsis spp. microalgae have thrived in photobioreactors, and the sibiotech research team has been able to “harvest” a rich algae crop!
To obtain the valuable Omega-3 fatty acids, several significant and carefully monitored steps are undertaken:
✅ the microalgae are separated from the medium in specially equipped machinery;
✅ a microalgae concentrate is obtained, which is then freeze-dried (lyophilised);
✅ from the resulting dry biomass, highly concentrated Omega-3 fatty acids (lipid extract) are extracted using the supercritical carbon dioxide (CO2) extraction method. This extract contains eicosapentaenoic acid (EPA), one of the most valuable fatty acids for promoting cardiovascular health!
To determine the quantity and types of valuable bioactive substances obtained, the extract will be sent to the laboratory.
sibiotech algae expert, biotechnologist Liene Patetko, closely monitors the development of the microalgae – from the growth conditions and other process quality indicators from the “birth” stage to the final health-promoting product.
