Abstract
A method of isolating nutraceuticals products from algae is provided. A method of isolating carotenoids and omega-3 rich oil from algae includes dewatering substantially intact algal cells to make an algal biomass and adding a first ethanol fraction to the algal biomass. The method also includes separating a first substantially solid biomass fraction from a first substantially liquid fraction comprising proteins and combining the first substantially solid biomass fraction with a second ethanol fraction. The method further includes separating a second substantially solid biomass fraction from a second substantially liquid fraction comprising polar lipids and combining the second substantially solid biomass fraction with a third ethanol solvent fraction. The method also includes separating a third substantially solid biomass fraction from a third substantially liquid fraction comprising neutral lipids, wherein the third substantially solid biomass fraction comprises carbohydrates and separating the neutral lipids into carotenoids and omega-3 rich oil.
