Abstract
Disclosed is a non-toxic omega-3 rich extract and non-toxic miscella and a method of producing same. The method may include obtaining an aqueous microalgae slurry comprising at least 65% water; mixing the aqueous microalgae slurry with ethanol for a predetermined duration; separating the aqueous microalgae slurry-ethanol mixture to liquids and miscella; and evaporating the water and the ethanol from the liquid to receive a liquid extract. In some embodiments, the miscella contains organic material and ash at an amount below 15 dry weight %.
Claims10
A method of producing non-toxic proteins and omega-3 from microalgae, the method consisting of:
- obtaining an aqueous microalgae slurry comprising at least 65% water;
- mixing the aqueous microalgae slurry with ethanol for a predetermined duration, to yield an aqueous microalgae slurry-ethanol mixture, wherein the ethanol diffuses into the cell structure of the microalgae and extracts nutritive elements from the microalgae cells through the cell membranes without disrupting the cell membranes of the microalgae;
- separating the aqueous microalgae slurry-ethanol mixture, which includes the extracted nutritive elements, to liquids and miscella;
- and
- evaporating the water and the ethanol from the liquid to receive a liquid extract,
- wherein the miscella contains organic material and ash at an amount below 15 dry weight %.
