36 Claims

1. A method for production of a low chlorophyll, enhanced polar lipids content oil composition comprising:

a. Obtaining an algal biomass

b. Extracting the algal biomass with a polar solvent to form a polar extract of algal lipids with a low water content;

c. Further extracting the polar extract with an organic solvent to separate out a fraction of non-polar lipids, thus substantially removing a non-polar lipids fraction in an organic solvent layer;

d. separating out a polar layer containing pigments and polar lipids;

e. adding water to the polar layer and further extracting with sequential additions of the organic solvent, whereby a pigment fraction is substantially removed to form a water-polar layer containing the polar lipids; and,

f. separating out a polar lipids fraction from the water-polar layer by evaporation and segregating the low chlorophyll enhanced polar lipids content oil composition produced.
