Abstract:
1. A method of concentrating minor components present in crude natural oil comprising: (a) combining the crude natural oil and a solvent and cooling the resulting mixture to below 0 degrees Centigrade at a first cooling rate of greater than 1 degree Centigrade per minute and a second cooling rate of less than 1 degree Centigrade per minute to form a primarily amorphous solid complex of the oil and solvent in a liquid oil solution; and (b) separating the solid complex from the liquid oil solution to form a concentrated minor component oil separate from the solid complex; and (c) performing a chemical extraction on the concentrated minor component oil, wherein said chemical extraction is selected from the group consisting of a saponification or an esterification reaction; wherein the concentrated minor component oil comprises at least (i) 22% tocols, (ii) 8% phytosterol, (iii) 7% b-carotene, (iv) 3% lutein, (v) 15% squalene, (vi) 0.5% co-enzyme Q10 and less than 50% free fatty acids by weight after a final drying step.
