Reduction of sterols and other compounds from oils
A process for the removal of sterols, specifically cholesterol, from a triglyceride oil, preferably a marine triglyceride oil, said process comprising contacting an oil with an adsorbent, specifically TRIS YL™, clay or a mixture thereof, heating the mixture to 100° C. to 210° C., preferably 150° C. to 170° C., preferably for a time period of greater than one minute and optionally at a pressure less than 133 Pa, preferably less than 1.33 Pa.
1. A composition comprising a oil, wherein the composition comprises less than about 2 mg of free and bound cholesterol per gram of composition, from about 250 to about 700 mg EPA and DHA per gram of composition, and less than or equal to about 2 wt. % trans fatty acids, and wherein the oil has not been steam deodorized.
2. The composition of claim 1 , wherein the oil comprises a marine oil.
3. The composition of claim 2 , wherein the marine oil comprises a fish oil.
4. The composition of claim 3 , wherein the fish oil comprises tuna oil, menhaden oil, sardine oil, anchovy oil, mackerel oil, or a combination thereof.
5. The composition of claim 1 , wherein the oil comprises a plant oil.
6. The composition of claim 1 , wherein the oil comprises a microbial oil.
7. The composition of claim 1 , wherein the composition comprises an EPA to DHA wt. % ratio of about 60:0.3, about 18:12, about 5:25, or about 0.8:60.
8. The composition of claim 1 , wherein the composition comprises from about 1.1 to about 0.9 milligrams of free and bound cholesterol per gram of the composition.
9. The composition of claim 1 , wherein the composition comprises about 1.0 milligram of free and bound cholesterol per gram of the composition.
10. The composition of claim 1 , wherein the composition has a Gardner color of less than or equal to about 5, as determined by ASTM D 1544.
11. The composition of claim 1 , wherein the composition comprises eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), docosapentaenoic acid (DPA), residues, derivatives, or mixtures thereof.
