Abstract
Official abstract text for this publication.
The present invention includes methods for producing and purifying esters of polyunsaturated fatty acids that include reacting a composition having triglycerides with polyunsaturated fatty acid residues in the presence of an alcohol and a base to produce an ester of a polyunsaturated fatty acid from the triglycerides. The composition can be a polyunsaturated fatty acid-containing composition that has not been conventionally processed. The reacted composition can be further processed by distillation.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising at least 90 wt. % ethyl ester of docosahexaenoic acid, wherein the composition further comprises at least 0.1 wt. % of docosapentaenoic acid (n-3) or an ester thereof; wherein said composition is from a single microorganism source and said single microorganism is of the genus Crypthecodinium or Schizochytrium. 2. A composition comprising at least 70 wt. % ethyl ester of docosahexaenoic acid and at least 25 wt. % ethyl ester of docosapentaenoic acid (n-6); wherein said composition is from a single microorganism source and said single microorganism is of the genus Schizochytrium or Thraustochytrium. 3. A product comprising a composition according to claim 1 , wherein said product is selected from baked goods, vitamin supplements, diet supplements, and powdered drinks. 4. A food product comprising a composition according to claim 2 . 5. The composition according to claim 2 , wherein the microorganism is Schizochytrium sp. 6. The composition according to claim 1 , wherein the microorganism is Crypthecodinium cohnii or Schizochytrium sp.
