The disclosed subject matter relates generally to a method for modifying oil, and specifically to a process for increasing the concentration of polyunsaturated fatty acid in an oil composition.

Enzymatic modification of oil

Disclosed are methods of recovering urea from a urea/oil complex by drying the complex, combining the complex with water to form a urea solution, and removing water from the urea solution. Methods for recycling the urea in urea complexation processes are also disclosed. Also disclosed are methods of recovering polyunsaturated fatty acids or derivatives thereof from the urea/oil complexes.

Recovering urea and oil from a urea/oil complex

The disclosed matter relates to immobilized enzymes and methods of use thereof.

Immobilized enzymes and methods of using thereof

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&#x2122;, clay or a mixture thereof, heating the mixture to 100&#xb0; C. to 210&#xb0; C., preferably 150&#xb0; C. to 170&#xb0; 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.

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 absorbent, specifically TRIS YL&#x2122;, clay or a mixture thereof, heating the mixture to 100&#xb0; C. to 210&#xb0; C., preferably 150&#xb0; C. to 170&#xb0; 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.

Disclosed are methods of removing and/or reducing compounds from oils (e.g., marine oils) and oils prepared by the disclosed methods. Methods of bleaching oils are also disclosed.
