Refined oil compositions and methods for making

Abstract

A refined oil comprising at least one polyunsaturated fatty acid (PUFA), wherein the oil has a fatty acid ester of monochloropropanediol, epoxypropanol, and mixtures thereof in an amount of 10 ppm or less, and processes for producing the oil. The oil is preferably a microbial or marine oil.

         2 . The oil of  claim 1 , wherein the fatty acid ester of monochloropropanediol is bound 2-monochloropropane-1,2-diol (2-MCPD) and/or bound 3-monochloropropane-1,2-diol (3-MCPD). 
     
     
         3 . The oil according to  claim 1 , wherein the fatty acid ester of epoxypropanol is bound 2,3-epoxy-1-propanol. 
     
     
         4 . The oil according to  claim 1 , wherein the fatty acid ester is in an amount of 1 ppm or less. 
     
     
         5 . The oil according to  claim 1 , wherein the fatty acid ester is in an amount of 0.3 ppm or less. 
     
     
         6 . The oil according to  claim 1 , wherein the fatty acid ester is in an amount of 0.1 ppm or less. 
     
     
         7 . The oil according to  claim 1 , wherein the oil has an anisidine value (AnV) of less than 20. 
     
     
         8 . The oil according to  claim 1 , wherein the oil has an anisidine value of less than 10. 
     
     
         9 . The oil according to  claim 1 , wherein the PUFA is an omega-3 fatty acid, an omega-6 fatty acid, and mixtures thereof. 
     
     
         10 . The oil according to  claim 1 , wherein the PUFA is arachidonic acid (ARA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and combinations thereof. 
     
     
         11 . The oil according to  claim 1 , wherein the oil comprises at least 35% of a desired PUFA. 
     
     
         12 . The oil according to  claim 1 , wherein the oil comprises at least 40% of a desired PUFA. 
     
     
         13 . The oil according to  claim 1 , wherein the oil is a microbial or marine oil. 
     
     
         14 . The oil according to  claim 13 , wherein the oil is a microbial oil. 
     
     
         15 . The oil according to  claim 14 , wherein the oil has been produced by a microorganism, wherein the microorganism is selected from the group comprising microalgae, bacteria, fungi and protists. 
     
     
         16 . The oil according to  claim 15 , wherein the microorganism is of the genus  Crypthecodinium.    
     
     
         17 . The oil according to  claim 16 , wherein the microorganism is of the species  Crypthecodinium cohnii.    
     
     
         18 . The oil according to  claim 15 , wherein the microorganism is of the genus  Thraustochytrium.    
     
     
         19 . The oil according to  claim 18 , wherein the microorganism is of the species  Schizochytrium  sp. 
     
     
         20 . The oil according to  claim 15 , wherein the microorganism is of the genus  Mortierella.
