Novel compositions containing conjugated linoleic acids are efficacious as animal feed additives and human dietary supplements. Linoleic acid is converted to its conjugated forms in which the resulting composition is low in certain unusual isomers compared to conventional conjugated linoleic products. In addition, the inventions provides compositions that are prepared according to a novel method that controls oxidation of CLA into volatile organic compounds as well as containing metal oxidant chelators to control oxidation during storage.

Conjugated linoleic acid compositions

The present invention relates the manufacture of conjugated linoleic acid, and in particular, to feeds and food products containing conjugated linoleic acid. Accordingly, processes for producing conjugated linoleic acid of high purity are disclosed. These processes utilize alcoholate catalysts and esters of sunflower oil, safflower oil, or corn oil as the source of linoleic acid. The esters of conjugated linoleic acid produced by the process can be used in animal feeds and in food products suitable for human consumption. Furthermore, the esters can be converted into free fatty acids or incorporated into triglycerides.

Novel acylglycerides are disclosed comprising mono-, di- and triacylglycerides characterized by predominantly containing the conjugated linoleic acids t9,c11- and c10,t12 octadecadienoic acids to the exclusion of 11,13-, 8,10- and trans,trans isomers.

Triacylglycerols of enriched CLA content

Novel compositions containing conjugated linoleic acids are efficacious as animal feed additives and human dietary supplements. Linoleic acid is converted to its conjugated forms in which the resulting composition is low in certain unusual isomers compared to conventional conjugated linoleic products.

Compositions and methods of using conjugated linoleic acid preparations enriched for the t10,c12 and c9,t11 isomers are disclosed. It is found that preparations of conjugated linoleic acid containing a ratio of t10,c12 to c9,t11 of about greater than 1.2:1 are desirable for a wide variety of nutritional, therapeutic and pharmacologic uses.

Isomer enriched conjugated linoleic acid compositions

Methods of using isomer enriched conjugated linoleic acid compositions

A novel method of delivering conjugated linoleic acid to an animal involves compounding feed or food for human consumption with a biologically active amount of conjugated linoleic acid alkyl ester (CLA-ester). The CLA-ester comprises a mixture of c9,t11-octadecanoic acid and t10,c12-octadecanoic acid, with contaminating isomers being present at an aggregate percentage of less than 5. Manufactured from sunflower or safflower oil, the CLA-esters contain less than 0.5 percent phosphatidyl residue, so that a food grade product is made without special purification and refining steps.
