Abstract

Novel compositions containing conjugated linoleic acid isomers can be used for controls in gas chromatography and for animal feeding studies. Purified isomers of conjugated linoleic acid can be treated to produce a preparation containing two isomers of CLA. The preparation can be used as it is or further processed to separate the two isomers. The isomers can be used in their free fatty acid form or converted to alkylesters or triglycerides. Furthermore, the isomers are useful as supplements for food products or feed.
