    • PURPOSE: The derivatives of conjugated linoleic acid(CLA) and a manufacturing method thereof are provided, which can be easily added to food or oil and fat, and enhance a function of linoleic acid. CONSTITUTION: A conjugated linoleic acid(CLA) is produced by alkaline isomerization of linoleum acid. And the derivatives of CLA which improve the functions of CLA, are produced by adding a functional group to carboxy terminus of CLA. To generate the neutral lipid derivatives of CLA, triglyceride added to CLA is synthesized, or some fatty acid included in neutral lipids, such as cottonseed oil, corn oil, fish oil or lard is substituted for CLA by transesterification using a chemical method or an enzymatic method. Triglyceride derivative of CLA can be generated by chemical, enzymatic or biological method. Glycolipid derivatives of CLA can be generated in the form of ascorbic acid derivative, D-glucose derivative, and cyclodextrin micro capsule. Phospholipid derivatives of CLA are phospholipid of which fatty acid is substituted for CLA.
