Abstract
Fatty methyl esters can be prepared easily by direct acid transesterif ication. If conjugated fatty acids are present, soft techniques must b e used, In spite of new polar phases and capillary columns, the comple te separation of all the fatty acids cannot be obtained by GC. However , the resolve some of the isomers, The derivatisation utilisation of s ilver ion HPLC and TLC helps to of fatty acids in DMOX, picolinyl and MTA derivates enable the determination of the double position by GC-MS , GC-FTIR achieved the determination of the geometrical configuration.
