  • Patent number: 6271404
    Abstract: The invention concerns an isomerisation process, wherein materials comprising non-congugated long chain polyunsaturated fatty acids are subjected to base in the presence of an alcohol with ≧3 C-atoms and ≧2 OH groups and having ratio C-atoms: OH-groups of ≧1.25. The resulting reaction product, containing the conjugated isomers is obtained in higher yield at lower temperatures and are not contaminated by presence of non food grade solvent.

  • Patent number: 6184009
    Abstract: A process for preparing a material B comprising geometrical isomers L1 and L2 of conjugated linoleic acid moieties in a specific weight ratio of XB wherein a material A selected from free fatty acids, mono-, di- or tri-glycerides, phospholipids, alkyl esters or wax-esters containing at least 5 weight % of L1 and L2 are subjected to enzymatic conversion using an enzyme that can discriminate between L1 and L2 so that the original weight ratio of L1 to L2 of XA in the starting material is increased to XB where XB is equal to or greater than 1.1 XA. Advantageously, the isomers L1 and L2 are cis9, trans11 and trans10, cis12 linoleic acid or vice versa. The enzyme is advantageously a lipase obtained from Geotrichum candidum or Candida rugosa or a phospholipase. The starting material A may be, for example, a fish oil or vegetable oil. The resulting products may be blended with a complementary fat and may be used as foods or food supplements or in pharmaceutical compositions.
