    摘要： 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.

    摘要： Triglycerides, that have at least two long chain polyunsaturated fatty acids L1 and L2, from which at least one is present for more than 20 wt %, while the weight ratio L1:L2 is at least 2 and which triglycerides also contain at least 2 wt % of saturated fatty acids with 2-12 and/or 20-24 C-atoms, but not more than 10 wt % of saturated fatty acids with 16-18 C-atoms, while at least 5 wt % of the saturated C2-C12 or C20-C24 fatty acid residues is bonded on a triglyceride molecule, wherein at least L1 and/or L2 is present, display a number of advantageous properties (e.g. higher oxidative stability, healthier, lower caloric, structuring properties, digestibility).
