<P>PROBLEM TO BE SOLVED: To provide conjugated long chain polyunsaturated fatty acids good for health. <P>SOLUTION: Organic materials, comprising a mixture of at least two products (I) and (II), both containing isomers of conjugated long chain polyunsaturated fatty acids moieties (L<SB>1</SB>) and (L<SB>2</SB>) can be obtained by subjecting an organic material, selected from free fatty acids, mono, di, or triglycerides, phospholipids, alkyl esters or wax esters, containing at least 5 wt.% of these conjugated polyunsaturated fatty acids, to an enzymic conversion (acidolysis, alcoholysis, esterification, hydrolysis) using an enzyme that can be discriminated between (L<SB>1</SB>) and (L<SB>2</SB>), so that original ratio L<SB>1</SB>/L<SB>2</SB>=X<SB>A</SB>in starting material is increased to XB, whrein X<SB>B</SB>≥X<SB>A</SB>. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
