Organic materials, comprising a mixture of at least two products (I) and (II), both containing isomers of conjugated long chain polyunsaturated fatty acids moieties (L1) and (L2) can be obtained by subjecting an organic material, selected from free fatty acids, mono-, di- or triglycerides, phospholipids, alkylesters 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 (L1) and (L2), so that original ratio L1/L2 = X A in starting material is increased to X B, wherein X B >= 1.1 X A.
On peut obtenir des matières organiques, lesquelles comprennent un mélange d'au moins deux produits (I) et (II) contenant chacun des isomères des fractions (L1) et (L2) acides gras polyinsaturés à chaîne longue, en soumettant une matière organique, choisie parmi des acides gras libres, des mono, di ou triglycérides, des phospholipides, des alkylesters ou des esters de paraffine, lesquels contiennent au moins 5 % en poids de ces acides gras polyinsaturés conjugués, à une conversion enzymatique (acidolyse, alcoolyse, estérification, hydrolyse), à l'aide d'une enzyme pouvant établir une distinction entre (L1) et (L2), de façon à augmenter le rapport original L1/L2 = XA dans la matière de départ, pour que celui-ci atteigne XB, XB étant >/= à 1,1 XA.
