Materials, enriched in long chain polyunsaturated fatty acids (=LCPUFA's) are obtained from a material A, containing ≥5 % LCPUFA's and comprising ≥2 LCPUFA's (L1 and L2) in a ratio XA by splitting A into parts B and C, so that B has ratio L1:L2=XB, which is at least 1.5 times XA, while C has ratio L1:L2=XC that is « 0.7 times XA; whereupon component B is split into components D and E: D having a total LCPUFA-content that is ⊃1.2 times its content in B; and/or component C is split into components F and G, F having an LCPUFA-content that is » 1.2 times its content in C. |
