Abstract

Undesirable odors are removed from fatty ester mixtures which, in addition to other components, contain the esters of highly unsaturated fatty acids, in particular of highly unsaturated 3-fatty acids, such as eicosapentaenoic acid or docosahexaenoic acid, by a process in which the fatty ester mixture is treated with a complex hydride, in particular with sodium borohydride solution. The process is particularly suitable for removing undesirable odors from fatty ester mixtures obtained from fish oil, for example by transesterification with an alkanol of 1 to 3 carbon atoms.
