Abstract: A process for removing unwanted odours from mixtures of fatty acid esters which, besides other components, contain the esters of highly unsaturated fatty acids, especially of highly unsaturated omega -3-fatty acids, such as eicosapentaenoic acid or docosahexaenoic acid, is characterised in that the mixture of fatty acid esters is treated with complex hydrides, in particular with sodium borohydride solution. The process is particularly suitable for removing unwanted odours from mixtures of fatty acid esters which have been obtained from fish oil, for example from fish oil by transesterification with alkanols with 1 to 3 C atoms.

Abstract: Organic materials which contain from 0.001 to 10% by weight of an aminoreductone I I where R1, R2 and R3 are H, methyl or ethyl and R4 is the radical of a naturally occurring .alpha.- or .beta.-aminoacid or of a C1-C10-alkyl ester thereof or, in the case of an .alpha.aminoacid, a lactone having a 2-OH group in the cyclohexenone ring, or R4 is C1-C20-alkyl which is unsubstituted or substituted by -OH, C1-C4-alkoxy or C1-C4-acyloxy, or is -(CH2-CH2-O)nH, which may be etherified with a C1-C4-alkanol or esterified with a C1-C4-fatty acid, and where n is from 2 to 10, or a mineral salt thereof. Novel compounds Ia differ from I in having the radical R4a, where R4a is R4 with the exception of methyl. Compounds I are prepared by reacting the corresponding 2,3-dihydroxycyclohex-2-en-1-one with an amine HN(R3)R4 or a mineral acid salt thereof. 25.
