The structure-flavour relationships of some Schiff bases are discussed. The
carbonyl part - (S)-(+)/(R)-(-)-carvone - showed a greater impact on the a
roma of the imine than the amine part. The different aromas of the two enan
tiomeric Schiff bases could clearly be distinguished. No flavours similar t
o Maillard products were detected in aromatic or heteroaromatic compounds w
ith a structurally related imine unit. Some new and interesting aroma notes
were discerned.
