The present invention relates to enaminocarbonyl compounds with the formula I, in which X denotes O or CH2, Y denotes N and each of R1 and R2 denotes hydrogen, or Y denotes a CH and either R1 or R2 denotes a C1-4 alkyl, and the remaining R1 or R2 denotes hydrogen, selected (for Y denoting CH and R1 or R2 denoting a C1-4 alkyl) from a group encompassing a mixture of R and S enantiomers enriched in either enantiomer R or enantiomer S, enantiomer R and enantiomer S. The present invention also relates to the use of compounds with the formula I, in which X denotes O or CH2, Y denotes a CH and either R1 or R2 is selected from a group encompassing hydrogen and a C1-4 alkyl, and the remaining R1 or R2 denotes hydrogen, for the modification of the taste of a product and/or preparation for oral administration.
