(3R)3Hydroxy2octanone
 a mushroomlike, fresh grass odour.
Aroma extract
dilution analysis was applied to determine the
flavour dilution factors of the two enantiomers.
The flavour dilution factor of the
(R)enantiomer was 1024, which is much higher
than that of (S)enantiomer (256). Thus the
(R)enantiomer is considerably
stronger.
