An aroma extract dilution analysis applied on an aroma distillate prepared from fresh apricots revealed (R)-γ-decalactone,(E)-β-damascenone, δ-decalactone, and (R/S)-linalool with the highest flavor dilution (FD) factors among the 26 odor-active compounds identified. On the basis of quantitative measurements performed by application of stable isotope dilution assays, followed by a calculation of odor activity values (OAVs), β-ionone,(Z)-1, 5- ...
