The aroma-active compounds potentially important to Parmigiano Reggiano cheese were studied using a dynamic headspace–gas chromatography–olfactometry (GC–O–DH) technique. The aroma contribution was evaluated by both Osme and AEDA technique. The Osme values were based on a 10 point scale, while the ﬂavour dilution values of AEDA were obtained by sequentially reducing the sample size at a ﬁxed purge gas volume. In general, aroma compounds with high Osme values also had high FD values. Among the aroma compounds identiﬁed in Parmigiano Reggiano cheese, acetaldehyde, 2-methylpropanal, 2-methylbutanal, 3-methylbutanal, ethyl butanoate, ethyl hexanoate, ethyl octanoate, methional, dimethyl trisulphide, diacetyl, and 2,6-dimethylpyrazine were considered the most odour-potent.
