Gas chromatography–olfactometry with aroma extract dilution of peppermint essential oils, including oil from Piedmont in Italy, found the highest flavour dilution factors for 1,8-cineole (eucalyptus, fresh, camphoraceous), menthone (minty, herbaceous) and menthofuran (minty, musty, petroleum-like), among potent odorants the authors identified tentatively.
SCOPE
Essential oils, not fresh leaves; the study set out to tell Piedmont oil from others, and its potent odorants are tentatively identified.
SUPPORT CHECK
The statement the claim rests on was found word for word in the abstract fetched from the named service, and an editor read the full abstract against every part of the claim. Abstract from Europe PMC (ebi.ac.uk/europepmc).
Chemical fingerprinting strategies based on comprehensive two-dimensional gas chromatography combined with gas chromatography-olfactometry to capture the unique signature of Piemonte peppermint essential oil (Mentha x piperita var Italo-Mitcham)
