Mono- and sesquiterpenoid fingerprinting: A powerful and streamlined solution for pine nut authentication

This study proposes a novel authentication method for pine nut geographical and botanical origin, using mono- and sesquiterpene fingerprints (extracted ion chromatograms from specific ions) analysed via solid-phase microextraction coupled with gas chromatography–mass spectrometry, combined with chem...
