We used NMR and chemometrics to demontsrate that it is possible to detect turmeric adulteration (even at low levels) in Italian saffron, here the open access publication we made in collabroation with the University of Bolzano: Angeli, L., Cruz Muñoz, E., Ballabio, D., Morozova, K., Scampicchio, M. (2026) 1H NMR spectroscopy combined with chemometrics for detection of turmeric adulteration in Italian saffron (Crocus sativus L.), Food Control, 179, 111560 [link]
