Rice samples cultivated in the USA, Europe and Basmati regions have been analysed using Isotope Ratio Mass
Spectrometry (IRMS) and Inductively Coupled Plasma Mass
Spectrometry (ICP-MS). Nine key variables (δ13C, δ18O, boron,
holmium, gadolinium, magnesium, rubidium, selenium and
tungsten) were identified by canonical discriminant analysis as providing the maximum discrimination between rice
samples from these regions.
