Among the thousands of existing rice varieties, aromatic rice has increasingly attracted consumer’s preference in recent years. Within aromatic rice, Basmati, cultivated in some regions in Pakistan and India, seems to be the most highly demanded. Other aromatic rice, cultivated in specific regions, for instance in Thailand (commonly referred to as Jasmin Thai rice), are also highly appreciated by consumers. In this work, the elemental profiles of commercially available rice samples (17 Basmati, 11 Thai and 7 Long Grain rice), were determined by Energy Dispersive-X Ray Fluorescence (ED-XRF) spectroscopy. The mass fractions of P, Cl, S, K, Fe, Cu and Zn were significantly different (95 % confidence interval) between Basmati and Thai rice and between Thai and Long Grain rice; only Cl, S and Zn were significantly different between Basmati and Long Grain rice. Multivariate evaluation of the results combining Soft Independent Modelling by Class Analogy (SIMCA) and Partial Least Square-Discriminant Analysis (PLS-DA), allowed the correct classification (true positives) of 94.1, 85.6 and 100 % of the Basmati, Long Grain and Thai rice, respectively. The specificity (true negatives) of Basmati, Long Grain and Thai, was 94.4, 82.1 and 100 %, respectively.
