ABSTRACT
In this study, we investigated the levels of macro, minor, and trace elements in roasted ground and instant coffees (n = 56). We assessed dietary mineral intake and health risks associated with potentially toxic elements (PTEs) using deterministic and probabilistic approaches. The limits of detection (LOD) ranged from 0.13 µg/kg for Be to 3.7 mg/kg for K, with corresponding limits of quantification (LOQ) at 0.43 µg/kg and 12.2 mg/kg. The recovery values (R%) ranged from 89 to 107%. The most abundant element was K, followed by Mg, Ca, and Na. Other elements followed this order Fe > Mn > B > Cu > Sr > Zn > Al > Ba > Ni > Cr > Co > Se > Sn > Pb > Li > Ag > V > As > Cd > Hg > Be. Instant coffees generally exhibited higher K, Mg, and Na levels than ground-roasted coffees. Notably, Hg, Li, and Se were not detected in 34, 2, and 1 samples, respectively. Coffee samples were generally a good source of dietary elements such as Cu, Mn, Cr, and Se. The PTEs found in coffee products posed negligible risks to human health. The total target hazard quotient (TTHQ) remained below 1, and the incremental lifetime cancer risk (ILCR) did not exceed the threshold of 1 × 10-6. Nevertheless, coffee consumption contributed to Pb and As levels below 15% of the benchmark dose lower confidence limit (BMDL) values, and Sn, Hg, and Cd levels below 0.90% of the provisional tolerable weekly intake (PTWI).
