Abstract
Dried fruits are one of the most frequently consumed products by the population. Drying fruits prolongs their shelf life and also concentrates more nutrients. However, these products may contain dangerous levels of trace elements that can be harmful to health. The content of trace elements (Al, B, Ba, Cd, Cr, Li, Ni, Pb, Sr, V) in 42 samples of different dried fruits (dates, prunes, sultanas, dried apricot kernels, and dried figs) was determined by inductively coupled plasma spectrometry (ICP-OES). The concentrations of Al found in prunes (12.7 ± 5.13 mg Al/kg) and the concentrations of B found in dried plums (6.26 ± 4.45 mg B/kg) were significantly higher (p < 0.05). Regarding the risk assessment, the percentages of contribution to the maximum recommended intakes by Li in all the dried fruits studied stand out, reaching 35.3% in the case of dried plums. This study concludes that the recommended daily intake of dried fruit (30 g/day) does not pose a toxicological risk about these trace elements.
