Analysis of Mineral and Heavy Metal Content of Some Commercial Fruit Juices by Inductively Coupled Plasma Mass Spectrometry

Abstract EN

The presence of potentially toxic elements and compounds in foodstuffs is of intense public interest and thus requires rapid and accurate methods to determine the levels of these contaminants.

Inductively coupled plasma mass spectrometry is a powerful tool for the determination of metals and nonmetals in fruit juices.

In this study, 21 commercial fruit juices (apple, peach, apricot, orange, kiwi, pear, pineapple, and multifruit) present on Romanian market were investigated from the heavy metals and mineral content point of view by ICP-MS.

Our obtained results were compared with those reported in literature and also with the maximum admissible limit in drinking water by USEPA and WHO.

For Mn the obtained values exceeded the limits imposed by these international organizations.

Co, Cu, Zn, As, and Cd concentrations were below the acceptable limit for drinking water for all samples while the concentrations of Ni and Pb exceeded the limits imposed by USEPA and WHO for some fruit juices.

The results obtained in this study are comparable to those found in the literature.
