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

Abstract

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.

Heavy Metal Removal from Commercially-available Fruit Juice Packaged Products by Citric Acid

“…Fruit juices are a highly appreciated, tasty food and usually have exceptional nutritional qualities. However, they can be a potential source of toxic elements, some of them having an accumulative effect or leading to nutritional problems due to the low concentrations of essential elements, justifying the control of mineral composition in juice [2][3][4] . In Iran just like most of other countries fruit juices are the usual beverages, and used in most of the festivals, ceremonies and celebrations and even in hospitals and schools.…”

“…They are served in dinner or lunch with biscuits, snacks or pastries and occasionally with breads. However, they can be a potential source of toxic elements, some of them having an accumulative effect or leading to nutritional problems due to the low concentrations of essential elements, justifying the control of mineral composition in juice [2][3][4] . Chemicals may be encountered as reactants, solvents, catalysts, inhibitors, as starting materials, finished products, by-products, contaminants, or off-specification products.…”

Determination of trace metals in fruit juices in the Portuguese market

“…When consumed in moderation as part of a balanced diet, fruit juices have a positive effect on, promoting health and reducing disease risk [ 2 ]. However, they can be a potential source of toxic elements, some of them having a cumulative effect or leading to nutritional problems due to low or high concentration of essential elements [ 3 ].…”

Quantification of Arsenic, Cadmium, Mercury and Lead in Pineapple: Method Development, Validation and Evaluation of In-House Reference Materials

“…The determination of As, Cd, Hg, and Pb in food is a well-documented topic [8][9][10][11] due to the impact that these elements have on the health of human beings. The analytical methods used for quantification of these toxic elements in food are numerous and based on elemental techniques such as graphite furnace atomic absorption (GFAA), 12 cold vapor atomic absorption (CVAA), 3 high-resolution continuum-source atomic absorption spectroscopy (HR-CS AAS) 13 and inductively coupled plasma with optical emission (ICP OES) or mass spectrometry detection (ICP-MS).…”
