Resumen

Plant-based beverages have been positioned as an alternative to cow's milk. One of the most consumed plant-based beverages are those made with soybeans. Soybean beverages may be an important source of essential elements. However, the soybean plant is exposed to high amounts of contaminants from the soil and the environment, such as toxic metals. For this reason, the objective of this study is to determine the content of potentially toxic elements (PTEs) (Fe, Cu, Cr, Co, Mn, Mo, Zn, B, Ba, Ni , Li, Sr, V, Al, Cd, Pb) in order to evaluate the human exposure and the toxic risk from the consumption of these products. A total of 40 samples of different brands of soybean beverages were analyzed by ICP-OES (inductively coupled plasma - optical emission spectroscopy). The most notable PTEs is Al (3.93 mg/L), followed by Fe (1.91 mg/L) and Ba (0.69 mg/L). Considering a mean consumption of two serving per day (250 mL/serving), soybean beverages would contribute to the dietary intake of essential elements such as Fe and Mn. This consumption would mean considerable percentages of contribution to the maximum intakes of Al and Pb, which do not exceed the maximum values ​​indicated, but in cases of higher consumption these values could be exceeded with the consequent risk to public health.
