Introduction: the pollution resulting from industrialization has led to an increase in the concentration of metals in various environments and their incorporation into raw materials and finished products, which has a direct impact on human health.
Objective: to quantify metals in the raw material used in the manufacture of the LECISAN® chewable tablet and in the tablet, to establish reference levels of: aluminum, calcium, cadmium, chromium, copper, iron, magnesium, lead, silicon, vanadium and zinc.
Method: atomic optical emission spectrometry with inductively coupled plasma (ICP OES) was used and confidence intervals for the mean of the quantified values were established using statistical methods with a probability of 95%.
Results: there are significant differences between the two presentation forms in terms of the amount of all metals, except aluminum (p<0.05). The variation coefficients were low, chromium obtained a value close to 10% in the raw material and lead was high (17.44%). The values are within the range reported as permissible according to Cuban standards (NC 493:2012) except for lead and copper. Higher concentrations of those elements with favorable health effects were observed.
Conclusions: the results found should be considered as references for the evaluation of the impact that the daily administration regimen of the LECISAN® nutritional supplement would have on health and the analysis of factors related to the presence of metals in by-products of soybean oil refining for future research.
