Selenium is a trace element of extreme importance, because thelow concentration of selenium in the body can be considered a riskfactor for cancer, cardiovascular disease, thyroid and viral infec-tion. In this study, there was no detection of selenium in any of the samples analyzed, since the quantification limit of the methodwas 0.082 mg/L, similar to the concentration contained in the stan-dard reference. Law permits 0.05 mg/L as maximum in liquid food.The limit of quantification trial is 1.65 times higher than the top le-vel imposed by legislation. Therefore, it the use of more sensitiveanalytical method for quantifying the content of Se in the sampleis required
