Selenium is a trace element of extreme importance, because the
low concentration of selenium in the body can be considered a risk
factor for cancer, cardiovascular disease, thyroid and viral infection.
In this study, there was no detection of selenium in any of
the samples analyzed, since the quantification limit of the method
was 0.082 mg/L, similar to the concentration contained in the standard
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 level
imposed by legislation. Therefore, it the use of more sensitive
analytical method for quantifying the content of Se in the sample
is required
