show recoveries that were
maintained within acceptable levels. Furthermore, when it is
necessary to recover mycotoxins with different polarities, the
efficiency can be compromised due to a greater or lesser affinity of
each mycotoxin with the eluent. Such is the case in the
recuperation results, as the contamination levels increased. In
this study, AFLAM1 showed higher recoveries in comparison to AFLAB1, a fact that was already expected, since the conditions of
the official method were designed to quantify AFLAM1. However, it
was verified that AFLAB1 can also be quantified within reliable
analytical conditions.
