A módosított, a mátrixhoz kötött és intakt mikotoxinok egységes fogalomrendszere és a mátrixhoz kötött mikotoxinok alternatív meghatározása - Rövid áttekintés

Abstract

SUMMARY The healthy organism is able to transform a relatively high proportion of mycotoxins. The original molecular form of some mycotoxins may be altered via the enzymatic xenobiotic transformation ability of the liver, or even by the intestinal microbiota, but in some instances as early as the site of production by the mould or in the host plant they may be transformed, as well. Moreover, divergent chemical effects may play a role in the modification of the original chemical form. Along this process, the emerging new molecules can be more toxic and biologically more active than the parent compound. The hidden (bound) mycotoxin theory is rather new. For the clarification of the erroneously and unequivocally used terminology in the year 2014, a new, systematic definition criterion has been worked out, in which mycotoxins are classified into four hierarchic levels, based on their formation. This mini review introduces this classification system with numerous examples and shows alternative method for the preparation of samples before analysis of matrix associated mycotoxins.
