Short Communication: Quantification of the Effect of Mycotoxin Binders on the Bioavailability of Fat-Soluble Vitamins In Vitro

Mycotoxins are frequently found in animal feeds. Mycotoxicosis are often subclinical
and difficult to diagnose, but result in important production losses. Mycotoxin binders are used to
reduce their impact on health and performance. However, the unspecific mechanism of adsorption may
also bind other essential nutrients, including vitamins. The aim of this study was to evaluate the effect
of six mycotoxin binders on the bioavailability of fat-soluble vitamins by simulating the gastro intestinal
digestion in vitro. The adsorption tests indicate that many mycotoxin binders adsorb a considerable
proportion of vitamin E but not vitamin D, whereas the low recovery rate of vitamin A did not allow
the quantification of its adsorption.
