Development of a CE-UV methodology for the evaluation of the addition of adsorbents in animal feed for the removal of mycotoxins: effect on the levels of B-complex vitamins

Resumo

Mycotoxins are toxic substances produced by fungi metabolism and can be eventually found in animal feed, leading to potential harm in animal health. Adsorbent products are added during the production of feed in order to remove mycotoxins. However, scientific reports indicate that they can also remove some essential nutrients for health, such as vitamins, lowering the nutritional value of the animal feed. The aim of the present work is to apply Micellar Electrokinetic Capillary Chromatography (MEKC) as a tool to determinate the levels of B vitamins present in in vitro samples, simulating animal digestion of feed containing different adsorbents.
