In vitro evaluation of sequestering agents for aflatoxins
The contamination of animal feed with mycotoxins represents a worldwide problem that causes serious diseases in animals and economic losses. One of the most used methods for protecting animals against mycotoxins is the utilization of adsorbents. These are inorganic or organic components that added to foods form complexes with mycotoxins in the gastrointestinal tract thus decreasing its absorption. Four mycotoxin binder products including two hydrated sodium calcium aluminosilicates, one esterified glucomannan and one multi modular were used to determine their efficacity to bind aflatoxin B1. The binding ability for AFB1 was conducted by an in vitro assay, which simulated the pH condition of the gastrointestinal tract of animals. AFB1 contents was determinated by high performance liquid chromatographic (HPLC). With the exception of the esterified glucomannan product, the binding percent of AFB1 was high (> 76%) by the sequestering agents used in the current study. These results suggest that most commercial adsorbent products used in this study are potential chemical - biological agents that might be used to decrease the effects of aflatoxins in animals.
