Binding agents and deactivators

In the feed and food industry it has become common practice to add mycotoxin binding agents such as Montmorillonite or bentonite clay in order to affectively adsorb the mycotoxins.[23] To reverse the adverse effects of mycotoxins, the following criteria are used to evaluate the functionality of any binding additive:
Efficacy of active component verified by scientific data
A low effective inclusion rate
Stability over a wide pH range
High capacity to adsorb high concentrations of mycotoxins
High affinity to adsorb low concentrations of mycotoxins
Affirmation of chemical interaction between mycotoxin and adsorbent
Proven in vivo data with all major mycotoxins
Non-toxic, environmentally friendly component
Since not all mycotoxins can be bound to such agents, the latest approach to mycotoxin control is mycotoxin deactivation. By means of enzymes (esterase, epoxidase), yeast (Trichosporon mycotoxinvorans) or bacterial strains (Eubacterium BBSH 797), mycotoxins can be reduced during pre-harvesting contamination. Other removal methods include physical separation, washing, milling, heat-treatment, radiation, extraction with solvents, and the use of chemical or biological agents. Irradiation methods have proven to be effective treatment against mold growth and toxin production.[23]
