Agents of different origins for reduction of mycotoxins’ level in feed

Abstract Toxic secondary metabolites of some fungi (mainly representatives of Alternaria, Aspergillus, Fusarium and Penicillium genera) may contaminate agricultural products, representing serious health hazards both to humans and animals. Along with this, the economic losses due to the mycotoxins’ presence in feed production, including crop and animal feedstuff processing and distribution, motivated the plentiful research of detoxification strategies. Feed supplementation with mineral adsorbents (zeolites, hydrated sodium calcium aluminosilicate (HSCAS), bentonites, etc.) is the most prominent approach widely applied. Besides these, other products for mycotoxin level reduction based on the constituents of the yeast cell wall or Lactobacilli are often used. Recently, many investigations are directed toward plant-derived products that can efficiently adsorb mycotoxins in their native (biosorbents) or modified forms (e.g. activated carbon, biochar etc.). These renewable, easily accessible and readily prepared sorbents are economically viable and safe alternatives for mycotoxin decontamination of feed resources. Organic polymers (chitosan, cellulose, etc.) as well as synthetic polymers, such as polyvinyl pyrrolidine, also might reduce mycotoxins’ level in feed. Besides these conventional methods, new research trends are nanotechnologies, the promising, effective, low-cost way for mycotoxins’ removal. This overview systematically summarizes information on binding agents of different origins for the reduction of mycotoxins’ levels in feed. Furthermore, the knowledge of potential applications of binding agents in the feed industry is also reviewed and discussed.
