“…Activated coconut charcoal and pine biochar exhibit excellent potential for binding aflatoxin B 1 , ochratoxin A, and zearalenone and may address the need for binding materials that can bind more than one mycotoxin. Several research groups have reported that clays, carbohydrate-based sorbents, and algae biomaterials are limited in the types of mycotoxins that these materials can sequester [2,17,18,47,48].…”

“…However, these methods leave decomposition products and adducts, or can be costly for certain commodities. Clays, modified clays, carbohydrates, polymers, surfactants, and absorbing bacteria have been shown to remove levels of certain mycotoxins [2,5,17,18]. The adsorption properties and applications of these mycotoxin-binding materials are known, and there is a need for greener materials with high capacities for a range of important mycotoxins.…”

Mycotoxin sequestration materials are important tools to reduce mycotoxin illness and enable proper handling of mycotoxin-contaminated commodities. Three food-grade bentonite clays and four generally recognized as safe (GRAS) charcoal/biochar carbon materials that are marketed as feed additives and supplements were evaluated for their ability to sequester the mycotoxins aflatoxin B1, ochratoxin A, and zearalenone. The surface area of the clays varied between 32.1 to 51.4 mg2/g, and the surface area of the carbon-based materials varied from 1.7 to 1735 mg2/g. In vitro, gastric fluid studies indicated that certain pine biochar and activated coconut charcoal could sequester high amounts (85+%) of the mycotoxins at 1 ppm levels or below. However, some biochar materials with lower surface area properties lacked binding capacity. The coconut shell charcoal and pine biochar utilize agricultural waste products in a manner that significantly reduces carbon emissions and provides valuable materials to minimize exposure to toxins found in food and feed.
