Mycotoxins are toxic secondary metabolites produced by fungi, which contaminate food and feed, and pose a significant threat to human and animal health. The elimination of mycotoxins has become a major challenge in food safety and security.
Recently, graphene oxide and activated bentonites have been proposed as promising materials for mycotoxin elimination. Graphene oxide has a high surface area, and its hydrophobic and hydrophilic properties make it suitable for the adsorption of a wide range of mycotoxins. Activated bentonites, on the other hand, have a high cation exchange capacity and can effectively bind mycotoxins.
The use of graphene oxide and activated bentonites for mycotoxin elimination represents a new approach in the state of the art. These materials have several advantages over traditional methods, such as high selectivity, efficiency, and safety. However, further research is needed to optimize the use of these materials and to assess their potential impacts on food quality and safety.
Bentonites are clay minerals that have been widely used for the elimination of mycotoxins in animal feed. Bentonites have a high adsorption capacity due to their layered structure, which allows them to bind to mycotoxins and prevent their absorption by animals.
Activated bentonites have been shown to be even more effective in mycotoxins elimination. By modifying the structure of bentonites, their surface area and porosity can be increased, leading to a higher adsorption capacity.
The aim of the research is to develop a revolutionary absorber of mycotoxins, based on activated and purified clay, which will have a high affinity for economically important mycotoxins.
