Abstract
The main mycotoxins that occur in foods intended for human consumption or animal feed are produced by fungi of the genera Aspergillus, Penicillium and Fusarium. These substances may cause several damage to human and animal health as well as economic losses for agribusiness, as they may be present in different phases of production, affecting producers, agricultural traders and processors. The prevention of contamination is the mean way to minimize some of the risks associated with mycotoxins. However, there are situations that the presence of some mycotoxin is inevitable due to climatic and environmental conditions, even adopting the good manufacturing practices in the various steps involved. For this reason, it is highlighted the importance of the study of alternatives to reduce mycotoxin contamination in agricultural products and its products. Ozone technology has been presented as an alternative for decontamination of mycotoxins with advantage over other studied technologies. This technology does not generate toxic waste and is classified as a green technology. Studies on decontamination of mycotoxins with ozone technology, while promising, are concentrated mainly in the aflatoxins. Zearalenone (ZEA) and deoxynivalenol (DON) are mycotoxins produced by Fusarium and generea and have been found with relative frequency in agricultural products in several national and international studies. However, a smaller number of studies with decontamination of grains, their products and coproducts naturally contaminated with these mycotoxins have been observed. Thus, this research aims to study the kinetics of destruction of ZEA and DON in grains and grain-derived using ozone technology. (AU)
