“Emerging“ mycotoxins are newly appearing mycotoxins, the existence of which was previously unknown. Fusaproliferin, beauvericin, enniatins, and moniliformin are metabolites of the most frequent fungi of Fusarium spp. Only limited data on these toxins exist, however, namely enniatins were detected in cereals at relatively high concentrations. Currently, research and monitoring of these mycotoxins in various raw materials and derived products have been conducted. This study summarizes the latest knowledge about the occurrence of “emerging“ mycotoxins in brewing materials and their transmission to beer.
