Mycotoxins in malting and brewing: is every sample contaminated with mycotoxins? (poster)

Original language description

Mycotoxins are secondary metabolites of fungi and represent a serious problem for human health . Dueto growing interest ,various aspects have been widely studied by scientific groups. One of these aspects relates to the food industry and associated beer production. Mycotoxins can be present in the basic raw materials for beer production as well as in the brewed beer. Problematic mycotoxins that pose a serious risk of toxicity are aflatoxins especially aflatoxin B1(AFB1), fumonisins(FBs), zearalenone(ZEN) and its metabolites, deoxynivalenol(DON) including its acetylated forms and also the modified form deoxynivalenol-3-glucoside(DON-3G),T-2toxin,HT2 toxin and ochratoxin A. The Research Institute of Brewing and Malting has been dealing with the mycotoxin issue since 2008.This study describes analysis of the above mycotoxins during years2020-2024 in barley(n=775),malt(n=751)and commercially available beers(n=522) using QuEChERS, immunoaffinity columns and UPLC MS/MS. There sults showed positive samples of mycotoxins in brewing and malting matrices at the levels of μg/kg (barley,malt) and ng/Lforbeer. Therefore, determination of residual concentrations and the accurate quantitative determination of mycotoxins, correct interpretation of the results in connection with toxicological values, and the maximum permissible levels of mycotoxins play a key role in world food safety and consumer protection.
