Abstract

Investigation of grain samples has revealed that Penicillium verrucosum is the main, if not the only, producer of ochratoxin A to European cereals. P. verrucosum was a very competitive fungus during certain circumstances, which may explain its role as the most important producer in grain. The sources of infection of the grain are the contaminated environments of combines, dryers, and silos. A developed mathematical model has been developed to predict the safe storage time at different moisture contents and temperatures. Different biocides, preservatives, and lactic acid bacteria have been tested for inhibition of fungal growth and toxin production. Rapid monitoring methods have been developed for both the producing fungi and ochratoxin A. Examining the fate of ochratoxin during milling revealed white flour being the only fraction with a significant reduction of ochratoxin A of about 50%. Process temperature during malting has an important effect on ochratoxin production.
