However, some of these factors are uncontrollable and in certain years, crops from various geographic regions become contaminated with mycotoxins such as aflatoxins, fumonisins, zearalenone or deoxynivalenol. The result is that human foods prepared from these crops can contain one or more of these mycotoxins. To provide marketability of these contaminated crops, we have examined the distribution of these mycotoxins during processing of contaminated corn to determine those fractions that may be safely used for human foods or if further work needs to be done that would allow for removal of the mycotoxin from the fractions used in food. Those processes investigated include ethanol fermentation, wet milling, dry milling and a process of alkaline peroxide treatment in the preparation of a flour substitute prepared from oat hulls called "fluffy cellulose". We found that those fractions from processing that are used most prominently for animal feeds are usually contaminated with the specific mycotoxin investigated, and in most cases, there is a concentration of the mycotoxin in those fractions. Thus, there remains a need for decontamination procedures to eliminate these mycotoxins from animal feeds. As a result of our studies with oat hulls contaminated with deoxynivalenol for preparation of "fluffy cellulose", we determined that pretreatment can be used to eliminate or significantly reduce certain mycotoxins from grains prior to processing. |
