Influence of processing on Fusarium mycotoxins in contaminated grains
1996
Bennett, G.A. | Richard, J.L.
Effects of processing on Fusarium mycotoxins (zearalenone, deoxynivalenol and fumonisins) in naturally contaminated corn and wheat are reviewed. Processing methods considered are wet milling, dry milling and ethanol fermentation. The mycotoxins survive most of the processing methods and the ethanol fermentations. Stability of the fungal metabolites is of concern because some products, such as gluten from wet milling and distillers and dried grains from fermentation of contaminated grains, contain higher levels of toxin than found in the original grain. However, beneficial aspects of processing are realized by the production of toxin-free starch from wet milling of zearalenone- and fumonisin-contaminated wet corn. Possible future strategies that could be used to reduce the level of toxin contamination in milling and fermentation products are discussed.
