Utilization of highly deoxynivalenol – contaminated wheat viaextrusion processing.

The effects of sodium bisulfite and extrusion cooking under high temperature and pressure on DON levels in wheat grain and mill fractions was investigated.  Samples of highly naturally DON contaminated soft winter wheat were soaked for 1 hr in water or aqueous sodium bisulfite solutions and extruded.  The soaking treatment with sodium bisulfite solution (5% SO2 equivalent) lowered DON from 7.3 to 0.8 mg/kg without extrusion and to 0.3 mg/kg with an extrusion process.  When the contaminated kernels were tempered with water or sodium bisulfite solutions (5 or 10% SO2 equivalent) and milled, the flour samples showed lower levels of DON.  Extrusion of milled flour and whole meal samples, both obtained from sodium bisulfite tempered wheat, did not change DON levels significantly as compared to the nonextruded milled flour and whole meal samples.
