デオキシニバレノール汚染に対応した小麦の乾燥・調製技術 Decontamination deoxynivalenol in wheat by physical methods
Deoxinivalenol(DON) concentration ratio in wheat is likely to increase during the storage stage of so called 2stage-drying. The risk of DON -increase seems to be without reference to kernel moisture content (14-18% w.b.). The increase occurred remarkably in high level of initial DON concentration over 2mg/kg. Rapid drying can prevent increase of DON concentration. <br>DON contaminated grain can be removed by some physical treatments. Sizer, gravity separator and optical (near-infrared light) sorter can reduce the concentration of DON effectively. <br>In gravity separation, the DON concentration of samples (pre-separation, accepted and rejected) are in inverse proportion to its volume weight. So the target DON concentration by gravity processing can roughly be estimated from volume weight of accepted sample.
