Claims29
A process for remediating deoxynivalenol, wherein the process comprises:
- determining if deoxynivalenol is present in incoming grain and/or one or more biorefinery process compositions;
- and
- introducing one or more treatment compounds into at least one post-distillation, biorefinery process composition to react with at least a portion of the deoxynivalenol present in the at least one post-distillation, biorefinery composition to form a treated, post-distillation, biorefinery process composition comprising one or more reaction products, and reduce a concentration of the deoxynivalenol, wherein the at least one post-distillation, biorefinery process composition is chosen from whole stillage, thin stillage, syrup, and combinations thereof, and wherein the one or more treatment compounds comprise one or more sulfur-containing compounds that react with the at least a portion of the deoxynivalenol present in the at least one post-distillation, biorefinery composition to form deoxynivalenol sulfonate.
A process for remediating deoxynivalenol, wherein the process comprises:
- determining if deoxynivalenol is present in incoming grain and/or one or more biorefinery process compositions;
- separating whole stillage into thin stillage and wet cake;
- evaporating moisture from the thin stillage to form syrup;
- separating the syrup into a first oil fraction and a first aqueous fraction;
- and
- separating the first oil fraction into a second oil fraction and a second aqueous fraction;
- introducing one or more treatment compounds into at least one post-distillation, biorefinery process composition to react with at least a portion of the deoxynivalenol present in the at least one post-distillation, biorefinery composition to form a treated, post-distillation, biorefinery process composition comprising one or more reaction products, and reduce a concentration of the deoxynivalenol, wherein the at least one post-distillation, biorefinery process composition is chosen from the first aqueous fraction, the second aqueous fraction, the first oil fraction, the second oil fraction, and combinations thereof, and wherein the one or more treatment compounds comprise one or more sulfur-containing compounds that react with the at least a portion of the deoxynivalenol present in the at least one post-distillation, biorefinery composition to form deoxynivalenol sulfonate.
