One week after stored soybeans were treated with 20 ppm dichlorvos in a water emulsion, all milling and processing fractions contained residues though less than 1 ppm was present on the whole beans. Steaming did not remove residues from the dehulled meats, crude oil, or meal. Residues from the flakes passed into the miscella (extracted oil in hexane) and extracted marc (flakes with oil removed by extraction) and were subsequently detected in the crude oil and crude meal and in the hexane from both of these fractions. The residues could be removed from the hulls and crude meal by toasting and from the crude oil by refining.
