Soft‐electron is a term referring to electrons with energies of 300 kV or lower. Enrei and Vinton soybeans were irradiated with gamma–rays and soft–electrons at 60 keV to compare the effectiveness of the treatments for decontamination purpose. The doses of 20 kGy of gamma‐rays and 26 kGy of soft‐electrons were effective to decontaminate the soybeans. The gamma radiation changed some properties of the grains: inhibited the germination capacity, increased the lipid oxidation and decreased the lipoxygenase activity, radical scavenging activity and carotenoid content. Soft‐electron treatment caused less or none change in soybean quality, being considered a more appropriate procedure for decontamination.
