Sequential treatment of hydrogen peroxide, vacuum packaging, and dry heat for inactivating Salmonella Typhimurium on alfalfa seeds without detrimental effect on seeds viability

The aim of this study was to inactivate Salmonella Typhimurium loaded onto alfalfa seeds with sequential treatment of hydrogen peroxide, drying, vacuum packaging, and dry heat. Also, we verified the effect of vacuum packaging in dry heat treatment. Populations of Salmonella on alfalfa seeds after sequential treatment were not detected after 8 or 3 h of dry heat treatment at 70 or 73 °C. Salmonella populations including injured cells were also...
