Research Note: Combination Spray Washes of Saponin with Water or Acetic Acid to Reduce Aerobic and Pathogenic Bacteria on Lean Beef Surfaces

摘要

Saponins are naturally occurring compounds known as triterpenoid glycosides found in a variety of plant species. Saponins are approved for use in the food industry as foaming agents. When combined with water or organic acid in spray treatments, saponins' foaming property may improve carcass decontamination. In the first experiment of this study, lean beef carcass surfaces were experimentally inoculated with a fecal slurry containing antibiotic-resistant Escherichia coli O157:H7 and Sal- monella Typhimurium.
