title: Inhibition of foodborne pathogens by pomegranate juice.
abstract: Pomegranates have health-promoting benefits because of their polyphenol constituents. Previous studies have demonstrated the antimicrobial activity of aqueous and organic extracts of pomegranate components and by-products. We sought to determine the antimicrobial activity against 40 foodborne pathogens representing eight bacterial species using juice itself. In addition, we sought to determine the synergistic antimicrobial activity between pomegranate juice and other plant products displaying antimicrobial activity. The antimicrobial activity of pomegranate juice was dependent on the test organism, which varied to highly susceptible (four Gram-positive species) to unaffected (Salmonella and Escherichia coli O157:H7). Two Gram-negative species, which were inhibited were Helicobacter pylori and Vibrio parahemolyticus. No synergistic antimicrobial activity was seen between pomegranate and either barberry, oregano, or cranberry. The antimicrobial activity of pomegranate juice is dependent on the test organism and extraction method. The sensitivity of H. pylori suggests that pomegranate juice may be an alternative or supplemental treatment for gastric ulcers caused by this organism.
