  • Synergistic antimicrobial compositions
    Patent number: 5250299
    Abstract: The invention discloses an antimicrobial composition composed of a hypothiocyanate generating system adjusted to a pH between about 1.5 and about 5 with a di or tricarboxylic acid. This composition provides synergistically improved antimicrobial action. With the addition of the organic acid, the antimicrobial composition provides effective cidal activity against Gram negative microorganisms in 20 minutes or less. The composition is particularly effective against Salmonella and may be used to provide greater than 6 logs reduction in viable cell count.

  • Synergistic antimicrobial compositions
    Patent number: 5043176
    Abstract: The invention discloses an antimicrobial composition composed of an antimicrobial polypeptide and a hypothiocyanate component. Synergistic activity is seen when the composition is applied at between about 30 and 40 degrees Centigrade at a pH between about 3 and about 5. The composition is useful against gram negative bacteria such as Salmonella. A preferred composition is nisin, lactoperoxidase, thiocyanate and hydrogen peroxide. Such a composition is capable of reducing the viable cell count of Salmonella by greater than 6 logs in 10 to 20 minutes.
