Abstract

Various microbial inhibitor systems were studied for their effectiveness in a semgmoist dog food formulation. The effectiveness was measured as inhibition of the natural contaminants Aspergillus glaucus and Staphylococcus epidermidis and of an inoculated challenge organism, Aspergillus niger. The study was carried out at aw 0.85 and 0.88 and at pH 5.4 and 6.3 giving a total of 108 systems. It was found that very few compounds alone or in combination could prevent growth of all three organisms. The only FDA approved additive that was effective alone was propylene glycol.
