Abstract
The effect of added potassium sorbate (0.25%), BHA or BHT (100 or 200 ppm) on growth of Staphylococcus aureus in synthetic media having water activity and pH adjusted to values found in process cheese was studied. Potassium sorbate (0.25%) had no significant effect on growth of S. aureus in this model system at pH 6.0 and 30°C. BHA and BHT (100 and 200 ppm) showed some growth inhibition of S. aureus in a model system. However, both antioxidants were ineffective in preventing (or delaying) growth of various strains of S. aureus in inoculated cheese spread (aw=0.976, pH 6.0) incubated at 30°C.Keywords
