It should be noted that the effect of salt addition on the growth
rate of B. cereus and L. monocytogenes could be clearly discerned
from the data. The growth rate of both strains was significantly
reduced by the addition of 3% salt to the zucchini pureé. Therefore,
it is clear that the system can provide useful information in
studying growth and inhibition in real food matrices but highlight
the need for larger data sets to demonstrate the suitability for PM
data collection.
