Tuncan, E.U. | Martin, S.E.
The combined effects of salts (NaC1 and KC1) and heat treatment temperature on the thermal destruction of Staphylococcus aureus MF-31 was studied by determining the relationships between the decimal reduction time (D value), temperature and each of three parameters (water activity, osmotic pressure and water binding energy) of the heating menstruum. The results demonstrated that the resistance of S. aureus MF-31 to heat destruction increased as the degree of salt-water association increased. Salts and heat treatment temperature had an interactive effect on heat resistance; however, increasing the heat treatment temperature made the difference caused by salt concentrations become insignificant.
