In this study, the combined effectiveness of pressures of 137.9-344.7 MPa, temperatures of 25-50 degrees C and exposure times of 5-15 min on Listeria viability in peptone solution is examined. The results showed that under the innocua study conditions only the combination of 344.7 MPa, 50 degrees C and 9.1 min can reduce the viability of this species by 7 logs, with a z value of 173.1 MPa.
