Comparison of observed PEF inactivation and predicted heat inactivation of L. innocua NCTC 11289 at different temperatures after treatment for 13.2 sa
| Temp (°C) | PEF inactivation (log) | Heat inactivation (log) |
|---|---|---|
| 55 | ≥6 | <0.05 |
| 57.5 | ≥6 | 0.2 |
| 60 | ≥6 | 0.4 |
| 62.5 | ≥6 | 0.9 |
The predicted values were calculated by using the D values and z value in Table 1. Both the PEF treatment and the heat treatment were performed in a 10 mM Na2HPO4 · 2H2O-NaH2PO4 · 2H2O solution (pH 4.0; 0.2 S/m at 25°C).
