Control Measure | Procedure | Treatment/Effect on B. cereus | Reference |
---|---|---|---|
Control initial microbial load | Use of sodium hypochlorite and weak acids on equipment | 100 ppm sodium hypochlorite Weak acids at 30–40 °C for 20–30 min |
[34] |
Inactivation | Heat treatment | D-value (90 °C) 3.99–45 min 70 °C for 12 s, 6 log reduction (vegetative cells) 105 °C 36 s, 6 log reduction (spores) |
[40,62] |
High Hydrostatic Pressure (HPP) | More than 1000 MPa | [63] | |
Combined treatments | Mild heat and High Hydrostatic Pressure, between 100 and 600 MPa at 30 and 60 °C, 6 log inactivation | [64,65] | |
Olive powder 2.5% and High Hydrostatic Pressure 500 MPa had additive effect | [66] | ||
