The pulsing electric field is a very short process…
Pulsed electric field
time
Pulse duration (1-30 us)
Repetition rate (10-100Hz)
Low energy sustainable process
kV
10-100 Hz

… and process temperatures are very low too.
time
Start temperature
10-20oC
Pre-heating up 35-45oC
Temperature increase
5-15oC
Enzyme activity is maintained & Nutritional values are unchanged
Cooling to 4-10oC
40-55oC
80-95oC Classical thermal pasteurization inactivates enzymes and vitamins and changes the fresh taste
