What intensity of pulsed electric field is used for food preservation?

What intensity of pulsed electric field is used for food preservation? Correct Answer 10-80 kV/cm

Pulsed electric field is also called High Electric Field Pulses (HELP). It is the application of very high field strength for a very short time to foods placed between electrodes. It uses short electric field pulses to preserve food. It works in intensity of 10-80 kV/cm with duration of micro to milliseconds.
