Identify one of the drawbacks in the pulsed electric field for food processing
EXPLANATION
Thermal Processing & Commercial Sterilization
- Limitations of Pulsed Electric Field (PEF):
- Pulsed Electric Field (PEF): A non-thermal preservation technology that applies short bursts of high-voltage electric fields ($15-40\text{ kV/cm}$) to cause electroporation and inactivation of microbial cell membranes.
- Major Drawback: The presence of air or gas bubbles in the food liquid causes severe dielectric breakdown, dielectric field distortion, and dangerous electrical arcing (sparking) between the electrodes, scorching the food and damaging equipment.
- Correct Option: Option 1 (Presence of bubbles).
