Innovations such as Pulsed
Electric Field Preservation (PEF - P), High Pressure Thermal Sterilization (HPTS) and
Low Shear Extrusion (LS - Extrusion) could be
applied to industrial food production, however, their current application is still limited.
When an
electric field is
applied, the electrons move from an energetically higher lying potential well to an energetically
lower lying potential well via the quantum mechanical tunneling effect.
