Ziel’s process uses electromagnetic energy waves to energize molecules in commodities and pests.
Applied energy waves are absorbed by water and other polar molecules where they induce thermal effects that lead to pasteurization and disinfestation.
Contrary to conventional thermal processing, radio frequency (RF) energy heats volumetrically and is able to penetrate packaging materials thus providing opportunities for effective sanitation. RF is thus a physical, chemical-free (residue free, non-additive) new process applicable to conventional and organic commodities.
Radiofrequency (RF) Process
- The RF process exposes the dipoles (a molecule with separated positive and negative charges) to an oscillating electric field that causes the dipole to continually align itself with the field.
- Dipoles rotate and create friction. With common foods, the dipole that’s easiest to rotate is free (unbound) water.
- Other weaker or induced dipoles like fatty acids, amino acids, proteins, phospholipids, etc., also create friction, but with restricted rotations.
- Ionic conduction (ion displacement) creates small electric currents and resistance heating.
- Polarization of cells alters cells’ metabolism.
