Non Thermal Preservation of Food – Oscillating Magnetic Field (OMF)

Oscillating magnetic field (OMF) is generated with electromagnet of alternating current. The intensity varies periodically according to frequency and type of wave in the magnet. OMF is applied in the form of constant amplitude or decaying amplitude sinusoidal wave. The magnetic field may be homogenous or heterogeneous. In homogenous field, field intensity (B) is uniform in the area enclosed by the magnetic field coil. In heterogeneous field, field intensity (B) is non – uniform with the intensities decreasing as distances from the center of the coil increases. Read more
