  • the control device can then be set up to additionally calculate the remaining cooking time of the cooking product as a function of the specific permittivity of the cooking product.
  • the probe is inserted into the food.
  • the inserted probe measures the frequency-dependent permittivity (dielectric constant) of the food by means of electrical DC and AC fields.
  • the measured data are compared with stored data in the control device. By heating the food during the measurement, the measurement results can be even clearer.
  • the cooking appliance is for example an oven, a microwave, a steamer or a warming drawer.
