Objective

Composition of foods to help determine the dielectric spectra, in particular, added water

 


 

Motivation

During the processing of food, water is addZwei Studenten und eine Tasse Kaffeeed:

  • By cleaning
  • To maintain the nutritive
  • Antioxidant effect
  • Qualiy preservation
  • Downside: Dilution of the food


As from 2001 in the EU mandatory labeling of added water in food.

 


 

Open Coaxial Line as a Probe

  • The probe consists of an open coaxial line, with the reflection coefficient is measured
  • The reflection factor is measured with a network ranging from 200 MHz to 12 GHz
  • So easy, the probe is also a good contact with the test object is very important for testing
  • Even a small air bubble can make a measurement useless
