composition monitor


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

During the processing of food, water is added:
- 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
