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
