In scientific investigations of microwave food
processing, the fluctuating composition of the natural or
biological matter is often problematic. Different contents
of water, sugars and salts result in a shift of dielectric,
heat and mass transport properties and thus a change of
heating or drying curves.
In order to guarantee constant product properties,
a model food was developed imitating real food
properties and showing physical and also microbial
stability over several months. Furthermore, the physical
properties important for microwave modeling have been
determined as functions of temperature and humidity
