determination of the dielectric properties of a sample. When a microwave
frequency radiation interacts with the sample, a change in
the rotation of the polarmolecules is produced and dielectric parameters,
which can be related to composition and quality parameters,
can be calculated. Water is the main polar molecule in food and
therefore, the number of water molecules, as well as their relationship
with their environment, determines the dielectric properties
of the food. Microwave spectrometry has been be used to determine
the presence of added water in different pork products
