A shift in amplitude for the S11 (reflection) and the S21 (transmission) signal was observed between different weight loss groups at
given frequencies. This shift was related to results from chemical analyses of water activity, salt content and water content. The correlation
with the microwave measurements was ranging from 0.76 to 0.98, depending on the type of parameters measured and spectra analysed.
The results presented here indicate that microwave measurements
might be a promising technique for the determination of different
quality parameters for the process control of dry-cured hams. Further
studies should include investigation of microwave measurements for
other types of dry-cured meat.
