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.
