“…() provided interesting and current information on the multiplicity of analytical methods that can be used to identify adulteration in foods. Such methods include vibrational spectroscopy (dos Santos et al., ), including near‐infrared, NIRS (Chiesa et al., ), mid‐infrared spectroscopy (Karoui, Downey, & Blecker, ), and Fourier‐transform infrared (FTIR; Gao, Zhou, Han, Yang, & Liu, ), nuclear magnetic resonance, NMR (Gad & Bouzabata, ; Longobardi et al., ; Spiteri et al., ), mass spectrometry (Wu et al., ), proton transfer reaction mass spectrometry (Granato, Koot, & van Ruth, ), spectrophotometric, potentiometric, and chromatographic methods (Alonso‐Salces, Serra, Reniero, & Heberger, ; Granato, Margraf, Brotzakis, Capuano, & van Ruth, ; Wu et al., ), and other methods (Azcarate, Gil, Smichowski, Savio, & Camiña, ; Bevilacqua et al., ; Dong, Zhao, Hu, Dong, & Tan, ). Such methods provide a robust fingerprint of the test samples and usually generate a large and complex data matrix that, if properly analyzed, can show even slight differences between factors (such as lots, manufacturers, geographical origin, and so on; Peng et al., ).…”
