Abstract: In order develop a new method for the discrimination of the principle components of abalone from different areas, fourier transform infrared(FTIR) spectrometry has been used for the comparison of the characteristic infrared peaks of abalone from three areas. The experiment results show that:the frequency, intensity, and shape of the infrared spectra peaks were different,to a certain extent, among the abalone from different areas, and to identify the abalone origin it provided an effective means.
