[Identification of soybean varieties by direct determination of FTIR spectrum].
The spectra of cotyledons and outer layer parts of skins of eight kinds of soybeans were determined by FTIR spectrometry with OMNI-sampler directly, fast and accurately. The absorption peaks of the spectra w ere analyzed. Results from the comparison of the spectra showed some differences in the intensity and the shape of absorption peaks of their FTIR spectra, especially in the range of 1800-1200 cm(-1), which mainly reflected the substituent nature of amide I and II of protein. The major differences of spectra in this region might result from the differences in genes. So FTIR spectra could be used for the identification of soybean varieties.
