| Abstract: | Based on the existing spectral data, the spectral information of wheat flour was selected using the Rarnan spectroscopy and near infrared spectroscopy combined with the least square method. The best spectral preprocessing method was selected and the quantitative analysis models of moisture, ash, and glu- ten were established. Moreover, the feasibility of models was verified. The results showed that the model established by the near infrared spectroscopy was better than that of the Raman spectroscopy. |
