[0013] See figure 1 , The present invention is implemented as follows:
[0014] 1) Use the Fourier transform near-infrared spectrometer to collect the near-infrared spectrum data of all the samples to be tested, obtain the original near-infrared spectrum data of the samples to be tested, and preprocess the spectrum data to eliminate factors such as spectral shift or baseline change The impact on the performance of the built model ensures a good correlation between the spectral data and the quality indicators of the sample to be tested. At present, the commonly used spectral preprocessing methods include standard normal variable transformation, mean centering, first-order derivative, and second-order derivative. Then, physical and chemical analysis methods are used to determine the concentration values of the components to be tested for all samples to be tested, and based on the concentration values of the components to be tested, the pre-processed raw near-infrared spectro...
