The following conclusions have been reached, milk has an obvious absorption in the mid-infrared band, and the locations of the absorption peak are consistent with the attributes of molecule functional group analysis and the information from FOSS Company; the effects of the factors on the repeatability are below 3‰; For the quantitative analysis, the method of factorial design is applied to optimize the calibration set. The outliers are determined considering the residual variance distribution. The correlations are 0.990 and 0.986 for fat and protein, respectively. The Root Mean of Square Error of Prediction is 0.121 and 0.111 for fat and protein, respectively. With the application of the methods of wavelengths selection, the numbers of wavelength is decreased greatly from 3301 to 100. The speed is accelerated and the accuracy of the calibration is improved to some extent.
