Themain contents of this dissertation are as follows:(1) The quality analytiedal results of chitosan are as follows: water for 15.205%;degree of deacetylation 92.671%; the weight average relative molecular weight ofchitosan 195900; the viscosity average relative molecular weight of chitosan 194100;and the decomposing temperature 298℃. The infrared ray IR spectra of chitosanshows that the feature-absorbing band of chitosan amido was 1601cm~(-1), that ofβ-indican bond was 986cm~(-1). The results of the X-ray diffraction of chitosan indicatesthat its degree of deacetylation and degree of crystal are both big.

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.
