In this thesis,classical least square(CLS)regression was applied in the attenuate total reflection mid-infrared(ATR-MIR)spectra data processing of lime in wheat flour to develop the corrected peak height model of the raw spectra,the corrected peak area model of the raw spectra,the corrected peak height model of the 2nd derivative spectra and the corrected peak area model of the 2nd derivative spectra *** result indicated that the correlation coefficients of the four models mentioned above are 0.9648,0.9696,-0.9646and-0.9599 respectively.F-test result indicated that a very remarkable correlation exists between the estimated and specified values of the calibration set and external validation *** detection limits of the four models mentioned above are 3.51%,3.21%,3.51%and 3.69%respectively,which can fulfill the demand for the rapid quality safe screening of wheat flour in the *** method,to some extent,can provide some references for not only the design and manufacturing of the special MIR instrument for the quality safe control of wheat flour in the market but also the quantitative determination of banned additives in wheat flour.

Shucking is one of the necessary parts for the deep process of peanut,and has great impact on the quality of peanut *** the shucking force as the evaluation indicator,the effects of mechanical and physical characteristics,which include the loading orientation,loading rate,moisture content,partical size and the number of peanut kernel,on peanut shucking were investigated by means of single factor *** results show that:1)the loading orientation and moisture content affect the shucking force significantly,and the needed force is the minimum when the peanut is vertically placed and *** the decrease of moisture content,the needed force decreases gradually.2)the loading rate,particle size and the number of peanut kernel have no great effect on the shucking force,but the deformation and maximum shucking force vary with the loading ***,the needed force increases with the number of peanut *** research results can provide some reference for the designment of peanut sheller and selection of the technique parameters.
