Intermediate infrared rapid batch detection method for alpha s1-casein in milk

The invention belongs to the field of dairy cow performance determination and milk quality detection, and discloses an intermediate infrared rapid batch detection method for alpha s1-casein in milk. According to the intermediate infrared rapid batch detection method, on the basis of data obtained by an infrared spectrometer in original Fourier transform, wave bands with much noise and less effective information are removed, manual dimension reduction is carried out, and the intermediate infrared rapid batch detection method for the alpha s1-casein in the milk is finally obtained by preprocessing spectral data through using an SG convolution first-order derivative, extracting intermediate infrared spectral characteristic variables through a competitive adaptive reweighting method, and constructing a regression model by using training set data through a support vector machine regression algorithm. The intermediate infrared rapid batch detection method has the advantages of high identification speed, high precis
