The invention belongs to the technical field of food component detection, and particularly relates to a method for rapidly detecting cow milk components and application. Diluting a cow milk sample, starting a light source module to emit light rays, and enabling the light rays to vertically enter a pool filled with the diluted cow milk sample and be absorbed by cow milk; a photoelectric conversion module is used for acquiring an optical signal after interaction with cow milk, converting the optical signal into an electric signal, and then transmitting the electric signal to an operation module; the operation module processes the electric signals and obtains an initial value of the concentration of each component in combination with the Beer-Lambert law; and inputting the initial value into a weighting function obtained by fitting based on a least square method, and outputting a final value of the concentration of each cow milk component. The infrared focal plane array detector is used as a photoelectric detect
