Method for determination of fat in milk and milk products that includes interaction of energy (optical, X-ray, acoustic, Etc.) with milk with following registration and analysis of output energy at given frequencies (wavelengths), at that one uses ratio of optical densities of sample that correspond to two characteristic for milk absorption wavelengths, in particular, that for one forms infrared radiation through heating filament, with modulation of infrared radiation with mechanical interrupter; one passes modulated infrared radiation through cuvette with milk sample and registers optical density of sampleD=ln(Inp/І),where Іnp – intensity of infrared radiation passed through sample,and І– intensity of infrared radiation that comes to sample at two wavelengths, one evaluated fat content of milk sample by value D |
