A device for determining the fat content of milk has been created in Russia 

Russian scientists have announced the creation of a portable analyzer device that allows you to quickly determine the fat content of milk in almost any conditions, without resorting to laboratory equipment, Techkult reports. The basis of this system consists of three LEDs of the most common colors, thanks to which it becomes possible to determine the percentage of fat content.
As mentioned, the operation of the device has "other physical principles" in terms of milk fat measurement. we are talking about the effect of light scattering, which is caused by the colloidal particles of milk. In this case, blue, green and red LEDs irradiate the sample, after which the scattered light is recorded by a special detector.
Particles of different sizes with different wavelengths give correspondingly different scattering, and despite the fact that the actual intensity of these indicators is low, the trained model quite accurately determines the fat content of milk in a sample based on only three parameters obtained from the LEDs, each blue, green and red.
It should be noted here that now in industrial production milk fat content is determined either by direct sample separation or by analysis in the infrared region. These are quite expensive methods that require special equipment, mostly foreign.
Thus, the transition from laboratory tests to affordable portable systems will open new opportunities for monitoring the quality of milk and milk-based products. Furthermore, such sensors can even be integrated into milking machines, milk trucks as well as directly on production lines.
