One of the main directions of dairy cattle breeding is the use of promising milk processing methods that meet the requirements of technical regulations and standards and Sanitary Rules and Norms (SanRaN). The purpose of the experiment is to improve the quality and safety of dairy products by suppressing the development of microorganisms. In the course of conducted studies, it was determined that EMR had a significant effect on protein density and composition of milk. In the experimental sample the bactericidal effect of electromagnetic radiation was observed on yeast-like and microscopic mold fungi. During the study of protein fractions of milk, a difference was revealed in the following parameters: total nitrogen, protein mass fraction, non-protein nitrogen, and urea, as well as whey and casein protein content. In the experimental milk sample, the content of total nitrogen was significantly higher as compared with the control sample. Basing on the obtained data, it can be concluded that milk without EMR treatment features the decreased amount of milk protein due to the development of milk microorganisms, which used it as power sources. The organoleptic evaluation has shown that during the electromagnetic treatment of raw milk no negative changes in consistency, odor and taste were noted.
