FIELD: microbiology.
SUBSTANCE: invention relates to sanitary microbiology and, in particular, to quality control method of fermented milk products. Method includes analyzing for the presence of coliform bacteria. Quality control method of quality of fermented milk products involves sampling, preparation of nutrient medium containing whey, yeast autolysate, glucose, 70 % acetic acid, agar-agar and cabbage broth for a given ratio of components. Sowing samples of nutrient medium. Placed in a thermostat at a temperature of 37 °C and kept 24 h followed by visual determination of the colonies of coliform bacteria in fermented milk products. In their presence, dairy products are classified as substandard.
EFFECT: invention allows to improve the quality control of manufactured fermented milk products.
