ABSTRACT
During this study quality and declared health features of probiotic yogurt milk were assessed. Using the methods of statistical analysis a tool was developed allowing verification of formulated statistical hypotheses. It was established that no statistically significant differences were present in the assessment of the number of microorganisms dependent on the dilutions applied. It was shown that the number of live bacteria in the product during storage decreases and that those changes are statistically significant. It was determined that the average number of live probiotic bacteria in the product in all samples during storage was significantly higher than declared by the producer m value and it indicated appropriate health quality of the tested product.
