| Popis: | The shelf life of sour milk dessert has been substantiated based on the results of this study into the indicators of active acidity, water activity, enthalpy, and organoleptic properties. In addition, the content analysis of lactic acid bacteria and microbiological indicators in the finished product during storage was performed. It was found that the introduction of sublimated fruits together with whey protein concentrate reduces the water activity index from 0.984 to 0.972 by increasing the concentration of solids and product viscosity. The active acidity indicator acts in combination with the water activity on the shelf life of food products. Active acidity during the study period was in the range of 5.4‒4.2 pH units. The biological and physiological value of the fermented milk product will increase due to the use of a starter culture containing microorganisms of bifidobacteria and lactobacilli, which include Streptococcus thermophilus, Lactobacillus delbrueckii ssp. Bulgaricus, Lactobacillus acidophilus, Bifidobacterium lactis, Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus paracasei, Bifidobacterium infantis. When storing sour milk dessert for more than 3days, the number of bacteria came down and was 1.0×108CFU/g on day 9, which meets the regulatory requirements. Based on the results of microbiological indicators, the shelf life of the sour milk dessert was established, which should not exceed 5 days at a temperature of 4±2°С. The development and improvement of sour milk desserts using secondary milk raw materials is a promising area of scientific research. This would allow the development of waste-free technologies with the maximum use of useful components that are included in the secondary milk raw materials |
