The article is devoted to comprehensive research and development of the technology of cream supplements for the enrichment of processed cheese products. This article discusses the steady trend towards the use of dairy products with probiotic properties in the diet of modern people. The authors justify the requirements for the chemical composition and properties of a new type of processed cheese product: the mass fraction of dry processed cheese product must be at least 45 wt.%, the amount of probiotic microflora at least 107 CFU/g, to adjust the fatty acid composition of the product, the use of milk fat substitutes. As a result of the research, the composition and technological parameters of the production of a cream Supplement intended for enriching a new processed cheese product were determined. Skimmed milk powder concentrate with a mass fraction of dry substances (48.0±0.5) %was selected to increase protein (nitrogenous substances) in the nutrient medium for microorganisms. To activate the growth of bifidobacteria, the prebiotic No. 1 – lactulose was studied. The main content of the study is the analysis of the effect of increasing the amount of SOM concentrate on the chemical composition of the compositions of experimental products. The bacterial concentrates Bifilact-B and Bifilact-u were selected as the source of probiotic cultures. In fermented products, microbiological indicators were determined: the total number of lactic acid cultures and bifidobacteria. The article analyzes the dynamics of acidity of experimental products fermented with bifilact-B bacterial concentrate and bifilact-u bacterial concentrate. It was found that in experimental products with a high level of acid formation, the growth of bifidobacteria decreases, this is due to the fact that at low pH values, the growth of bifidobacteria slows down, and at a pH below 4.5 – stops. There was a significant increase in the number of bifidobacteria in the presence of a prebiotic – lactulose concentrate. The authors proved that the fermentation process with the formation of a clot in experimental products with bifilact-B bacterial concentrate is completed within 9-10 hours, taking into account the time of compaction of the consistency. In experimental products fermented with bifilact-U bacterial concentrate, the fermentation process ends within 7-8 hours, that is, by (2.0±0.5) hours faster.

Main problem: The unfavorable conditions in which a significant part of the population of our country lives (living in conditions of harmful, stressful, physical, chemical and radiation effects), an imbalance in nutrition dictate the need to create a variety of functional products enriched with pro– and prebiotic factors. In the science of nutrition, a functional direction has been developed - this is nutrition, which provides for the consumption of such products of natural origin, which, when used daily, have a regulating effect on the body as a whole, its certain systems, organs, providing a drug-free positive correction of their function. Compared with traditional types of dairy products with high organoleptic and commodity characteristics, produced on the basis of classical technological techniques, dairy products of the new generation should have increased nutritional and biological value. The article is devoted to the research and development of the technology of a new cottage cheese product - cottage cheese paste produced with the addition of lactulose concentrate and fruit and berry fillers. This article discusses the steady trend towards the use of fermented milk products with functional properties in the diet of modern humans. Purpose: Study and development of technology of thermized cottage cheese paste enriched with prebiotic lactulose and fruit and berry fillers. Methods: Analysis and generalization of theoretical information, organoleptic evaluation, physicochemical methods of analysis, microbiological methods of evaluation of cottage cheese paste, quality control of the finished product. Results and their significance: The positive role of prebiotic substances in the vital activity of the macroorganism was studied. It is not for nothing that academician Andrei Georgievich Khramtsov once called lactulose "a miracle made of milk." Lactulose, being a strong bifidogenic factor, allows stabilizing the microflora of the stomach. Lactulose activates the growth of bifidobacteria, which take root well in the intestine and ferment lactulose to form lactic acid. Lactic acid suppresses the development of pathogenic and putrefactive bacteria. As a result of the conducted studies, it was determined that the cottage cheese paste enriched with lactulose had high quality indicators and retained its consumer properties during the entire storage period. The introduction of lactulose into the recipe of cottage cheese paste does not reduce the nutritional advantages of the finished product.
