The new product contains an antioxidant complex and a herbal ingredient that expands the product range.

This article describes the effect of pre- and probiotics on the condition of intestinal microflora for newborn calves. It has been established that in the intestines of calves, in addition to lactic and bifidobacteria, conditionally pathogenic bacteria such as E. coli, staphylococcus and streptococcus are contained. When taking pre- and probiotics in the experimental groups of animals, a decrease in the content of conditionally pathogenic microflora was observed with a dynamic increase in obligate, which indicates a positive effect on the formation of intestinal microbiocenosis during the milk period.

This article describes the effect of pre- and probiotics on the digestibility of feed by newborn calves. The calves of the experimental groups had a high growth energy, which was reflected in the absolute growth rates and their development.

This article describes the factors that adversely affect the development of the body of young animals and contribute to reduce their productivity. One of the ways to solve this problem is the use of probiotic preparations, in this case Vetom 1.1. Research methods are presented, an analysis of the data obtained is made, according to which a conclusion is drawn about the high effectiveness of the use of probiotic Vetom 1.1 in swine production

The article presents the rationale for the use of fermented milk products containing probiotics and prebiotics for the prevention of diseases of the gastrointestinal tract. A method for preparing a functional fermented milk drink with prebiotics that helps normalize the intestinal microflora is also presented. The urgency is due to the wide spread gastrointestinal diseases among the population of the Republic of Kazakhstan, due to lack of nutrients essential for development of normal intestinal flora, and also with the instability of some types of probiotics, which reduces the efficiency of their use.

This article discusses the idea of developing a functional product that exhibits biologically active, bifidogenic properties and a strong antioxidant effect. The authors propose the formulation of sea buckthorn marmalade with the addition of immobilized probiotics. The jelly-fruit marmalade formulation is used as a control sample; apple puree is replaced with sea buckthorn concentrate, sugar and molasses with fructose. In experimental samples, various methods of introducing probiotics are used and their viability in the finished product is further evaluated. According to the organoleptic characteristics, the samples have a pleasant taste, smell, original color, gelatinous consistency. The best viability was shown by microorgan isms immobilized by incorporation into the gel.

This article discusses the current data on the biochemical properties of bacteria of the genus Lactobacillus and their use in industry, particularly in dairy production and biotechnology. Microorganisms of the genus Lactobacillus have antagonistic activity against pathogenic microorganisms and perform an immunomodulatory function. The positive effect of lactobacilli on human health explains their active use in probiotics. The positive effects of normal intestinal microflora and probiotics are mainly due to bifidobacteria and lactobacilli. In probiotic therapy, various types of bacteria of the genus Lactobacillus are used, such as: L. acidophilus, L. rhamnosus, L. plantarum, L. fermentum, L. delbrueckii subsp. bulgaricus, L. casei, L. paracasei. In recent years, the biotechnology of probiotics has been intensively developing - drugs used for the correction and prevention of microecological disorders in the gastrointestinal tract of humans and animals. An urgent issue is obtaining new data on the biological properties of lactobacilli, creating new probiotic preparations based on them using modified approaches to cultivation. The results of determining the species L. acidophilus L. casei, L. rhamnosus, L. paracasei, obtained by the classical biochemical identification method based on saccharolytic activity, complicating species identification, are comparable to the molecular genetic method. In the case of L. casei, L. rhamnosus, L. paracasei, it is necessary to carry out modern identification methods based on the polymerase chain reaction, since their biochemical properties are similar, which makes it difficult to carry out species identification. The molecular genetic method is a valuable addition to the intergeneric and species identification of lactobacilli, given the variability of the classical biochemical method.

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.
