Introduction. The article presents data on the role of milk and dairy products, including fermented milk products, in the human diet and reflects their important role in providing the body with proteins having a high essential amino acid content. In addition to all health benefits of milk, fermented dairy products have dietary and medicinal properties while their digestibility is higher than that of milk. Objective. To demonstrate the role of fermented milk products in human nutrition and benefits of fermented milk products enriched with probiotic microorganisms for preventive nutrition in the microbiocenosis of the gastrointestinal tract. Materials and methods. The article presents an analytical review of literary sources on the role of milk and dairy products, including fermented milk products, in human nutrition and provides information on the per capita production and consumption of milk and dairy products in the Russian Federation. It also addresses the problem of dysbiosis since fermented dairy technology can pose a serious microbiological risk related to favorable conditions for the growth of extraneous microorganisms coming from raw materials, starter cultures, and equipment during the production process. The absence of stringent quality standards for fermented milk products contributes to manufacturing of various counterfeit foods. Results. The article outlines the main provisions of the expert hygienic assessment of specialized food products for preventive nutrition for the purpose of their state registration on the example of fermented milk bioproducts, defines criteria for assessing the quality and safety of specialized products for dietary nutrition and requirements for technical documentation on these products, and provides the list of necessary documents for expert examination of hygiene and safety of specialized products for therapeutic and preventive nutrition. Conclusion. The permission to use novel fermented milk products as preventive nutrition foods shall be based on results of предassessing their compliance with the requirements of technical regulations of the Customs Union and the Eurasian Economic Union on the quality and safety of products and their raw materials, packaging and labeling.

Abstract Introduction Q fever in dairy cattle has been investigated in Latvia since 2012. In 2015, 10.7% of farms tested positive for the DNA of C. burnetii, its aetiological agent, in bulk tank milk. The presence of C. burnetii DNA and infectious bacteria in dairy products has been assessed in several countries, and because Latvian milk may contain them, parallel assessment in this country is recommended. Accordingly, the present study tested shop and farm retail dairy products from Latvia and included foreign products for comparison. Material and Methods Investigation was carried out of 187 samples of a diverse range of dairy products from 41 Latvian milk producers. Twenty-six comparable samples pooled from Estonia, France, Germany, Greece, Italy, Lithuania, the Netherlands, Poland and Spain were also included. The all-countries total number of fermented milk products was 160. Special attention was paid to products that could be more attractive to children because of their added chocolate, cacao, berry and fruit content. DNA was extracted and amplification of C. burnetii IS1111 was performed using a commercial PCR kit. Results Overall positivity was 60.56%. Domestic products were positive more often (60.96%) than foreign ones (57.69%). Only 26.67% of unpasteurised Latvian cow’s milk samples were positive whereas 76.47% of pasteurised equivalents and 63.13% of fermented milk products were. Sweetened and fruit-containing samples were 71.43% positive. Conclusion The shedding of C. burnetii via milk should be monitored and only milk from healthy animals allowed for sale for direct human consumption without pasteurisation. Raw milk quality and the effectiveness of industrial heat treatment and pasteurisation methods in Latvia and other countries should be carefully assessed to ensure adequate consumer health protection.

In this study, the effects of kombucha inoculum as non-conventional starter culture on fatty acids composition of fermented milk, compared to a commercial probiotic (ABT-7) and yoghurt (YF-L812) starter cultures, during 21 days of storage was investigated. Fatty acids composition was determined by gas chromatography-mass spectrometry after the previous extraction of lipids and derivatization. The atherogenic (AI) and thrombogenic (TI) indices determined on the basis of fatty acids composition have been used for evaluation of the nutritive lipid quality of the fermented dairy products. The most significant levels of fatty acids in fermented milk products were palmitic, followed by oleic, stearic and myristic fatty acids. Fermented milk products were characterized by low atherogenic (2.14-2.39) and thrombogenic (2.91-3.18) indices, suggesting their consumption could have a favorable effect on human health. The AI and TI were comparable during the storage of fermented milk samples. Starter culture did not affect the health-related fatty acid composition of fermented milk products during storage.

The aim of the study was to determine the effect of marinating with fermented milk products (buttermilk and sour milk) on the physical characteristics, microbiological quality, and sensory acceptability of Rhode Island Red (RIR) hen meat after the first year of laying use. The hen breast meat was marinated with fermented dairy products, buttermilk and sour milk, by the immersion method for 12 h at 4 °C. The assessed features included the quality of raw and roasted marinated and non-marinated meat in terms of physical characteristics (marinade absorption, water absorption, pH, L*, a*, b* colour, shear strength, texture profile analysis (TPA) test), microbiological parameters, and sensory characteristics. Bacteria were identified by the mass spectrometry method (MALDI-TOF MS Biotyper). Marinating meat with fermented dairy products lightened the colour, decreased the value of shear force, reduced hardness and chewiness, and limited the growth of aerobic bacteria and Pseudomonas spp. Additionally, after heat treatment, the number of identified aerobic bacteria families in the marinated in buttermilk and marinated in sour milk groups was smaller than in the non-marinated muscle group. The sensory evaluation showed a beneficial effect of marinating with buttermilk and sour milk on the tenderness, juiciness, and colour of roasted meat.

Grain-based foods play an essential role in human nutrition. Cereal-based products contain soluble and insoluble dietary fiber, which, by reducing cholesterol levels, reduce the risk of cardiovascular diseases, as well as stabilize digestive functions, preventing diseases of the gastrointestinal tract. Grain products supply the human body not only with energy, but also with protein – by 30-40%, b vitamins by 50-60%, and vitamin E by 80 %. In preliminary studies, 4 types of extruded grain bases were identified from buckwheat, millet, lentils and chickpeas, defined as the basis for fermented dairy products. 20 experiments were carried out in each of the variants using extruded grain bases from buckwheat, millet, lentils and chickpeas with two variants of the milk base – milk with a fat content of 2.5 and 3.2 %. mathematical models of the response function dependences on the selected factors were Obtained, which allowed determining the optimal ratio of ingredients for each of the considered variants. Developed formulation of two dairy products with grain-based extruded from millet based on milk with 2.5% fat and extruded grain-based chickpea based on dairy products with fat content of 3.2%. According to physical and chemical parameters, all samples of fermented milk products met the requirements regulatory documents.

Milk And Dairy Products

Milk and dairy products present an important source of essential nutrients which should be a part of human beings nutrition. While the recommended consumption of milk and dairy products is set at the level of 220 kg/person/year, the current studies show that Slovaks consume only 160 kg/person/year. One of the possibilities how to reverse this negative trend is to raise the Slovak consumers awareness of the positive impacts of yoghurts and fermented milk products on their health, as well as to made from them a so‑called trendy food. The aim of the presented paper was to determine the consumer behaviour in the purchase of yoghurts and fermented milk products produced in Slovak Republic. As the research methods were used the methods of survey and structured questionnaire consisting of 16 closed and 1 opened question (total number of respondents was 1,131 randomly selected respondents from all regions of the Slovak Republic). For a deeper analysis of the obtained results, there were set out six assumptions and ten hypotheses, which were tested with the use of Pearson’s chi‑square test, Fisher’s exact test, Cramer’s contingency coefficient and Phi coefficient. The results of the presented paper show, that despite the fact that almost 77 % of respondents said that they prefer in their purchase yoghurts and fermented milk products produced in the Slovak Republic, only 26.4 % of respondents said that they prefer the local producers of these products; exactly 44 % of respondents said that they always look for the information about the content of fat in the yoghurt they buy; more than 33 % said that they buy yoghurts and fermented milk products marked with the Quality Label “Značka kvality SK”; more than 62 % of respondents said that they purchase yoghurts and fermented milk products produced by ecological farming exclusively and rather and exactly 60.1 % of respondents said they prefer the plastic packages of yoghurts and fermented milk products. Up to the question aimed at determining which flavour consumers actually miss on the market, we have to conclude that these flavours are mostly kiwi, muesli with cranberries, chocolate with mint, coconut and banana.

Exopolysaccharides Production

Currently, much attention is being paid for improving the texture of food by screening the new exopolysaccharides (EPS) producing strains. The aim of the present work was to isolate EPS producing Lactic acid bacteria (LAB) strains from raw milk and milk products samples. Total of thirty eight dahi, lassi and raw milk samples were collected from different villages and towns of Karnal and Delhi District. The samples were plated on milk agar and colonies showing ropy polysaccharides production were subjected to biochemical test. After molecular identification 2 were found as <italic>S. thermophilus</italic>, 2 were <italic>Lb. rhamnosus</italic> and 2 were confirmed as <italic>Lb. fermentum</italic>. Two <italic>S. thermophilus</italic> strains (PD7 and PD11) and <italic>Lb. fermentum</italic> strains (AL6 and AD3) showed better curdling pattern, acidity, exopolysaccharides production, and sensory properties. These cultures can be used for manufacture of indigenous fermented milk products.

Milk and milk products play a vital role in human nutrition all over the world. In addition to being a nutritious food for humans, milk and milk products provide a favorable environment for the growth of spoilage and pathogenic microorganisms. Thus, this paper aims to review the microbial properties of milk and fermented milk products produced in different parts of Ethiopia. Microbial contamination may generally occur from within the udder, exterior to the udder, from the surface of milk handling and storage equipment and the traditional practice. The status of the cleanliness of the milkers could be the primary sources of the initial milk contamination. The reviewed dairy products are Milk, Ergo (naturally fermented milk), Kibe (traditional butter), Arera (defatted sour milk) and Ayib (Ethiopian cottage cheese). The existing microbial quality of dairy products produced in the rural part of Ethiopia was poor and did not meet the acceptable quality requirements. The problem was compounded from limited knowledge of the hygienic production, processing and handling of dairy products coupled with inadequate dairy processing infrastructures. Strict hygienic control measures along the value chain to improve the hygienic conditions of milk starting from production to consumption are necessary to provide safe products to the consumer.
