Topicality. In Ukrainian society there is concern about the quality of dairy products produced by domestic producers. Dairy production is the most necessary in the diet of a human, especially at the child�s age. We cannot image the child diet without milk and dairy products. As the infant�s body is much more fragile and vulnerable to the quality and safety of the food, which he consumes, so the requirements to the quality and safety of dairy products need to be tightened, and the requirements must be increased. And it is precisely such the requirements that should apply to the development of economic entities that have the direct relation to the production, , maintenance and processes of milk processing. Aim and tasks. The purpose of the article is to analyze and estimate the condition of the commodity market in the link of the dairy product chain, the sanitary state of milk being milked, volumes of milk supply to the processing enterprises, production and distribution of the dairy products by sales channel, problems and possibilities of providing rational needs and the level of consumption of milk and dairy products by the population. Research results. Carried out complex analysis of the state of dairy industry and the raw material market in the link of the dairy logistics chain, the sanitary state of fresh milk, the volumes of milk supply to the extra grade processing enterprises, production and distribution of dairy products by sales channels. Conclusion. The condition of dairy market and enterprises shows, that adopting legislative and regulatory measures and norms synchronized with European ones will not produce the expected results, unless supported them by real investment projects, aimed at developing the market sectors, and, first of all, the raw milk sector, which produces milk. The strategy for the development of the milk market should be based on the development of large-scale milk commodity farms, equipped with all the necessary infrastructure: feed-storage shops, veterinary services, milking machines and cooling, and most importantly quality laboratories.

Milk is a part of many food products. In the expert assessment of raw material quality, primary attention should be paid to its microbiological safety, since poisoning with dairy products is a common cause of gastrointestinal tract diseases. The experiment was conducted on the basis of the Educational and Production Livestock Complex of the FSBEI HE RSAU – MAA n.a. K.A. Timiryazev (city of Moscow). The purpose of the study is to optimize the quality indicators of raw milk and dairy products. A method of raw milk processing has been studied to reduce the number of potentially dangerous microorganisms in the products produced from it. The fact of changes in organoleptic and physico-chemical parameters under the influence of an electromagnetic field is established; the quantitative and qualitative composition of milk and yogurt microorganisms is assessed. The article describes the issues of ensuring the microbiological safety of raw milk and suggests a method for optimizing the sanitary and hygienic indicators of dairy products, in accordance with the current requirements of regulatory documents.

The purpose of the study was a comparative assessment of the actual diet of preschoolers, taking into account changes in the requirements of sanitary legislation on the organization of public catering. Materials and methods. Nutrition was assessed based on a study of the menu-layouts of two-week implemented menus in 4 preschool organizations. The analysis of children’s diets’ nutritional and biological value was carried out according to the leading indices of normative documents and legislative acts. A comparative characteristic of the actual food set was carried out, taking into account the changes in the requirements, the sanitary and epidemiological rules, and norms of SanPiN 2.3 / 2.4.3590-20 that had come into effect again. Results. The structure of the food set sold to children in the preschool organization was irrational. The optimal consumption (from 94 to 104% of the norm) of primary food products (meat, poultry, milk and dairy products, cottage cheese, sour cream, eggs) was established. The disadvantage of the menus under analysis was the deficit in the food assortment of rye bread, fish, fruit, leftover pasta, sugar, confectionery, and the presence of products excluded from the new food set (sausages). The nutritional and energy value of children’s diets was sufficient compared to the norms of physiological needs. However, there was an imbalance in both macro and micronutrients, especially calcium, phosphorus, and magnesium. Conclusion. According to the menu-layouts in children’s institutions, evaluation of children’s nutrition showed that they did not comply with both the previously existing and newly introduced regulatory requirements for indices of food supply and the chemical composition of rations. The needs of the recently entered sanitary rules and norms for feeding organizations were not considered when drawing up the menu in institutions. Revision of the food set requires making adjustments to the technological charts for baby nutrition and the elaboration of guidelines for developing menus in new conditions.

The share of products with higher added value is constantly decreasing in Slovakia's agri-food exports and the share of basic agricultural raw materials with low added value is increasing. Commercial retail chains sell especially products without added value. On the other side, products that have undergone a processing are imported from abroad. According to the latest survey of the Slovak Food Chamber of Agriculture in 2016, the share of Slovak products on retailers and retail chains is only 39.91%, with 38.9% in 2015 and 2014.with increase of only 1%. Most of the agri-food products produced in Slovakia are at most represented in commodities: eggs, milk, honey and at least in the following categories: processed vegetables, packaged meat and processed fruit. The main objective of presented paper is to show, that Slovak farmers rather sell raw milk instead of selling added value processed products. A big difference can be found between milk and dairy products, where up to 20% is the difference in the representation of these products in the commercial chains. This fact means, that the Slovak farmers produce enough milk, but it is convenient for them to sell milk as a raw material instead of processing it in their own direction and selling the processed products. Raw milk is exported abroad and then comes back to the Slovak market with an added value as processed product. The survey, which was carried out on all trade chains, showed that the share of Slovak milk in the chain is 63%. An important finding is also the presence of individual dairy products that are produced in Slovakia. The result of the survey showed that the largest share of Slovak dairy products in the domestic market is 51% cottage cheese and sweet / sour cream 55% lowest ripening cheese 40%and processed cheese and cheese spread 43%.

Contrary to the safe practices of milk pasteurization or sterilization, which effectively reduce foodborne outbreaks incidence associated with raw milk and dairy products use, outbreaks caused by such products continue to occur. Despite this fact, a worldwide movement advocating for the rights of raw milk and cheese selling and consumption, due to their specific nutritive characteristics, has strengthened significantly in recent years. Traditional agricultural manufacturers from Serbia still sell products related to thermally unprocessed milk, such as cottage cheese and raw cream. In AP Vojvodina during the period of 1981-2010 a total of 179 foodborne outbreaks were reported, where the incriminated cause of the outbreak were milk or diary. In 126 (70.39%) outbreaks, totaling 2276 sick individuals and one casualty, it was confirmed that the incriminated food was from the group of dairy products. In 48 instances (26.82%), bacteriological tests confirmed that milk and dairy products were excluded as the outbreak causes, while in another 5 (2.79%) outbreaks, microbiological analysis of food failed to confirm any relation to the actual epidemiological instances. In some cases, bacteriological testing of incriminated foods was not possible. In the cases of outbreaks associated with the consumption of milk and dairy products, traditional raw milk products were cited as being used. Consumption of unpasteurized milk and cheese represents public health threat. National and international rules ensuring use of safe products for human consumption have to set rules of trade of thermally processed milk and products on the market.

Milk And Dairy Products

Milk and dairy products are an excellent environment for the development of microorganisms that can cause various defects in the products and in some cases lead to human disease. Under the action of bacteria, yeast, molds, if the rules of procurement are not observed, transportation, storage and sale of dairy products deteriorate rapidly, lose nutritional value, become dangerous for consumption. The purpose of the research was the monitoring of quality of dairy products sold in the trade network of Dnipro according to the sanitary-microbiological indicators. Material and methods. We analyzed 79 samples of milk and dairy products of different trade mark. 56 (64,5%) samples were not standard indexes from which 10 samples of pasteurized milk, 9 samples of yogurt, 6 samples of kefir, 8 samples of sweet-cream butter, 7 samples of cottage cheese, 6 samples of sour cream and 5 samples fermented baked milk. Results and discussion. The obtained results showed that 19 samples of dairy products contained less viable bacteria, than it was indicated according to sanitary and microbiological indexes. There was the greatest number of nonstandard products among samples of yogurt (6) and cottage cheese (4). The study showed that out of 56 analyzed dairy products 13 contained yeast in an amount that exceeds the standard rates. The largest number of non-standard samples (5) was found in yogurt. In 12 samples the maximum number of molds was exceeded. The highest number of molds contaminated product samples was found among cottage cheese (4), kefir (3) and butter (3). In the presence of sanitary-indicative microorganisms we did not meet the requirements of the normative indicators of 35 samples of dairy products, which was 44.3% of the total number of analyzed samples. Escherichia coli bacteria were found in samples of all types of dairy products. The most contaminated were samples of milk (6 samples), kefir (6 samples) and yogurt (5 samples). Conclusion. Out of 7 types studied most dairy products contaminated by all indicators were yoghurt and cottage cheese. Staphylicoccus aureus was detected in 2 samples of lactic acid products. Pathogenic bacteria, including representatives of the genus Salmonella and Listeria monocytogenes, were not found in none of 79 samples of seven types of dairy products

Liquid Milk

AbstractMilk and dairy products are major components of the human diet in Western countries, providing about 30% of dietary proteins and lipids. The current annual production of milk is 560 x 106 tonnes, of which 85, 11, 2 and 2% are bovine, buffalo, caprine and ovine, respectively. Although some raw milk is still consumed, the vast majority of milk is processed to at least some extent. Liquid milk is a major food item in all developed dairying countries, representing 30% of total milk production. The remainder is processed into one of several thousand products, making dairy products the most diverse and flexible group of food products. The flexibility of milk as a raw material resides in the chemical and physico-chemical properties of its constituents, many of which are unique. The principal constituents of milk can be modified by enzymatic, chemical and/or physical methods, permitting the production of new products. However, the concentrations and properties of milk constituents are variable and hence the processability of milk and the properties of dairy products are inconsistent, although much of this variability can be eliminated by employing modern technology, which exploits certain features of milk constituents. Today, most milk is processed in very large, highly mechanised and automated factories, where consistency in processing properties is essential. The resulting products are distributed through large wholesale and retail outlets, where consistency is, again, paramount. Finally, today's consumers expect consistency. The consistency expected by the processor, distributor and consumer can be achieved only if the properties of milk constituents are understood at the molecular level.This communication will describe:The chemical and physico-chemical properties of the principal constituents of milk, i.e. lactose, lipids, proteins and salts,Variations in milk composition and in the properties of its constituents and the influence of dairy husbandry practices thereon,Exploitation and significance of the chemical and physico-chemical properties of milk constituents in the production and properties of the principal groups of dairy foods, i.e. liquid milk products, cheese, butter, fermented milks, functional milk proteins and lactose.Process modifications which may be used to overcome variations in the properties of milk constituents.
