Diversification of dairy products for baby food is a topical trend in the development of the dairy industry. In the process of producing an ultra-heat-treated (UHT) milkshake, milk with a mass fraction of fat 3.5 %, skim milk with a mass fraction of fat 0.5 %, fruit filling "Cherry" and a vitamin premix are used. The technological process of production includes the acceptance of raw materials, assessment of their quality in accordance with regulatory documents; heat treatment of raw milk; preparation of a normalized mixture; adding ingredients. The prepared mixture is sent for deaeration to a flow-through apparatus, then to a homogenizer, where it is subjected to ultra-pasteurization at a temperature of 136 ± 2 °C with a holding time of 4 ± 1 s. The final stage of cocktail production is packaging and intermediate storage. The resulting product was tested in the laboratory for organoleptic and physicochemical indicators. During the experiments, it has been found that the taste, smell, colour, appearance and consistency meet the requirements of state standards. The content of protein, fat, carbohydrates, calcium and titratable acidity are within acceptable values; the content of vitamins A, D, E, B is higher than the minimum values. The research results on safety indicators meet the requirements of technical regulations. Antibiotics, GMO-derived materials and preservatives are not found in the product. The energy value of the baby milk shake is 63.7 kcal (266.6 kJ/100 g of product).

The seasonal variability of the physicochemical parameters of milk of both ordinary goats and goats producers of a biosimilar human lactoferrin has been established. The average values of the mass fraction of fat, protein, lactose, nonfat milk solids, density index in the second and third quarters were lower than in the first and fourth quarters. At the same time, the difference between the spring-summer and autumn-winter periods in the mass fraction of fat was 25%. In the mass fraction of protein, lactose, nonfat milk solids, density it was 5–7%. Comparative analysis of milk from goats-producers of a biosimilar human lactoferrin of various lactations revealed a number of changes in the physicochemical composition of raw materials in comparison with non-transgenic animals: an increase in the mass fraction of protein by 4–6% (P˂0.05), of lactose by 2–6 (P˂0.05), nonfat milk solids by 1–6, density by 2–5% (P˂0.05), freezing temperature by 5 and a decrease in the mass fraction of fat by 5–8% (P˂0, 05). At the same time, the indicators of active and titratable acidity of milk were similar in all groups of animals. At the same time, the concentration of human lactoferrin in the milk of producers of the second and third lactation had almost identical seasonal changes in the increase and decrease in the synthesis of lactoferrin in the mammary gland during the year: in the first quarter – 2.88 and 2.97 g/l, in the second – 4.76 and 4.63, in the third – 7.44 and 7.55 and in the fourth – 7.97 and 6.72 with an average annual value of 5.84 and 5.72 g/l, respectively.

The analysis of literature sources on the question of the relevance of the influence of raw milk and its casein fraction on the production of rennet cheeses is presented in the paper. The studies were conducted to determine the suitability of using milk for the production of rennet milk from raw materials of cows of Ukrainian brown dairy and Ukrainian black-rumped dairy breeds of the state enterprise “Research Institute of Agriculture of the North East of NAAS”. As a result of the studies on the cheesiness of milk samples from the two study groups, we can conclude that, compared to the literature data, the average milk values obtained from cows of Ukrainian brown dairy and Ukrainian black-and-white breeds are confirmed. While analyzing the technological parameters of milk, it should be noted that there is no significant difference between the samples. We should note only that the first sample is inferior to fat by 0.41. This ratio of fat to protein, in turn, affects the yield of the product and its consumption characteristics. The first sample the creation of casein was in 3.2 min. faster , phase of gelforming – for 0.3 min. faster and the clot processing was done requiring 3 min less time. The consumption of milk per 1 kg of cheese in the first sample was lower than 0.4 in the second. It should be noted that the curd grain obtained from the milk of cows of the Ukrainian black-ruby dairy breed had a softer structure, ie it contained more moisture than the grain from the milk of cows of the Ukrainian brown dairy breed. This subsequently affected the mass fraction of moisture in the finished product in the direction of increase and was reflected in the organoleptic evaluation. As a result of the evaluation, members of the tasting committee noted that the consistency, taste and smell of cheese made from milk of Ukrainian brown dairy breed were slightly better. The difference was not significant and was respectively 1 point. It should be noted that the mass fraction of fat in the first sample was 1.3% higher than in the second sample. In this case, we observe a decrease in the mass fraction of moisture in the first sample compared to the second by 1.8%. The difference in terms of mass fraction of salt was not significant and is 0.1%. Considering the results of the presented studies, it should be noted that both samples of cheese of semi-solid cows made of milk of Ukrainian brown dairy and Ukrainian black-and-white breeds meet the requirements of state standart 4669:2006 in terms of organoleptic, physicochemical and microbiological parameters. However, the production of cheese from the milk of cows of Ukrainian brown dairy breed will reduce the loss of raw materials and produce cheese with better organoleptic characteristics.

The article is devoted to the research of legal status of the producers of agricultural raw materials for infant nutrition in Ukraine. It is established that in the legislation of Ukraine there is no single approach to defining the concept of "an agricultural producer", which may create negative consequences in law enforcement. The article highlights the legal issues of general, special and particular legal personality of producers of plant and animal origin for infant nutrition. According to national legislation, producers of agricultural raw materials for baby nutrition are endowed with a special legal personality, which is manifested through the prism of their obligation to produce high-quality and safe agricultural raw materials. The article analyzes the current legal status of special raw material zones for the production of raw materials used for the manufacture of infant nutrition and dietary nutrition. As of 19 July 2019 the Register of Special Raw Zones includes nine businesses that produce agricultural raw materials for baby nutrition. At the same time, such entities mainly produce milk and raw milk, which is due to the statutory state support of those agricultural enterprises that produce ecologically clean milk and raw milk for baby nutrition in special raw material zones. The need to establish a ban on any use of pesticides in special raw material areas is stressed. It is noted that those agribusiness entities that operate in special raw material areas are able to provide baby nutrition producers with environmentally friendly and safe raw materials of animal and plant origin. At the same time, such entities have almost no advantages over agricultural producers without the status of a special raw material zone. The author emphasizes the negative trend of reducing the number of special raw material zones for the production of raw materials used for the manufacture of baby nutrition. Thus, there is an urgent need to create an effective mechanism of state support for agribusiness entities that have received the status of a special raw material zone. The author concludes that agricultural producers who produce raw materials in special raw material zones are endowed with a particular legal personality.

The integrated use of secondary raw milk is one of the most effective ways to optimize the processing of raw materials in the production of dairy products. The unique composition and properties of curd whey makes it a valuable industrial raw material that can be processed into a variety of foods and feed products. Nowadays, whey protein concentrates (WPC) are extremely popular with consumers. One of the promising areas of industrial processing of acid whey is the extraction of proteins by means of separate freezing (cryoconcentration). This process takes place at low temperatures (from 0 to minus 15°C), which makes it possible to preserve the composition and properties of the raw material, prevents denaturation of whey protein fractions, and preserves its valuable thermolabile components. The authors conducted laboratory tests of curd whey and WPC produced by several dairy companies. The research allowed the authors to determine the composition, sensory, physico-chemical, and microbiological properties of the samples. The research objective was to evaluate the sensory properties of the initial cheese whey and WPC obtained by cryoconcentration, to establish their chemical composition, as well as physico-chemical and microbiological parameters. The research also featured the effect of the whey acidity on the WPC output and the development of technological schemes of WPC production by separate freezing. All the samples of curd whey proved to meet the current standards and can be used for WPC production. The sample of laboratory-obtained WPC sample had 20.19% of dry substances and 12.80% of protein, which corresponds to the standard albumin with its 20.0% of dry substances. The titratable acidity of WPC did not exceed the permissible level of 95°T. The experimental results proved that the cryoconcentration technology produced concentrate that met the requirements of regulatory and technical documentation. The obtained data revealed an increase in titratable acidity from 47°T to 50°T during the storage of curd whey for 7 days. The increase in acidity increased the yield of WPC after 7 days of serum storage by 57.6%. The new WPC production scheme consisted of several stages: (1) the whey was obtained; (2) casein dust and dairy fat were excluded; (3) pasteurization; (4) two-stage cryoconcentration; (5) thermal coagulation of whey concentrate; (6) separation of WPC. The technology of cryoconcentrationcurd whey suggests designing industrial installations in-line type to obtain CSB.

Проведена оценка питьевого молока, реализуемого в Самарской области, по сычужной пробе для выявления его пригодности к свертыванию. Исследована способность питьевого молока к образованию сгустка в зависимости от марки, способа упаковки, тепловой обработки и массовой доли жира. Проведен анализ 27 образцов пастеризованного и ультрапастеризованного молока по физико-химическим показателям и сычужной пробе по методикам ГОСТ. Установлено, что питьевое молоко с разной массовой долей жира (от 1,5 до 6,0%) способно к свертыванию, причем эта способность зависит от марки молока и способа его тепловой обработки (пастеризация или ультрапастеризация), но не зависит от способа упаковки и массовой доли жира в молоке. Только в 37% исследованных образцов молоко свернулось, ультрапастеризация оказала негативное влияние на способность к свертыванию. Сделан вывод о предпочтительном использовании молока марок Сарафаново, Пестравка, Ташлинское, Домик в деревне. Также необходимо учитывать нормативные значения рН, титруемую кислотность, плотность и органолептические характеристики молока. Установлено, что питьевое молоко может быть использовано как сырье для производства натурального сырного ароматизатора методом ферментной модификации, обладающего натуральным сырным ароматом без синтетических запахов и придающего вкус продуктам. Evaluation of drinking milk sold in the Samara region, by rennet sample to determine its suitability for coagulation was carried out. The ability of drinking milk to form a clot depending on the brand, method of packaging, heat treatment and fat mass fraction was investigated. The analysis of 27 samples of pasteurized and UHT milk according to physical and chemical parameters and rennet sample according to GOST methods. It is established that drinking milk with different mass fraction of fat (from 1,5 to 6,0%) is capable to coagulation, and this ability depends on brand of milk and a way of its heat treatment (pasteurization or ultra pasteurization), but does not depend on the method of packaging and the mass fraction of fat in milk. It is seen from 27 samples’ analysis, that only 37% of the milk was coagulated, and ultra pasteurization has a negative impact on the ability to coagulate. It is preferable to choose such brands as Sarafanovo, Pestravka, Tashlinskoe, Domik v derevne. It is also necessary to other points of consider are the normative values of pH, titratable acidity, density and organoleptic characteristics of milk. It was established that drinking milk can be used as a raw material for production of natural cheese flavoring by enzyme modification which has a natural cheese flavor without synthetic smells and makes products flavored.

The article raises the problem of ensuring metrological traceability of the measurement results of indicators of quality and nutritional value for food products and food raw materials: water (moisture), nitrogen (protein, crude protein), fat, ash and carbohydrates. The problem under consideration can be solved by applying reference materials of food composition, traceable to state primary measurement standards GET 173-2017 and GET 176-2019 and primary reference measurement procedures (PRMP), for attestation of measurement procedures and accuracy checking of measurement results. The article discusses the results of the PRMP development of mass fraction of fat, ash and carbohydrates in food products and food raw materials, as well as mass fraction of crude fat (oil content) in oil crops seeds and products based on them. The paper also presents metrological characteristics of reference materials of composition of dry dairy products, grain-milk dry porridges for nutrition of babies, grain dry porridges for nutrition of babies, egg powder, freeze-dried meat products, animal feed. The results of the work allow for building a chain of metrological traceability from GET 173-2017, GET 176-2019 and PRMP to routine measurement procedures, thereby ensuring the uniformity of measurements of nutritional value of food products.

Domiati cheese is the most popular brand of cheese ripened in brine in the Middle East in terms of consumed quantities. This study was performed to investigate the impact of the microbiological quality of the used raw materials, the applied traditional processing techniques and ripening period on the quality and safety of the produced cheese. Three hundred random composite samples were collected from three factories at Fayoum Governorate, Egypt. Collected samples represent twenty-five each of: raw milk, table salt, calf rennet, microbial rennet, water, environmental air, whey, fresh cheese, ripened cheese & swabs from: worker hands; cheese molds and utensils; tanks. All samples were examined microbiologically for Standard Plate Count (SPC), coliforms count, Staphylococcus aureus (S. aureus) count, total yeast & mould count, presence of E. coli, Salmonellae and Listeria monocytogenes (L. monocytogenes). The mean value of SPC, coliforms, S. aureus and total yeast & mould counts ranged from (79×102 CFU/m3 for air to 13×108 CFU/g for fresh cheese), (7×102 MPN/ cm2 for tank swabs to 80×106 MPN/ml for raw milk), (9×102 CFU/g for salt to 69×106 CFU/g for fresh cheese) and (2×102 CFU/cm2 for hand swabs to 60×104 CFU/g for fresh cheese), respectively. Whereas, E. coli, Salmonella and L. monocytogenes failed to be detected in all examined samples. There were significant differences in all determined microbiological parameters (p ≤0.05) between fresh and ripened cheese which may be attributed to different adverse conditions such as water activity, pH, salt content and temperature carried out to improve the quality of the product.
