Разработана рецептура мягкого сыра с повышенным содержанием пищевых волокон за счет внесения отрубей. Для исследования взяты овсяные, пшеничные и ржаные отруби. Рассмотрено 3 способа внесения отрубей на разных технологических стадиях приготовления сыра: образец 1 – перед пастеризацией молока; образец 2 – перед внесением фермента; образец 3 – в готовое сырное зерно. Сыр изготовлен по технологии мягкого сыра (МС) типа «Славянский». Дозировка: на порцию сыра массой 50 гнеобходимо 3 готрубей без учета 3–5% потерь. Определено влагопоглощение овсяных отрубей (ОО) в воде и молоке, %: при температуре t 35°С – 670 и 446, при t 75°С – 840 и 560 соответственно. У пшеничных отрубей влагопоглощение ниже, %: при t 35°С – 760 и 506, при t 75°С – 800 и 533 в воде и молоке соответственно. Физико-химический анализ отрубей: массовая доля, %, пищевых волокон (ПВ) пшеничных, овсяных и ржаных отрубей составила соответственно 60,0; 66,6 и 63,3. Наибольшее содержание ПВ определено в ОО (66,6%). Максимальную оценку дегустаторов получил образец 2 МС. Равномерное распределение отрубей в образце 2 повлияло на его консистенцию и форму, которая сохранялась в течение 12 ч. Установлено, что для получения МС с повышенным содержанием ПВ необходимо добавлять ОО в количестве 6 г/100 г молочной смеси до внесения фермента в заквашенное молоко. Исследования показали возможность создания нового вида молочного продукта с заданными составом и свойствами. A recipe for soft cheese with an increased content of dietary fiber due to the introduction of bran has been developed. Oat, wheat and rye bran were taken for the study. Three ways of bran application at different technological stages of cheese preparation are considered: sample 1 – before pasteurization of milk; sample 2 – before introduction of the enzyme; sample 3 – in the finished cheese grain. The cheese is made using the technology of soft cheese of the «Slavyanskiy» type. Dosage: for a portion of cheese weighing 50 g, you need 3 g of bran without taking into account 3–5% of losses. Moisture absorption of oat bran in water and milk was determined, %: at t 35°C – 670 and 446, at t 75°C – 840 and 560, respectively. In wheat bran, moisture absorption is lower, %: at t 35°C – 760 and 506, at t 75°C – 800 and 533 in water and milk, respectively. Physical and chemical analysis of bran: the mass fraction, %, of dietary fibers of wheat, oat and rye bran was 60,0; 66,6 and 63,3, respectively. The highest content of dietary fiber is found in oat bran (66,6%). The maximum rating of tasters was given to sample 2. The uniform distribution of bran in sample 2 affected its consistency and shape, which was preserved for 12 h. It is established that to obtain soft cheese with a high content of dietary fiber, it is necessary to add oat bran in the amount of 6 g/100 g of the milk mixture before adding the enzyme to the fermented milk. Research has shown that it is possible to create a new type of dairy product with a given composition and properties.

The demand for natural products is constantly growing in the current environmental situation. This encourages manufacturers to increase the production of these goods. However, almost all branches of the food industry use nowadays a large number of biologically active additives, mainly of synthetic origin. In this regard, the introduction of natural vegetable supplements in the composition of a traditional food product will contribute not only to an increase in the nutritional and biological value of the product, but also to expand the range of healthy food products. The possibility of using dietary fiber from root crops of scorzonera, immobilized on biopolymers, and chickpea flour obtained from chickpea beans bioactivated by germination in the amount of 5% and 15%, respectively, was studied in the work. Scientific substantiation of the effectiveness of the use of vegetable filler in the production of combined soft cheese was given. The cheese product produced has a mass fraction of fat in dry matter of 4.5%, a mass fraction of moisture not more than 64%, a mass fraction of salt not more than 2.0%. The use of dietary fiber as a food additive in cheese production gives the product a functional value. Dietary fiber, introduced in an amount of 5.0%, increases the yield of the finished product by 11-11.5%. Thus, applying the proposed technology for the production of a soft cheese product, it becomes possible to solve a number of technological, environmental and economic problems, including an increase in the nutritional value of a soft cheese product, due to enrichment with dietary fiber, macro- and micronutrients, as well as an increase in the biological value of the developed product by balancing the amino acid composition

The existing methods of disinfection of containers for fermented milk products proved to be ineffective. The present research featured an antimicrobial preparation based on silver, copper, and zinc nanoparticles as a disinfectant solution. The authors studied the properties of the antimicrobial in order to prove its effectiveness in processing containers to increase the shelf-life of fermented milk products. The size of the silver nanoparticles ranged from 1 to 10 nm. The nanoscale particles of copper were obtained by the method of electric explosion. It was established that the mass fraction of the active substance (active metals) in the antimicrobial was 50.1%; the mass fraction of water was 11.2%; the mass fraction of hydrogen peroxide was 1.0%. To assess the ability of the antimicrobial to increase shelf-life of fermented milk products, the authors analyzed the microbiological properties of cottage cheese. The 50-gram samples were packed in pre-treated polyethylene containers that had been cleaned with the antimicrobial. After that the samples were left for storage at minus 4 ± 1°C. The quality and the microbiological state of the cottage cheese was evaluated on days 3, 5, 7, 9, 11, and 13, which was justified by the experimental conditions and regulatory documentation. Eventually, it was established that the product contained no pathogenic bacteria, such as L. monocytogenes, Salmonella, E. coli, staphylococci, yeast, molds or any viable microbial cells. It was proved that the test sample retained its consumer properties for 13 days, while the control sample was found unusable by day 7. Thus, by using the antimicrobial, it was possible to increase the shelf life of the dairy product by more than 5 days.
