One of the most important problems of the population's nutrition is the high caloric content of flour confectionery products, due to their oversaturation with carbohydrate and fat components. This trend leads to micronutrient deficiencies, and later to metabolic problems and deteriorating health. In recent years, there has been an expansion of the range of waffles, improving technology through the wider introduction of various ingredients of plant origin. Crustilian is a crunchy product or component of a dish that has a crispy texture (waffles, cereal breads) or a surface (a crust of bread or potato balls with a fried crust). Crustilian is also used as a layer for cakes or desserts, which usually consists of waffle crumbs, chopped nuts and melted dark chocolate. There are still many variations for making crustilians. The range of applications of crustilian in the manufacture of sweet dishes is extremely wide. The nutritional value of crustilians is determined by the composition of raw materials and can be significantly increased due to the rational selection of components, the introduction of enrichments in the recipe, as well as technological processing, which increases their digestibility. Improving the technology of crucifers waffles by increasing their nutrient density will expand the range of products with functional ingredients, and enrichment of the micronutrient composition due to valuable plant raw materials will improve the nutritional value and organoleptic characteristics of the finished product. A line of crustilians with a high content of biologically active compounds has been developed due to the introduction of superfoods such as flax seeds, sesame seeds, sunflower and walnuts and peanuts into the product formulation. It is established that the use of peanuts and walnuts, in the composition, makes the dough less crispy and more fatty. The presence of flax and sesame does not reduce the crunchiness of the finished product, which is characteristic of crustilians, but, on the contrary, slightly increases this figure. It is proved that the index of nutritional density of crustilian made according to the developed recipe in comparison with the prototype is characterized by an increase in the index of nutritional density in three times, while the mass fraction of the macronutrients increases from 1.26 to 2.5 times, depending on the micronutrient. increases only 1.1 times.

At present, brewing is one of the most dynamically developing branches of the processing industry. To increase the economic efficiency of production and give beer a varied taste in production, it is proposed to use non-traditional plant raw materials. The replacement of expensive brewing malt with unmalted carbohydrate-containing materials is one of the most important and urgent tasks of the brewing industry. This article examines the fermentation process of beer wort with the addition of apple juice and honey base. The lack of nitrogen-containing and phosphorus-containing compounds in honey and fruit wort, consumed by yeast, leads to a slowdown in the fermentation process, a decrease in the rate of reproduction of yeast, and their fermentation activity. In brewing, the fermentation process is the main one, as a result of which the organoleptic characteristics of the finished beer are formed, therefore, great importance is attached to the optimal composition of the medium for fermentation with brewing yeast. To optimize the composition of the wort, it is proposed to use natural sources of assimilable nitrogen and phosphorus, in particular, milk whey up to 20% by volume. In samples of fermented bases with the addition of milk whey, the concentration of alcohol is higher, and the deeper fermentation of the extract is deeper. The dynamics of the fermentation of apple and honey wort with different amounts of milk whey has been investigated, as a result of which it has been established that the introduction of 20% milk whey into the apple wort makes it possible to obtain a drink with the best organoleptic characteristics, as well as to reduce the duration of fermentation to 5 days. When fermenting honey-based wort, you can limit the addition of whey to 20%, which will reduce the fermentation time by 2 days compared to the control sample.

The article provides the results of studies on the influence of temperature conditions of milk fermentation in the manufacture of yogurt on the characteristics of milk clots and the level of EPS production. The characteristics of the samples of reconstituted skim milk fermented by consortia of lactic acid microorganisms for the manufacture of starter and viscous consistency yoghurt starter cultures under temperature conditions are determined: (43 ± 1)°С, (38 ± 1)°С, (35 ± 1)°С and ( 30 ± 1)°С. It was noted that with a decrease in the fermentation temperature from (43±1)°C to (30±1)°С, the organoleptic characteristics of the formed clot are evaluated differently. At the fermentation temperature of (30±1)°С, the lowest degree of syneresis was noted: 45% for the consortium, during the fermentation of milk raw materials forming clumps of inviscid consistency, 29% for the consortium, during the fermentation of milk raw materials forming clumps of viscous consistency. At the same time, it was found that at fermentation temperatures of (43±1)°С and (30±1)°С, the highest level of EPS synthesis for consortia was noted: (2107 ST-A+2674 TL-AV) – 874.6 and 667.9 μg / ml, (1141 ST-AV+2674 TLAV) – 683.9 and 541.3 μg / ml.

В настоящей статье рассматривается зависимость устанавливаемого срока годности безалкогольных напитков от вида потребительской упаковки и ее влияние на сохранность потребительских свойств. В качестве объектов исследования были выбраны безалкогольные газированные напитки на растительном сырье двух наименований. Каждый продукт был расфасован в два вида упаковки - в стеклянную бутылку и в ПЭТ. Опытные образцы подвергли ускоренному старению. Все измерения проводили на 10, 20 и 30 сут. эксперимента, что соответствует 4, 8 и 12 мес. естественного старения. Показатели безопасности образцов в течение и после окончания эксперимента соответствовали требуемым нормам. Было отмечено плавное снижение потребительских свойств напитков, упакованных в стеклянные бутылки. При этом через 30 сут эксперимента (12 мес. естественного старения) физико-химические показатели соответствовали контрольным образцам в пределах допускаемых отклонений. Некоторое ухудшение органолептических характеристик наблюдали лишь к концу заявленного производителем срока годности 12 мес. В напитках, расфасованных в ПЭТ-упаковку, наблюдали более резкое снижение потребительских свойств. При этом производитель заявляет срок их годности также 12 мес. Но уже через 20 сут эксперимента (8 мес. естественного старения) содержание СО2 не соответствовало заявленному производителем. Одновременно было отмечено значительное ухудшение органолептических характеристик. Также было выявлено появление постороннего привкуса в этих образцах, обусловленное, в том числе, приростом содержания ацетальдегида в процессе эксперимента. Проведенные исследования показали, что устанавливая срок годности безалкогольного напитка, производители должны учитывать не только тип, группу и способ обработки напитков, но и вид упаковки, который они используют. This article examines the dependence of the established shelf life of soft drinks on the type of consumer packaging and its impact on the preservation of consumer properties. As the objects of research, two names of soft carbonated drinks based on plant raw materials were selected. Each product was packaged in two types of packaging - in a glass bottle and in PET. Samples underwent accelerated aging. All measurements were carried out on days 10, 20 and 30 of the experiment, which corresponds to 4, 8 and 12 months of natural aging. The safety indicators of the samples during the experiment and after its completion corresponded to the required standards. There was a gradual decline in the consumer properties of beverages packaged in glass bottles. At the same time, after 30 days of the experiment (12 months of natural aging), the physico-chemical indicators corresponded to the control samples within the limits of permissible deviations. Some deterioration in organoleptic characteristics was observed only by the end of the stated shelf life of 12 months. Drinks packaged in PET showed a sharper decrease in consumer properties. At the same time, the manufacturer declares their shelf life is also 12 months. But after 20 days of the experiment (8 months of natural aging), the CO2 content did not correspond to the manufacturer's declared one. At the same time, a significant deterioration in organoleptic characteristics was noted. The appearance of off-flavor in these samples was also revealed. This is explained, among other things, by the increase in the content of acetaldehyde during the experiment. Studies have shown that when setting the shelf life of a soft drink, manufacturers must take into account not only the type, group and way of processing the drinks, but also the type of packaging they use.
