Польза для здоровья от ферментированных функциональных продуктов выражается непосредственно, через взаимодействие живых микроорганизмов, поступивших в организм вместе с пищевыми продуктами или с биологически активными добавками (пробиотический эффект), или косвенно, в результате потребления микробных метаболитов, синтезируемых в процессе ферментирования (биогенный эффект). Целый ряд исследований посвящен потенциалу процесса ферментирования для создания экономически эффективного производства пищевых продуктов с новыми функциональными и потребительскими свойствами. Присутствие в составе субстрата достаточного количества нутриентов (преимущественно сахаров) играет решающую роль в развитии молочнокислых микроорганизмов в процессе ферментирования. В этой связи были исследованы динамики концентрации глюкозы и фруктозы в результате направленной углеводной корректировки субстрата, приготовленного из белокочанной капусты сорта Парус. Установлено, что оптимальным, с точки зрения деструкции сахаров, является консорциум молочнокислых микроорганизмов видов L. casei и L. plantarum. Экспериментально установлено, что только этот консорциум удовлетворяет условие устойчивого синергизма между входящими в него видами микроорганизмов во время основного этапа ферментирования при условии углеводной корректировки сырья. Процесс углеводной корректировки целесообразно использовать при разработке технологии направленной ферментации овощного сырья. The health benefits of fermented functional products are expressed directly, through the interaction of living microorganisms that have entered the body together with food or biologically active additives (probiotic effect), or indirectly, as a result of consumption of microbial metabolites synthesized during fermentation (biogenic effect). A number of studies are devoted to the potential of the fermentation process to create cost-effective food production with new functional and consumer properties. The presence of a sufficient amount of nutrients (mainly sugars) in the substrate plays a crucial role in the development of lactic acid microorganisms during fermentation. In this regard, the dynamics of glucose and fructose concentrations were investigated as a result of directed carbohydrate adjustment of the substrate prepared from white cabbage of the Parus variety. It has been established that the consortium of lactic acid microorganisms of the species L. casei and L. plantarum is optimal from the point of view of the destruction of sugars. It has been experimentally established that only this consortium satisfies the condition of stable synergy between the species of microorganisms included in it during the main stage of fermentation, subject to carbohydrate adjustment of raw materials. It is advisable to use the process of carbohydrate correction in the development of technology for directed fermentation of vegetable raw materials.

The article presents a reasonable analysis and relevance of the study of the drying process of vegetable raw materials (colloidal capillary-porous materials). Drying is an energy-intensive industrial process that is defined from a technological point of view: on the one hand by heat and moisture exchange between the body surface and the environment, on the other hand by heating the body and transferring moisture inside it due to the form of moisture. One of the most effective ways to increase the shelf life of food is to dry it to equilibrium humidity. Very important are the technological parameters of the drying regimes, which, when used rationally, are able to preserve the biochemical properties and nutrients of the raw material at a high level in the obtained dry product. The study of dehydration of vegetable raw materials is widely practiced around the world, especially in countries such as Germany, France, USA, Argentina, Hungary, Brazil, Poland, Korea, China, Malaysia. However, the obtained processed products lose their biologically active components and nutrients, and the processing process is energy consuming. Therefore, the problem is relevant and needs an effective solution. In this paper, the kinetics of the drying process, thermogravimetric studies and a mathematical model for colloidal capillary-porous materials of plant origin were analyzed. According to the results of the highlighted research, the process of convective drying of colloidal capillary-porous materials was intensified above 21% due to the use of innovative step regimes. The developed beet-rhubarb composition is a colloidal capillary-porous material that stabilizes and protects at the biochemical level betanin of the beet from the effects of temperature during convective drying, has in comparison with the components of the composition lower heat of dehydration and increased thermal-stability. Prolonged high-temperature exposure causes instant complete destruction of sugars, proteins and other nutrients components. Derivatographic studies have confirmed that the use of the temperature range of 100 ° C in a stepwise mode of 100/60 ° C for the developed soybean-spinach composition is safe for biologically active substances and it is justified by experimental temperature curves. Numerical modeling of heat and mass transfer during convective drying of crushed beets and crushed soybeans using the known model by A.V. Lykov satisfactorily describes the process and can be used to model the convection drying of colloidal capillary-porous materials.

Medicinal plants contain biologically active substances that have a physiological effect on the human body. In the territory of Ukraine, 15 of the most important medicinal plants grow from a medical point of view, among which are Melissa officinalis L and Сalendula officinalis. Micronutrients are necessary for the body in small quantities, not being a source of energy, they take part in their assimilation, as well as in the regulation of various functions and the implementation of the processes of growth and development of the human body. The study aims to establish the micronutrient profile of extracts and infusions from medicinal raw materials – Сalendula officinalis and Melissa officinalis. The established micronutrient profile includes data on the content of such macro- and microelements as calcium, potassium, sodium, iron, zinc, and copper in extracts and infusions from Melissa officinalis L officinalis L and Сalendula officinalis. Sodium predominates from certain macronutrients, the superiority of which is manifested in Сalendula officinalis when infused. A large amount of calcium also passes into the aqueous-alcoholic infusion from Сalendula officinalis. Copper and zinc prevail among the determined microelements in water extracts of Сalendula officinalis. Comparing the results obtained, we can say in the affirmative about the micro- and macro elements that have passed into extracts that Сalendula officinalis is richer in these substances. Because infusions and extracts are recommended to be added as an additional ingredient to vegetable and fruit juices, their positive infusion on the human body will increase the recommended daily requirement of potassium and sodium. Based on the results of this study, extracts and infusions of Melissa officinalis L and Сalendula officinalis can be considered as an essential source of micronutrients for enriching fruit and vegetable juices in canned food for health purposes

At present, the problem of rational nutrition for the elderly is extremely urgent, since every fourth Ukrainian is a retiree by age. Rationally built nutrition for such people contributes to the better functioning of all important organs and systems, increases the level of the body's protective response to adverse environmental factors. Various ways to improve the product to give it a herodetic orientation are offered. According to the concept of balanced nutrition, the structure of the diet of an aging person and its energy value should be correlated with the functional state of the enzyme systems responsible for the assimilation of food, taking into account the physiological needs of the body for nutrients and energy, according to age and health, which is especially important for seniors and seniors. From the point of view of gerontology and old age hygiene, such trends in society dictate the need for accurate and deep knowledge of aging processes at all levels of biological organization, from molecular to holistic organism in order to develop a nutritional diet that promotes aging, preventing aging lifestyle. The need for rational nutrition of the elderly puts forward the task of creating an assortment of products nutritionally adequate to the specifics of their nutrition, taking into account the most common pathologies. In the production of hereditary products, the most appropriate is the partial replacement of traditional raw materials with non-traditional, the introduction of dietary and biologically-active additives, the use of secondary raw materials and non-traditional vegetable (medicinal plants, berry syrups, vegetable oils). This makes it possible to create balanced for all criteria products for the elderly, whose production takes into account all age characteristics.

Relevance. Cabbage is one of the most popular products, which is mainly fermented with the addition of various vegetables. When fermentation is not only the original nutrients such as vitamin C, amino acids, dietary fibers, etc., but also develop functional microorganisms such as lactic acid bacteria. Fermentation has an important effect on the quality and taste of cabbage, so it is important to study the fermentation process, microbial diversity and changes in nutrients and chemical elements in the fermentation process. L. mesenteroides is considered to be the dominant species on heterofermentative early stages of fermentation. However, there is little information on the diversity of species and strains of Leuconostoc involved in fermentation of sauerkraut. Studies that used traditional biochemical methods to study fermentation of sauerkraut showed that four main types of lactic acid bacteria were involved in the fermentation process: Leuconostoc mesenteroides, Lactobacillus plantarum, Pediococcus pentosaceus and Lactobacillus brevis. Taking into account the importance of two-stage fermentation of vegetable raw materials in order to create optimal conditions for the development of the "main" pool of lactic acid microorganisms at the first stage, it becomes urgent to conduct a complex of studies aimed at reproducing the "natural" process in which the main role is played by bacteria of the genus Leuconostoc mesenteroides at the second stage – monocultures of lactic acid microorganisms and their consortia.Methods. The paper studies the dynamics of the type of interaction of lactic acid microorganisms in paired consortiums on model media pretreated by the culture of the species Leuconostoc mesenteroides, at the main stage of step fermentation of white cabbage of the "Parus" variety.Results. It is established that the sum of the criteria, the consortium "L. mesenteroides \ L. casei + L. plantarum" demonstrates the most pronounced advantage compared with monoculture cultivation of appropriate format of pseudotensorial; despite the pronounced synergy in the cultivation of the consortium "L. mesenteroides \ L. brevis + L. plantarum", the dynamics of the comparison index on the rate of increase in the concentration of microorganisms indicates the need for additional research.

Considered the technology for the production of edible powders from vegetable raw materials. The technology for producing powders from berries is developed to produce a high-quality product in which all ingredients of raw materials are stored in a concentrated form.The current trend in nutrition is related to the expansion of the range of functional products whose daily use contributes to the prevention of hypovitaminoses and metabolic disorders, and ultimately to the rehabilitation of the population. New, non-traditional sources of local raw materials, including plant based products, need to be explored and exploited in order to address the issue of instantiate new generation of healthy foods, and the development of technologies for obtaining functionalities. The use of fruit crops, the most source of biologically active substances, is very promising in this direction.The Department of Preservation Technology of the National University Food Technology has conducted a study to enable the use of fruit and berries for food powders. To this end, powder has been obtained from the blueberry berries of ordinary, with the establishment of its physico-chemical properties.The patterns of the influence of the blueberry powder on the functional properties of the foodstuffs were investigated in the example of tomato sauces.Analysis of the results of the studies has shown that a blueberry berry powder can be used in the production of canned and other products not only to enrich their functional ingredients but also to provide them with new technological properties. The food powders received do not contain harmful impurities, have high food value, are easily absorbed by the body, compact and long periods of time. Studies have shown that the blueberry powder is a rich source of vitamins (c acid, β-carotene, tocopherol) and can be used successfully in the manufacture of tomato sauces with functional properties.

Direct Fermentation

Fermented cabbage is traditionally produced naturally, where under the action of lactic acid bacteria contained in raw materials, carbohydrates are converted into lactic acid. However, the direct fermentation process does not always lead to an optimal quality product. That is why the use of lactic acid microorganisms is a good alternative to the direct fermentation of cabbage, as with the help of starter cultures the process can be controlled. In this connection, the use of strains of lactic acid microorganisms allows to achieve rapid production of lactic and acetic acids and leads to a rapid decrease in pH, which in turn leads to the suppression of pathogenic microflora, and therefore to the creation of favorable conditions for the fermentation process. The aim of this study was to study the effect of consortia of lactic acid microorganisms on the dynamics of active and titratable acidity in the main stage of fermentation of white cabbage of the variety "Parus". For the study, the prepared modified model medium (MMC) from cabbage was used. In this work, we used lactic acid bacteria Leuconostoc mesenteroides and its consortia: L. mesenteroides + L. casei, L. mesenteroides + L. plantarum, L. mesenteroides + L. brevis, L. mesenteroides + L. casei + L. plantarum, L. mesenteroides + L. plantarum + L. brevis, L. mesenteroides + L. brevis + L. casei. Mathematical processing was carried out according to the obtained experimental data. Analysis of experimental data showed that at the main stage of fermentation the relationship of lactic acid microorganisms in the studied consortia was expressed by synergistic and antagonistic properties. In this case, the best results on the dynamics of growth of active and titratable acidity were obtained in consortiums L. mesenteroides + L. plantarum, L. mesenteroides + L. casei + L. plantarum, L. mesenteroides + L. plantarum + L. brevis.

Relevance. The use of certain single or mixed cultures of lactic acid microorganisms and the mandatory control of the fermentation process of white cabbage are of great importance to ensure that the product is of stable quality without the need for any chemical preservatives or harsh processing conditions. Carbohydrates contained in raw materials play an important role in this process, since carbohydrates are the main source of maintaining the viability of lactic acid microorganisms. By adjusting the carbohydrate component of raw materials at different stages of fermentation, it is possible to maintain a high titer of microorganisms, while obtaining not only a high-quality product, but also giving it, along with prebiotic (a source of fiber) and probiotic properties. Materials and methods. The purpose of this research work was to ensure the direction of the biotechnological process in the direction of stabilization of the concentration of functional microflora (starting systems of lactic acid microorganisms), under the influence of introduced carbohydrate nutrients. In this work, we studied two fermentation systems of microorganisms that are fundamental microorganisms in the fermentation of cabbage, namely, systems consisting of a pre-fermentation culture of Leuconostoc mesenteroides and one of the cultures of lactobacilli: Lactobacillus plantarum or Lactobacillus brevis. The study used the usual microbiological method for determining the number of microorganisms by seeding in an agarized culture medium, as well as processing experimental data. Results. As a result, we found that the introduction of a carbohydrate Supplement allows us to stabilize the dynamics of changes in the concentration of the studied starting systems at the same initial level throughout the main stage of fermentation.

Relevance and methodology. Today, white cabbage is the most popular type of vegetable raw materials used for fermentation not only in Russia, but also in other countries. To obtain a variety of flavors and shades of flavor, various vegetables (carrots, sweet peppers), fruit (apples, cranberries) and spicy-aromatic additives (cumin, dill seed, etc.) are added to the cabbage during fermentation. During fermentation, the product contains not only the initial components of the raw material (vitamin C, macro-and micronutrients), but also significantly increases the number of lactic acid microorganisms – the main "participants" in the process.One of the main products of the metabolism of lactic acid microorganisms is lactic acid. At a concentration of 0.5%, it begins to inhibit the development of many microorganisms. When reaching a concentration of 1-2% microbiological enzymatic hydrolysis, as a rule, ceases. The accumulation of acetic acid allows us to judge the intensity of the heterofermentative stage of fermentation using strains of lactic acid microorganisms.Results. The L. plantarum + L. casei consortium has shown a synergistic interaction in the accumulation of lactic acid, since the amount of acid produced by the consortium significantly exceeds the amount of acid produced by each strain separately. This point is also noted for the accumulation of acetic acid. In the L. brevis + L. casei consortium, the opposite situation is observed: when using cultures separately, the accumulation of lactic acid occurs to a greater extent than when using two cultures simultaneously. There are no obvious differences between monocultures and the consortium in terms of acetic acid accumulation. In the case of the L. plantarum + L. brevis consortium, we observe a synergistic interaction, with the dominant role in this consortium played by L. plantarum, and the contribution of L. brevis to the accumulation of lactic acid is insignificant. At the same time, the total resulting accumulation of acetic acid is significantly less than the result of each strain separately, which may indicate a negative mutual effect of the participants in the process. Acid degradation of the polysaccharide matrix of cell walls does not occur during the entire fermentation process.
