Abstract The development of new food products enriched with biologically active components is a topical issue for modern food science and practice. Many of these substances are unstable when being incorporated into the food matrix, which demands a study on the possibilities to stabilize them before use. Encapsulation of biologically active substances is a method which provides stability of the substance in the food product. The principles for implementing encapsulation of biologically active substances, especially natural oils, the matrices and the encapsulation methods are discussed in the present review. Data on the impact of key process parameters of encapsulation, the biological value of oils and the opportunities for application of the encapsulated systems in different groups of dairy products are presented.

Analysis of literature data and the results of our own research show that even with intensive rearing of animals with the use of balanced feeding and keeping them in accordance with the technology - it is almost impossible to avoid stress. And especially, excessive man-made load on agroecosystems also has a negative impact on animal life. Factors that cause a decrease in immune status and the emergence of immune pathology in animals include: industrial technology of animal husbandry, chemicalization in crop and livestock production, man-made pressure, dietary imbalance in nutrients and biologically active substances. This increases the impact on the body of heavy metals, which displace nutrients from body tissues, in particular trace elements and replace them in metabolic processes, which is a potential prerequisite for the development of oxidative stress. The mechanism of development of stress reaction of an organism is closely connected with activity of POL (lipid peroxidation) and depression of antioxidant potential. Under these conditions, the ability of the organism to mobilize protective and adaptive capabilities in response to the action of negative factors becomes especially important. Keeping productive animals in adverse conditions, unbalanced feeding are components of immobilization stress, which reduces their productivity, affects reproductive function, metabolic and functional disorders, reducing nonspecific and specific resistance of the organism (Fedoruk & Kravtsiv, 2003; Velychko, 2008; Velychko, 2011). Under conditions of man-caused load on the environment, respectively, and animals – it is promising to develop effective methods for regulating the activity of the enzymatic system of antioxidant protection with the help of biologically active substances, in particular trace elements. The results of research confirm that this has a positive effect on the formation of productive and adaptive properties of animals. The system of antioxidant protection is a necessary part of non-specific reactions of the organism, a component of the processes of its adaptation to environmental conditions, a component of normal life, a factor in maintaining homeostasis. Widespread immunodeficiency and elucidation of the main links of their pathogenesis have exacerbated the problem of regulating disorders of the immune system. Therefore, knowledge of the patterns of formation of the immune status of animals, especially in the early postnatal period, is important in the development of methods for the correction of immunodeficiency, antioxidant protection.

The work presented here is the first to examine the impact of Lactobacillus rhamnosus GG ATCC 53103 and Saccharomyces boulardii metabolites obtained using the author`s method on the formation of biofilm forms of bacteria. The structural components of the probiotic microorganisms were obtained using the method of physical disintegration – low frequency ultrasound waves produced by a G3-109 generator. Metabolites were obtained by cultivating L. rhamnosus and S. boulardii in ultrasound disintegrates of lactobacteria and Saccharomycetes. The impact of biologically active substances on the formation of biofilm of Corynebacterium ulcerans tox+ 112, C. diphtheriae gravis tox+ 108, by antibiotic-resistant Pseudomonas aeruginosa PR, Klebsiella pneumoniae PR, Lelliottia amnigena (Enterobacter amnigenus) PR and P. aeruginosa AТСС 27853 reference strain was studied using the spectrophotometric method. For the first time, we proved that L. rhamnosus GG and S. boulardii metabolites and combinations of metabolites of Saccharomycetes and lactobacteria, obtained by cultivating primary producers in their disintegrates, damage preformed 24-hour biofilms of gram-positive and gram-negative bacteria. The representatives of Corynebacterium exhibited higher sensitivity to the filtrates of disintegrates and products of vital activity of lactobacteria and Saccharomycetes than gram-negative pathogens. High parameters of decrease in optical density of preformed biofilms of Corynebacterium and antibiotic-resistant gram-negative bacteria were observed under the influence of combination of L. rhamnosus GG and S. boulardii metabolites (by 1.3–2.6 times). However, the largest reduction of the optical density of the formed biofilm of all studied strains was observed under the influence of metabolites of lactobacteria (by 1.5–5.3 times). Biologically active substances of L. rhamnosus GG and S. boulardii obtained using the author’s method can be used as candidate preparations which could have a strong influence on the process of the formation of the biofilms and preformed biofilms, and also as a preparations of substitution/addition of therapeutic prescription.

Data on distribution, stocks of commercial and potentially commercial brown algae in the Sakhalin-Kuril region, their extraction, industrial processing, and chemical composition are presented. It is shown that for the preservation of biologically active substances and technically valuable components of laminaria, the use of an IR dryer for its preservation at LLC FIG «BINOM», Aniva, Island Sakhalin was an innovative technological solution. The products that are produced at this enterprise, in particular, dried shredded laminaria (IR drying), dried thalloms in heat dryers equipped with gas air heaters with forced air circulation are high — quality products containing all the biologically active components of natural brown alga. Expanded quality indicators of dried products from the laminaria of Sakhalin-Kuril region are presented. Based on the obtained data, recommendations were developed for the integrated use of algae as an annually renewable aquatic biological resource, traditionally extracted and used as raw materials in the production of food products and biologically active substances. It is shown that, despite the significant reserves of kelp in the far Eastern seas of Russia, they are currently poorly developed by fishing, with the exception of the coastal zone of Western Sakhalin.

Процесс разработки пищевого продукта представляет собой процесс формирования фактуры пищевого объекта, наделенного пищевой ценностью при обеспечении соответствия требованиям пищевой безопасности. В отдельных случаях к разрабатываемому продукту акцентированно предъявляется требование обеспечения выраженной физиологической функциональности. Показатели пищевой безопасности и основные идентификационные показатели пищевой ценности пищевых продуктов регламентируются техническими регламентами ТР ТС 021/2011, ТР ТС 033/2013, ТР ТС 023/2011, ТР ТС 034/2013, ТР ТС 027/2012, ТР ТС (на масложировую продукцию). Физиологическая функциональность продукта ассоциируется с использованием в его рецептуре функциональных ингредиентов, обеспечивающих присутствие в составе продукта определенных биологически активных веществ, доведенных до уровня, соответствующего критериям для пищевой продукции - источника пищевого вещества или других отличительных признаков, а максимальный уровень содержания пищевых и (или) биологически активных веществ в такой продукции не должен превышать верхний безопасный уровень потребления при поступлении из всех возможных источников (при наличии таких уровней). Вместе с тем при разработке продукта недопустимо мало внимания уделяется формированию его потребительской ценности, в то время как именно ценность продукта для потребителя определяет не только его продвижение на рынке, но, что более важно, является носителем концептов полезности, заложенной в продукт при его разработке. Иными словами, актуализация полезности продукта возможна при условии, если продукт воспринимается потребителем как ценный для него продукт. Целью настоящей публикации является изложение методики оценки органолептического восприятия как непрерывно изменяющейся величины. The process of developing a food product is a process of forming a texture of a food object endowed with food value while ensuring compliance with food safety requirements. In some cases, the product being developed is focused on the requirement to provide pronounced physiological functionality. Food safety indicators and main identification indicators of food food value are regulated by technical regulations TR TS 021/2011, TR TS 033/2013, TR TS 023/2011, TR TS 034/2013, TR TS 027/2012, TR TS (for oil and fat products). The physiological functionality of the product is associated with the use of functional ingredients in its formulation, ensuring the presence of certain biologically active substances in the product composition. Brought to a level that meets the criteria for food products - a source of a food substance or other distinguishing features, and the maximum level of food and (or) biologically active substances in such products should not exceed the upper safe level of consumption of such substances when received from all possible sources (if such levels are present). At the same time, when developing a product, it is unacceptable that little attention is paid to the formation of its consumer value, while it is the value of the product for the consumer that determines not only its promotion in the market, but, more importantly, is the carrier of the concepts of utility embedded in the product when developing it. In other words, the actualization of the usefulness of a product is possible provided that the product is perceived by the consumer as a valuable product for it. The purpose of this publication is to present a technique for evaluating organoleptic perception as a continuously varying value.

Endometrial cancer is one of the most frequently diagnosed gynecological neoplasms in developed countries and its incidence is rising. Usually, it is diagnosed in the early stages of the disease and has a good prognosis; however, in later stages, the rate of recurrence reaches up to 60%. The discrepancy in relapse rates is due to the heterogeneity of the group related to the presence of prognostic factors affecting survival parameters. Increased body weight, diabetes, metabolic disturbances and estrogen imbalance are important factors for the pathogenesis of endometrial cancer. Even though prognostic factors such as histopathological grade, clinical stage, histological type and the presence of estrogen and progesterone receptors are well known in endometrial cancer, the search for novel prognostic biomarkers continues. Adipose tissue is an endocrine organ involved in metabolism, immune response and the production of biologically active substances participating in cell growth and differentiation, angiogenesis, apoptosis and carcinogenesis. In this manuscript, we review the impact of factors secreted by the adipose tissue involved in the regulation of glucose and lipid metabolism (leptin, adiponectin, omentin, vaspin, galectins) and factors responsible for homeostasis maintenance, inflammatory processes, angiogenesis and oxidative stress (IL-1β, 6, 8, TNFα, Vascular endothelial growth factor (VEGF), Fibroblast growth factors (FGFs)) in the diagnosis and prognosis of endometrial cancer.

Garden strawberries (Fragaria ananassa) are widely cultivated on the territory of Russia on industrial plantations and private garden plots to obtain the fruits (berries) of this plant and their use as a valuable food product. When harvesting fruits, other parts of the garden strawberry are not used, however, its vegetative parts are a source of biologically active substances (BAS) and are of interest for the pharmaceutical and cosmetic industries [1, 4]. The biological activity of garden strawberry leaf extracts is due to the presence of secondary metabolites of a phenolic nature; their content in raw materials reaches more than 3% in some samples [2, 3]. Considering that the main group of biologically active substances of this raw material are flavonoids, the Department of Pharmacognosy with a course of botany conducted research to develop a method for quantitative determination of the amount of flavonoids in terms of rutin. Spectrophotometry was chosen as the optimal method for assessing the content of this group of substances in medicinal plant raw materials - leaves of garden strawberries, which allows determining the amount of flavonoids in terms of the dominant compound and obtaining reliable and reproducible results of quantitative analysis [8, 11]. The technological properties were studied and a therapeutic dose of dry strawberry extract was proposed, optimal compositions were selected and technologies of sachet-granules with dry strawberry extract were developed. The method for the quantitative determination of flavonoids in terms of rutin was validated. The results of the study can be used in the future in the development of draft regulatory documents for sachet-granules with dry strawberry extract of garden leaves and the study of their pharmacological activity.

An important aspect in the pharmaceutical development of dental medicines is to provide them with a prolonged therapeutic effect while reducing the side effects of drug substances and the possibility of long-term use. This can be achieved by using active components of plant origin. Aim. To develop methods for analyzing biologically active substances in the composition of a new combined dental gel. Materials and methods. The study object was a dental gel containing “Phytodent” complex tincture (PJSC “CPP Chervona zirka”, Ukraine). Based on the analysis of the composition of the tincture it was proposed to carry out standardization by the amount of biologically active substances, namely flavonoids. Identification was carried out by TLC, while the quantitative determination by absorption spectrophotometry, the ultraviolet and visible method by the reaction with aluminum chloride using the standard method calculated with reference to rutin and the absorbance measurement at 406 nm. Results and discussion. As a result of the research, the methods for the analysis of flavonoids in the composition of the new combined gel have been developed. The spectrophotometric method developed is characterized by specificity, accuracy, precision and linearity with r = 0.9998. One of the important issues when using components of plant origin is their stability both during preparation and storage. Using the method developed the stability of flavonoids has been studied depending on pH changes of the carbomer-based dental gel. Conclusions. It has been determined that the methods developed are easily reproducible and allow to identifying and quantifying flavonoids in the dental gel. It has been found that a stable content of flavonoids is characteristic of the carbomer-based gel neutralized to pH values from 5.0 to 6.0.
