Silver birch, Betula pendula Roth, is one of the most common trees in Europe. Due to its content of many biologically active substances, it has long been used in medicine and cosmetics, unlike the rare black birch, Betula obscura Kotula. The aim of the study was therefore to compare the antioxidant properties of extracts from the inner and outer bark layers of both birch trees towards the L929 line treated with acetaldehyde. Based on the lactate dehydrogenase test and the MTT test, 10 and 25% concentrations of extracts were selected for the antioxidant evaluation. All extracts at tested concentrations reduced the production of hydrogen peroxide, superoxide anion radical, and 25% extract decreased malonic aldehyde formation in acetaldehyde-treated cells. The chemical composition of bark extracts was accessed by IR and HPLC-PDA methods and surprisingly, revealed a high content of betulin and lupeol in the inner bark extract of B. obscura. Furthermore, IR analysis revealed differences in the chemical composition of the outer bark between black and silver birch extracts, indicating that black birch may be a valuable source of numerous biologically active substances. Further experiments are required to evaluate their potential against neuroinflammation, cancer, viral infections, as well as their usefulness in cosmetology.

Основная задача, возлагаемая на спортивные энергетические напитки - это снабжение атлетов дополнительным импульсом внутренней энергии. В составе разработанного спортивного напитка «Inka Cola» в качестве источника биологически активных веществ использовали экстракт семян южноамериканского кустарника - гуараны. Специфическая черта этого растения заключается в высокой концентрации кофеина в его семенах, содержание которого примерно в 4-5 раз выше, чем в зернах кофе. Наличие в составе напитка «Inka Cola» компонентов, содержащихся в экстракте семян гуараны, позволяет снизить усталость атлетов и обеспечить длительное поддержание высокого уровня их физической и когнитивной активности. В качестве другого источника биологически активных веществ был включен экстракт травы готу-колы, которая произрастает в странах Юго-Восточной Азии. Компоненты, входящие в состав этого продукта, позволяют бороться с эмоциональными расстройствами, способствуют улучшению памяти и восстановлению нервных клеток в мозге человека, а также обладают широким спектром противовоспалительных, иммуностимулирующих, антибактериальных и антиоксидантных свойств. С целью повышения энергетической ценности и улучшения вкусового восприятия напитка «Inka сola» в его состав была включена изомальтулоза - изомер сахарозы с пониженным значением гликемического индекса; для повышения физиологического воздействия на организм спортсменов биогенные минеральные компоненты - калий и магний; для создания гармоничного вкусового восприятия напитка - регулятор кислотности (лимонная кислота) и привлекательных реологических свойств напитка - загуститель (ксантановая камедь). С целью формирования цвето-ароматического образа напитка «Inka cola» в его состав был включен ароматизатор «мохито» и конгруэнтный, то есть соответствующий ему по своему сенсорному восприятию, пищевой краситель. По отзывам спортсменов, использовавших напиток «Inka cola» в течение нескольких недель, у них снижалась утомляемость, им легче становилось воспринимать и усваивать информацию, а также отмечалось усиление физической и умственной выносливости. The main goal of sports energy drinks is to provide athletes with an additional impulse of internal energy. In the composition of the developed sports drink «Inka Cola» as a source of biologically active substances was used an extract of the seeds of the South American shrub - guarana. A specific feature of this plant is the high concentration of caffeine in its seeds, the content of which is about 4-5 times higher than in coffee beans. The inclusion of guarana seed extract in the «Inka Cola» drink composition helps to reduce fatigue of athletes and ensure long-term maintenance of a high level of their physical and cognitive activity. An extract of the gotu-kola herb, which grows in the countries of Southeast Asia, was used as another source of biologically active substances. The constituents of this extract allow to fight emotional disorders, improve memory and restore nerve cells in the human brain. They also have a wide range of anti-inflammatory, immunostimulating, antibacterial and antioxidant properties. In order to increase the energy value and improve the taste perception of the «Inka Cola» drink, isomaltulose, an isomer of sucrose with a reduced glycemic index, was included in its composition; to increase the physiological impact on the athletes were used important biogenic mineral components - potassium and magnesium; to create a harmonious taste perception of the drink - acidity regulator (citric acid) and attractive rheological properties of the drink - thickener (xanthan gum) were included. The formation of the color-aromatic image of the drink «Inka cola» was carried out by using in its composition of the flavoring product «mojito» and congruent food coloring. According to the reviews of athletes who used the «Inka Cola» drink for several weeks, their fatigue decreased, it became easier for them to perceive and assimilate information, as well as an increase in physical and mental endurance was noted.

Introduction. Nutrition has a significant impact on human health, performance, well-being, and lifespan. The research objective was to develop formulations for functional compositions of seafood cryoconcentrates. Study objects and methods. The study featured concentrates obtained by cryotechnology from carcasses of Pacific squid (Todarodes pacificus), muscular shell of cucumaria (Cucumaria japonica), scallop mantle (Mizuhopecten yessoensis), octopus skin (Octopus dofleini), milt of Pacific herring (Pacific herring), and Japanese kelp (Laminaria japonica), as well as their multicomponent mixes. The content of biologically active substances was determined by the spectrophotometric method. The safety and biological value were biotested on Tetrahymena pyriformis. Results and discussion. The dry seafood concentrates had a high content of protein, minerals, and biologically active components, i.e. hexosamines, triterpene glycosides, carotenoids, nucleic acids, etc. The seafood cryoconcentrate mixes were divided into fortifying, restoring, immunomodulating, and mineral. Their chemical composition varied greatly, depending on the functional aim of the mix. For instance, the protein content varied from 28.8 to 57.6%, lipids – from 3.1 to 6.9%, carbohydrates – from 15.0 to 35.9%, minerals – from 10.9 to 22.9%, and hexosamines – from 2.2 to 5.6%. The experiments made it possible to substantiate the composition of the dry mixes. The compilation principle was based on the chemical profile of the raw material, as well as on the choice of biologically active substances. All the dry seafood concentrates showed a high relative biological value. However, the values differed, depending on the type of raw material: from 65.5% for the scallop mantle sample to 86.3% for the octopus skin sample. The difference could be explained by the chemical composition of the cryopowders and their availability to ciliate enzymes. Conclusion. The research resulted in formulations and functional mixes of dry seafood concentrates obtained by cryotechnology. The dry seafood concentrates can be used both independently and as functional compositions. The developed mixes demonstrated rather high content of animal proteins, minerals, and biologically active substance, e.g. hexosamines, triterpene glycosides, carotenoids, nucleic acids, etc. Their functional compositions proved to have excellent sensory properties; they are biologically safe for human consumption and have a high relative biological value.

 The main groups of biologically active substances contained in the bark of Betula pendula were determined by the spectrophotometric method: triterpene saponins, coumarins, hydroxycinnamic acids, tannins. It was found that the place of growth affects the content of triterpene saponins. There is an increase in their content from the anthropogenic load. A comparative analysis of the quantitative content of coumarins in samples of birch bark showed the similarity of indicators, so we can conclude that the place of growth does not significantly affect the content of coumarins. Studies have shown that all the samples under study accumulate approximately the same amount (about 1.5 %) of hydroxycinnamic acids. The difference between the content of the studied substances is small, but it exists. Studies of the content of tannins found that the place of growth of the hanging birch does not significantly affect this indicator. But with the increase in anthropogenic impact, we can note an increase in the content of this group of BAS. The study of the content of amino acids showed that the area of growth of the hanging birch affects their content in the bark. Anthropogenic factors also affect the content of amino acids, with an increase in the anthropogenic load on the growing area, the content of amino acids becomes higher.
