The article presents the results of biotechnological studies of insects used in fish feed by antioxidant activity. The problem of raw materials of animal origin for feeding fish is an urgent problem of our time. It is aggravated by the shortage, high cost and unstable quality of substrates that are made on the basis of fish meal, meat and bone meal, blood meal, etc. Recently, there has been an increase in research around the world in the search for substitutes for animal feed when growing aquaculture. Orthopteran insects of the cricket species Acheta domesticus are of considerable practical interest as a source of protein and biologically active components necessary for the growth and development of valuable species of fish. Most of the issues related to the technology of growing crickets in artificial conditions and the production of high-quality fodder based on them, remain open today. We chose an optimal diet and identified the most favorable conditions for the breeding of insects in a mini-farm. Studied the qualitative composition of the substrate on the basis of crickets. In order to select the optimal technological regimes for the processing of raw materials on the basis of insects, the total antioxidant activity of aqueous extracts of dried crickets, Daphnia magna Straus crustaceans and Gammarus pulex was determined. For crickets, the activity was 6.288 g of rutin, for daphnia 4.219 g of rutin and for gamarus 6.519 g of rutin per 100 g of absolutely dry sample. It was established that all samples, upon drying dry samples to constant weight at 105 oС, lose the total antioxidant activity.

Expanding research to find sources for new effective and environmentally friendly fish feed additives based on natural plant-based raw materials is a pressing agricultural concern Biotechnology. This is especially true because feed additives for fish farming, as opposed to the use of feed additives for farm animals, come into contact with the environment of reservoirs and, accordingly, can have a significant impact on the ecosystem water environment for all inhabitants of reservoirs for breeding fish as aquaculture. The article presents the results of a biochemical study of the total antioxidant activity of the developed feed additives based on the components of the grain of spring wheat (Triticum) of the Kazan Jubilee and amaranth herbs (Amaranthus cruentus L) Shuntuk varieties from the collection of the botanical garden of the All-Russian Research Institute of Medicinal and Aromatic Plants. We show that when applying the technological equipment for grinding the original components for the preparation of feed additives, the total antioxidant activity of the wheat and amaranth grain fractions after grinding depends on the degree of the grinding or from the variance of component particles after sowing on the Sith. It is shown that when preparing fish feed it is best to use wheat with the size of particles 0.25-0.4 mm, which corresponds to the maximum manifestation of the total antioxidant activity of the crushed grain. For the first time in the experiment revealed a synergistic effect on the manifestation of total antioxidant activity when adding protein-vitamin flour from dry amaranth herb to the crushed wheat grain with a maximum value of 4% of its content from the total mass Feed.

The study of the biological characteristics of feed crops and the use of modern methods in the study of the processes of their selection is relevant for the intensification of feed production. The article presents the results of a biochemical study of the giant VIK-2 (Agrostis gigantea Roth) field birch seed, their sowing and yield properties after thermal dehydration (drying of air-dried samples at 105 oС to constant weight), as well as their total antioxidant activity during germination in the dark. The total antioxidant activity of seeds and seedlings was studied using coulometric analysis and determined using electrogenerated bromine, the samples were analyzed on a certified couponometer Expert-006 (LLC Econix-Expert, Russia) using a certified method. The work shows that, compared with air drying after thermohydration, there is a decrease in the viability and yield properties of seeds. Seed germination decreased by 5.5%, the height of plants at the end of the germination period (on the 14th day after sowing) by 9.4%, the mass of 100 sprouts – by 21.3%, the yield of green mass (microgreen) also by 21.3%. The antioxidant activity of seeds after thermal dehydration also decreased by 21.4%. For the first time, data were obtained on the viability, formation of microgreen biomass and a change in the total antioxidant activity of the seeds of the VIK-2 giant cultivar after thermal dehydration (drying the initial seeds) in the test at 105 °C to constant weight. It was shown that thermal dehydration of seeds at 105 °C significantly affects the viability of seeds and seedlings of a bent field, which is associated with the characteristics of metabolism, forms and state of water activity in cells and tissues of plants.

Relevance. A rare representative of the Apiaceae family the garden chervil is widely used abroad in nutrition and in folk and traditional medicine.Methods. Evaluation of nutritional potential of Anthriscus cerefolium (L.) Hoffm and Anthriscus sylvestris Hoffm grown in Moscow region is achieved using the parameters of ascorbic acid, polyphenols, flavonoids, total antioxidant activity of ethanolic extracts.Results. Garden chervil (Anthriscus cerefolium) was characterized by lower concentrations of ascorbic acid (1.6-1.8 times), phenolics (2.2-2.5 times), flavonoids (1.8-2.2 times), total antioxidant activity (1-1.54 times) and dry matter content (2.4-4.9 times) than wild chervil (Anthriscus sylvestris) but demonstrated significantly higher levels of total dissolved solids. Significantly higher content of dry matter in leaves and especially stems of wild chervil correlates with low nutritional value of stems despite large total mass of plants compared to garden chervil. Contrary to wild chervil, Anthriscus cerefolium recorded unusually high concentrations of carotene in leaves and significantly lower levels of chlorophyll b. Seeds of garden chervil were also characterized by low antioxidant status contrary to wild chervil and seeds of curly parsley. High yield and significant nutritional value of garden chervil indicate important prospects of its wide-scale cultivation in Russia while Anthriscus sylvestris plants seem to be important in breeding processes.

Introduction. The overwhelming number of publications contains only data on the content of individual antioxidants, but not on the overall antioxidant activity of the blood in patients with vibration disease.The aim of the study was to determine the total antioxidant activity of blood serum in patients with vibration disease.Materials and methods. Th e main group consisted of 30 people diagnosed with “Vibration disease” of 1 degree (n=21) and 2 degrees (n=9). Th e control group consisted of 30 clinically healthy men, comparable in age with the main group (p=0.66). Th e total activity of antioxidant systems of blood plasma was evaluated photometrically using the test system “Total antioxidant status-Novo” (“Vector-best”, Russia).Results. The indicator of the total antioxidant status (TAS) was 1,038±0.232 mmol/l in the examined main group, against 1,456±0.225 mmol/l in the examined control group (p<0.000001). Th e coefficient of variation (CV) in patients with vibration disease was 22.35%, 1.45 times higher than in the control group (15.45%). In the main group there was a positive correlation between age and TAS (R=0.525), in the control group there was no such relationship (R=0.095). Th e degree of decrease depended on the severity of vibration disease.Conclusions. 1. The development of vibration disease is accompanied by a decrease in the antioxidant status of blood serum. 2. Th e degree of decrease in the antioxidant status of blood serum correlates with the severity of vibration disease. 3. Reduction of TAS can serve as a pathogenetic justification of the need to include drugs and/or biologically active additives with antioxidant activity in therapy

The analysis of the current state of processing of secondary raw materials of wine-making in Ukraine is given. It is proved that the latter is a rich source of biologically active compounds, including phenolic ones, which makes it possible to use it for the production of a wide range of products (raccoon, polyphenol extracts, tartaric acid, beverages, fertilizers, grape oil, cake, vitamin D, animal feed, food powder, abrasives) with high consumer value for various industries: food, pharmaceutical, perfume and cosmetics, chemical, feed, etc. In the light of modern research, the role of phenolic compounds as essential nutrition factors that cannot remain out of the field of view of physiologists, pharmacologists, and food hygiene specialists is shown. However, currently in Ukraine there are no specialized enterprises for complex processing of secondary raw materials of winemaking; traditional technologies are not effective from a technological, economic and environmental point of view, which indicates not rational use of resources and loss of material resources; there are no systematic studies on physical and chemical, microbiological, Toxicological composition in order to determine the optimal direction of its use. A limiting factor is also the lack of comparative analysis of innovative domestic and foreign technologies for processing secondary raw materials of winemaking. In the vast majority of cases, in particular, combs and pomace are taken out of control to agricultural land without special treatment, which leads to acid soil erosion and pollution of the environment with metabolites of micromycetes, increasing one of the global problems of mankind-environmental. At the present stage of technological development, there are a number of innovative developments in the field of processing secondary raw materials, in particular grape pomace, in order to obtain biologically active additives, the limiting factor for the introduction of which is the lack of domestic and expensive imported equipment. A promising way to solve the existing problems is to create a mechanism that will unite the interests of wineries (producers of secondary raw materials of winemaking), processing enterprises (producers of products from secondary raw materials of winemaking), scientists and potential consumers of innovative products. Consolidation of the above-mentioned institutions and enterprises is possible by creating clusters for the development and implementation of innovative technologies and equipment
