Abstract
The creation of functional and specialized products from dairy raw materials, in particular those aimed at athletes, is an urgent direction in food technologies. The objects of the study were sports gel samples based on curd whey concentrate obtained by nanofiltration (NF concentrate). To increase the food density of the product, 5% whey protein concentrate was added to the NF concentrate samples: with a protein mass fraction of 30% (KSBUF-30). Rosehip syrup and sucrose were used as an additional source of carbohydrates. To impart a gel structure to the product, the vegetable hydrocolloid c-carrageenan was used in an amount of 0.5%. Ingredients of Russian origin were used in the work. Two options were investigated: with the addition of only fruit-berry syrup (experiment 1) and the addition of a combination of fruit-berry syrup and sucrose (experiment 2). The consumer characteristics of the samples (consistency, appearance, taste and smell, colour) were evaluated by the organoleptic method. At the same time, there were no obvious differences in these indicators. The rheological properties of the samples were investigated by rotational viscometry. Deterioration of structural and mechanical properties, such as loss of viscosity and restoration of the structure in the sample with added sucrose, was established.

Abstract
Dried and powdered fruits of sicilian sumac (Rhus coriaria L., family Anacardiaceae R.Br.) have been used in Asian countries and some others for a very long time as seasoning (spices «sumac», «zatar»). The research is aimed at an assessment of prospects for use of fruits of staghorn sumac (Rhus typhina L.), growing in the middle zone of the Russian Federation, as a spice, having medicinal properties. The morphological and anatomical, dimensional and weight characteristics of Rh. typhina’s fruits, collected in the arboretum of Tsytsin Main Botanical Garden of the Russian Academy of Sciences (MBG RAS), having medicinal properties, were studied. The content of absolutely dry matter and vitamin C in them was determined. For comparison of biochemical parameters, seasoning «sumac» (Rh. coriaria), purchased on open market, was evaluated. It was established that surface of Rh. typhina’s fruit is covered with multicellular trichomes of two types (covering long single-row and glandular capitate on two-celled pedicle); pericarp is differentiated, its structure as a whole is similar to that, described in the literature; the content of absolutely dry matter in air-dry matter (90.5%) and vitamin C (62.0 mg%) in Rh. typhina’s fruits is slightly less than those for Rh. coriaria’s fruits – 96.5% and 64.6 mg%, respectively. Mass of 1000 fruits Rh. typhina (about 12 g) in MBG RAS arboretum is 1,5 times exceed the according to the literature. Thus, Rh. typhina’s fruits may be recommended for further study as an alternative to Rh. coriaria’s fruits, which are traditionally used for making spices.

Abstract
The assessment of the diversity of fungic communities and the study of the bioindicational significance of mycological parameters is relevant for the biomonitoring of ampelocenoses. We studied the quantitative and qualitative composition of saprotrophic micromycetes communities associated with annual shoots of wild and cultivated grape plants. Studies have shown that the number of saprotrophic micromycetes associated with an annual vine is different depending on the place of sampling and ranges from 232.9 … 3203.2 thousand CFU / g dry matter on wild grapes and within 118.9 … 344.1 thousand CFU/g dry matter on cultivated grapes. The highest density indicators of fungal populations - 1119.7 and 3203.2 CFU/g dry matter - were recorded on a vine from forest ecotopes, the lowest indicator of 118.9 CFU/g dry matter was recorded on a vine from ampelocenosis, On wild vines, major share in the studied of fungic communities was occupied by hyphal or mold fungi, on average their share was 95.1%, while yeast occupied 4.2%, and yeast-like fungi - 0.7% of the complex. On cultivated vines, hyphal fungi also occupied the largest part in the structure of fungic communities, but their share was 1.7 times less than on wild plants. Yeast (26.5%) and yeast-like fungi (18.4%) took much larger share.

Published: September 2021

Abstract
Consumers today are focused on safe, organic food. When introduced into the diet of animals, chitosan is able to remove toxic substances, heavy metals, stimulate cellular and humoral immunity, increasing the safety of the livestock. In this regard, the aim of the study was to study the effect of chitosan (group I), ultrafine particles (UFPs) of Fe and Cu (group II) and their combined feeding (group III) on productivity, elemental composition of blood serum and body tissues of broiler chickens. The study was performed on broiler chickens of cross "Arbor Acres" (n = 60) in the conditions of a vivarium. Separate feeding of chitosan and Fe and Cu UFPs is accompanied by an increase in the growth rate of broiler chickens. Their combined use does not give a similar result. Chitosan reduces the absorption of certain elements from the inorganic form of mineral substances. Co-feeding of chitosan with UFPs leads to an increase in the absorption of Fe and its deposition in the liver and feathers.

Abstract
In Sverdlovsk region Holsteinized black-and-white cattle of the Ural type are bred. The herd is represented by large bodied, highly productive animals with a high genetic potential for milk productivity. The aim of the research was to study the productive qualities of Holsteinized black-and-white cattle with a high blood relationship to Holstein breed depending on the line, and correlation between milk yield and live weight of cows. The average milk yield for 305 days of lactation in cows of both lines was almost the same, and the difference between them was insignificant. However, when considering the change in milk yield within the groups, it was found that the group of Reflection Sovering cows featured higher performance indicators – from 8.376 to 14.706 kg of milk. The difference between low productive and high productive cows yield amounted to 6.333 kg or 43.1%. In Vis Back Ideal group of cows the difference was less expressed, and amounted to 5.367 kg or 40.4%. The coefficient of variability in the groups was within the range of 26-28%, which indicates significant fluctuations in milk yield. The yield of nutrients in milk (the amount of milk fat + milk protein) was at the equal level - 783 and 730 kg.

Rational feeding as the basis for the efficiency of pork production (on the example of the Krasnoyarsk Territory)
Authors: Pyzhikova N I , Lazarevich A N , Koloskova Yu I , Vlasova E Yu 
Published: September 2021

Abstract
Modern technologies in pig breeding allow in a short time not only to quantitatively increase the volume of domestic pork production, but also to significantly reduce its cost. The profitability of fattening pigs depends on the value of the average daily gain and the cost of feed for the increase in live weight and the quality of the carcass. These indicators are associated with the genetic characteristics of animals, the composition and amount of feed they consume. Lack of feed and imbalance in diets leads to a decrease in the productivity of animals, therefore, their genetic potential is used in farms only by 60-70% of the possible. Feeding costs account for up to 60% of the total cost of pork production. Fodder production is the main area of innovative activity in animal husbandry, which determines the efficiency of pork production today. The efficiency of feeding is determined primarily by the cost of feed per unit of production. All other things being equal, a better feed payment rate always corresponds to a lower production cost. The use of the technology proposed by the authors allows to reduce the cost of feed in the cost of 1 ton of pig meat by 7.3-12.0%, as a result, to reduce the production cost of manufactured products by 15.5-25.5%.

Published: September 2021

Abstract
Spectroscopic and theoretical calculations have shown that the self-aggregation of tartrazine molecules occurs in an aqueous and water-dimethylsulphaxide solution with a hypochromic effect in their electronic spectra. The deformation of the absorption spectra is accompanied by long-wave broadening. The absorption band of the dye E102 self-aggregates corresponds to the maxima λmax=463nm and λmax=483nm. Studies of the linear dichroism spectra have established that tartrazine self-aggregates, which have a needle-like structure, have optical activity. These data are the passport characteristics of self-assembled tartrazine molecules and they can be used to determine the nativity of dye self-aggregates. It is established that by selecting the concentration and ratios of binary solvent mixtures, it is possible to regulate the number of molecules in the self-aggregated dye molecules. The integration of tartrazine molecules into self-aggregates occurs by Van der Waals forces.
