M. Ognean, C. Ognean, Simona-Ştefania Hogea
—Buttermilk is a by-product obtained during butter preparation, has a nutritional composition similar to skimmed milk but with an increased proportion of phospholipids. Phospholipids was proved to have functional properties. Buttermilk is produced in large amounts due the preparation of butter and could be considered for use in various food product to obtained functional, sensorial and nutritional improved product. To increase the sustainability we used fresh, unprocessed buttermilk. The aim of this study was to investigate the effects of water replacement in bread formulation with fresh, unpasteurized buttermilk. Dough rheology was improved especially at 50% buttermilk addition and at higher levels did not put on advantage. Bread with added buttermilk showed small improvement of specific volume; denser crumb; pleasant smell and taste; yellowish crumb; darker crust colour. The nutritional value was improved, especially mineral and protein content and amino acid balance. White bread showed more significant improvement of nutritional value.
-脱脂乳是黄油制备过程中产生的副产品,其营养成分与脱脂乳相似,但磷脂的比例增加。磷脂被证明具有功能特性。由于黄油的制备,酪乳可以大量生产,可以考虑在各种食品中使用,以获得功能,感官和营养的改良产品。为了增加可持续性,我们使用了新鲜的、未经加工的酪乳。本研究的目的是研究用新鲜的、未经巴氏消毒的酪乳代替面包配方中的水的影响。酪乳添加量为50%时,面团流变学有明显改善,添加量再高则无明显改善。添加酪乳的面包比容略有改善;密集的碎屑;宜人的气味和味道;黄瓤;外壳颜色较深。营养价值显著提高,尤其是矿物质、蛋白质含量和氨基酸平衡。白面包的营养价值改善更为显著。

B. Tsugkiev, L. Gagieva, V. Cherniavskih, E. Dumacheva, S. Korolkova
The species Sanguisorba officinalis L. is widespread in the Republic of North Ossetia-Alania and is promising for the study and practical use of the pharmacological and food industry. The aim of the work is to analyze the dynamics of biologically active substances in the phytomass S. officinalis depending on the altitude gradient under conditions of RNO-Alania. Studies were carried out in 2012-2016. Samples of vegetable raw materials were taken at 5 stationary points located in various high-altitude belts: 1079, 1480, 1760, 1810 and 2300 m above the sea level. Studies were conducted using standard methods. The air-dry yield of S. officinalis above-ground phytomass in an averaged between 0.669 to 1.05 kg/m over the years of research. The content of the studied biologically active substances in the above-ground phytomass of S. officinalis was found to change with increasing growth height. At a height of 1079 m, a high content of nitrogen-free extractive substances, hydroxycoric acids (in terms of chlorogenic), leukoantocyans, catechins, tanning substances was found in tissues. At a height of 1480 m, the accumulation of crude protein and routine was observed. At an altitude of 1810 m, fiber, ash elements, ascorbic acid, saponins (in terms of ursolic acid), and carotenes accumulate in grass. At a height of 2300 m, plant tissues show maximum levels of crude fat and flavonoids. The obtained data make it possible to estimate antioxidant and P-vitamin properties of S. officinalis and to recommend collection of vegetable raw materials of S. officinalis at different height to obtain certain biologically active substances. Effective and low-toxic natural polyphenolic antioxidants of S. officinalis can be used in the food, cosmetic and pharmaceutical industries. Keywords—Sanguisorba officinalis L., biological resources Caucasus, biologically active substances, antioxidants

Experimental Models of Study and Prevention of Stress in Birds in Industrial Poultry Farming 工业化家禽养殖中鸟类应激的实验模型研究及预防
T. Pogrebnyak, E. Khorolskaya, S. Chernyavskikh, I. Sagalaeva
—In birds, acute stress (a three-day 12-hour inversion of the photomode) is associated with the dominant activity of the sympathetic hypothalamus and hippocampus, which suppress the tone of the parasympathetic section and the reticular formation of the midbrain. The effect of hyperglycemia on the background of a negative chronotropic effect indicates a mismatch of the functions of the autonomic sections of the hypothalamus on the 30 th day. Chronic stress in birds (30-days crowding) causes persistent pathological stress of the functions of the anterior hypothalamus and reticular formation of the middle brain with the suppression of papasympathetic tone of the posterior hypothalamus and high functional activity of the hippocampus, determining the switching of the ventricles of the heart to a more economical mode of functioning by the 30th day. having a cholinoblocking component in the mechanism of its influence during neurogenic stress and in the post-stress period is excluded, but it is possible to use stressprotektors.

—Soil microbial communities perform a number of important functions ensuring fertility. They depend on physical and chemical composition of soil and applied agricultural technology. To control the state of the soil, it is necessary to use methods that allow to quickly assess the dynamics of the structure of microbial communities. To develop convenient method for analysis of microbiota the set of taxon-specific primers for RT PCR, recognizing 16S rRNA genes of domain Bacteria , six bacterial phyla and one class was chosen. Calculation of the percentages of lower-order taxa in the upper-order taxon was carried out based on the number of amplification cycles required to achieve the threshold value of fluorescence intensity taking into account the values of amplification factors. Taxonomic structure of the bacterial component of the soil microbial community was analyzed using as an example a sample of the surface layer of arable black soil enriched with regular application of organic fertilizers. The compiled analysis protocol made it possible to obtain data on the percentages of phyla Firmicutes, Bacteroidetes, Actinobacteria, Verrucomicrobia , and of class Gammaproteobacteria belonging to phylum Proteobacteria

this paper presents the results of a study and modeling of the influence of the solvent’s dielectric constant on the extraction of eugenol from the Laurus nobilis L leaves. The aim of this work is to study the effect of the solvent on the extraction of eugenol from the leaves of Laurus nobilis L., to propose a theoretical model for describing the results. Shredded plant material of Laurus nobilis L. leaves 0.1-0.5 mm. Aqueous solutions of ethanol (23, 39, 55, 73, 80, 96±1% v/v). The extracts were obtained by a ratio of plant materials extractant 1:5 (w/v), insisting for 24 hours at a temperature of 24±1°C. Analysis of the extracts was carried out using reverse phase high performance liquid chromatography and a standard sample of eugenol. The dependence of the concentration of eugenol in alcohol-water extracts on the concentration of ethanol in solution was studied. It was found that the maximum concentration of eugenol is observed in solutions with ethanol concentrations of 85±15 % vol. This range of ethanol concentrations corresponds to a dielectric constant of the solvent of 33.5±3.5 units. The regression equation of the dependence of the concentration of eugenol in the extract on the dielectric constant of alcohol-water solutions is obtained. It was found that the dielectric constant of the solvent has the most significant effect on the process of isolating the phytocomponent from plant materials. A mathematical model is theoretically grounded and tested to describe the dependence of the concentration of eugenol on the dielectric constant of water-ethanol solutions. The optimal range of solvent dielectric constant was found to achieve the maximum concentration of eugenol in the extract. Keywords—Laurus nobilis L. leaves, solvents, HPLC analysis, dielectric constant, eugenol

This range of ethanol concentrations corresponds to a dielectric constant of the solvent of 33.5±3.5 units. The regression equation of the dependence of the concentration of eugenol in the extract on the dielectric constant of alcohol-water solutions is obtained. It was found that the dielectric constant of the solvent has the most significant effect on the process of isolating the phytocomponent from plant materials. A mathematical model is theoretically grounded and tested to describe the dependence of the concentration of eugenol on the dielectric constant of water-ethanol solutions. The optimal range of solvent dielectric constant was found to achieve the maximum concentration of eugenol in the extract.

The technology of anaerobic fermentation of organic substrates and especially of organic wastes with rich microbiota needs effective method to observe the microbial community on the different stages of substrate transformation, including its digestion, fermentation and conversion of its products to methane. The fast and cheap method based on taxon-specific RT PCR is developed to assess density of Archaea and Bacteria population in complex microbial communities. The data obtained on the samples from the industrial biogas plant on the different technological stages are consistent with processes that should evolve during
