The results of the influence of the mass of planting tubers of Jerusalem artichoke on the size and fractional composition of the crop of tubers in the conditions of sod-podzolic sandy loam soils during autumn planting of tubers are presented. It was found that planting tubers weighing 80-100 g g provide a yield of 45 t/ha. With an increase in the mass of planting tubers, the cost of purchasing planting material increases sharply and profitability decreases. Planting small tubers leads to a decrease in yield.

The author presented experimental data on the influence of technological factors on the quality indexes of tablets based on a cryoliofilized salmonella bacteriophage. The analysis of the technological properties of model granules with such parameters as bulk density, flow ability, vibration compacting index, Hausner index, Сarr's index showed that the fractional composition of the granules should contain no more than 33 % of the pulverized fraction (0,25 mm or less). The granulate, regardless of its fractional composition, has elastic-plastic properties characterizing the strength of the tablets. The influence of the pressing pressure of the cryoliofilized composition tablets with salmonella bacteriophage on the crush strength and disintegration of enteric-soluble tablets was studied. The optimum compression pressure of tablets within 60 mPa of granules with a content of pulp fraction (0.25 mm or less) is not to be higher than 33 %.

For the development of new compositions of modified powder mixtures a comprehensive analysis of the technical characteristics of powder additives is required. The specific surfaces of nanosized powders of "Tarkosil" silicone dioxide were determined by the experimental method. Therefore, at present, the estimating relationships of sizes, particles shapes and specific surface area of nanosized powder is relevant scientific and practical task. And the particles shape was evaluated by the values of these surfaces. Using the method of small-angle scattering the functions of distribution of the modifying powders particles on their sizes were estimated, and the average values of particles size of "Tarkosil" powder were specified The particle shape of the modifying powders has been estimated according to the specific surface values. The particle shapes of T50 powders are close to isometric (a ball, a cube); particle shapes of T150 powders correspond to a tetrahedron, the particle size T80 and T110 corresponds to the intermediate value of the specific surface area.

The Subject

Grinding or crushing hard raw materials is usually a primary operation which precedes the follow-up technological processes in a number of industrial sectors. A great variety of machines using different principles of fragmentation are employed in the technology of pulverization. The food industry uses roller mills, in which the main process is the shear grinding. In the animal feed industry impact machines known as hammer mills are often used. In recent years, mills have been employed that use their frontal edges for grinding or crushing during the rotation of one of two adjacent discs. The modern design disc machines used for grinding grain have resulted from long development and their operation has a relatively low noise level with reduced dust. The separation process that occurs in the gap between the active edges of the discs can be described as shear grinding and is currently the subject of attention which is focused on the specific energy consumption and fractional composition of the product of grinding.

Рассмотрены идентификационные признаки некурительных табачных изделий табака жевательного и снюса. Разработан метод определения фракционного состава табака жевательного. На основании научных исследований впервые разработан проект национального стандарта ГОСТ Р Табак жевательный. Общие технические условия, который после утверждения и введения в действие будет использоваться для идентификации этого вида некурительной табачной продукции. The identification signs of smokeless tobacco products: of chewing tobacco and snus are considered. A method for determining the fractional composition of chewing tobacco has been developed. On the basis of scientific research for the first time developed a draft national standard GOST R Chewing tobacco. General technical specifications. After approval and entry into force, this standard will be used to identify types of smokeless tobacco products.

Исследования фракционного состава белков и жирнокислотного состава масел безалкалоидных и малоалкалоидных сортов люпина для производства кормов и продуктов питания являются актуальными в современных социально-экономических условиях, когда требуется найти альтернативу соевым продуктам. В данной работе изучались фракционный состав белков и жирнокислотный состав масла семян 11 образцов малоалкалоидных сортов люпина отечественной селекции трех видов: белого, желтого и узколистного. Самое высокое содержание сырого протеина выявлено в образцах семян желтого люпина, в семенах белого люпина содержание сырого протеина было немного ниже, а все исследованные образцы сортов узколистного люпина характеризовались самым низким содержанием сырого протеина. Суммарное количество растворимых белков в семенах люпина было высоким и изменялось от 84,21 до 92,45 %. Во всех исследованных образцах сортов белого люпина преобладала альбуминовая фракция, в семенах сортов узколистного и желтого люпина – глобулиновая фракция. Содержание сырого жира в семенах разных сортов изменялось от 4,62 до 9,28%. Обнаружены различия в жирнокислотном составе масла семян люпина разной видовой принадлежности. Жирнокислотный состав семян характеризовался преобладанием олеиновой кислоты в масле семян сортов белого люпина, при явном преобладании линолевой кислоты в сортах желтого и узколистного люпина. Researches of protein fractional composition and fatty-acid composition of nonalkaloid and low-alkaloid lupine varieties oils for food production are actual in modern social and economic conditions, when it is required to find an alternative for soybean products. In the present work, the protein fractional composition and fatty acid composition of seeds of 11 low-alkaloid lupine varieties of domestic selection of three species: white, yellow and narrow-leaved lupine were investigated. The highest content of crude protein was detected in seed samples of yellow lupine, the crude protein content in white lupine seeds was slightly lower, and all the studied samples of narrow-leaved lupine were characterized by the lowest crude protein content. The total amount of soluble proteins in lupine seeds was high and varied from 84,21 to 92,45 %. In all examined samples of white lupine varieties the albumin fraction dominated, while in seeds of narrow-leaved and yellow lupine varieties the globulin fraction dominated. The crude fat content in the seeds of the different varieties varied from 4,62 to 9,28%. Differences were found in the fatty acid composition of lupin seed oil of different species. The fatty-acid composition of seeds was characterized by the predominance of oleic acid in the oil of white lupine varieties, with a clear predominance of linoleic acid in yellow and narrow-leaved lupine varieties.
