Description
The article presents the comparative characteristics of the current (diffusion) and developed (diffusion-press) sucrose extraction technology from sugar beet cossettes. We have presented the graphs of the influence of raw juice pumping value on its cleanliness and residual content of sucrose in partially desugared beet cossetes, the influence of partially desugared beet cossetes pressing power on residual content of sucrose in the pressed pulp and losses of sucrose with pressed pulp and also the technological scheme and regimes of diffusion-press extraction of sucrose from sugar beet cossettes. The criteria for determining the boundary parameters of diffusion and press sucrose extraction stages are identified. The comparative assessment of technological and economic indicators of the existing and the developed technologies of sucrose extraction from the beet cossettes is shown. The developed technology allows reducing raw juice pumping value simultaneously increasing its purity, thereby providing reduction of auxiliary materials and energy resources consumption, as well as increasing sugar yield. The technology of diffusion-press extraction of sucrose is implemented on 2 sugar beet factories of the Russian Federation. The economic effect from its implementation is more than 45 mln. rubles

Description
Long-term storage of fruits can be achieved by means of decreasing microbial contamination of their surface as a result of fruits pre-treatment by biopreparations before dispatching for storage. In the current study patterns of influence of fruits pre-treatment with the “Ekstrasol” biopreparation in a number of concentrations of bioagent on the microbial contamination of their surface during storage are revealed. The “Ekstrasol” preparation is a biofungicide, containing the Ch-13 strain of Bacillus subtilis bacteria and their metabolites. As research objects there were chosen apples of a zoned in the Krasnodar region variety called Idared and pears of a zoned in the Krasnodar region variety called Conference, harvested in 2016. The apples and the pears were stored over a period of 6 months in the low temperature conditions. Samples were withdrawn every month over the period of storing. The species composition and quantity of the most prevalent microorganisms, potentially causing the spoilage of apples and pears during storing, were identified. The optimal concentration of the bioagent, which provides the maximal decreasing of microbial contamination of fruits’ (apples and pears) surface, is established – 106 CFU/g, dosage of solution – 1 ml per 100 g of fruit

DescriptionProviding the population with basic food products, sources of proteins, fats, carbohydrates, vitamins and other essential nutrients is one of the main issues of ensuring the security of the country, while the requirement for food safety is paramount. Production of feed additives (concentrates), which improve feed conversion, while being natural and safe for animal health, acquires the greatest importance in the conditions of intensification of agriculture and increasing the competitiveness of livestock farms. Probiotic microflora, which, in competition with pathogenic, displaces the latter from the gastrointestinal tract, can be considered as one of the effective methods of controlling undesirable microflora in the digestive tract. In world science, research is actively conducted in the direction of searching for effective probiotic cultures. A promising way to increase the effectiveness of the use of probiotic feed additives is their addition to prebiotics, for example, including vitamins (antioxidants) and mineral substances (selenium). The purpose of this work was to determine the optimal ratio of biologically active substances contained in the feed vitamin-mineral concentrate, and probiotic microflora contained in the feed probiotic additive Bacell-M, for the development of complex feed concentrate. Using the Harrington's desirability function, the optimum ratio of biologically active substances and probiotic microflora in the recipe of the complex feed concentrate is determined, ensuring the maximum reduction in the serum levels of alanine aminotransferase in the blood serum of experimental animals, which characterizes the normalization of barrier organs

THE EFFECT OF PLANT FOOD ADDITIVES ON THE PROPERTIES OF WHEAT FLOUR AND DOUGH
DescriptionThe article presents data describing composition of macronutrients and food additives "Apple Powder" and food additive "Pumpkin Powder" obtained from secondary resources processing of apples and pumpkins with innovative technology that ensures their high antioxidant activity. Introduction of the studied food additives in wheat flour provides a boost of its antioxidant activity compared to the control (wheat flour without any additives). We have revealed that the introduction of the studied food additives in wheat flour provides a strengthening effect to the gluten flour, while dietary Supplement Powder called "Apple" has a strengthening effect on the gluten of wheat flour compared with a dietary Supplement called "Pumpkin Powder". We proved a positive impact of food additives on the gas-forming ability of wheat flour and water absorption capacity of dough; at he same time, with the same dosage of additives, water absorption capacity of dough with the introduction of additives of "Pumpkin Powder" is higher than this figure with the introduction of the additives of "Apple Powder", due to the higher content of pectin in the additive "Pumpkin Powder " compared with the additive "Apple Powder", having a high water-holding capacity. We have found that the dough with the introduction of the investigated supplements has the best rheological properties in comparison with control samples. The obtained results allow us to develop evidence-based formulation and technological modes of production of bakery products enriched with antioxidant properties, with the use of food additives called " Apple Powder" and "Pumpkin Powder"
