Aspects of«pasta filata» cheeses production

УДК 637.33

The article presents the results of research aimed at studying the composition and properties of milk obtained in the conditions of the farm enterprise in the Yurginsky district of the Kemerovo Region. In the winter-spring period milk had an increased fat content of 4.5 - 5.0%. Pure taste and flavor of raw milk without foreign flavors and odours give the basis for obtaining cheese with good characteristics. Further work is devoted to the selection of effective conditions for extracting the cheese mass in the production of Pasta Filata cheeses. The options for the production of cheeses with using of citric acid and starter cultures, both individually and in a complex, have been considered. It has been found that the calcium transfer under various acid formation options depends on the following conditions: if a greater amount of lactic acid is formed in the early stages of cheese making, more calcium passes into the serum; if acid formation occurs directly in the cheese dough, in this case more calcium remains in the cheese. It has been found that with additional acidification of milk with a solution of citric acid the cheese mass has gained necessary for the extraction pH 5.3-5.2 for 40-60min. At the same time, it should be noted that the cheese mass has melted and stretched at water temperature of 73-75 0С very well. It was found that the simultaneous use of citric acid and starter cultures makes it possible to obtain cheese with good organoleptic characteristics, this method also makes it possible to obtain a plastic cheese mass and to arrange melting regimes at a cheese dough temperature of 60-62 0С and pH of 5.5-5.8.

УДК 332.122(470.3):311.3:303.722.4:637.4’652

The statistical analysis of the eggs production dynamics per capita in the regions of the Central Federal District in 2010-2016 from the standpoint of selfsufficiency in this product has been carried out. Linear regional models of indicator dynamics have been obtained, the parameters of which reflect the average level and the average annual growth in production. We offer to group the regions according to the egg production level per capita with the help of the psychophysical desirability function of Harrington, the parameters of which are set taking into account the consumption norms and statistical properties of the regional area sampling. This approach allows us to establish a correspondence between the natural values of the indicator and the assessment of the self-sufficiency level.

Prospects for integration development in potato as the northwestern federal district of the russian federation (on the example of Leningrad region)

УДК 338.43:635.21 (470.23)

Trends of potato production in the Russian northwestern federal region over the past ten years have been studied. A comparative analysis with national figures has been also conducted in the work. The hypothesis is that the growth of income and the labor intensity of potato production in the private sector cause the potato production decline in the region and in the country. In this regard, it has been proposed for farms with dairy specialization to produce potato as the main activity in the conditions of the Russian north-west federal region. The main factors of potato competitiveness through the product creation chain have been indicated as well. The main problems leading to low efficiency of potato production have been analyzed on the example of the Leningrad region. The most problematic links in the chain of creating and bringing products to a consumer have been detected. In conditions of price changing large enterprises are the least stable ones concerning economic efficiency. The positive experience of regions integration in the potato production chain has been summarized in the article. It has been proposed on the basis of state-private partnership the wholesale food markets creation according to cooperative principles for the promotion of potato and other vegetable production in St.-Petersburg and large regional centers.

Ecological and economic efficiency of agrotechnical antierosion measures

УДК 332.3:631.6.02

The article analyzes the dependence of the agricultural production reduction at the present stage in connection with the aggravation of environmental problems caused by the influence of active and often irrational activities in the agricultural sector. In Russia the main negative processes leading to land degradation, soil and vegetation cover are: water and wind erosion, overwatering and water-logging, saturation, salinization and alkalinization. Many of these trends are observable in the Tambov region. The emerging economic mechanism is characterized by a lack of commercial interest in the rational use of land resources and, accordingly, of the funds earmarked for environmental measures. The development of agriculture in present- day conditions has to involve a range of varied activities to ensure lands protection from erosion and at the same time their high productivity. For integrated assessment of agrotechnical erosion-preventive measures the author’s interpretation of the environmental and economic efficiency definition has been offered. In the first stage the economic effectiveness of the implemented measures is determined from economic position that is characterized by additional net income. The second stage is determined by environmental benefits as the savings to restore lost soil fertility. In the third phase ecological-economic effectiveness of the complex of measures implemented as the sum of economic and environmental effects is determined. In order to avoid soil depletion and to improve its fertility persistently, to make the harvest sustainable, the nutrient balance should be only positive. This should form the basis for effective cultivation of agricultural crops and rational use of land by erosion preventing.

УДК 633.1:631.51:631.8 (470.331)

As a result of comprehensive studies conducted in the Tver region, on sod-medium sandy loam well cultivated soil peculiarities of yield formation of winter crops (wheat, rye, triticale) under the influence of different methods of main tillage and backgrounds of mineral nutrition are studied. Scheme of experiment included the following options: winter crops (factor A): wheat, rye, triticale; receiving main soil tillage (factor B): moldboard plowing to a depth of 21-22 cm, double disking to a depth of 1416 cm; background of mineral nutrition (factor C): without fertilizers, calculated doses of fertilizers on the 3.5 and 4.5 t of grain from 1 hectare. As a result of experiments it is established that the cultivation of winter triticale, the crops of which provide the maximum yield of grain, both on the background of effective fertility (2.31-2.56 t/ ha) and estimated doses of fertilizer (3.35-3.65 and 4.26-to 4.68 t/ha, respectively) is more preferable. More effective for winter wheat was the use of moldboard plowing, providing the formation of further 0.15 t of grain from 1 ha (9.0 percent), and for winter rye and triticale a double disking, increasing productivity by 0.25-0.31 t/ha (10.815.6%). The estimated doses of mineral fertilizers increased the yield in average by crop on the background of NPK by 3.5 t/ha -by 0.81- 1.13 t/ha (42.6-56.8%), on the background of NPK 4.5 t/ha 1.61- 2.12 t/ha (82.8-102.5%).
