The paper deals with the issues of improving the economic efficiency of grain processing enterprises through the introduction of the developed technologies of extrusion and flour production from extruded grains of the main cereal crops. The comparison of the output norms in the processing of grain from the main cereal crops on the existing and developed technologies was carried out. The calculations of the flour production efficiency showed that the processing of wheat will increase the volume of marketable products by 10.0 %, barley – by 14.8 %, oat – by 22.3 %, in this regard, the profitability of production of new high-yield types of flour will increase: wheat by 15 %, barley – by 29.3 %, oat – by 45.6%. Crops have a higher economic effect in the production of extruded flour due to the low cost of raw materials and a decrease in technological waste.

Five types of cereals (wheat, covered barley, naked barley, covered oats and naked oats) were extruded for 6, 6.5, 7.6, 8.2, 9.1 and 10 seconds with subsequent control of the water and the protein content. The water content statistically significantly (p < 0.001) decreased during all the processing time with the final values of 7.3 %, 6.3 %, 7.2 %, 6.0 % and 6.5 % for wheat, covered barley, naked barley, covered oats and naked oats respectively. The protein content slightly decreased during all the processing time with the final values of 11.51 %, 10.95 %, 14.10 %, 13.01 % and 13.10 % for wheat, covered barley, naked barley, covered oats and naked oats respectively. The effect of processing time on the water content can be modeled by polynomial regression whereas the effect of processing time on the protein content can be modeled by linear regression.

The article is devoted to the problems of protecting and developing traditions and ways of life of indigenous small-numbered peoples of the North through employment. Stability of northern clans is reviewed through the problems related to the development of nature’s potential and the use of the northern territories’ biological resources, the creation of supporting agrarian zones in the inhabited areas and formation of relevant production infrastructure. The article addresses development directions of such traditional industries and trades of the North as reindeer herding, hunting and fishing, and gathering of forest foods. The authors chose for the research the Taymyr Dolgan-Nenets District and the Evenkiysky District of Krasnoyarsk Krai, which are home to a large group of indigenous small-numbered peoples of the North. Research methods include analysis of official and analytical reports, publications, regulations, results of field surveys, and economic calculations. It has been established that the districts under research have substantial resources for the development of traditional northern industries and trades. Having generalized the collected materials, the authors assessed the reserves of the areas’ biological resources, and potential production volumes for the traditional industries and trades, as well as determined locations for production infrastructure facilities. The main constraints to the development of the traditional industries and trades are the poor development of transportation infrastructure, the difficulties related to the export of goods from the areas, the monopolistic nature of the procurement of goods from indigenous peoples, and changes in the state approach to the management of northern territories.

For the organization of complex processing technology of oilseed cruciferous crops in the Siberian region varieties of spring rapeseed (Brassica napus), spring ginger (Camelina sativa) and white mustard (Sinapis alba) were investigated. The short characteristics of rapeseed, ginger and mustard varieties promising for cultivation in agro-climatic conditions of the Krasnoyarsk region are given. Safety indicators were evaluated, concentrations of toxic elements, mycotoxins, benzopyrene of pesticides, radionuclides in grain were determined. It is established that the studied varieties of cruciferous meet the safety requirements in accordance with the Technical regulations of the Customs Union TR CU 015/2011 for all analyzed indicators.

The research is devoted to fortification of cereal groats with iron and zinc using ultrasound. Three factors were studied: ultrasound frequency at levels 35 kHz and 42 kHz; processing time at levels 10, 15, 20, 25 and 30 minutes, and temperature at levels 25, 30, 35, 40, 45, 50, 55 and 60ºC. All factors had statistically significant effects on the absorption of iron and zinc ions both for pearl barley and oat groats, and no interaction effects between factors were found. Four multiple regression models with the coefficients of determination in the range of 0.951 to 0.985 were developed to predict the ions Fe2+ and Zn2+ absorption by cereal groats.
