The theory, methodology and practice of research of socioeconomic and theoretical-methodological aspects of sustainable development are at the stage of comprehension. These provisions are rather poorly elaborated at the level of regional economy. However, the negative events in the economic, political, environmental and social spheres, which we are witnessing, confirm the high significance of this scientific agenda. The authors see the strategic vector of socio-economic development of the regions of the Russian Federation in the context of reducing spatial disproportions, which will ensure sustainable socio-economic development of the entire state, as well as its constituent regions. The research presented in this article is aimed at substantiating the most important factor of sustainable development dynamics of the Russian Federation, namely, overcoming spatial disproportions between the regions that make up the state. The methodological basis of the study is based on the findings and conclusions of scientists who study the problems of sustainable socioeconomic development, as well as those working in the field of regional economics. The research methodology is based on the approaches of formalization and systematization, bibliometric and content analysis, as well as statistical, analytical, comparative, economic and mathematical methods. Scientific publications of domestic and foreign scientists, normative, analytical, program and strategic materials of the Government of the Russian Federation, state regional authorities formed the information base. The main results of the study are: the nomination and proof of the scientific hypothesis, confirming the importance of the reduction of spatial disparities in the system of factors to ensure sustainable development of the state. The results of the study contribute to the development of theoretical and methodological provisions of regional economics, state management of economic and social processes in order to achieve sustainable development.

The demand for functional and health products, as well as the depletion of traditional raw materials, encourages the use of new types of resources. Aronia melanocarpa is a non-traditional plant raw material that has significant potential but is almost never used in the food industry. The aim of this study is to determine the antioxidant potential of processed products of osmotically dehydrated chokeberry fruits and beer enriched with them. The object of the study is the processing products of osmotically dehydrated chokeberry fruits and beer enriched with them. Chokeberry fruits were dehydrated by osmotic dehydration and drying, ground into powders, and their antioxidant properties were determined. Osmotic solutions and fresh fruits were analyzed for flavonoids, anthocyanins and antioxidant activity. Three experimental samples of beer were produced using traditional technology (K) and with the addition of 6 % (D1) and 10 % (D2) osmotic solutions separated from partially dehydrated fruits. An organoleptic analysis of beer was carried out and its antioxidant activity was determined. The results showed that when using osmotic dehydration, the loss of flavonoids was significantly less (29.74 mg K/100 g) than when using the traditional drying method (39.13 mg K/100 g). When applying the proposed regime of fruit dehydration, about 70 % of anthocyanins are retained. While the traditional method preserves only 59 % of these pigments. The sugar solution on the surface of the fruit prevents significant loss of antioxidant compounds. This explains the higher antioxidant activity (9.86 mmol Trolox/100 g) in samples dehydrated using osmotic dehydration. Adding a chokeberry osmotic solution to beer in an amount of 6–10 % leads to an increase in its antioxidant activity by 9–16 mmol Trolox/100 g [ABSTRACT FROM AUTHOR]
