The role of human capital in the innovative development of the Ukrainian economy, which is formed through investment in the human being, is investigated. It is determined that an indispensable condition for sustainable development of the country is the implementation of the strategy of increasing the quality of human capital, which is actively involved in innovation processes and serves as a key resource for improving the competitiveness of the national economy. Emphasis is placed introduction of the model "lifelong learning" using modern technologies. A methodological approach to determining the level of innovative development of human capital is proposed and the value of the integral index of innovative development of human capital is calculated. The innovative-investment model of human capital development in the conditions of globalization is developed and the directions are defined. To overcome the problems of inefficient development of human capital and to improve its quality, a set of measures will be proposed that will contribute to the innovative development of the economy. The scientific novelty is to deepen theoretical provisions and to develop scientific and practical recommendations for improving the quality of human capital and its innovative development in the context of accelerating globalization processes.

E-commerce is one of the fastest and most effective ways to trade in e-space. The leading role in the development of the digital economy and e-commerce belongs to the EU countries that use e-commerce to achieve the goals of sustainable development. The main target of e-commerce companies is to ensure the flexibility and adaptability of the e-commerce development management system. Purpose: to research of the state and prospects of e-commerce development in the EU countries, as well as the content and components of e-commerce development process management. Methods: systematization, generalization, comparative analysis, correlation analysis to build a correlation matrix. Results. The state of e-commerce in the EU countries is studied (according to the following indicators: the share of e-commerce in the total retail sales of individual EU countries, the share of the population shopping online, turnover from e-commerce in small businesses in the EU, etc.). A correlation analysis of the main indicators used to assess the market of electronic trade in the EU, the results of which proved that there is a direct relationship between the dynamics of these indicators and the dynamics of operating profits of enterprises in the EU.

The issue related to the possibility of applying the filtration process of young beer with the use of experimental microfiltration polymer semi-permeable membrane elements was considered. It was shown that under modern conditions, it is expedient to use membrane processes of young beer filtration in the brewing industry. The process of membrane treatment of beer can be carried out at the stage of pasteurization of young beer in a cold way. Such actions can be directed to preserve the organoleptic parameters of the final product ‒ filtered beer. An experimental setup for the study of the main technological parameters of membrane processing of young beer was presented. The results of experimental studies of the influence of baric and temperature modes on the performance of nuclear microfiltration polymer membranes were shown. Rational parameters of pressure (0.03–0.05 MPa), duration (8–10 s-1), and temperature (3...6 °С) of the process of membrane filtration of young beer using nuclear microfiltration polymer membranes were determined. The qualitative characteristics of filtered beer obtained by membrane methods were explored. The comparative characteristic of the results of the studies of the qualitative component of resulting beer after microfiltration according to the known requirements and standards for organoleptic indicators was presented. It is found that in terms of filtration rate, selectivity, yeast residue, and other characteristics, nuclear microfiltration polymer membranes are promising for the implementation of the process of microfiltration of young beer. These studies proved the feasibility of further research into improving the process of membrane processing of beer and technical equipment of the beer production line with the development of new equipment.

The object of research: the process of membrane concentration of buttermilk using methods of removing the polarizing layer on the membrane surface. Investigated problem: determination of the effectiveness of methods for eliminating the polarization layer on the membrane surface during membrane concentration of buttermilk. Main scientific results: The results of experimental studies on methods of removing the polarization layer to increase the productivity of ultrafiltration equipment in the process of membrane concentration of buttermilk are presented. Mathematical models are proposed based on the regression equation of a factorial experiment using the elimination of the polarization layer on the membrane to determine the rational operating parameters of the membrane concentration of buttermilk. These parameters were determined: pressure – 0.4 … 0.5 MPa, buttermilk temperature – 40 … 50 °С, speed of pulsating flows – 1.5 … 1.7 m/s, frequency of bubbling of raw materials – 0 , 10 … 0.15 min-1, bubbling pressure – 0.56 … 0.58 MPa. A comparative analysis of the application of the method of vibrational mixing and bubbling of separated non-fat dairy raw materials to eliminate the formation of a polarization layer on the surface of membranes in the process of membrane concentration is presented. Based on the obtained quantitative and qualitative characteristics of the ultrafiltration products, it can be seen that vibrational mixing and bubbling of the processed buttermilk equally intensify the process of membrane concentration of buttermilk. The area of practical use of the research results: enterprises of the dairy industry of the food industry, engaged in waste-free processing of dairy raw materials and its by-products. An innovative technological product: devices for reducing the polarization layer, allowing to increase the performance of membranes in the process of membrane concentration of buttermilk. Scope of application of the innovative technological product: waste-free processing of dairy raw materials at dairies and dairy plants and other food industry enterprises.
