In Kazakhstan, within the framework of the Program «Development of domestic value and export-oriented industries», new modern dairy enterprises are being actively modernized and new modern dairy enterprises are being created, where membrane processes are being introduced to concentrate the components of milk. This is necessary for the rational and integrated use of raw materials, including through the processing of secondary resources, the main of which is whey. Improving the production processes of traditional food products and developing innovative ones is possible only with the use of the latest technologies and technological equipment. Membrane processes are widely used for the use of fractionation and concentration of liquid dairy products, which allows for a new solution to the processing of raw materials and opens up opportunities in the development of new types of food products. The article is devoted to the issue of production and processing of whey in Kazakhstan. The main types of membrane technologies and the advantages of their use in the dairy industry in the Republic of Kazakhstan are considered. The role of membrane technologies in the processing of whey is substantiated, various methods of introducing membrane processing methods to ensure the demineralization of whey, obtaining products with high biological value and consumer properties, reducing the cost of energy carriers, reducing the volume of raw materials in order to save transport costs, non-waste processing of milk solids, recycling water are described. This article analyzes the problems of using resource-saving membrane technologies in the production of dairy products in the Republic of Kazakhstan, ways to solve existing problems associated with increasing the economic efficiency of enterprises. The favorable impact of the use of membrane technologies on the social and environmental aspects of whey processing in the country is substantiated.
