Abstract

Optimum performance of the dairy industry of Belarus requires an improvement in production efficiency. First of all it concerns resource saving, as raw material costs reach 80% of the cost of dairy products. The problem of the shortage of raw materials can be solved through the use of whey, the resources of which in our country exceeds 2 million tonnes per year. When the content in the blood serum of 6% of dry substances, including 0.6% of the protein, we have an annual resource of 12 thousand of tons of protein. However, it should be taken into account that the cost of serum 0, it is included in the costs of production of the product.One of the leading trends of the last few years in the development of the global dairy industry is the widespread use of membrane methods of processing. They opened up opportunities for new types of dairy products and entailed a radical change of the technologies of processing of whey.Nanofiltration allows you to effectively подсгущать serum to 22% of dry substances, which significantly reduces energy consumption during its drying, as well as partially remove the serum from univalent ions Na+, K+, Mg+, Cl -, which allows to achieve the degree of mineralization of up to 30%.
