Abstract

Ensuring the safety of dairy products is one of the components of integrated food safety. The safety of dairy products is directly related to the organization of production control carried out when assessing the quality of water of the centralized drinking water supply system. The article discusses the feasibility of using natural and modified zeolites to ensure water safety. The physical and chemical properties of natural zeolites of the Taizhuzgen and Shankanai deposits of Kazakhstan, the possibility of their use to improve the quality of water in the production of reconstituted dairy products were investigated. The efficiency of water sample purification with modified zeolite of the Shankanai deposit for heavy metal ions was: Pb2+ – 79%, Cd2+ - 98%, Fe2+ - 77%, depending on the initial impurity concentration. It was found that the studied sorbents can be used to improve the quality of water in the production of reconstituted dairy products
