Department of Diary, Fat and Cosmetic Science

The Department is engaged in the basic, applied and contract research. Research is focused on properties of milk as a raw material and the development of technological processes in dairy industry and their application in production of milk based foods. In this context, innovative technologies for production of functional foods based on probiotics, prebiotics and biological active components of milk are explored. An indispensable part of the research is study of the main sources of microorganisms in dairy and fat products and of their influence on the shelf life and microbial safety of products. Research in microbiology further focuses on development of starter cultures and their use in the dairy and fat industry. The properties of lactic acid bacteria, their preservative and probiotic effects are investigated as well. Research in the processing of fats includes processes for recovery and refining of oils and fats, modifications of fats and improvement of technologies for production of fat foods and technical fats. Study of physico-chemical properties of surfactants and their use in technology of detergents, industrial and household chemistry and rheological properties of dairy, fat and cosmetic products are other important research areas covered by the Department.
