The role of selenium in nutrition and the manufacturing of selenium-enriched milk

The role of selenium has increased after the discovery of the first seleno-enzyme in the human body. Selenium supports growth, the immune system, the reproductive organs, thyroid and muscle function, has an antioxidant effect, and protects against free radicals. The recommended daily intake of selenium for adults is 55 µg/day, which cannot be covered with food alone in selenium-deficient areas. That is the reason why we chose as our research topic the production of functional food – in this research: milk – in which the selenium level has been elevated naturally.
