Problems solved by technology

Selenium in natural food alone cannot meet the normal needs of the human body, and inorganic selenium such as sodium selenite has high toxicity and cannot be used in food. Because the source of selenium is very unstable, the selenium content in plant food is 100%. However, animal foods, especially fish, are rich in selenium. However, most of them exist in the form of mercury and cannot be used by humans. Therefore, it is very meaningful to develop selenium-containing foods.
