Generally speaking, selenium-enriched eggs use healthy chickens as transformation factories, and then keep selenium in the chickens to maintain a dynamic balance, and continuously produce high-selenium eggs containing selenium protein. Because the protein chemical composition of eggs is very similar to human protein, the transformed selenium protein can be well absorbed by human body.
In order to reduce the cost, some manufacturers use inorganic sodium selenite as selenium source to produce selenium-enriched eggs. However, in order to prevent the adverse effects on chickens, the additives containing inorganic selenium can only be added intermittently, and the cycle is about one and a half months, otherwise the chickens will only suffer from listlessness, hair loss and even death.
Selenium-enriched eggs belong to functional agricultural products. The national standard is that each kilogram of eggs contains 300-500 micrograms of selenium, and the selenium content in selenium-enriched eggs (20-50 micrograms/egg) is 4-7 times higher than that of ordinary eggs (4-15 micrograms/egg). It has the functions of anti-cancer, prevention and treatment of angina pectoris, myocardial infarction, cerebral thrombosis, rheumatoid arthritis, Kaschin-Beck disease and some toxic substances (cadmium, cadmium, cadmium, potassium, potassium, potassium, potassium, potassium, It also has the functions of scavenging free radicals, stimulating immunoglobulin, maintaining lymphocytes, enhancing immune function, delaying aging and promoting children's growth and development.
