As early as the early 1980s, there were a group of scientific elites who stood at the forefront of life science in Peking University, a century-old university by the unnamed lake in Beijing. Under the leadership of Professor Luo Dazhen from Peking University College of Life Sciences, they are committed to the frontier scientific research of bioengineering technology.
After 16 years of hard work and painstaking research, they finally succeeded in introducing selenium into protein, a microorganism beneficial to human body, to transform inorganic selenium compounds into organic selenium and develop selenium-enriched yeast.
Compared with inorganic selenium and other organic selenium, Se-enriched yeast is more easily absorbed by human body, stays in the body for a long time, can fully participate in human physiological and biochemical activities, is conducive to the establishment of selenium reserves in the body, and has high bioavailability, safety and non-toxicity. The successful development of this scientific research achievement of Peking University has filled the domestic gap and solved the world problem of selenium supplementation for human body.
Extended data:
Generally speaking, the total daily requirement of each person, the daily selenium supplement of adults in China is more than 25 micrograms, which has health care function; Adults with selenium deficiency should supplement 50 micrograms or more selenium every day.
Because 72% of the soil in China lacks selenium, the selenium content of cereal crops such as wheat, rice and corn, which are the main food crops, is less than 40 μ g/kg. The daily selenium intake of China people is lower than the minimum intake recommended by the World Health Organization of 50 micrograms, and the daily selenium intake is only 30~45 micrograms, which is lower than that of Japan, Canada, the United States and other countries.
Selenium-enriched rice, 100 microgram (selenium-enriched corn flour), animal offal, fish, seafood, mushrooms, eggs, garlic, ginkgo, etc. are all high in selenium, and people who are deficient in selenium can appropriately increase food in this area.
