Rice grows in selenium content of 0.40mg /kg to 3.0mg In the range of soil /kg, roots naturally absorb organic selenium into the internal circulation system of rice, and participate in protein synthesis through the growth path of crops. Finally, selenium elements from the soil are stored in the rice grains in the form of protein selenium. After harvesting, the selenium content of rice is tested to meet relevant standards, which is called natural Se-rich rice. In recent years, selenium-rich soil resource food is gradually becoming a new hot spot in the market consumption, and entering the people's families who pursue health.
It is understood that the distribution of selenium resources on Earth shows that there are more than 40 countries in the world with selenium deficiency. New Zealand, Japan, Europe and most of the United States are selenium deficient. In the 1980s, the Chinese Academy of Agricultural Sciences investigated the distribution of selenium resources in China and found that about two thirds of China's areas were recognized as selenium-deficient areas in the world, involving more than 600 million people. But at the same time, the investigation and proved that the selenium-deficient soil zone in our country, in the specific geological environment, we found selenium-rich soil areas with different areas and different contents. The selenium-rich soil resource new food industry has experienced a long and slow development. In recent years, under the background of the public's increasing awareness of health, the natural nutrition of selenium-rich soil resource food has attracted more and more public attention. According to statistics, by February this year, the total area of Se-rich soil confirmed by various parts of China reached 62,100 square kilometers, accounting for 0.65% of the total land area. Relevant investigation shows that selenium rich soil resources in China are becoming a new investment hotspot of foreign capital. A top-level design for the exploitation and protection of scarce selenium-rich soil resources and related management measures should be drawn up as soon as possible to make use of the health wealth given by nature to the people, the experts called for.
Selenium (se) is an essential trace element for human and animal life. It can prevent and treat many diseases. The relationship between selenium deficiency and various diseases in humans and animals has been studied for more than 100 years. Selenium is known in the medical community as "heart protector "," natural antidote" and "king of cancer". In the United States, a trial of more than 50,000 participants in five countries since 1996 showed that selenium supplementation could protect 37% of the world's population from cancer, and more than half of those who already had cancer could avoid death. This is the result of a 16-year study by Chinese scientists in an area with a high incidence of liver cancer. Natural selenium products grown in major selenium-rich soil areas will be gathered in Shencheng by the end of this year, and the development achievements in this field will be shown to the public for the first time.
