Common selenium-enriched fruits are blackberry, jackfruit and mulberry. Blackberry is generally considered as the fruit with the highest selenium content. Selenium in blackberry is an active organic selenium unique to natural plants, which has many benefits to human body. Generally, every 100 blackberry contains selenium 1 10-270 micrograms. Jackfruit is rich in nutrition and selenium. Generally, every 1000g jackfruit contains about 10 kinds of jackfruit.

47 micrograms of selenium. Jackfruit can be eaten raw or fried. The selenium content in mulberry is also high. Generally, every 1000g mulberry contains about 6 kinds of 0.5 μ g selenium; After drying in the sun, the mulberry contains 34 micrograms of selenium per100g per month.

Research status:

A large number of studies show that the absorption rate of selenium by humans and animals and the biological activity of selenium to humans are that inorganic selenium is lower than organic selenium, and animal selenium is lower than plant selenium. In order to fundamentally eliminate the adverse effects of low selenium environment on human health, people try to transform inorganic selenium into organic selenium with high biological activity and easy absorption and utilization by people and animals.

By organizing selenium by plants, a selenium nutrition model of daily food intake is established to enhance people's physique and protect people's health. Selenium-enriched foods have been developed, including selenium-enriched edible fungi, selenium-enriched algae, selenium-enriched vegetables, selenium-enriched rice, selenium-enriched fruits and so on. The production of selenium-enriched fruits is an important means to improve the level of selenium supplementation in selenium-deficient areas in China and even in the world.
