Types of selenium currently on the market

The types of selenium on the market can be roughly divided into three categories: inorganic selenium, organic selenium and ecological selenium. Among them, organic selenium and ecological selenium are safer and easier to absorb selenium nutritional supplements.

1.Organic selenium: including yeast selenium, selenium eggs, selenium-rich algae, selenium-rich mushrooms and selenium malt, among which maltose is the highest stage of organic selenium development, which has better activity than mushroom selenium and yeast selenium, has high utilization rate, no accumulated toxicity, and can be taken for a long time.

Malt selenium is currently the highest stage of selenium development, with high activity, easy absorption, high utilization rate, good taste, safety and non-efficiency, suitable for all kinds of people, and is also a popular selenium raw material in the market.

2.Ecological selenium: including maltoselenium, seaweed selenium, etc., of which maltoselenium is a plant-based organic selenium, and it is also the most easily absorbed selenium element for the human body.

When choosing the type of selenium, you should choose the right selenium supplement based on the individual's health status and needs. It is advisable to consult a medical professional or dietitian for advice if necessary.

Here's what you need to know about selenium:

1. Selenium is a non-metallic element, the chemical symbol is SE, in the periodic table of chemical elements.

is located in the fourth period VI group A (element No. 34). It can be used as a photosensitive material, a catalyst for the electrolytic manganese industry, an essential nutrient element for the animal body and a beneficial nutrient element for plants.

2. Selenium is a red or gray powder with gray metallic luster.

Among the six known solid allotropes.

Of these, the three crystals (monoitrous, monoitrous, and gray triangular crystals) are the most important.

3. Selenium is one of the scattered non-metals, crude selenium is a by-product in the process of copper smelting, and the growth of selenium production has been relatively slow, and the annual amount is limited. The use of selenium is very wide, can be used in metallurgy, glass, ceramics, electronics, Taifu Zhongyang energy, feed and many other fields, and with the development of the world economy and the emergence of new application fields, the downstream demand for selenium continues to grow, to a certain extent, leading to the continuous use of selenium.

However, with the continuous increase of selenium**, its downstream consumption structure will continue to adjust to adapt to the changes in selenium**, and the profit margin of traditional selenium products is expected.

Margins are expected to remain at a medium level, while margins for high-end selenium products with a high technical threshold are expected to remain at a high level.

Chemical properties of selenium:

The first ionization energy is electron volts.

Selenium burns in the air to produce a blue flame to produce selenium dioxide (SEO2). with hydrogen, halogens.

Direct action, and metal can be directly combined to form selenide. It cannot interact with non-oxidizing acids, but it is soluble in concentrated sulfuric acid.

nitric acid and strong alkali. Selenium dioxide is obtained by oxidation for wax hall. Hydrogen selenide, which is soluble in water, causes many heavy metal ions to precipitate into particulate selenides.

Selenium and metals with an oxidation state of +1 can produce two types of selenides, n-selenide (M2Se) and acid selenide (MHSE). positive alkali metals and alkaline earth metals.

An aqueous solution of selenide dissolves elemental selenium to form polyselenium compounds (M2(Se)N), similar to the formation of polysulfides from sulfur.

The best selenium products in China include China Enshi Selenium Tea, Ya'an Selenium Sugar, Changbai Mountain Selenium Rice, Chinese Selenium Yeast, and China Selenium Rich Mineral Water.

1. Enshi Selenium Tea in China: Enshi Selenium Tea is one of the most well-known selenium products in China. The soil in the Enshi area is rich in selenium, so the tea grown here is naturally rich in selenium.

2. Ya'an selenium sugar: Ya'an selenium sugar is a specialty of Ya'an, Sichuan, where the soil has a very high selenium content, so the sugar produced is rich in selenium. This granulated sugar has a pure taste and is a great natural selenium supplement.

3. Changbai Mountain Selenium Rice: Changbai Mountain Selenium Rice is a specialty of Changbai Mountain in Jilin Province, where the soil is rich in selenium, so the rice produced is rich in selenium. This rice has a delicate taste and is a great selenium supplement in the daily diet**.

4. Chinese Selenium Quietly Defeated Yeast: Selenium yeast is a product that enables yeast to absorb and enrich selenium elements through biological fermentation technology. This product is rich in selenium and yeast polysaccharides, making it a great selenium supplement.

5. China's selenium-rich mineral water: In some areas of China, such as Wudalianchi in Heilongjiang and Changde in Hunan, the groundwater is rich in selenium, and the mineral water produced is also rich in selenium. This mineral water has a pure taste and is a great selenium supplement for daily drinking**.

Purple beans, red beans, mung beans, kidney beans, soybeans.

1. Coarse grains and nuts: Soybeans and black beans in coarse grains have a high selenium content, which can be eaten through soybean milk or added to porridge; Among the nuts, you can choose cashew nuts (34 micrograms per 100 grams) and pumpkin seeds (27 micrograms per 100 grams).

2. Animal food: compared with the meat itself, the liver and kidneys are better in selenium, you can choose pork loin, beef kidney, pork liver, duck liver and other foods, if you can't accept this kind of offal products, you can also choose pork, the selenium content of pork is higher than that of other meats, in addition, you can also choose to do eggs randomly, among which the selenium content of goose eggs is higher.

Foods containing selenium:

1. Animal liver:

Pig kidney, beef kidney, duck liver, chicken liver, although the selenium content of animal liver is higher, but after all, it is liver, just eat a little Hu Tan in moderation.

2. Seafood:

Shrimp, marlin, sardines, seaweed, crab, oysters, abalone, dried cuttlefish, dried sea cucumber, dried squid, dried dried shrimp, fragrant sea snail, etc., all contain a lot of selenium.

3. Fish: tuna, salmon, dace, large yellow croaker, herring, hairtail, sea bass, mackerel, mackerel are rich in selenium, and you can eat a little bit of it at ordinary times.

4. Eggs: eggs, duck eggs, goose eggs, per 100 grams of food, eggs contain 23ug of selenium, duck eggs contain 30ug of selenium, goose eggs contain 33ug of selenium, and eggs are best boiled to supplement selenium.

Although butter, fish meal, lobster, mushrooms, pork kidney, garlic and other foods contain a certain amount of selenium, the absorption rate is not ideal. Nutritionists advocate supplementation of organic selenium, such as selenate polysaccharides, selenium yeast, selenium eggs, selenium-rich mushrooms, selenium-rich malt, selenium-rich gastrodia, selenium-rich tea, selenium-rich rice, etc.

Selenium intake is more related to the selenium content of the soil than to dietary patterns. Soils in the United States and Canada appear to contain enough selenium. A study of vegetarians and vegans in the United States found that they consumed enough selenium.

Selenium is found in many foods, but it's especially found in brazil nuts, whole grains (whole wheat bread, oatmeal, barley), white rice, and legumes.

Eggs contain more selenium than meat, and per 100 grams of food, pork contains micrograms of selenium, eggs contain micrograms of selenium, duck eggs contain micrograms of selenium, goose eggs contain micrograms of selenium, ginseng contains 15 micrograms of selenium, and peanuts contain micrograms of selenium. For example, the selenium content of grain produced in China's high selenium areas is as high as 4 8 milligrams per kilogram, while the grain in low selenium areas is milligrams per kilogram, a difference of 1000 times.

Eat selenium-rich foods such as sesame seeds, garlic, asparagus, mushrooms, prawns, tuna, sardines, etc.

Oysters contain the most zinc, followed by malt, yeast, sesame, pork liver, egg yolk, beef, peanut butter, cheese, shrimp, seafood (marine fish), tea, etc.

According to nutritionists from the Municipal Nutrition Society, butter, fish meal, lobster, mushrooms, pig kidneys, garlic and other foods contain a certain amount of selenium, but the absorption rate of the human body is not ideal. Nutritionists advocate supplementation of organic selenium, such as selenate polysaccharides, selenium yeast, selenium eggs, selenium-rich mushrooms, selenium-rich malt, selenium-rich gastrodia, selenium-rich tea, selenium-rich rice, etc.

"Southern Black Sesame" is concerned about the extremely unhealthy status quo of urban overtime workers, and specially launched a new nutritious supper called "10 o'clock in the evening" on the Internet With black sesame, oats, black beans, black rice and other cereals as the main raw materials, maintaining its "black nutrition" characteristics, high nutritional value, and no added sucrose, the stomach is warm after eating at night, no digestive burden, no worry about gaining weight.

Selenium is a non-metallic chemical element with a gray, red crystal or red amorphous powder, with the chemical symbol SE and atomic number 34, belonging to the VIA group of the periodic table. Since the conductive capacity of selenium varies with the intensity of light, it can also be used to make semiconductor transistors and photocells. <

<>1. Selenium is a trace element that is necessary in the human body. Selenium has the effect of improving immunity, so in the current study, it is believed that the deficiency of selenium may be related to the appearance of cancer. Selenium is more common in daily life, mostly contained in food, as long as the food is repented of lead, selenium can meet the needs of the human body normally.

2. Selenium has a high status among the trace elements in the human body, mainly because it can prevent and fight cancer, and can help identify and treat the cell mutation of the human body. Selenium can scavenge free radicals, reduce blood lipids, delay aging, enhance disease resistance, and also have a certain alleviating effect on radiotherapy and chemotherapy for cancer patients.
