Ziru night's news, ziru
For the jenan people, the rich melon is almost well known. So far, there are a lot of rich selenium products, such as rice, melon, flour, pear, chestnut, and even milk. In the face of an increasing number of rich selenium products, some citizens are still in the fog. What's the standard? Why is the price of rich selenium more expensive than ordinary products? With these questions, a reporter from the ziru evening newspaper investigated。
Rich selenium is everywhere. What's rich selenium
Now, whether it be on or offline, whether it be agricultural markets in large cities or on the outskirts of the countryside, the wealth of selenium products can be said to be increasing. Not only are there a variety of selenium-rich packaging products, which are in bulk, but in some cases the words “this is rich selenium” are added to the list。
At present, whether food grains, oils, fruits, vegetables, edible bacteria, livestock products, etc., can be rich in selenium. It's like the infeng watermelon is already known, and this year's almonds in the southern mountains are said to have been rich in selenium, and prices have risen significantly。
So what's the rich selenium? In this regard, the journalist interviewed liu yanxiang, director of the professional committee of the shandong association for agricultural technology and economics, and a promoter. Director liu is an expert in selenium in shandong and throughout the country, and has been the authority of the pelican industry for more than 20 years in professional research and promotion。
In 2019, under his leadership, the shandong rural professional technical association and the shandong standardization association issued “group standards for the content of selenium-rich agricultural products and their products”, which fills the gap in the standards for muilium in shandong province. Turning to the rich selenium, liu yanxiang said, “the rich selenium is relative to the poor selenium and its core is quantitative, it is not absolute, it is spatial”. An agricultural product and its products are not rich in selenium with less than 15 μg per kilogram; at the same time, they must be limited to “the maximum intake of adults per day is 400 μg.” if the value of 400 μg is exceeded over a long period of time, it is harmful to humans, “the level of selenium is only useful to humans at a given range”
Thus, in the group criteria, they define selenium-rich agricultural products as follows: “the crops are grown with a natural concentration of selenium or animal foods such as meat, eggs, etc., produced by feeding the glenium feed, and the edible portion of the product is within the range of the criteria”. (b) selenium-rich agricultural products: these are processed primarily as raw materials and are not added after receipt or during processing, and the selenium content meets the requirements of the standard。
The rich selenium must be naturally rich, by biological transformation
Liu yanxiang described the main function of selenium as being resistant to oxidation, i. E., to increase human immunity, prevent disease and slow ageing. For agricultural production, crops can be used to increase fertility and improve quality。
This is because 70 per cent of the country's land is poor, according to director liu, “we all know that health derives from the balance of food and nutrition, and that if there is overnourishment and some trace elements are lacking, it can also affect human health”. Whether there are so many rich selenium products, or because the body lacks selenium, requires scientific residuary selenium, “of course it must be properly filled, not artificially elevated”
How do you fix selenium? At present, the best way to do this is to fill it with food with selenium. But what needs to be strictly pointed out here is that selenium must be organically transformed by life. Director liu said that “the human body of organic selenium is easy to absorb and relatively safe, so crops need to be used to absorb inorganic nutrients into organic nutrients and then be absorbed by humans”
Current production of selenium-rich products is mainly achieved through the spraying of selenium-rich fertilizers, i. E., the use of crops to convert the rich selenium fertilizers into organic nutrients. Spraying, however, requires strict management and regulation. “25 days before any crop is taken, no spraying shall be allowed on the leaves, as 25 days is the peak of inorganic matter converted to organic matter.” according to the above, if the fruit from which it has been harvested is sprayed with fat, even if the test is met, it is pseudo-rich, “the selenium from which the fruit has infiltrated is insufficiently transformed and detrimental to human health”
The use of selenium-containing fat must be appropriate and timely
The proper use of selenium is a prerequisite, i. E. Appropriate, appropriate and timely。
The state of selenium in the soil is different. According to liu yanxiang, there are a few areas in my province that are suitable for selenium. At a concentration of 0. 4-0. 5 ug, the euphoria streets, such as the towns of dragon springs and hongshan and zhuang, in the city of zambo, are suitable areas.” the plume areas include runan and the taian factory, among others; the areas with a severe shortage of selenium are the yellow river alluvial plains, including the east camp, the bay state, etc. Depending on the regional situation, selenium is properly replenished. Because of the different amounts of selenium in the soil itself, the use of selenium fat is scientific。
In addition, it is worth mentioning that crops themselves have different properties and different yields for selenium. For example, garlic is better off with selenium, so it's a relative reduction when it's used. It is important to note that it is either fattening or producing, “must be produced by standard norms”. Director yoonxiang liu said that, as a result of his continuous production of selenium-rich products, he now had access to the ground to develop a targeted programme, and that the agricultural products produced under his programme must be tested in accordance with the standards。
“countries are produced in strict conformity with the labels and are subject to testing, which can only be defined in a reasonable range as being rich in selenium.” for this reason, if someone in the street calls a rich selenium, you can ask for a test report on the content of the selenium. If there is no such test, it cannot be said that it is rich, because there is no knowledge of the content of the selenium, and what is its content? Such cases can be attributed to false propaganda。
28. 8 pounds of rice
When it comes to rich selenium products, it comes to mind that their higher prices may even be several times those of ordinary products。
To that end, journalists visited the mall of the grand yunfa supermarket, where they looked closely at vegetables, fruits and eggs, and did not see the products of the rich selenium. The supermarket is also selling beammelon, but it is not marked as rich. The vegetables in the store were essentially ordinary and organic products, and no vegetables were found rich in selenium. Similarly, in the agricultural market on the western road of chifushan, journalists asked and did not find a certificate-rich selenium product。
At the silver house supermarket on rim hill road, journalists discovered a milk product rich in selenium. The milk is scalded milk produced by ely. It is marked by the words “protocol rich”, as well as by the words “swealth of milk, health and power”. In the nutritional table of the milk, it is clearly stated that 100 ml of selenium contains 7. 5 ug selenium。
According to liu ji-chun, a long-standing seller of selenium products, he had been operating in previous years through a special entity shop near the ten road chemical hotel, and almost all of the province's solenite products were sold. Later, as the situation changed, he now sells mainly through the internet。
With regard to the sale of rich selenium products, liu yanxiang said that, given the limited size and production of many bases, and considering the cost of going to supermarkets, many bases were not able to enter supermarkets on a large scale, and he understood that only one such base was currently selling at supermarkets. Many of them are sold through fixed vendors, pickers, networks, etc. Now, the rich selenium products in shandong are better sold by the rich, rich melons, radiant beryllium flour, smoked platinum-rich apples, and so on。
Ziru evening news ziru, a journalist who is on a treasure-hunting platform, enters the word “rich selenium” and immediately comes up with a long list of products, including rice, melons, groceries, etc. Journalists saw a large north-east five-long rice 50000 grams sold at $28. 8 per pound, while the most expensive real-time price of five days of rice on the fifth day was 4. 97 per pound. The sum of 2,500 grams of melons sold is $49. 9 at a price of nearly $10 per pound, while the price of non-rich cassava is below $1. 8 per pound. Turning to local products in jinan, the rich almonds in the southern mountains are sold at a high price of $15, while the average is $67,000, which is double。
Why is it so expensive? High-quality and priced, but not for sale. Price
Why is it so expensive? In response, director liu said that it was in line with high-quality and high-priced market patterns, but that it could not be sold, and if it was too expensive, it would be detrimental to the industry as a whole。
Why is it expensive? Director liu said that the rich selenium product had a very distinctive feature, which solved the problem of selenium supplementation among the population and facilitated its repair. Selenium-rich products contribute to food safety through their resistance to pests and antiweight metals, degradation of nitrates and inhibition of acrylcin. In addition, the base production of rich selenium products in shandong, mainly in green agriculture, also ensures product safety。
In addition, selenium-rich products optimized crop nutrition. Why do you say that? In fact, liu yanxiang said that there was a barrel theory of nutrition in the crop and that other nutritions had been increased when the short sheet had been filled. “the increase in selenium and the increase in proteins, for example, can raise the fatty pork by about two proteins, and the protein in wheat can rise from 11. 9 to about 12. 5-12. 8.” in this regard, he considers that the pelican product is characterized by a strong sense of wind, nutrition and taste, “the elimination of the chilling intestine irritation and the improvement of the spicy irritation, for example, if you eat pelican garlic”. Finally, the abundance of selenium increases the commerciality of “products that are relatively resistant to storage and transport, and goods whose shelf life is extended”
For these reasons, liu yanxiang believes that the quality and good price of the selenium product is also in line with market law, “it is normal to have high prices relative to the same product, but he is opposed to selling the sky price”. He said that the larger the selenium-rich produce, the lower the corresponding costs, and that the area under cultivation was still limited. He cited, for example, the average cost of wheat-rich fatting to a pound of wheat might be a few cents, but the cost could not be so simple, and the cost of selenium-rich products increased considerably, together with research and development, services, extension, management, etc。
At present, 100,000 acres of selenium produce are being provided with technical support through the shandong monument commission, which has more than 170 bases. It is hoped that, in the future, more products and more areas will be cultivated, which will also make the price of rich selenium more pro-people。
