Citrus fruit trees
Recently, a small video of a sneak shot was circulated on the Internet. Kan Kan, a grower, talked about how to make his citrus sweet.
When it comes to "cyclamate", many fruits need to be beaten, including watermelons, oranges, grapefruit and oranges.
What exactly is the sodium cyclamate she uses? Will it be toxic? What fruit can I eat in the future?
Food additive sodium cyclamate
The scientific name of sodium cyclamate is "cyclohexyl sulfamic acid", which is a synthetic sweetener.
It is allowed in China, European Union, Hongkong and other countries and regions, but not in the United States, Japan and other countries.
The human body can't absorb it, even if it does, it can't be metabolized, and it will eventually be excreted intact, so it is very safe.
As a sweetener, it is widely used in beverages, canned food, cakes and other foods, but it is not allowed to be used in fresh fruits.
How to beat the sodium cyclamate in fruit?
There are usually two understandings of fruit spraying, one is spraying and the other is injection.
Injection is impossible, on the one hand, because the needle hole left by injection will become a channel for bacteria and mold to invade, and the fruit will rot easily.
On the other hand, injections can not guarantee the uniform distribution of sodium cyclamate in fruits, and may also affect the taste.
It is really not easy to put medicine in a solid fruit like watermelon.
If it is spray, it seems unlikely.
Sodium cyclamate is water-soluble and almost insoluble in organic solvents, so it is not easy to penetrate the waxy layer of fruit skin.
More importantly, even if the spray is absorbed on the surface energy, how to ensure that all the fruits of a tree are evenly absorbed?
In particular, fruits with thick skins, such as grapefruit and oranges, are absorbed from the epidermis and transferred to the pulp, which is not as simple as you think.
If you don't believe me, you can try chewing the peel to see if it is sweet, and you will be disappointed.
This cyclamate is not another cyclamate.
In fact, the "sodium cyclamate" mentioned by growers is probably not the food additive sodium cyclamate.
In the folk, XX element and XX essence are popular names, which refer to things that are efficient, powerful and quick-acting.
Because it can make fruit sweet, it is called sodium cyclamate. In fact, its scientific name is sweetener and sweetener, which belongs to plant growth regulator and foliar fertilizer sprayed on the surface.
It is the earliest technology developed by developed countries in Europe and America, and has been used in agriculture for decades.
There are many such commercial products, but the ingredients are different.
Common trace elements such as polysaccharides or polysaccharides, boron, molybdenum, zinc and manganese, rare earth elements (also commonly used as foliar fertilizers for tea), sodium thiosulfate, sodium sulfate and sodium sulfite.
These things are not sweet in themselves, but the principle is basically to improve fruit yield, shorten maturity and improve appearance quality by promoting plant metabolism and the synthesis and accumulation of nutrients.
Don't add sugar to late-maturing fruit?
For the same fruit variety, the fruit without sweetener may ripen later, but this does not mean that the late-maturing fruit does not need to be sweetened.
The ripening time of fruits and vegetables can be adjusted manually, such as sowing time and using growth regulators, but the most critical factor affecting the time to market of fruits and vegetables is the variety.
Take oranges as an example, if everyone's oranges are listed together, it will inevitably lead to oversupply in the market and no one will bid for them.
Therefore, people gradually cultivate varieties that mature in different periods. Through "off-peak commuting", the supply cycle of citrus can be extended, and the price can be relatively stable, so that it will not be listed together and hurt farmers.
Therefore, late-maturing fruits don't need sweeteners at all, just wishful thinking.
Why is the fruit we eat so sweet?
Sweetness means sugar and energy. The pursuit of sweetness is deeply rooted in genes and is an animal instinct in the process of evolution.
Because everyone loves sweet food so much, fruit breeding is developing in a bigger and sweeter direction.
After the cultivation of generations of agricultural scientists and technicians, fruits have become more and more sweet, and even corn and potatoes have cultivated sweet varieties (non-transgenic).
If the fruit is not sour, it means that there is something wrong with others, and agricultural scientists and technicians are really going to cry.
But as the saying goes, carrots and vegetables have their own tastes, and sour fruits have no market. Some people like sour fruit.
There is a very vivid joke that an elder sister went to buy oranges and asked the stall owner, "Is this orange sweet?" The stall owner enthusiastically replied, "It's very sweet, not sour at all", and the elder sister pursed her lips, "Forget it, I like sour".
Fruits that have really been treated with sweeteners.
It is almost impossible to use sweeteners (such as saccharin and sodium cyclamate) in the planting process, but it is still possible in the intermediate circulation and sales process, such as the famous "saccharin jujube".
Unfortunately, soaking dates with saccharin is useless for eggs, which is just a cover for vendors. Saccharin is difficult to penetrate the dense jujube peel and can only sweeten the outer layer.
Red dates turn red not because of saccharin but because of warm water.
Similarly, some vendors will spray saccharin water on bayberry, mulberry and other fruits to make them sweet, which is also a distraction. If you taste it on the spot, it may be sweeter. Take it home and wash it with water, and the saccharin will be gone.
Therefore, I suggest you buy less roadside stalls. Although I can't eat anything wrong, I don't feel good about being cheated.
Believe what all farmers say.
Finally, I want to tell you, don't think that the candid video is the truth.
Don't look at what they say, but they know what it is and don't know why. Like contraceptives for cucumbers, seedless grapes also come from them.
How did the rumor come from? It is because the rumor-monger himself believed it.
Ok, I'll just watch you keep pretending ~ ~
