Recently, the incident of Sister Yu's "sweet potato vermicelli mixed with cassava" was pushed to the hot search, and the manufacturer involved responded that its products did contain one-third of tapioca flour, which immediately aroused heated discussions among netizens.
In fact, it is not the first time that the adulteration of sweet potato flour has been exposed, in 2022, CCTV's "315 Gala" reported that some vermicelli factories in Yuzhou used tapioca starch to make sweet potato vermicelli.
So, when we usually buy sweet potato vermicelli, how should we distinguish the real from the fake?
For this reason, I carefully looked at a 62-year-old farmer, who had worked in a sweet potato vermicelli manufacturer before, and he said: Teach you 5 tricks to easily distinguish fake vermicelli.
1. Look at appearances
First of all, we can distinguish the real from the fake by looking at the appearance of the sweet potato vermicelli.
The old farmer said that the color of real sweet potato vermicelli should be translucent dark cyan or yellow, and there will be some small bumps and small bubbles on the surface.
This is because sweet potato vermicelli will go through steaming, stirring, squeezing and other processes during the production process, so there will be some irregular lines and bubbles on the surface.
Fake sweet potato vermicelli, on the other hand, are usually brighter in color and have a very smooth surface without any lines and bubbles.
This is because fake sweet potato vermicelli is usually made with tapioca starch or cornstarch, which has a more delicate texture, so the surface of the made vermicelli is also very smooth.
Second, fold it
Secondly, we can see if the sweet potato vermicelli is easy to break by folding it.
Real sweet potato vermicelli contains a certain amount of dietary fiber, so the texture is relatively flexible and not easy to break.
We can gently fold the sweet potato vermicelli with our hands, and if the vermicelli breaks easily, then it is likely to be fake.
Fake sweet potato vermicelli, on the other hand, are made with tapioca starch or cornstarch, so they have a crispy texture and are easy to break.
We can gently fold the sweet potato vermicelli with our hands, and if the vermicelli breaks easily and the fracture is very neat, then it is likely to be fake.
3. Smell the smell
Next, we can distinguish the real from the fake by smelling the sweet potato vermicelli.
Real sweet potato vermicelli should have a faint sweet potato aroma. This is because sweet potato vermicelli is made with sweet potato starch, so it will have a faint sweet potato aroma.
Whereas, fake sweet potato vermicelli, since they are made with tapioca starch or corn starch, do not have any sweet potato flavor.
We can smell the sweet potato vermicelli, and if the vermicelli doesn't have any flavor, or has a pungent chemical smell, then it's most likely fake.
Fourth, burn it
We can also see if sweet potato vermicelli burns easily by burning it over a fire?
Real sweet potato vermicelli is not easy to burn because it contains a certain amount of dietary fiber. We can use a lighter to light the sweet potato vermicelli, and if the vermicelli does not burn easily and there will be a faint sweet potato aroma after burning, then it is likely to be real.
Whereas, fake sweet potato vermicelli, since they are made with tapioca starch or cornstarch, they burn easily. We can light sweet potato vermicelli with a lighter, and if the vermicelli burns easily and has a pungent chemical taste after burning, then it is most likely fake.
5. Cook it
Finally, we can see the texture and texture of sweet potato vermicelli by boiling it in water.
Real sweet potato vermicelli contains a certain amount of dietary fiber, so the taste is relatively smooth and has a certain toughness. We can put the sweet potato vermicelli in boiling water and boil it for a while, and if the vermicelli has a smooth texture and some toughness when cooked, then it is likely to be true.
Fake sweet potato vermicelli, on the other hand, have a poor taste and don't have any toughness because they are made with tapioca or cornstarch. We can put sweet potato vermicelli in boiling water and boil it for a while, and if the vermicelli has a bad taste after cooking and does not have any toughness, then it is most likely fake.
The above 5 methods can easily distinguish between real and fake sweet potato vermicelli, we usually buy sweet potato vermicelli, we must pay more attention, you can observe the appearance, fold it, smell the taste, use fire and other methods to distinguish the real from the fake.
