It turns out that sweet potato vermicelli is also fake, how to easily distinguish it?

When sweet potato vermicelli is made by docking, it is mainly formed by beating sweet potatoes into starch, then boiling them at high temperatures, and drying them. Sweet potato vermicelli is very resistant to boiling and has a smooth texture, so it is loved by many people. When sweet potato vermicelli is made by docking, we can fry it, or it can be eaten cold, hot pot, etc., which are particularly delicious.

I don't know which way you like to cook sweet potato vermicelli?

Now that it has entered winter, many people like to eat hot pot at home, and when they are hot pot, they can have some sweet potato noodles, not to mention how refreshing the taste is. Although sweet potatoes are delicious, you should also pay attention when buying them, because some sweet potato vermicelli bought on the market are fake sweet potato vermicelli. So today I'm going to share with you some ways to distinguish sweet potato vermicelli, which was taught to me by an employee of a flour mill, and if you master this trick, you can easily distinguish between real and fake sweet potato vermicelli.

1. Look at the color

There are two main kinds of sweet potato vermicelli on the market, one is in the shape of a long strip, and the other is knotted. These two kinds of sweet potato vermicelli are their colors, one is gray and the other is yellow. When buying these vermicelli, remember to take a look at their color, the purer the color, the more fake the vermicelli.

Real sweet potato vermicelli, its color is dark and light, and there will be a lot of impurities in it, it looks like bad vermicelli, in fact, this kind of vermicelli is just the best.

Second, break it

The second point is that when buying sweet potato vermicelli, we remember to break the sweet potato vermicelli with our hands to feel its toughness. If the vermicelli crumbles as soon as it is broken and is not very crisp, it is a particularly pure sweet potato vermicelli. There are no food additives in the vermicelli, nor does it contain any gelatin.

If you encounter vermicelli that is broken by hand, it is difficult to break it, and it looks particularly tough, such sweet potato vermicelli should be especially vigilant, it may have a lot of gelatin added to it. So when you buy sweet potato vermicelli, you should buy the kind that is easy to break.

3. Smell it

Finally, when buying sweet potato vermicelli, you must remember to use your nose to smell the sweet potato vermicelli and the flavor it contains. Pure sweet potato vermicelli, if you smell it with your nose, you will be able to clearly feel it, with a faint sweet potato fragrance. If the sweet potato vermicelli you encounter smells foul or has a moldy smell, then the sweet potato vermicelli may have gone bad.

If it is not with a plastic smell, you must not buy such sweet potato vermicelli, this kind of vermicelli is the worst.

When making sweet potato vermicelli, hot and sour noodles are the most common method, just soak the sweet potato vermicelli in warm water, and then boil it with hot water. Then prepare a small bowl of hot and sour sauce, then add the vermicelli to the sauce, and add some fried peanuts, a few slices of ham sausage, and a pinch of coriander.

Fold by hand: Sweet potato flour is made of sweet potato starch, which is very brittle after drying, and it will break when folded by hand, and it is not easy to return to moisture when dried. Glue is added to the fake sweet potato flour, and it is constantly folded.

Look at the price; The price of real sweet potato flour is more than 10 yuan, because it has to be processed through multiple procedures, and fake sweet potato flour is between 2 and 3 yuan, so it is not recommended to buy.

Most of the sweet potato vermicelli sold on the market is not made of pure sweet potato flour, many people in the north make their own at home, fake sweet potato vermicelli is divided into two kinds, one is particularly soft and crispy, not strong, and it will be broken when cooked, and the other is similar to the real one, stronger than the real one, and it is not rotten after cooking for a long time, and it is put with edible gum.

Sweet potato flour is cloudy in color, and fake vermicelli is white and transparent in color. Generally, sweet potato flour is relatively thick.

Look at the color of the real fries are relatively dark yellow, but not very white, if it is very white, it may be mixed with starch. Real sweet potato vermicelli is not tough, it breaks easily, and it is relatively crispy. If it is not easy to break, it is most likely adulterated.

See if there is toughness, the real vermicelli is not tough, he will break easily. And it is relatively brittle, in humid weather, the vermicelli is also broken as soon as it is broken, if it is not easy to break, then the vermicelli is adulterated, and the gelatin added to it is not easy to break.

To distinguish the authenticity of sweet potato vermicelli, you can learn from itcolor, see if there is toughness, smell the taste, look at the condition after cookingand other aspects to distinguish, the specific content is as follows:

1. Look at the color

In fact, the color of real fries is darker, because there are different varieties of sweet potatoes, so the color is also different. The general color is mostly off-white and brown. But it won't be very white, and if it's the kind that is very white, it's likely that it's adulterated with starch.

Don't buy that one.

2. See if there is toughness

Real sweet potato vermicelli is not tough, it will break easily from an aesthetic point of view, and it is relatively brittle, even in more humid weather, the vermicelli will break as soon as it breaks. But if it is not easy to be broken, it is very likely that it is adulterated, and gelatin will be added to it, so the sweet potato vermicelli will not be easy to break, and such sweet potato vermicelli is fake.

3. Smell the smell

Normal real sweet potato noodles will not have any peculiar smell, only a faint taste of sweet potatoes, I don't know if you have carefully discovered, if the taste of mold, this kind of sweet potato flour is best not to buy, because it has been a long time for him. If you observe that sweet potato vermicelli has a peculiar smell, then there is a good chance that it is not a real sweet potato vermicelli. So you can smell more when you buy sweet potato vermicelli.

4. Look at the situation after cooking

Pure sweet potato vermicelli will become very soft and chewy after cooking, and its water absorption ability will also become very strong, and the thickness can increase to 2 times the original, while fake sweet potato vermicelli does not have such a large expansion index, it will become smaller, and most vermicelli cannot be chewed.

5. Burn with fire

Another way is to light the sweet potato flour with a lighter, the speed of burning is very fast, and after burning, it will expand a little, it will not become a hard ball, and it will not completely become a powder, then it means that it is really sweet potato vermicelli; If the burning rate is very slow, there is a peculiar smell after burning, and it will turn into powder, then it means that it is fake.

Let's take a look at a picture to compare the appearance color of real and fake sweet potato flour (as shown below), if there are no real and false vermicelli put together to distinguish, it is difficult to distinguish with color and other appearances, so the most reliable way is to burn with fire, put the vermicelli horizontally horizontally, the fake vermicelli fire will be extinguished as soon as it is removed, it is not easy to burn, the ash hand feels grainy, the innocent vermicelli fire will continue to burn, the ash hand touches the delicate, just like the grass ash, and when burning, you will hear the explosion sound, A small amount of ash will float into the air, and it is pure sweet potato vermicelli.

Secondly, it can also be referred to on **, less than 15 yuan basically do not need to be considered, especially the kind of average **5 yuan a catty, the market price of sweet potato starch is 15 a catty! Of course, it doesn't mean that expensive is necessarily true, but it can only be said that a few dollars a pound must be fake! Next, let's talk about distinguishing the real from the fake, as shown in the following figure:

Observe the color of the vermicelli. Generally speaking, real sweet potato vermicelli should be translucent dark cyan or slightly yellow, not the more transparent the better.

See if there are any gnocchi. Real sweet potato flour is difficult to mix well with water, so no matter how hard you try, there will be small gnocchi in the noodles. Other starches seep evenly, and it is difficult to have gnocchi in the noodles made.

If you look closely, real sweet potato vermicelli will have different thicknesses. For the same reason as the previous one, because the sweet potato flour is not evenly permeable, the noodles made are thick and thin. The vermicelli made of other starches is uniform in thickness.

Real sweet potato vermicelli is easy to break. Sweet potato flour itself is not tough, and even in wetter weather, the vermicelli will break as soon as it breaks. When we were kids going to school, we passed by the site where the vermicelli was dried, and there were always a lot of broken vermicelli on the ground to eat.

The vermicelli made of other powders is not easy to break because it is mixed with gelatin, which is tough.

Smell the smell. Real sweet potato vermicelli has no taste. Some counterfeit vermicelli have a special smell of stinky ink because of the addition of dyes or ink.

Look at the number of "noses". When the vermicelli is dried, it is all rod by rod, so there is a "nose". Real sweet potato vermicelli is relatively easy to break, so there is only one layer, and there will never be two "noses" in one vermicelli.

The vermicelli made of other flour is very long because of its toughness, and there are many "noses". If you find that a vermicelli has two noses, you can basically conclude that it is not a real sweet potato vermicelli.

If you have a lighter with you, you can burn it. Real sweet potato vermicelli will swell a little after burning, and will neither become a hard ball nor completely become a powder.

Sweet potato flour is delicious, do you know how to choose when you buy it? Let's share some methods with you, let's learn together.

How to distinguish a real sweet potato vermicelli from a fake? Teach you a few tricks, easy to distinguish fake vermicelli, what you don't know, life tips, life tips, life tips.

Let's teach a few simple methods, first, water.

Boil: After boiling, the sweet potato vermicelli should be slightly yellow and transparent, not white, and not too easy to break. Second, touch it with your hands: the surface of handmade sweet potato vermicelli is not so smooth, not as smooth as machine vermicelli.

Third, taste it: handmade sweet potato vermicelli, take one and chew it slowly in your mouth, taste it carefully, there will be a slight sweet potato sweetness. Amoy. /.Treasure has a home.

Chunfeng vermicelli.

First, we can take a look at the color of sweet potato vermicelli. If the sweet potato vermicelli is translucent, it means that it is a real sweet potato vermicelli. However, if the color of the sweet potato vermicelli is completely transparent, it means that the sweet potato vermicelli is likely to be fake.

Secondly, we can use fire to burn sweet potato vermicelli. If the smell is a little pungent, then the vermicelli may be fake. However, if the flavor of the burnt is faint, then this sweet potato vermicelli should be real.

You can judge by the state of the main time, and the sweet potato vermicelli will not be particularly sticky after it is soft.

It can be judged according to the taste, it can be judged according to the color, and the sweet potato vermicelli is more elastic, so it can be judged in this way.

I've met particularly unscrupulous sellers who buy fake vermicelli and replace them with tapioca flour, and may also add certain chemicals, such as formaldehyde or gum additives, to increase the tender taste of the gluten and extend the shelf life.

When making sweet potato vermicelli, in addition to stealing beams and changing pillars, some merchants will also add a large amount of alum as a bulking agent, which will cause adverse effects on the body when eaten regularly. There are also some merchants who will add borax, gelatin, and even formaldehyde to improve the taste and gluten of the vermicelli.

So, how to identify such fake merchants?

1: First of all, we keep in mind a sentence, you get what you pay for, expensive is not necessarily good, but cheap is definitely not good. The sweet potatoes on the market cost 2-3 yuan a catty, and they are sold for 2-3 yuan after being made into vermicelli.

Remember, there's no good thing with cheap money.

2: Then it smells the taste, the authentic sweet potato flour has no taste, if you smell a plastic smell or an ink smell when purchasing, it is basically concluded that it is a fake sweet potato flour. Generally speaking, the color of real sweet potato flour will be a little yellowish, but if you find that the vermicelli looks transparent and the color is relatively uniform, this may be with edible gum.

3: You can also try to burn it, after the authentic sweet potato flour is burned, there will be a burnt smell, but if there is black smoke or a bad smell, this is generally fake vermicelli. If it is pure powder, it means that it is real sweet potato powder, if there are particles, it may be a fake sweet potato powder.

1. Toughness: Dried sweet potato vermicelli is very crispy, breaks when grabbed by hand, and is not easy to regain moisture. And counterfeit sweet potato vermicelli with gelatin will not break if you are exposed to the sun for many days. There is always crumbs in the end of the noodles.

2. Resistant to cooking: The more sweet potato vermicelli is soaked, the more it will be soaked, half a bowl will become a bowl, and the gelatin vermicelli will not be able to do it, and the pure sweet potato vermicelli will not become a pot of slag when it is made with meat in the pressure cooker, and the sweet potato dregs and flour will not be reached.

3. Taste. Most of the real sweet potato flour is made of sweet potatoes, and it is all starch, so it doesn't smell good, while the adulterated sweet potato flour is mostly made of chemicals such as gelatin, so the smell is a little unpleasant, and you must pay attention to it when you buy it.

1. Look at the appearance of the vermicelli

To buy sweet potato vermicelli, the first thing is to take a look at the appearance of the vermicelli, the real pure sweet potato vermicelli is generally made of sweet potato starch, according to the different sweet potato varieties and starch quality, the vermicelli will be brownish in color from the appearance, even yellow, blue, the color will not be particularly bright, nor will it be particularly transparent.

2. Smell the vermicelli

Pure sweet potato vermicelli generally does not have any special smell, if the purchased vermicelli smells unpleasant, then you should pay extra attention to the vermicelli, indicating that some kind of chemical ingredient is likely to be added to the vermicelli.

3. Look at the toughness of the vermicelli

Real pure sweet potato vermicelli, after natural drying, will become particularly brittle, generally can be broken lightly by hand, there will also be broken vermicelli, if the purchased vermicelli is distinct, it is difficult to break it by hand, it may be added gelatin or something like that, so when buying vermicelli, be sure to fold it in half by hand, and judge the authenticity of the vermicelli according to the toughness of the vermicelli.

4. Burn the vermicelli over fire

When buying vermicelli, you can also use a lighter to burn the vermicelli to identify the authenticity of the vermicelli, if it is a real sweet potato vermicelli, it will naturally expand after ignition, after burning, you will smell a burnt fragrance, the ashes after burning, twist it by hand, there is no graininess, if it is adulterated sweet potato vermicelli, black smoke will come out when burning, and the smell will be very unpleasant after burning. The ashes after burning will have a fine grainy feel when touched by hand, and they are not very smooth.

5. Look at the cooking resistance of the vermicelli

Pure sweet potato vermicelli is generally more resistant to cooking, and it takes about 5 to 10 minutes to cook after cooking. If the vermicelli is rotten after a little boiling, it must not be pure sweet potato vermicelli, if it is not rotten after a long time of cooking, and it tastes hard core, most of it is mixed with edible gum, and it is not really sweet potato vermicelli.
