How to distinguish between real and fake sweet potato flour, how to distinguish real and fake sweet

1. Look at the color.

First of all, when we buy sweet potato powder, the first thing is the color of sweet potato powder, in the market we often see that the color of some sweet potato powder is very bright, when encountering such sweet potato powder, we must not let its appearance be confused, because such sweet potato powder, most of them have added a lot of food additives. The color of real sweet potato flour looks gray and not very transparent, and it is translucent and looks dark.

Second, look at resilience.

When buying sweet potato flour, we can also use our hands to gently fold the sweet potato flour, if the sweet potato flour is easy to break, it proves that such sweet potato flour is the best, and the sweet potato flour encountered, if its toughness is particularly strong, then it is best not to buy such sweet potato flour, because the real sweet potato flour is actually relatively poor.

3. Smell the smell.

Smelling the taste is also the best way to distinguish sweet potato powder, and it is also the most practical method, because most of the real sweet potato powder is made of sweet potatoes, which is rich in starch inside, just smell it with your nose, you can feel the faint sweet potato fragrance, if it is fake sweet potato powder, in order to improve its preservation time, when the manufacturer makes it, it will add some preservatives to it, and these preservatives will make the taste of sweet potato powder smell particularly bad. So, when we are buying sweet potato flour, remember to smell it with our nose.

Fourth, whether there are gnocchi.

Real sweet potato starch is very difficult to be stirred by water when it is stirred. Therefore, no matter how you make sweet potato flour, the sweet potato flour will have some small gnocchi on its surface, and it will not be particularly smooth. If you buy sweet potato flour, on its surface is particularly smooth and delicate, then 80% of such sweet potato flour is fake, not the more beautiful the appearance of the ingredients, it is good, although the appearance is not good, but such ingredients are the best.

5. Burn with fire.

If the taste of the burnt is a faint fragrance, then such sweet potato powder is the most authentic, if the taste of the burn is burnt and smelly, then such sweet potato powder must have added a variety of food additives inside, and its flammability is particularly high, it is easy to be ignited, and it is difficult to extinguish. Not only that, after the burning of good sweet potato flour, the remaining ashes are not grainy and are particularly delicate.

Water test method: take a small amount of starch, put it in a glass of water, stir and let it stand for a while, the pure starch will quickly precipitate, and the water will still be clear; The water on top of the adulterated starch is cloudy.

Dry evaluation method: that is, use your eyes to observe whether the starch color is white and whether there are impurities; whether there is a peculiar taste in the mouth; Whether there is a slippery feeling when rubbing by hand.

Water sinking method: take a small amount of starch and add water to dissolve it in a transparent cup to see if there are impurities to see if it can be precipitated and compacted.

Cooking method: also take a small amount of starch and add water to dissolve, after cooking, smell whether there is any peculiar smell, taste whether there is wheat flour flavor, rice flour flavor or other peculiar smell, to see if the color is normal; Stir while hot to see if the tendon strength is good. If it is undecolorized, the starch will be dark brown or gray, and if it is pure sweet potato starch, it will have good strength and softness.

Teach you a way to distinguish real sweet potato flour from fake, and never eat fakes again!

Sweet potato flour is a home-cooked dish made from sweet potatoes. The content is starch, which is a coarse grain product, and regular consumption is conducive to nutritional balance, improving intestinal peristalsis, and facilitating laxation. It is one of everyone's favorite dishes in daily life.

However, the products on the market are uneven, some are true and some are fake. Xiao Yoyo is here to introduce you to the easiest way to identify. That is, bring a lighter, when you are ready to buy sweet potato flour, fold a small piece and light it, if it makes a clicking sound when burning, and it is as white as popcorn, it is real, and when you light it, if it emits black smoke and has an unpleasant smell, it must be fake.

Look at the color. Many people think that the brighter the color of the sweet potato powder, the better, in fact, this method of judgment is misplaced, the owner of the powder shop told me that usually the brighter color of the sweet potato powder is added with some additives, or industrial gelatin and the like, and the real vermicelli color will be a little turbid, translucent dark cyan, so when you buy sweet potato powder, you should be cautious when you encounter a particularly bright and transparent color.

2. Look at resilience.

The toughness of real sweet potato flour is actually relatively poor, and it is usually easy to break when it is broken, while the adulterated sweet potato flour has very good toughness, and it is difficult to break on the substrate, because most of the fake sweet potato flour is mixed with gelatin, so when you buy sweet potato flour, you must pick up one to try the toughness.

3. Smell the smell.

Adulterated sweet potato flour has a bad smell and a strong chemical smell that smells a bit similar to the smell of ink, while real sweet potato flour has no taste because the ingredients inside are all starch and are made from real sweet potatoes.

4. Burn vermicelli.

Take a sweet potato vermicelli for fire, just use a lighter to burn the broken part of the vermicelli, if the vermicelli will burn out the cereal flowers, and there is a very fragrant burnt smell, not a stinky burnt smell, it means that this is a real sweet potato flour, but if the vermicelli keeps burning, and exudes a strong smell of burning, it means that this is adulterated sweet potato flour.

5. Rub the vermicelli soot.

After burning the vermicelli, some soot will be left, we can distinguish the authenticity of the vermicelli through the soot, generally the soot left over from the burning of real sweet potato flour is relatively soft, and there is no grain when rubbing, while the adulterated vermicelli soot has a rough frosty feeling to the touch.

The above is the method that the owner of the powder shop taught me to distinguish the authenticity of sweet potato flour, I hope these tips can help you, remember, when selling sweet potato flour, pay attention to these 5 places, whether it is true or false at a glance.

1. When buying sweet potato vermicelli, first of all, don't choose the color that is too bright, because most of the sweet potato flour that is too bright and good-looking has additives added to it.

2. When buying sweet potato vermicelli, first break the vermicelli by hand to see how the toughness of the vermicelli is, if it is broken lightly, sweet potato vermicelli like this means that there is no gum in it, but the toughness of the adulterated sweet potato vermicelli will be very good, even if it is very hard, it is constantly folded.

3. You can also smell the taste of sweet potato noodles, real sweet potato noodles actually don't have any taste, but if it is doped in sweet potato noodles, because some chemicals are used, we will have a particularly pungent smell when we smell it.

4. In addition, you can use an open flame to burn the vermicelli, if the vermicelli is ignited and expands rapidly, it will not make any sound, indicating that such sweet potato vermicelli is real, but on the contrary, it is fake, when boiling sweet potato vermicelli, high-quality sweet potato vermicelli is very resistant to cooking, and it is still hard after boiling inferior sweet potato flour, and there is no elasticity.

There are many types of vermicelli, but my favorite is sweet potato vermicelli. But in our lives, there are many adulterated phenomena of sweet potato vermicelli, and if you don't choose carefully when buying vermicelli, it is easy to buy inferior fake vermicelli. These fake vermicelli not only taste good, but also affect your health if you eat them regularly, so we must pay extra attention when choosing and don't buy fakes.

When buying vermicelli, the first thing to do is to observe the shape of the sweet potato vermicelli. Generally, the surface of high-quality sweet potato vermicelli will not be too smooth, and there will be some raised small particles or small white spots, which is normal, because sweet potato starch is not easy to melt. And the smoother the surface, the more translucent the color, and the more light the color of the sweet potato vermicelli, the more careful you should be.

Because such sweet potato vermicelli is likely to be added with vegetable gum, the content of sweet potato flour is extremely low, so it is not recommended to buy it.

2. Whether it is easy to break.

Take a sweet potato vermicelli and fold it gently, if it is easily broken and makes a crisp sound, it means that it is normal and you can buy it with confidence. If the vermicelli is particularly difficult to break, it means that a large amount of edible glue has been added to the vermicelli, which is a fake vermicelli. Fake vermicelli not only tastes bad, but eating too much will also have an impact on your health, so don't buy it.

3. Burn with fire.

Another trick to buy sweet potato vermicelli is to recommend that you bring a lighter with you when you go to buy vermicelli. When buying vermicelli, take a vermicelli and burn it over a fire. If it's fake sweet potato vermicelli, the heat will go out, it's not flammable, and the ashes feel grainy to the touch.

And the real sweet potato vermicelli will always burn even if the fire is withdrawn, and there will be a crackling sound when burning, the ashes are more delicate to the touch, and a small amount of ash will float into the air, which is the real sweet potato vermicelli.
