You can tell the authenticity of vermicelli by looking at its color and toughness. Look at the color

In fact, the color of real French fries is darker. Because the varieties of sweet potatoes are different, the colors are also different. Generally many colors are off-white and brown. But it won't be very white. If it is very white, it is probably mixed with starch, so don't buy it. Check to see if it has toughness

Real sweet potato vermicelli is not tough and will easily break the aesthetic point of view, and it is relatively brittle. Even in humid weather, the vermicelli will break as soon as you break it. But if it doesn’t break easily, it’s probably adulterated and gelatin is added inside, so the sweet potato vermicelli won’t break easily. Such sweet potato vermicelli is fake. Smell

Normal sweet potato vermicelli will not have any peculiar smell, only a faint sweet potato smell. I don’t know if you have noticed it carefully. If there is a moldy smell, it is best not to buy this kind of sweet potato vermicelli because it has been there for a long time. If you observe a strange smell in the sweet potato vermicelli, there is a good chance that it is not genuine sweet potato vermicelli. What should I pay attention to?

When buying vermicelli, if you carry a lighter with you, you can use the lighter to burn the vermicelli to identify the authenticity, which is also a relatively simple and effective way. If the vermicelli is of good quality, it will slowly expand when burned with a lighter. After burning, you will smell a faint aroma and can continue to be chewed in your mouth. If the vermicelli is mushy and obviously powdery, then the vermicelli is of inferior quality, most of which are made of edible glue. If good vermicelli is not easy to break when folded, it is inferior quality vermicelli, because most of the vermicelli that is not easy to break are artificially synthesized with edible glue, which looks particularly like plastic. You can also look at the color of the vermicelli. If you see that the vermicelli is completely transparent when you buy it, then the vermicelli made with edible glue is of inferior quality and cannot be purchased. And there are obvious bubbles and lumps in the vermicelli. Although the appearance is not very good, the quality is good. Therefore, when buying vermicelli, we must pay attention to the above points I mentioned.
