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.

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.

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.

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.
