2. Do you have acne? Real sweet potato flour is difficult to mix with water, while other starches penetrate evenly, so it is difficult to have pimples in the vermicelli.

3, true sweet potato vermicelli will have different thickness. Because the water seepage of sweet potato powder is uneven, the vermicelli made is thick and thin. The vermicelli made of other starches is even in thickness.

4, true sweet potato vermicelli is easy to break. Sweet potato flour itself has no toughness, even in humid weather, the vermicelli will break at a discount, while the vermicelli made of other powders has good toughness and is not easy to break because of mixing gelatin.

5, true sweet potato vermicelli is tasteless. Fake vermicelli has a special smell of smelly ink because of the addition of dye or ink.

6. True sweet potato vermicelli is easy to break, while vermicelli made of other powders is tough.

7. If you carry a lighter with you, the real sweet potato vermicelli will swell after burning, and it will neither become a hard ball nor completely become powder.
