How to tell the truth of sweet potato vermicelli?

1, toughness: dried sweet potato vermicelli is very brittle, it will break by hand, and it is not easy to regain moisture. The fake sweet potato vermicelli of gelatin will not break after being exposed to the sun for many days. There will always be crumbs at the end of the fans.

2, cooking resistance: the more sweet potato vermicelli is soaked, the half bowl will become a bowl, and gelatin vermicelli can't do it. Pure sweet potato vermicelli cooked with meat in pressure cooker will not turn into a pot of residue, but it can't be achieved with sweet potato residue and flour.

3. Taste. The real sweet potato powder is mostly made of sweet potato, which is full of starch and smells tasteless, while the adulterated sweet potato powder is mostly made of chemicals such as gelatin, so the smell is a bit unpleasant. Be sure to pay attention when buying.

Extended data:

The color difference between sweet potato vermicelli and vermicelli is still obvious. According to experience, the yellow and blue vermicelli of pure sweet potato are all true, and there is also a kind of white and transparent vermicelli that is true. It is not only black vermicelli that everyone thinks is true. This is actually a misunderstanding. Regarding the blackening of vermicelli, I also asked the master who made handmade vermicelli.

According to them, this has a lot to do with the quality of sweet potato starch. In the process of making sweet potato starch, there will be something called "dry powder", which floats on sweet potato starch and is not easy to clean. If there is a lot of "dry powder" in sweet potato starch, the color of vermicelli will turn black. Old people who make vermicelli in rural areas are reluctant to throw away the "dry powder strips" and deliberately mix them in. Over time, people think that only black vermicelli is true. Sweet potato vermicelli is wide, thin and nutritious. Like sweet potato, it is an anti-cancer food. Suitable for boiling, frying and cold salad.
