At present, the so-called sweet potato vermicelli sold in the market accounts for a large proportion. It can be said that fake vermicelli with cassava flour as raw material is basically used to walk around the streets for three rounds. There is another aspect that must be paid attention to. Because alum should be added to handmade vermicelli, and the amount of alum added is controlled, eating too much alum will cause Alzheimer's disease and juvenile osteoporosis, so handmade vermicelli is not necessarily a good vermicelli. In addition, you can refer to the following points when choosing vermicelli.
First, the color, sweet potato powder is generally yellow or light brown, the high-quality color is a little white, but the whole is dark. Now the cyan, green and pure yellow ones sold in the market are all added with pigments, whether they are sweet potato powder or not, they are not recommended; The vermicelli with cassava starch is red, especially after soaking, you can see a faint red color; At the same time, pay attention to the look and feel of vermicelli. It is not good to have black star impurities.
Second, the taste, the real sweet potato vermicelli has a faint sweet potato flavor, but after the cassava vermicelli is cooked, there is no seasoning, and the entrance throat is irritating, and it seems to be chewy, while there is too much corn starch, which is yellow but opaque and has corn flavor;
Third, the price difference. At present, the price of sweet potato in the market is 800-1one ton of 200 yuan, and about 6 tons of sweet potato can process one ton of starch. The price of sweet potato starch on the market is 3.5-4 Jin Yuan, and the processing cost of making sweet potato vermicelli is 1.5 yuan, so the cost price is about 5-2 6 yuan. The price of pure sweet potato vermicelli sold in the market is generally higher than that in 8 yuan, but there are many vermicelli on the market now.
