Because sweet potatoes are rich in polyphenols and polyphenol oxidase, sweet potato starch is easily oxidized and browned to produce melanin, and the sensory quality and commodity value of starch products produced by static starch and its processing have been seriously affected and restricted. In order to solve this problem, some manufacturers use the method of adding chemical reagents to make up for the above shortcomings. However, practice shows that the added chemical reagents sulfite, citric acid, ascorbic acid (VC), boron, zinc compounds and bleaching powder have strong residual toxicity, which not only destroys the quality and process characteristics of starch, but also has a long precipitation cycle, low equipment utilization rate and poor product quality.
5 to 8 hours, wait for the water on it to become completely clear, too early precipitation is not in place.

There is no harm. Sweet potato vermicelli is now a food that we are familiar with, sweet potato vermicelli is used in the cooking of many foods, it is the soul of many dishes, plus the taste and texture of sweet potato vermicelli is really good, so it is loved by many people, but although sweet potato vermicelli is good, there will be taboos and hazards when eating, let's take a look.
Sweet potato vermicelli is also harmful, so take it with care.
Sweet potato vermicelli is a strip-shaped pasta made from sweet potatoes, which is not harmful to the human body. However, there are some unscrupulous businessmen in the market who mix industrial alum into sweet potato vermicelli when making them, which can make processing more convenient and increase palatability. However, although the sweet potato vermicelli doped with industrial alum is full of tendons, it is also full of harm.
Because the chemical composition of alum is potassium aluminum sulfate, containing aluminum ions, and excessive intake of aluminum ions will affect the absorption of iron, calcium and other components by the human body, resulting in osteoporosis, anemia, and even affect the development of nerve cells, causing symptoms such as Alzheimer's disease, memory loss, and mental decline.
And because sweet potato vermicelli is made from sweet potatoes, it will also inherit some taboos of sweet potatoes, so sweet potato vermicelli and persimmon should not be eaten at the same time in a short period of time, and if there is a large amount of food, it should be at least five hours apart. If we eat it at the same time, because the sugar in the sweet potato vermicelli is fermented in the stomach, it will increase the secretion of gastric acid, and the tannin and pectin in the persimmon will react to precipitate and coagulate, resulting in hard lumps, which can make gastrointestinal bleeding or cause gastric ulcers when the amount is serious. If you feel sick to your stomach, you must go to the hospital for a gastroscopy to see if there is stomach bleeding or stomach ulcers, so sweet potato vermicelli and persimmons are not suitable to eat together.
Although sweet potato vermicelli tastes good and has high nutritional value, there will be certain hazards and contraindications when eating sweet potato vermicelli, so we need to be careful, first of all, we need to eat sweet potato vermicelli in moderation, and sweet potato vermicelli is not suitable for eating with persimmons, so that we can eat sweet potato vermicelli more healthily.
