How to distinguish true and false sweet potato fans
The real pure sweet potato vermicelli is made of pure sweet potato starch, which is easy to break and brittle. According to the production process, different colors are white and beige, all of which are translucent. It won't be too strong, but it won't cook for long. It usually takes about ten minutes to smell the sweet potato when cooking. Fake vermicelli is mainly added with other cheap starch to reduce the cost, followed by additives such as edible gum, so as to achieve a rich and lasting taste. Therefore, strong, smooth and boiling-resistant vermicelli is not necessarily a good vermicelli!
Is this a sweet potato fan? How to tell the truth of sweet potato vermicelli?
At present, there are only three kinds of vermicelli on the market, one is machine-made vermicelli (made by machine extrusion, which is high in density and resistant to cooking, but the other is not easy to taste and will be pulled together after a while), and the other is handmade vermicelli (it is really handmade, and it is generally made by itself in rural areas, and it has advantages by directly using starch; The density of vermicelli is low, which is easy to taste and will not stick. There are many impurities and it is unsanitary. Alum used by farmers is expensive. Now there is a kind of handmade flour (the principle of making is the same as that of handmade flour, except that machines are used instead of labor). Advantages are the same as handmade flour. If the regular factory has starch purification, it will be cleaner and healthier, and the regular factory will not add additives such as alum. Disadvantages; There are too many fake enterprises, and you can't find what you want to buy. )
To tell the truth, my family is a vermicelli manufacturer. Our products are pure sweet potato vermicelli without any additives. But the market doesn't recognize it, the boss wants to buy it, and the domestic distributors don't want to make it ... because the vermicelli sold is expensive and costly, it is still unknown whether it will make money ... so they would rather sell low-end products ... Here, I advise you not to think that the vermicelli produced in rural areas is good, and the hard-boiled vermicelli is good. The vermicelli without alum is boiled in a boiling water pot for 10 minutes, and it will be broken in the second meal. The landlord really wants to eat. I can mail it to you for free ... so that the landlord can eat the rest assured vermicelli. Ha ha. QQ:254220479
